Renewable Energy Persuasive Essay

Robert Caba

Dr. Freymiller

12 April 2016

Out with the Old, In with the Re(new)able

The United States has been operating as a country using limited fossil fuels, but what happens when it all runs out? Would it not be more beneficial to never find out? Renewable energy, energy that is not depleted after its use, is limitless and more sustainable than any other source in energy history. To initiate the clean energy movement is expensive, but there are countless benefits ranging from individual to global impacts in going completely renewable. The first recorded use of renewable energy was harnessing wind power to drive ships over water about 7000 years ago (Darling). However, renewable energy has been around as long as Earth has existed: wind, sun, geothermal, biomass and many more. Clean energy sources can be harnessed to produce electricity, process heat, fuel and other chemicals with significantly less impact on the environment. In 2014, renewable energy sources accounted for fourteen percent of America’s total electricity use (“Renewable Energy Sources”), a four percent incline from the prior year. Completely diverting from fossil fuels to renewable energy clearly is not a new concept for a select few of innovative countries. A few countries, for example, are Costa Rica, Norway and Iceland, all of whom have ran on renewable energy for the entire 2015 calendar year, diving deep into their own land’s resources and utilizing volcanic presence to produce energy (Rosecrance & Thompson 7). Following in the footsteps of Costa Rica and a few other third world countries, major economic powerhouses and biggest users of fossil fuels like the United States should convert to clean energy as a way to benefit the economy, environment and overall health of the country.

As a consumer, one is worried about how abandoning a safe form of energy and transitioning to something new can help or hurt their wallet. Not only can renewable energy help save money, it can also help make money. A 150 billion dollar investment into this new industry would result in 1.7 million job opportunities, reducing the unemployment rate in America by an entire percentage (Pollin & Heintz). The reason for the potential high employment rate is because the industry is labor intensive in the means of installation and maintenance, requiring a lot of manpower for ultimate success. However, the more we wait the more future benefits we are currently losing. In an American Solar Energy Association (ASES) report in 2009, they stated “the 2008 predictions for renewable energy industry in 2030 are significantly lower than the 2007 predictions (National Research Council 169).” Unlike fossil fuels, which are subject to volatile pricing fluctuating over time depending on the market, renewable energy is relatively “free” after installation, using natural resources. The process of transportation and maintenance is minimized allowing prices to stay constant throughout the years. The only way price can head is down; for instance, clean energy is more affordable than 25 years ago. In particular, wind energy, the fastest growing source of power, prices have declined from forty cents per kilowatt per hour to less than five cents per kilowatt per hour (“The Energy Story”), a remarkable change and a huge upside in favor of the conversion. As time continues, technology should continue its progression resulting in cheaper mediums to acquire the energy. Despite of this, the conversion should take place now so results are maximized for the future. All in all, clean energy can both save Americans money while help them make money, the perfect win-win for producers and consumers alike.

Abstaining from burning countless, yet limited fossil fuels every day and polluting the environment is the single biggest benefactor for moving towards a cleaner approach. Not only would greenhouse gas emissions, as well as other pollutants that cause smog and acid rain, reach minimal levels, but also the country is consequently assisting in the reduction of the global warming speed and effects. Unlike fossil fuels, which are unable to be replenished easily, renewable energy is limitless, feeding from natural resources. With the global and national population expected to continue rising, the demand for energy will follow. There is a multitude of different approaches to acquire renewable energy including the most used types: solar and wind power. Specifically, solar energy is the epitome of sustainability and efficiency, calculated through production and prices. Despite the massive amounts of energy used yearly nationwide, “the sunlight falling on the United States in one day contains more than twice the energy we consume in an entire year ( The Energy Story ).” As for wind power, “California [alone] has enough wind gusts to produce 11 percent of the world’s wind electricity ( The Energy Story).” Wind turbines take up a lot of space but still allow the area around it, usually farms, to be used regularly. In the United Kingdom, for comparison, the government set a target for renewable energy to make up 15 percent of their total energy expense by 2020. This motive results in a 34 percent cut in the country’s carbon emission in the same time span (National Research Council 180). Needless to say, renewable energy will make landmark strides in the progression towards a cleaner, better environment. The most important thing on this Earth is this Earth, and it’s society’s job to maintain it.

As well as helping the environment and wallets, renewable energy can help with everyone’s health. By cutting the emission of greenhouse gasses and fossil fuels, air pollution decreases. Air pollution, primarily those contributed through coal burning power plants emitting fine-particulate pollutants, is most associated with causing health problems, chiefly lung cancer. The Environment Protection Agency (EPA) predicts that conversion, or even standards, will prevent at least 100,000 heart attacks and asthma attacks per year. Additionally, EPA also estimates a projected 1,100 billion dollar income in health benefits due to avoiding illnesses and deaths (U.S. EPA). As a form of partnership, the health industry could invest a portion of this money into the clean air movement due to its beneficial health impacts and help make installation cheaper. A majority of these pollutants are associated with dangerous levels of climate change, this century’s biggest threat to human health. Climate change, a change in global climate patterns, “will increasingly jeopardize the fundamental requirements for health, including clean urban air, safe and sufficient drinking-water, a secure and nutritious food supply, and adequate shelter (World Health Organization).” Climate change is the main contributor and accelerator towards global warming. Global warming increases the risk of two deadly diseases: Plague and Ebola, to name a few. For Plague, changes in temperature and rainfall will affect rodent populations as well as the infected fleas they carry. Additionally, Ebola outbreaks tend to follow serious downpours or droughts, a likely result of climate change (Biello). The movement would not only lower the pollution rate and risk of infection, but also save countless lives across the globe during the process.

America, along with most other countries, needs to initiate their plans towards a more sustainable, cleaner form of energy. Renewable energy helps increase the production of the economy through the addition of million of jobs. Simultaneously, energy prices would be lower, also helping the consumer save money. However, it is vital to start now. The longer the wait, the less benefits are reaped. Likewise, the clean air movement will mark the beginning of recovery for the environment. Greenhouse gases and other emission will reach all time lows, possibly zero. This deduction is important to slow the rate of climate change and global warming. Stopping climate change and gas emissions in its tracks would also lead to more health benefits. There are dozens of deadly diseases and carriers that spawn from the irregular climate patterns. Also, climate change could affect physiological needs by lessening safe drinking water, food supply and shelter. The United States has a reputation of being an innovator, a leader for many countries. Why has it been so lackadaisical with something so important to everything in today’s society? It has a history of being scared of change; people are too comfortable with life as it is, but it could be better. With the United States recently moving in the right direction, it will be better.

Renewable energy, explained

Solar, wind, hydroelectric, biomass, and geothermal power can provide energy without the planet-warming effects of fossil fuels.

In any discussion about climate change , renewable energy usually tops the list of changes the world can implement to stave off the worst effects of rising temperatures. That's because renewable energy sources such as solar and wind don't emit carbon dioxide and other greenhouse gases that contribute to global warming .

Clean energy has far more to recommend it than just being "green." The growing sector creates jobs , makes electric grids more resilient, expands energy access in developing countries, and helps lower energy bills. All of those factors have contributed to a renewable energy renaissance in recent years, with wind and solar setting new records for electricity generation .

For the past 150 years or so, humans have relied heavily on coal, oil, and other fossil fuels to power everything from light bulbs to cars to factories. Fossil fuels are embedded in nearly everything we do, and as a result, the greenhouse gases released from the burning of those fuels have reached historically high levels .

As greenhouse gases trap heat in the atmosphere that would otherwise escape into space, average temperatures on the surface are rising . Global warming is one symptom of climate change, the term scientists now prefer to describe the complex shifts affecting our planet’s weather and climate systems. Climate change encompasses not only rising average temperatures but also extreme weather events, shifting wildlife populations and habitats, rising seas , and a range of other impacts .

