What You'll Learn
The US is the biggest carbon polluter in history
The United States has contributed more than any other country to the atmospheric carbon dioxide that is heating the planet. This is largely due to its long-time dependence on fossil fuels, particularly coal, for electricity. Coal supplies just under half of America's electricity and is the dirtiest of all fuels, having the highest carbon content of any fossil fuel per unit of energy. America's coal-fired power plants emitted more than 80 percent of CO2 pollution from U.S. power plants in 2007 and 36 percent of the total U.S. CO2 pollution. These power plants also emit disproportionate amounts of smog- and soot-forming pollutants, toxic mercury, and other toxic air pollutants.
The United States, with its love of big cars, big houses, and blasting air conditioners, has a large carbon footprint. The typical American burns roughly twice as much carbon as the average person in Europe or Japan, and 10 times as much as the average person in India. The US is also home to many super polluters, facilities that emit millions of pounds of toxic air pollution and greenhouse gases. These super polluters are often coal-fired power plants, such as those found in Indiana, Texas, and Georgia.
While the US is no longer the world's largest emitter of greenhouse gases, having been surpassed by China about a decade ago, it is still responsible for almost a third of the excess carbon dioxide in the atmosphere. This is due to its long history of burning fossil fuels, particularly coal, which has had a cumulative effect on the environment. The US has also been criticized for its lack of leadership in finding solutions to climate change, with the Trump administration abandoning emissions targets and pledges to help poor countries battle global warming.
The US's heavy reliance on fossil fuels not only contributes to global warming but also poses risks to its economy and national security. The country's dependence on imports from unfriendly parts of the world makes it vulnerable to supply disruptions and geopolitical tensions. Additionally, the environmental impacts of fossil fuel use, such as air and water pollution, can have significant economic costs.
To address these issues, the US needs to transition to clean and renewable energy sources, such as wind and solar power. While the production of renewable energy is growing in the US, it still accounts for a small portion of the country's electricity mix. By investing in clean energy infrastructure and retiring old, inefficient, and dirty power plants, the US can reduce its carbon emissions and mitigate the impacts of climate change.

Coal is the biggest culprit
The United States is the biggest carbon polluter in history, with its high consumption of big cars, large houses, and air conditioners. The country has contributed more than any other to the atmospheric carbon dioxide that is warming the planet. Coal is the biggest culprit, supplying just under half of America's electricity, more than any other source, and is the dirtiest of all fuels. Coal has the highest carbon content of any fossil fuel per unit of energy, meaning that burning coal for electricity produces more carbon per kilowatt-hour generated than burning oil or natural gas.
America's fleet of coal-fired power plants emitted more than 80 percent of CO2 pollution from U.S. power plants in 2007 and 36 percent of the total U.S. CO2 pollution. These plants also emit disproportionate amounts of smog- and soot-forming pollutants, toxic mercury, and other toxic air pollutants. Coal-fired power plants are particularly concentrated in Indiana, with nearly seven plants within 30 miles of Evansville, Indiana. These plants pump out millions of pounds of toxic air pollution and are responsible for greenhouse gas emissions that exceed those from Israel, Greece, and 185 other countries.
The primary use of coal in the U.S. is for electricity generation, and it became the leading fuel for generating electricity in the mid-20th century. The rise of coal-fired generation of electricity shifted to a decline after 2007 due to the increased availability of natural gas, decreased consumption, renewable power, and more stringent environmental regulations. The average share of electricity generated from coal in the US has dropped from 52.8% in 1997 to 19.7% in 2022, and coal consumption in 2022 was the lowest percentage share since at least 1949.
The decline in coal usage can also be attributed to the retirement of very old coal-fired generating units and the implementation of environmental regulations such as the Clean Air Act of 1970 and the Environmental Protection Agency's (EPA) Cross-State Air Pollution Rule (CSAP). In 2018, 16 out of 50 Federal States of the US had either no coal power in their public power supply or less than 5% coal in power production. The shift away from coal is expected to continue, with financial markets viewing the future of coal as risky and less attractive for investment.

The US has not built a new coal plant since 2013
The United States has historically been the world's biggest carbon polluter, with its large cars, big houses, and heavy use of air conditioning. In 2017, the US withdrew from the Paris Climate Accord, a deal between 195 nations to combat climate change. This was a major setback in the fight against global warming.
Despite this, the US has not built a new coal plant since 2013, when the Sandy Creek Energy Station in Texas was connected to the grid. This shift away from coal is due to a variety of factors, including the increased availability of natural gas, decreased consumption, the development of renewable power, and stricter environmental regulations. The average share of electricity generated from coal in the US has dropped from 52.8% in 1997 to 19.7% in 2022. This decline in coal-fired power generation has been significant, with a 40% reduction over the last decade.
The US still relies heavily on outdated technology and limited resources for its electricity needs. Power plants are the largest source of US carbon dioxide (CO2) emissions, the main pollutant driving global warming. Coal is the biggest culprit, supplying just under half of America's electricity and emitting more than 80% of CO2 pollution from US power plants in 2007. The oldest power plants are the dirtiest, with those built before 1980 producing 73% of US CO2 emissions from power plants.
To address global warming, the US needs to continue transitioning away from coal and investing in renewable energy sources. The Inflation Reduction Act includes plans to invest $370 billion over ten years into wind, solar, green hydrogen, nuclear energy, and other non-fossil fuel power sources. This shift towards cleaner energy sources is critical to reducing the US's carbon footprint and mitigating the worst effects of climate change.

The US has invested $141 billion in clean energy
The United States is historically the biggest carbon polluter in the world. With its reliance on big cars, large houses, and air conditioning, it has contributed more than any other country to the atmospheric carbon dioxide that is heating the planet. The typical American burns roughly twice as much carbon as the average person in Europe or Japan, and 10 times as much as the average person in India.
However, the US has also been taking steps to combat climate change. In 2023, the US invested $141 billion in clean energy, with a focus on wind, solar, green hydrogen, nuclear energy, and other non-fossil fuel power. This investment has continued to grow, with US cleantech investment hitting $147 billion in the first six months of 2024, a more than 30% increase from the first half of 2023.
The US has also seen a decline in coal-fired power generation, with a 40% reduction over the last decade, and no new coal plants built since 2013. The Biden administration has set ambitious targets for reducing emissions, aiming for a 50-52% reduction below 2005 levels by 2030 and a commitment to stop new emissions by 2050.
While the US has made strides in clean energy investment, it is important to recognize the impact of its historical emissions and continued reliance on fossil fuels. The country's long-time dependence on fossil fuels, particularly coal, has polluted the air, land, and water, and fueled global warming. To effectively combat climate change, the US must continue to prioritize investments in clean energy and work towards reducing emissions and adopting more sustainable practices.