Of course, renewables—like any source of energy—have their own trade-offs and associated debates. One of them centers on the definition of renewable energy. Strictly speaking, renewable energy is just what you might think: perpetually available, or as the U.S. Energy Information Administration puts it, " virtually inexhaustible ." But "renewable" doesn't necessarily mean sustainable, as opponents of corn-based ethanol or large hydropower dams often argue. It also doesn't encompass other low- or zero-emissions resources that have their own advocates, including energy efficiency and nuclear power.

Types of renewable energy sources

Hydropower: For centuries, people have harnessed the energy of river currents, using dams to control water flow. Hydropower is the world's biggest source of renewable energy by far, with China, Brazil, Canada, the U.S., and Russia the leading hydropower producers . While hydropower is theoretically a clean energy source replenished by rain and snow, it also has several drawbacks.

For Hungry Minds

Large dams can disrupt river ecosystems and surrounding communities , harming wildlife and displacing residents. Hydropower generation is vulnerable to silt buildup, which can compromise capacity and harm equipment. Drought can also cause problems. In the western U.S., carbon dioxide emissions over a 15-year period were 100 megatons higher than they normally would have been, according to a 2018 study , as utilities turned to coal and gas to replace hydropower lost to drought. Even hydropower at full capacity bears its own emissions problems, as decaying organic material in reservoirs releases methane.

Dams aren't the only way to use water for power: Tidal and wave energy projects around the world aim to capture the ocean's natural rhythms. Marine energy projects currently generate an estimated 500 megawatts of power —less than one percent of all renewables—but the potential is far greater. Programs like Scotland’s Saltire Prize have encouraged innovation in this area.

Wind: Harnessing the wind as a source of energy started more than 7,000 years ago . Now, electricity-generating wind turbines are proliferating around the globe, and China, the U.S., and Germany are the leading wind energy producers. From 2001 to 2017 , cumulative wind capacity around the world increased to more than 539,000 megawatts from 23,900 mw—more than 22 fold.

Some people may object to how wind turbines look on the horizon and to how they sound, but wind energy, whose prices are declining , is proving too valuable a resource to deny. While most wind power comes from onshore turbines, offshore projects are appearing too, with the most in the U.K. and Germany. The first U.S. offshore wind farm opened in 2016 in Rhode Island, and other offshore projects are gaining momentum . Another problem with wind turbines is that they’re a danger for birds and bats, killing hundreds of thousands annually , not as many as from glass collisions and other threats like habitat loss and invasive species, but enough that engineers are working on solutions to make them safer for flying wildlife.

Solar: From home rooftops to utility-scale farms, solar power is reshaping energy markets around the world. In the decade from 2007 and 2017 the world's total installed energy capacity from photovoltaic panels increased a whopping 4,300 percent .

In addition to solar panels, which convert the sun's light to electricity, concentrating solar power (CSP) plants use mirrors to concentrate the sun's heat, deriving thermal energy instead. China, Japan, and the U.S. are leading the solar transformation, but solar still has a long way to go, accounting for around two percent of the total electricity generated in the U.S. in 2017. Solar thermal energy is also being used worldwide for hot water, heating, and cooling.

Biomass: Biomass energy includes biofuels such as ethanol and biodiesel , wood and wood waste, biogas from landfills, and municipal solid waste. Like solar power, biomass is a flexible energy source, able to fuel vehicles, heat buildings, and produce electricity. But biomass can raise thorny issues.

Critics of corn-based ethanol , for example, say it competes with the food market for corn and supports the same harmful agricultural practices that have led to toxic algae blooms and other environmental hazards. Similarly, debates have erupted over whether it's a good idea to ship wood pellets from U.S. forests over to Europe so that it can be burned for electricity. Meanwhile, scientists and companies are working on ways to more efficiently convert corn stover , wastewater sludge , and other biomass sources into energy, aiming to extract value from material that would otherwise go to waste.

Geothermal: Used for thousands of years in some countries for cooking and heating, geothermal energy is derived from the Earth’s internal heat . On a large scale, underground reservoirs of steam and hot water can be tapped through wells that can go a mile deep or more to generate electricity. On a smaller scale, some buildings have geothermal heat pumps that use temperature differences several feet below ground for heating and cooling. Unlike solar and wind energy, geothermal energy is always available, but it has side effects that need to be managed, such as the rotten egg smell that can accompany released hydrogen sulfide.

Ways to boost renewable energy

Cities, states, and federal governments around the world are instituting policies aimed at increasing renewable energy. At least 29 U.S. states have set renewable portfolio standards —policies that mandate a certain percentage of energy from renewable sources, More than 100 cities worldwide now boast at least 70 percent renewable energy, and still others are making commitments to reach 100 percent . Other policies that could encourage renewable energy growth include carbon pricing, fuel economy standards, and building efficiency standards. Corporations are making a difference too, purchasing record amounts of renewable power in 2018.

Wonder whether your state could ever be powered by 100 percent renewables? No matter where you live, scientist Mark Jacobson believes it's possible. That vision is laid out here , and while his analysis is not without critics , it punctuates a reality with which the world must now reckon. Even without climate change, fossil fuels are a finite resource, and if we want our lease on the planet to be renewed, our energy will have to be renewable.

The first U.S. offshore wind farm opened in 2016 in Rhode Island, and other offshore projects are gaining momentum. Another problem with wind turbines is that they’re a danger for birds and bats, killing hundreds of thousands annually, not as many as from glass collisions and other threats like habitat loss and invasive species, but enough that engineers are working on solutions to make them safer for flying wildlife. Solar: From home rooftops to utility-scale farms, solar power is reshaping energy markets around the world. In the decade from 2007 and 2017 the world's total installed energy capacity from photovoltaic panels increased a whopping 4,300 percent. In addition to solar panels, which convert the sun's light to electricity, concentrating solar power (CSP) plants use mirrors to concentrate the sun's heat, deriving thermal energy instead. China, Japan, and the U.S. are leading the solar transformation, but solar still has a long way to go, accounting for around just two percent of the total electricity generated in the U.S. in 2017. Solar thermal energy is also being used worldwide for hot water, heating, and cooling. Biomass: Biomass energy includes biofuels, such as ethanol and biodiesel, wood, wood waste, biogas from landfills, and municipal solid waste. Like solar power, biomass is a flexible energy source, able to fuel vehicles, heat buildings, and produce electricity. But biomass can raise thorny issues. Critics of corn-based ethanol, for example, say it competes with the food market for corn and supports the same harmful agricultural practices that have led to toxic algae blooms and other environmental hazards. Similarly, debates have erupted over whether it's a good idea to ship wood pellets from U.S. forests over to Europe so that it can be burned for electricity. Meanwhile, scientists and companies are working on ways to more efficiently convert corn stover, wastewater sludge, and other biomass sources into energy, aiming to extract value from material that would otherwise go to waste. Geothermal: Used for thousands of years in some countries for cooking and heating, geothermal energy is derived from Earth’s internal heat. On a large scale, underground reservoirs of steam and hot water can be tapped through wells that can go a two kilometers deep or more to generate electricity. On a smaller scale, some buildings have geothermal heat pumps that use temperature differences several meters below ground for heating and cooling. Unlike solar and wind energy, geothermal energy is always available, but it has side effects that need to be managed, such as the rotten-egg smell that can accompany released hydrogen sulfide. Ways To Boost Renewable Energy Cities, states, and federal governments around the world are instituting policies aimed at increasing renewable energy. At least 29 U.S. states have set renewable portfolio standards—policies that mandate a certain percentage of energy from renewable sources. More than 100 cities worldwide now boast receiving at least 70 percent of their energy from renewable sources, and still others are making commitments to reach 100 percent. Other policies that could encourage renewable energy growth include carbon pricing, fuel economy standards, and building efficiency standards. Corporations are making a difference too, purchasing record amounts of renewable power in 2018. Wonder whether your state could ever be powered by 100 percent renewables? No matter where you live, scientist Mark Jacobson believes it's possible. That vision is laid out here , and while his analysis is not without critics , it punctuates a reality with which the world must now reckon. Even without climate change, fossil fuels are a finite resource, and if we want our lease on the planet to be renewed, our energy will have to be renewable.

Fast Facts About Renewable Energy

Principle Energy Uses: Electricity, Heat Forms of Energy: Kinetic, Thermal, Radiant, Chemical

The term “renewable” encompasses a wide diversity of energy resources with varying economics, technologies, end uses, scales, environmental impacts, availability, and depletability. For example, fully “renewable” resources are not depleted by human use, whereas “semi-renewable” resources must be properly managed to ensure long-term availability. The most renewable type of energy is energy efficiency, which reduces overall consumption while providing the same energy service. Most renewable energy resources have significantly lower environmental and climate impacts than their fossil fuel counterparts.

The data in these Fast Facts do not reflect two important renewable energy resources: traditional biomass, which is widespread but difficult to measure; and energy efficiency, a critical strategy for reducing energy consumption while maintaining the same energy services and quality of life.

This Is the Future: Essay on Renewable Energy

Today the world population depends on nonrenewable energy resources. With the constantly growing demand for energy, natural gas, coal, and oil get used up and cannot replenish themselves. 

Aside from limited supply, heavy reliance on fossil fuels causes planetary-scale damage. Sea levels are rising. Heat-trapping carbon dioxide increased the warming effect by 45% from 1990 to 2019. The only way to tackle the crisis is to start the transition to renewable energy now. 

What is renewable energy? It is energy that comes from replenishable natural resources like sunlight, wind, thermal energy, moving water, and organic materials. Renewable resources do not run out. They are cost-efficient and renew faster than they are consumed. How does renewable energy save money? It creates new jobs, supports economic growth, and decreases inequitable fossil fuel subsidies. 

At the current rates of production, some fossil fuels will not even last another century. This is why the future depends on reliable and eco-friendly resources. This renewable energy essay examines the types and benefits of renewable energy and its role in creating a sustainable future.

Top 5 Types of Renewable Energy: The Apollo Alliance Rankings

There are many natural resources that can provide people with clean energy. To make a list of the five most booming types of renewable energy on the market today, this energy essay uses data gathered by the Apollo Alliance. It is a project that aims to revolutionize the energy sector of the US with a focus on clean energy. 

The Apollo Alliance unites businesses, community leaders, and environmental experts to support the transition to more sustainable and efficient living. Their expert opinion helped to compile information about the most common and cost-competitive sources of renewable energy. However, if you want to get some more in-depth research, you can entrust it to an essay writer . Here’s a quick overview of renewable energy resources that have a huge potential to substitute fossil fuels. 

Solar Renewable Energy

The most abundant and practically endless resource is solar energy. It can be turned into electricity by photovoltaic systems that convert radiant energy captured from sunlight. Solar farms could generate enough energy for thousands of homes.

An endless supply is the main benefit of solar energy. The rate at which the Earth receives it is 10,000 times greater than people can consume it, as a paper writer points out based on their analysis of research findings. It can substitute fossil fuels and deliver people electricity, hot water, cooling, heat, etc. 

The upfront investment in solar systems is rather expensive. This is one of the primary limitations that prevent businesses and households from switching to this energy source at once. However, the conclusion of solar energy is still favorable. In the long run, it can significantly decrease energy costs. Besides, solar panels are gradually becoming more affordable to manufacture and adopt, even at an individual level. 

Wind Renewable Energy

Another clean energy source is wind. Wind farms use the kinetic energy of wind flow to convert it into electricity. The Appolo Alliance notes that, unlike solar farms, they can’t be placed in any location. To stay cost-competitive, wind farms should operate in windy areas. Although not all countries have the right conditions to use them on a large scale, wind farms might be introduced for some energy diversity. The technical potential for it is still tremendous. 

Wind energy is clean and safe for the environment. It does not pollute the atmosphere with any harmful products compared to nonrenewable energy resources. 

The investment in wind energy is also economically wise. If you examine the cost of this energy resource in an essay on renewable resources, you’ll see that wind farms can deliver electricity at a price lower than nonrenewable resources. Besides, since wind isn’t limited, its cost won’t be influenced by the imbalance of supply and demand.

Geothermal Renewable Energy

Natural renewable resources are all around us, even beneath the ground. Geothermal energy can be produced from the thermal energy from the Earth’s interior. Sometimes heat reaches the surface naturally, for example, in the form of geysers. But it can also be used by geothermal power plants. The Earth’s heat gets captured and converted to steam that turns a turbine. As a result, we get geothermal energy.

This source provides a significant energy supply while having low emissions and no significant footprint on land. A factsheet and essay on renewable resources state that geothermal plants will increase electricity production from 17 billion kWh in 2020 to 49.8 billion kWh in 2050.

However, this method is not without limitations. While writing a renewable resources essay, consider that geothermal energy can be accessed only in certain regions. Geological hotspots are off-limits as they are vulnerable to earthquakes. Yet, the quantity of geothermal resources is likely to grow as technology advances. 

Ocean Renewable Energy

The kinetic and thermal energy of the ocean is a robust resource. Ocean power systems rely on:

• Changes in sea level;
• Wave energy;
• Water surface temperatures;
• The energy released from seawater and freshwater mixing.

Ocean energy is more predictable compared to other resources. As estimated by EPRI, it has the potential to produce 2640 TWh/yr. However, an important point to consider in a renewable energy essay is that the kinetic energy of the ocean varies. Yet, since it is ruled by the moon’s gravity, the resource is plentiful and continues to be attractive for the energy industry. 

Wave energy systems are still developing. The Apollo energy corporation explores many prototypes. It is looking for the most reliable and robust solution that can function in the harsh ocean environment. 

Another limitation of ocean renewable energy is that it may cause disruptions to marine life. Although its emissions are minimal, the system requires large equipment to be installed in the ocean. 

Biomass Renewable Energy

Organic materials like wood and charcoal have been used for heating and lighting for centuries. There are a lot more types of biomass: from trees, cereal straws, and grass to processed waste. All of them can produce bioenergy. 

Biomass can be converted into energy through burning or using methane produced during the natural process of decomposition. In an essay on renewable sources of energy, the opponents of the method point out that biomass energy is associated with carbon dioxide emissions. Yet, the amount of released greenhouse gases is much lower compared to nonrenewable energy use. 

While biomass is a reliable source of energy, it is only suitable for limited applications. If used too extensively, it might lead to disruptions in biodiversity, a negative impact on land use, and deforestation. Still, Apollo energy includes biomass resources that become waste and decompose quickly anyway. These are organic materials like sawdust, chips from sawmills, stems, nut shells, etc. 

What Is the Apollo Alliance?

The Apollo Alliance is a coalition of business leaders, environmental organizations, labor unions, and foundations. They all unite their efforts in a single project to harness clean energy in new, innovative ways. 

Why Apollo? Similarly to President John F. Kennedy’s Apollo Project, Apollo energy is a strong visionary initiative. It is a dare, a challenge. The alliance calls for the integrity of science, research, technology, and the public to revolutionize the energy industry.

The project has a profound message. Apollo energy solutions are not only about the environment or energy. They are about building a new economy. The alliance gives hope to building a secure future for Americans. 

What is the mission of the Apollo Alliance? 

• Achieve energy independence with efficient and limitless resources of renewable energy.
• Pioneer innovation in the energy sector.
• Build education campaigns and communication to inspire new perceptions of energy. 
• Create new jobs.
• Reduce dependence on imported fossil fuels. 
• Build healthier and happier communities. 

The transformation of the industry will lead to planet-scale changes. The Apollo energy corporation can respond to the global environmental crisis and prevent climate change. 

Apollo renewable energy also has the potential to become a catalyst for social change. With more affordable energy and new jobs in the industry, people can bridge the inequality divide and build stronger communities. 

Why Renewable Energy Is Important for the Future

Renewable energy resources have an enormous potential to cover people’s energy needs on a global scale. Unlike fossil fuels, they are available in abundance and generate minimal to no emissions. 

The burning of fossil fuels caused a lot of environmental problems—from carbon dioxide emissions to ocean acidification. Research this issue in more detail with academic assistance from essay writer online . You can use it to write an essay on renewable sources of energy to explain the importance of change and its global impact. 

Despite all the damage people caused to the planet, there’s still hope to mitigate further repercussions. Every renewable energy essay adds to the existing body of knowledge we have today and advances research in the field. Here are the key advantages and disadvantages of alternative energy resources people should keep in mind. 

Advantage of Green Energy

The use of renewable energy resources has a number of benefits for the climate, human well-being, and economy:

• Renewable energy resources have little to no greenhouse gas emissions. Even if we take into account the manufacturing and recycling of the technologies involved, their impact on the environment is significantly lower compared to fossil fuels. 
• Renewable energy promotes self-sufficiency and reduces a country’s dependence on foreign fuel. According to a study, a 1% increase in the use of renewable energy increases economic growth by 0.21%. This gives socio-economic stability.
• Due to a lack of supply of fossil fuels and quick depletion of natural resources, prices for nonrenewable energy keep increasing. In contrast, green energy is limitless and can be produced locally. In the long run, this allows decreasing the cost of energy. 
• Unlike fossil fuels, renewable energy doesn’t emit air pollutants. This positively influences health and quality of life. 
• The emergence of green energy plants creates new jobs. Thus, Apollo energy solutions support the growth of local communities. By 2030, the transition to renewable energy is expected to generate 10.3 million new jobs. 
• Renewable energy allows decentralization of the industry. Communities get their independent sources of energy that are more flexible in terms of distribution. 
• Renewable energy supports equality. It has the potential to make energy more affordable to low-income countries and expand access to energy even in remote and less fortunate neighborhoods. 

Disadvantages of Non-Conventional Energy Sources

No technology is perfect. Renewable energy resources have certain drawbacks too: 

• The production of renewable energy depends on weather conditions. For example, wind farms could be effective only in certain locations where the weather conditions allow it. The weather also makes it so that renewable energy cannot be generated around the clock. 
• The initial cost of renewable energy technology is expensive. Both manufacturing and installation require significant investment. This is another disadvantage of renewable resources. It makes them unaffordable to a lot of businesses and unavailable for widespread individual use. In addition, the return on investment might not be immediate.
• Renewable energy technology takes up a lot of space. It may affect life in the communities where these clean energy farms are installed. They may also cause disruptions to wildlife in the areas. 
• One more limitation a renewable resources essay should consider is the current state of technology. While the potential of renewable energy resources is tremendous, the technology is still in its development phase. Therefore, renewable energy might not substitute fossil fuels overnight. There’s a need for more research, investment, and time to transition to renewable energy completely. Yet, some diversity of energy resources should be introduced as soon as possible. 
• Renewable energy resources have limited emissions, but they are not entirely pollution-free. The manufacturing process of equipment is associated with greenhouse gas emissions while, for example, the lifespan of a wind turbine is only 20 years.

Renewable and nonrenewable energy sources

• Global energy use
• Intro to energy resources and consumption
• Nonrenewable energy sources are those that are consumed faster than they can be replaced. Nonrenewable energy sources include nuclear energy as well as fossil fuels such as coal, crude oil, and natural gas. These energy sources have a finite supply, and often emit harmful pollutants into the environment.
• Renewable energy sources are those that are naturally replenished on a relatively short timescale. Renewable energy sources include solar, wind, hydroelectric, and geothermal energy. They also include biomass and hydrogen fuels. These energy sources are sustainable and generate fewer greenhouse gas emissions than fossil fuels.

Three essays on renewable energy and sustainability

1st essay abstract:   

This study investigates the economic rents of the wind energy industry in the U.S. and their economic impacts on local economies, using Benton and White counties in Indiana as study regions. By calibrating a partial equilibrium model using 2007-2010 data of the industry, we find a resource rent of $9.72/MWh. We then use a general equilibrium model with Dutch Disease features to study the optimal tax levied on this rent, and the economic impacts of redistributing the tax revenues back to the county residents. An exhaustive rent tax increases real county personal income by as high as 9.1% and as low as 2%, depending on the county’s features. Applying an incentive compatible resource rent tax rate and redistributing the revenues to the county’s laborers leads to an increase of 3.5% and 16% in their income in White and Benton counties, respectively. We also perform robustness checks by allowing labor mobility between counties to examine the impacts of resource rents on the county economy under endogenous labor growth. 

1st essay data: All data acquired comes from the U.S. Census Bureau, county Quarterly Census of Employment and Wages, the National Renewable Energy Laboratory reports, the Lawrence Berkeley Laboratory, Indeed.com, news articles, and wind developers websites.

2nd essay abstract:   

Using the Regional Energy Deployment System (ReEDS) model, we estimate the deadweight loss imposed by county-level wind power development restrictions in the form of increased electricity costs due to suboptimal siting. This is accomplished by optimizing the power system of the United States' Midcontinent Independent System Operator (MISO) from 2020 to 2050. We perform the optimization with and without land-use constraints arising from simulated potential local ordinances restricting wind power development, and under multiple scenarios reflecting different renewable portfolio standards (RPS). We find that local restrictions on wind power increase the total system cost by 0.15%-0.3% and the wholesale electricity price by 1.8%-2.7%, depending on the RPS scenario. Changes in the generation and installed capacity mixes are more substantial and depend on both the level of county restrictions on wind power, and RPS requirements, thus indicating an interaction between RPS requirements and local wind power restrictions. We also find that plausible restrictions on wind development do not pose major barriers to meeting renewable energy targets in a cost-effective manner.

2nd essay data: All data is embedded inside the Regional Energy Deployment System (ReEDS) model of the National Renewable Energy Laboratory.

3rd essay abstract:   

The USDA promotes adoption of conservation practices beneficial for soil health and environment through agricultural cost-share payment programs such as EQIP or CSP. Although the efficiency of these programs has been evaluated through additionality estimates, which represent the percentage of farmers who would adopt a practice only with payments, the potential complementarities between certain combinations of practices have often been overlooked. Unaccounted for, these complementarities may impact additionality estimates. This paper provides a thorough investigation of additionality estimates of common practices, including no-till, nutrient management and cover crops, accounting for potential complementarities between them. We find no significant differences between traditional additionality estimates and estimates accounted for potential complementarities between the three practices. The results thus indicate that despite agronomic evidence of synergies in co-adopting these three practices, we find no solid indication of adoption complementarity between them in reality.

What is renewable energy?

Renewable energy is energy derived from natural sources that are replenished at a higher rate than they are consumed. Sunlight and wind, for example, are such sources that are constantly being replenished. Renewable energy sources are plentiful and all around us.

Fossil fuels - coal, oil and gas - on the other hand, are non-renewable resources that take hundreds of millions of years to form. Fossil fuels, when burned to produce energy, cause harmful greenhouse gas emissions, such as carbon dioxide.

Generating renewable energy creates far lower emissions than burning fossil fuels. Transitioning from fossil fuels, which currently account for the lion’s share of emissions, to renewable energy is key to addressing the climate crisis.

Renewables are now cheaper in most countries, and generate three times more jobs than fossil fuels.

Here are a few common sources of renewable energy:

SOLAR ENERGY

Solar energy is the most abundant of all energy resources and can even be harnessed in cloudy weather. The rate at which solar energy is intercepted by the Earth is about 10,000 times greater than the rate at which humankind consumes energy.

Solar technologies can deliver heat, cooling, natural lighting, electricity, and fuels for a host of applications. Solar technologies convert sunlight into electrical energy either through photovoltaic panels or through mirrors that concentrate solar radiation.

Although not all countries are equally endowed with solar energy, a significant contribution to the energy mix from direct solar energy is possible for every country.

The cost of manufacturing solar panels has plummeted dramatically in the last decade, making them not only affordable but often the cheapest form of electricity. Solar panels have a lifespan of roughly 30 years , and come in variety of shades depending on the type of material used in manufacturing.

WIND ENERGY

Wind energy harnesses the kinetic energy of moving air by using large wind turbines located on land (onshore) or in sea- or freshwater (offshore). Wind energy has been used for millennia, but onshore and offshore wind energy technologies have evolved over the last few years to maximize the electricity produced - with taller turbines and larger rotor diameters.

Though average wind speeds vary considerably by location, the world’s technical potential for wind energy exceeds global electricity production, and ample potential exists in most regions of the world to enable significant wind energy deployment.

Many parts of the world have strong wind speeds, but the best locations for generating wind power are sometimes remote ones. Offshore wind power offers t remendous potential .

GEOTHERMAL ENERGY

Geothermal energy utilizes the accessible thermal energy from the Earth’s interior. Heat is extracted from geothermal reservoirs using wells or other means.

Reservoirs that are naturally sufficiently hot and permeable are called hydrothermal reservoirs, whereas reservoirs that are sufficiently hot but that are improved with hydraulic stimulation are called enhanced geothermal systems.

Once at the surface, fluids of various temperatures can be used to generate electricity. The technology for electricity generation from hydrothermal reservoirs is mature and reliable, and has been operating for more than 100 years .

Hydropower harnesses the energy of water moving from higher to lower elevations. It can be generated from reservoirs and rivers. Reservoir hydropower plants rely on stored water in a reservoir, while run-of-river hydropower plants harness energy from the available flow of the river.

Hydropower reservoirs often have multiple uses - providing drinking water, water for irrigation, flood and drought control, navigation services, as well as energy supply.

Hydropower currently is the largest source of renewable energy in the electricity sector. It relies on generally stable rainfall patterns, and can be negatively impacted by climate-induced droughts or changes to ecosystems which impact rainfall patterns.

The infrastructure needed to create hydropower can also impact on ecosystems in adverse ways. For this reason, many consider small-scale hydro a more environmentally-friendly option , and especially suitable for communities in remote locations.

OCEAN ENERGY

Ocean energy derives from technologies that use the kinetic and thermal energy of seawater - waves or currents for instance -  to produce electricity or heat.

Ocean energy systems are still at an early stage of development, with a number of prototype wave and tidal current devices being explored. The theoretical potential for ocean energy easily exceeds present human energy requirements.

Bioenergy is produced from a variety of organic materials, called biomass, such as wood, charcoal, dung and other manures for heat and power production, and agricultural crops for liquid biofuels. Most biomass is used in rural areas for cooking, lighting and space heating, generally by poorer populations in developing countries.

Modern biomass systems include dedicated crops or trees, residues from agriculture and forestry, and various organic waste streams.

Energy created by burning biomass creates greenhouse gas emissions, but at lower levels than burning fossil fuels like coal, oil or gas. However, bioenergy should only be used in limited applications, given potential negative environmental impacts related to large-scale increases in forest and bioenergy plantations, and resulting deforestation and land-use change.

Given the key role renewable energy plays in averting the impending climate crisis, assessments of the sustainability of renewable energy systems (RESs) are often heavily skewed towards their environmental benefits, such as reductions in carbon emissions. However, RES projects also have the potential to actively harm progress towards other aspects of sustainability, particularly when hidden within the energy generation process. Given the growing understanding of the ’dark side‘ of renewables, we must ask the question: Is renewable energy sustainable? To gain a better understanding of this issue, we analyzed the degree of alignment of seven aspects of the renewable energy production process with the Sustainable Development Goals (SDGs) and their targets for six renewable energy types categorizing the relationships as either enablers or inhibitors. This information makes it possible for decision- and policy- makers to move beyond carbon tunnel vision to consider the wider impacts of RESs on sustainable development.

Introduction.

Achieving net zero carbon emissions is the holy grail of climate change policies, with the transition to renewable energy sources often considered the hero in this quest. While the need to transition to renewables is unquestioned, the myopic pursuit of achieving net zero emissions has resulted in ’carbon tunnel vision 1 ‘ (i.e., a focus on the ability of renewables to reduce carbon emissions at the expense of the consideration of wider impacts), as a consequence of which the broader environmental, social and economic impacts (both positive and negative) of the transition are generally ignored. This means that we are now in treacherous territory, as the switch to renewables to address the current climate crisis could unwittingly create a cascade of other problems for future generations. Consequently, there is a need to better understand the potential positive and negative impacts of renewable energy systems so that we can ensure that the transition to renewables can occur in a sustainable manner.

In order to meet this need, we present a high-level overview of the potential enabling (positive) and inhibiting (negative) relationships between renewable energy systems (RESs) and the United Nation’s Sustainable Development Goals (SDGs) 2 , based on a review of the literature (see Fig. 1 caption for details and definitions). We pay particular attention to how these relationships vary for different types of renewable energy systems (biomass, hydropower, solar, geothermal, wind, wave & tidal 3 ) and how the various aspects of the renewable energy production process affect the environmental, social and economic elements of sustainability as characterized by the SDGs 4 . This enables us to obtain a better understanding of (i) the degree of sustainability of renewable energy systems, (ii) the impacts of adopting carbon tunnel vision, and (iii) what we need to do to broaden our vision to achieve more sustainable outcomes.

SDGs are grouped according to the categories of social, environmental and economic factors based on the Wedding Cake Model 52 . Specific targets recognized in the 2030 Agenda for Sustainable Development 2 (excluding government implementation targets) are grouped under each associated SDG and ordered clockwise. As was done in previous papers 53 , connections shown in green in ( a ) indicate a renewable energy project can potentially enable achieving a SDG target (this is equivalent to the concepts of reinforcing 54 providing synergies 55 and accomplishing 53 SDG targets). Connections shown in orange in ( b ) indicate a renewable energy project can potentially inhibit progress towards a SDG target (this is equivalent to the concepts of undermining 54 , providing trade-offs 55 and inhibiting 53 progress). Full results of the assessment for each target can be found in the Supplementary Information . Note that SDGs 4, 5, and 10 are excluded from this study since no direct relationships with quantitative indicators could be identified in literature. Given that SDG 16 and SDG 17 are at the heart of the SDG synergies, serving as fundamental interconnections to all other goals 56 , they are also excluded from our study. This is an original figure that was produced by the authors using AutoCAD.

How sustainable are renewable energy systems?

While the transition from fossil fuels to renewable energy sources is strongly associated with positive impacts on climate action (SDG 13), there can also be a number of inhibiting relationships with this SDG (Fig. 1b ). Such cases primarily involve the flaring (i.e., burning) of greenhouse gas, leading to emissions during certain types of renewable energy production (e.g., the generation of carbon emissions 5 and the leakage of methane during transportation and storage 6 for biomass production; the release of greenhouse gases when drilling for geothermal energy 7 ; and disturbing deep underwater sediments (e.g., particles settled at the bottom of water bodies) during the operation of hydropower plants 8 ). More importantly, renewable energy systems can also have potential enabling and inhibiting relationships with a number of other SDGs within the environmental category, including life below water (SDG 14), life on land (SDG 15) and clean water and sanitation (SDG 6).

Impacts related to life below water (SDG 14) are primarily associated with the production of wave and tidal power, with potential enabling relationships including enhancing the protection of coastal areas, as the installation of barriers and turbines can contribute to nutrient accumulation for coral protection 1 , 9 , and potential inhibiting relationships including threats to marine life, such as the harming of bird populations by offshore wind farms 10 , 11 . For life on land (SDG 15), potential enabling relationships include the repurposing of natural land, such as establishing wind and solar farms on degraded land 12 , whereas potential inhibiting relationships include the degradation of land quality when biomass contributes to soil erosion and degradation through the use of energy crops and the collection of crop residuals 13 . Regarding clean water and sanitation (SDG 6), potential enabling relationships include improved water-use efficiency 14 , 15 and potential inhibiting relationships relate to the reduced availability of drinking water, such as the contamination of underground aquifers from geothermal exploration, the tainting of potable surface water as a result of the leakage of biomass feedstock, and the allocation of significant water resources for hydropower infrastucture 16 , 17 .

In addition to their impact on the production of affordable and clean energy (SDG 7), renewable energy systems can also affect a range of other SDGs in the social category, including no poverty (SDG 1), zero hunger (SDG 2), good health and well-being (SDG 3), and sustainable cities and communities (SDG 11). However, in contrast to SDG 7, where renewable energy systems solely act as enablers, for these other SDGs, they can act as both inhibitors and enablers. For example, in relation to no poverty (SDG 1), potential inhibiting relationships stem from the intermittency of wind and solar energy sources 18 , while enablers could relate to the improvement of living standards through the provision of usable energy 19 . As far as zero hunger (SDG 2) is concerned, potential inhibiting relationships include the reduction of land availability for food production due to renewable energy installations 13 , with potential enabling relationships pertaining to the integration of RESs into agricultural farms (e.g., shading crops with solar panels) 20 , which has the potential to enhance resilience and productivity within the agriculture sector. Regarding good health and well-being (SDG 3), inhibiting relationships could include illnesses caused by harmful chemicals inadvertently released into the air and water, such as hazardous wastewater from geothermal energy production 21 , while potential enabling relationships include the prevention of respiratory infections and disease related to carbon pollution 22 . Finally, in relation to sustainable cities and communities (SDG 11), inhibiting relationships could arise from the environmental impact of RESs on modern cities, such as foul odours from biomass conversion, alterations in the microclimate caused by wind turbines and hydropower dams 23 and light pollution from solar panels 24 . In contrast, potential enabling relationships might relate to reduced damage to heritage land compared with that caused by the exploitation of conventional energy sources 12 , 25 .

RESs also have potential enabling and inhibiting relationships with various economic SDGs, including decent work and economic growth (SDG 8), industry, innovation and infrastructure (SDG 9) and responsible consumption and production (SDG 12). In relation to decent work (SDG 8), potential enabling relationships include the provision of decent work opportunities within emerging RES projects 26 , while inhibiting relationships relate to the likely reduction in job availability in the fossil fuel industry 27 , 28 . As far as industry, innovation and infrastructure (SDG 9) is concerned, potential enabling relationships include decreased carbon intensity through soil carbon sequestration and CO 2 recycling, while inhibiting relationships could relate to bioenergy and hydropower, for which energy sources require transportation, potentially increasing carbon intensity 29 . With regard to responsible consumption and production (SDG 12), enabling relationships could include improved management of natural resources, where waste and recyclable materials as waste can be utilized as a bioenergy source 30 , whereas potential inhibiting relationships include encroachment on natural resources and the generation of hazardous waste 15 , 21 .

What is the impact of carbon tunnel vision?

In order to obtain a more holistic and comprehensive understanding of the impact carbon tunnel vision has on broader aspects of sustainability, the relationships in Fig. 1 are decomposed by renewable energy type and aspect of the energy production process (Fig. 2 ). The different types of renewables considered include biomass, hydropower, solar, geothermal, wind, and wave & tidal, as these are the most commonly used sources, given current technologies. The aspects of the renewable energy production process considered include source selection, conversion and associated operational requirements, re-use, waste production, storage and transmission & distribution (Fig. 3 ), as these can differ for different types of RESs and include lesser-known elements of the renewable energy supply chain that often receive diminished attention. In the absence of this more nuanced understanding, it is easy to underestimate both the negative and positive sustainability impacts of renewable energy production on SDGs, making it more difficult to escape the currently adopted carbon tunnel vision, as detailed in subsequent sections.

SDG targets are presented by a single value and are divided into three principal spheres—social, economic, and environmental—which are depicted on the vertical axis. The horizontal axis categorizes the six renewable energy types. Within each type, the seven aspects of the energy production process (see Fig. 3 ) are presented in two rows, where connections are shown between a SDG, renewable energy type and aspect of the renewable energy production process. A green index color represents ‘enablers,’ while the orange index color signifies ‘inhibitors’. A lack of highlighting indicates the absence of identified evidence from literature, although it is important to note that this does not necessarily imply the absence of a relationship per se, just that this was outside of the boundary of consideration used here (more details are provided in the Supplementary Information ). This is an original figure that was produced by the authors using the Microsoft Excel Spreadsheet Software.

These aspects are presented within the context of the operational input-process-output concept. Source selection is considered as the first aspect, noting that the storing of potential energy is where impacts emerge—there are no direct impacts from renewable energy types with kinetic energy sources. The process of converting the source into energy can influence SDGs, both through the conversion process itself (i.e., plant location) and the associated operational requirements. After the completion of the renewable energy production process step and before the generation of the output, by-products can either be re-used elsewhere or go to waste. The production outputs can be divided into two parts: storage for local use and operational support, and transmission and distribution for grid connection or delivery. This is an original figure that was produced by the authors using Microsoft PowerPoint.

Underestimation of negative sustainability impacts

As can be seen from Fig. 2 , one of the major impacts of adopting carbon tunnel vision is that, by solely focusing on climate action (SDG 13) and the production of affordable and clean energy (SDG 7), the vast majority of inhibiting relationships between renewable energy production and the SDGs (i.e., the orange cells in Fig. 2 ) are ignored, which is likely to result in a distorted view of the sustainability of RESs. However, it should be noted that the focus on net zero emissions might not be the only reason for the lack of consideration of the potentially negative impacts of renewables on sustainability. This is because inhibiting relationships are primarily associated with the less well-known and understood aspects of the renewable energy production process (such as conversion and associated operational requirements, re-use and the generation of waste), rather than the more well-known and better understood processes (such as those associated with source selection, storage and transmission & distribution).

These potentially negative impacts affect a range of SDGs (Fig. 2 ). For example, operational requirements of renewable energy projects can have a negative impact on SDG 2 (zero hunger) because the development of RESs competes with the agricultural sector for natural resources such as water and minerals, along with land use 15 . This is particularly the case for bioenergy, as energy farming may occupy agriculturally viable land 13 , 16 . The conversion process and storage of energy can have a negative impact on SDG 11 (sustainable cities and communities), as renewable energy plants and storage facilities can unintentionally encroach on cultural and heritage lands, especially sacred lands of First Nations people (i.e., for indigenous peoples who are the earliest known inhabitants of an area), posing a potential infringement on indigenous rights 25 , 31 . Similarly, the conversion process can have a negative impact on SDG 15 (life on land), as renewable energy facilities are likely to cause damage to the biodiversity of surrounding areas (i.e. natural wildlife) 32 , 33 .

In most cases, the inhibiting relationships between the aspects of the renewable energy production process and the SDGs are specific to a particular renewable energy type. For example, the storage component of the source selection step (Fig. 3 ) can negatively impact SDG 12 (responsible consumption and production) in the case of biomass and hydropower. For the former, this is because the feedstock required for bioenergy production necessitates the use of storage facilities, like warehouses or hubs for biomass storage and pre-processing 34 , thereby increasing material resource use and land occupation. For the latter, this is because the storage of water required for hydropower production necessitates the use of dams or reservoirs for storage and collection, potentially altering and using surrounding natural resources 21 , 35 . In contrast, this is not the case for solar, wind and wave & tidal energy (Fig. 3 ).

Similarly, the conversion process (Fig. 3 ) can result in an inhibitive relationship with SDG 14 (life below water) for hydropower, wind and wave & tidal. For hydropower, this is due to the potential to artificially alter aquatic ecosystems and redirect the flow of rivers 21 , 35 . For wind power, this is because of the potential contribution of offshore wind farms to biofouling and the generation of underwater noise 36 , whereas for wave & tidal power, tidal barriers can modify the flow of water and wave patterns 1 , 9 . However, the same does not apply to biomass, solar, or geothermal. This demonstrates that particular care must be taken to understand the inhibiting factors for different renewable energy types in order to obtain a comprehensive understanding of their impact on sustainability.

Underestimation of positive sustainability impacts

Figure 2 also highlights that another significant impact of adopting carbon tunnel vision by only considering SDG 13 (climate action) is the lack of consideration of a large number of the other positive SDG impacts of renewable energy production, which is also likely to result in a distorted assessment of the sustainability of RESs. As can be seen in Fig. 2 , all types of RESs exhibit potentially enabling relationships with all of the social (i.e., SDGs 1 - 3, 7, 11) and economic (i.e., SDGs 8, 9, 12) aspects of sustainability. In addition, the components of the renewable energy production process where these occur are generally the same. For example, for SDG 1 (Target 1.5: build resilience to environmental, economic and social disasters), there is a potentially enabling relationship with source selection, transmission & distribution, and storage. This is because renewable energy can directly assist individuals in impoverished conditions by providing them access to electricity, thereby reducing their risk of suffering from local disasters 37 . For SDG 2 (zero hunger), there is a potentially enabling relationship with transmission and storage, attributable to the efficiency and advanced integrated farming techniques that can be enhanced when food production is paired with RESs 38 . Similarly, for SDG 3 (good health and well-being), there is a potential enabling relationship from using renewable energy (conversion, transmission & distribution and storage), as this can reduce the risk of cardiovascular diseases caused by air pollution (PM2.5, PM10) 22 , as well as chronic respiratory disease resulting from the burning of traditional energy sources like coal and fuel 39 . For SDG 15 (life on land), there is a potentially enabling relationship with the conversion process, as renewable energy plants do not require further deforestation for installation and can repurpose degraded land, such as deserts or areas suffering from soil erosion 12 .

However, some of these enabling relationships only apply to specific combinations of renewable energy type and aspects of the energy production process. For example, biomass and hydropower can have a positive impact on SDG 6 (clean water and sanitation) and SDG 11 (sustainable cities and communities) because they are able to use municipal wastewater as one of their energy sources 30 , 40 , thereby purifying water and reusing it as a product or by-product 41 . Additionally, bioenergy, geothermal energy and hydropower can have a positive impact on SDG 12 (responsible consumption and production), as bioenergy production can result in the generation of fertilizer as a by-product, thereby reducing material usage and promoting recycling 42 , 43 , hydropower can supply clean water to downstream areas 44 , and geothermal energy can provide heating/irrigation water for direct applications such as greenhouse farming 45 .

How do we broaden our vision?

As highlighted in the previous sections, while renewable energy sources are a strong enabler of climate action, as well as a number of other SDGs, they can also have a range of negative social, environmental and economic impacts. Consequently, there are several significant conclusions to draw that affect how we should think about climate policy:

Ignoring the potential negative impacts of RESs in the singular pursuit of net zero carbon emissions has the potential to result in disastrous consequences and the perverse outcome that solutions intended to increase the sustainability of humankind actually have the opposite effect. We need to heed the lessons of history to avoid another “hole in the ozone layer” by trying to “fix” a specific issue without considering all potential consequences in an integrated fashion. For policy makers, this can be combated by more cross-agency participation in the management of renewable energy zones and planning, so that trade-offs of a proposed solution can be more apparent.

RESs have enabling relationships with a much broader range of SDGs, not just climate action (SDG 13) and affordable and clean energy (SDG 7), which, if ignored, can significantly underestimate their positive impact on sustainability. This includes the potential to improve the living conditions of communities through the creation of employment opportunities, improved access to resources or reduced health risks, as well as through supporting the biodiversity of the surrounding environment. While there is mounting political pressure to deliver on decarbonization targets, these synergies are at risk of not being capitalized on, and the multiple benefits of implementing renewable energy projects need to be framed in a more holistic way.

By identifying the potential inhibiting and enabling relationships between RESs and the SDGs, this paper provides a blueprint for sustainability assessments that will enable us to broaden our vision beyond considering the impacts of renewables on net-zero emissions to considering the full range of sustainability impacts, allowing for more structured conversations to occur within project management and policy development. This includes an awareness of all potential negative and positive impacts of different types of renewables on different elements of sustainability, as well as for which aspect(s) of the renewable energy production process they occur. Such awareness is especially important for the aspects for which management decisions determine whether sustainability impacts are enabling or inhibiting. For example, the conversion process can have both positive and negative impacts on SDG 11 (sustainable cities and communities), depending on how the government and local society manage their strategy for the preservation, protection, and conservation of all cultural and natural heritage. Similarly, operation and transmission & distribution can have both positive and negative impacts on SDG 8 (decent work and economic growth), depending on the degree to which renewable energy sources are able to promote GDP growth 46 and create more job opportunities with fair pay 47 . To further the ability for renewable energy projects to be more sustainable, future work on this topic should focus on ways to quantity the impact renewable energy projects can have on the SDGs identified, to allow for more direct comparisons for decision makers 48 , 49 , and policy makers alike 50 , 51 .

The enabling and inhibiting relationships between renewable energy sources and the SDGs identified in this paper provide a step toward the information needed to develop climate policy and associated action plans that ensure that we can achieve net zero emissions by implementing RESs in a sustainable manner. This will enable us to address the climate crisis in a manner that avoids mistakes of the past and creates a positive future for our planet.

The growing material for optoelectronics, thermoelectric and renewable energy applications includes Ge 1− x Bi x Te ( x  = 12% and 24%). So, by using DFT and WEIN2k code, we calculated the electronic, optical and also thermoelectric properties of Ge 1− x Bi x Te ( x  = 12% and 24%). In GGA and GGA + SO, the band structures are studied which shows metallic nature. The entire geometric optimization process was carried out based on the cell parameters. Obtained results suggested that Ge 1− x Bi x Te ( x  = 12% and 24%) exhibits a predominantly metallic behavior. From through study of electronic charge density, we verified that the nature of examined material is primarily metallic. Bottom of the conduction and top of valence bands are due to Bi, Ge- p and Ti- p / s orbitals with minimal contributions of Bi-s orbitals states. We estimated optical parameters like optical conductivity, absorption coefficient, dielectric function, reflectivity coefficient, loss function, and refractive index for the polarized incident radiation. Finally, we calculated thermoelectric attributes like seebeck coefficient and others with the use of Boltzmann transport theory. The calculated optical and thermoelectric properties suggested that the doped system could be a potential material for optoelectronic applications with high absorption coefficient values in visible and ultraviolet region. This research provides valuable insights into the potential use of Ge 1-x Bi x Te for both x  = 12% and 24% by using GGA + SO as promising candidate for renewable energy applications.

At a Dinner, Trump Assailed Climate Rules and Asked $1 Billion From Big Oil

At a private meeting at Mar-a-Lago, the former president said fossil fuel companies should donate to help him beat President Biden.

By Lisa Friedman ,  Coral Davenport ,  Jonathan Swan and Maggie Haberman

Former President Donald J. Trump told a group of oil executives and lobbyists gathered at a dinner at his Mar-a-Lago resort last month that they should donate $1 billion to his presidential campaign because, if elected, he would roll back environmental rules that he said hampered their industry, according to two people who were there.

About 20 people attended an April 11 event billed as an “energy round table” at Mr. Trump’s private club, according to those people, who asked not to be identified in order to discuss the private event. Attendees included executives from ExxonMobil, EQT Corporation and the American Petroleum Institute, which lobbies for the oil industry.

The event was organized by the oil billionaire Harold Hamm, who has for years helped to shape Republican energy policies. It was first reported by The Washington Post.

Mr. Trump has publicly railed for months against President Biden’s energy and environmental agenda, as Mr. Biden has raced to restore and strengthen dozens of climate and conservation rules that Mr. Trump had weakened or erased while in office. In particular, Mr. Trump has promised to eliminate Mr. Biden’s new climate rules intended to accelerate the nation’s transition to electric vehicles, and to push a “drill, baby, drill” agenda aimed at opening up more public lands to oil and gas exploration.

Mr. Biden has called climate change an existential threat and has moved to cut the pollution that is dangerously heating the planet and supercharging storms, heat waves and drought.

Over a dinner of chopped steak, Mr. Trump repeated his public promises to delete Mr. Biden’s pollution controls, telling the attendees that they should donate heavily to help him beat Mr. Biden because his policies would help their industries.

“That has been his pitch to everybody,” said Michael McKenna, who worked in the Trump White House but did not attend the event in Florida.

Mr. McKenna said the former president’s appeal to the fossil fuel industry could be summed up as: “Look, you want me to win. You might not even like me, but your other choice is four more years of these guys,” referring to the Biden administration. He added, “The uniform sentiment of guys in the business community is ‘We don’t want four more years of Team Biden.’”

Karoline Leavitt, a spokeswoman for the Trump campaign, did not address the specifics of what Mr. Trump was described as saying at the dinner. In a statement, she attacked President Biden as controlled “by environmental extremists who are trying to implement the most radical energy agenda in history and force Americans to purchase electric vehicles they can’t afford,” and that Mr. Trump is “supported by people who share his vision of American energy dominance to protect our national security and bring down the cost of living for all Americans.”

Mr. Biden’s presidential campaign on Thursday accused Mr. Trump of “straight up selling out working families for campaign donations from oil barons.”

Mr. Biden has frustrated the fossil fuel industry by pursuing the most ambitious climate agenda in the nation’s history. He has signed a sweeping law that pumps $370 billion into incentives for clean energy and electric vehicles and has enacted a suite of tough regulations designed to sharply reduce emissions from the burning of oil, gas and coal.

This year, the Biden administration paused the permitting process for new facilities that export liquefied natural gas in order to study their impact on climate change, the economy and national security.

But the fossil fuel industry has also enjoyed record profits under the Biden administration. Last year, the United States produced record amounts of oil . And even with the pause in new permits for gas export terminals, the United States is the world’s leading exporter of natural gas and is still on track to nearly double its export capacity by 2027 because of projects already permitted and under construction.

Mr. Biden has also approved several oil and gas projects sought by the fossil fuel industry.

He has authorized an enormous $8 billion oil development in Alaska known as the Willow project. He also granted a crucial permit for the Mountain Valley Pipeline, a project championed by Senator Joe Manchin III, a West Virginia Democrat, despite opposition from climate experts and environmental groups. Last month, undeterred by opposition from climate activists, the Biden administration also gave approval for an oil export project in Texas known as the Sea Port Oil Terminal.

Some oil and gas executives have said that they would prefer some of Mr. Biden’s regulations to remain, such as a rule requiring companies to detect and stop methane leaks from oil and gas wells. They said they wanted consistency rather than an endless pattern of regulatory whiplash in which rules are enacted by one administration, repealed by the next and restored by the one after that.

Many, however, have attacked Mr. Biden’s policies, and the industry has contributed heavily to Mr. Trump’s presidential campaign.

Although attendees were told that Mr. Trump’s event was an energy round table, waiting on the chairs of executives and lobbyists at Mar-a-Lago were printouts of PowerPoint slides about migrants at the southern border.

Part of the meeting dwelled on migration, and Mr. Trump declared he wanted separate divisions of Ultimate Fighting Championship fighters: one designated for immigrants who came across the border illegally, and the other for “Americans.”

The room was filled predominantly with oil and gas executives, including Mike Sabel, the chief executive and founder of Venture Global LNG; Toby Rice, the president and chief executive of EQT Corporation; Jack Fusco, the chief executive of Cheniere Energy; and Nick Dell’Osso, the president of Chesapeake Energy.

Also in the room were Doug Burgum, the governor of North Dakota and a former Republican presidential candidate who has been acting as Mr. Trump’s point man on energy issues; and Mr. Hamm, the billionaire executive chairman of Continental Resources, which is among the biggest oil and gas drilling companies in Oklahoma and North Dakota.

Accompanied by Susie Wiles, his top political adviser; Taylor Budowich, a former aide; and Meredith O’Rourke, a fund-raiser, Mr. Trump asked the executives to detail their concerns on energy issues, according to the two attendees.

The American Petroleum Institute, the nation’s top fossil fuel industry group, is running an eight-figure national advertising campaign to promote fossil fuels and “dismantle policy threats,” Mike Sommers, the chief executive of the trade group, has said. Separately, the American Fuel & Petrochemical Manufacturers, which represents petroleum refiners, has started to buy ads in nine battleground states urging Americans to fight Mr. Biden’s regulation on tailpipe emissions.

And states with Republican attorneys general have filed legal challenges against most if not all of Mr. Biden’s regulations, including a suit announced on Thursday by 27 states arguing that the administration overstepped its authority in cracking down on smokestack pollution from power plants.

But Mr. Trump told executives they were not fighting hard enough. He also went on a rant about windmills, the attendees said. Mr. Trump has falsely claimed that wind turbines cause cancer and that offshore wind farms are “driving whales crazy .”

Mr. Trump did not request money in exchange for killing Mr. Biden’s climate regulations, the two people in the room maintained. Rather, the former president told executives that he was determined to squash what he considered anti-business policies, and that the oil industry should therefore want him to win and should raise $1 billion to ensure his success.

He told the executives that the amount of money they would save in taxes and legal expenses after he repealed regulations would more than cover a billion dollar contribution, the people said.

Mr. Hamm has had Mr. Trump’s ear on energy issues dating back to the former president’s 2016 campaign and pushed him to appoint Scott Pruitt to run the Environmental Protection Agency, where Mr. Pruitt denied the established science of climate change and unraveled environmental protections.

After Mr. Trump lost the 2020 election, Mr. Hamm briefly supported some of the former president’s rivals, including Gov. Ron DeSantis of Florida and former United Nations Ambassador Nikki Haley. But the oil tycoon appeared to have had a change of heart. Mr. Hamm donated $3,300 to Mr. Trump’s campaign last year, the maximum allowed for a primary contribution, and another $3,300 in March, according to campaign filings.

Mr. Hamm did not immediately respond to a request for comment. Mr. McKenna said Mr. Hamm continued to play an outsize role in Mr. Trump’s energy policy. “If Harold has an idea, the rest of us have to chase it around,” he said. “Harold Hamm wants that L.N.G. pause gone, he wants the California waiver and the tailpipe rule gone.”

California has for decades received waivers under the Clean Air Act that authorize it to set environmental rules that are tougher than federal regulations. To do business in California, automakers and other industries must comply with its rules. Mr. Trump has promised to revoke California’s waivers.

Trump’s search for a running mate is still in its early stages, but he is said to be leaning toward more experienced options  who can help the ticket without seizing his precious spotlight.

Biden commemorated the 70th anniversary of Brown v. Board of Education, meeting with plaintiffs and their families at the White House as he tries to shore up support among Black Americans , who helped deliver him the White House in 2020.

As Trump’s criminal trial winds down, a center-left group is trying to goad him into testifying through an ad . Trump instead is visiting Minnesota, where his campaign says it can broaden the electoral battlefield with a play for the state  that always disappoints Republicans.

A Remarkable Pivot:  Larry Hogan, the former two-term Republican governor of Maryland who won his party’s nomination for the state’s open Senate seat, said that he supports legislation to codify abortion rights  in federal law.

Gavin Newsom Accuses Trump:  The California governor, speaking at the Vatican, used sharp language to describe the former president’s  appeal to fossil fuel executives for campaign donations, calling it “open corruption.”

How Rich Candidates Burned Cash:  It is a time-honored tradition in U.S. politics: wealthy people burning through their fortunes  to ultimately lose an election.

Montana’s Senate Race:  Republicans are trying to paint Senator Jon Tester as a Washington sellout, while their own candidate, Tim Sheehy, faces scrutiny over his credibility and how he sustained a gunshot wound. It all comes down to the question of trust.
