Fossil fuel burning

Fossil fuels are nonrenewable energy sources used to generate electricity, heating, and transportation over the past two decades. The extraction and use of fuels such as coal, oil, and natural gas contribute to the carbon dioxide in the air. 

We use these fuels to produce energy in various manufacturing companies, to produce electricity, and to power big engines. We also use them to cook and provide heat when it's cold. We also use them to power transport systems like buses, cars, airplanes, and ships.  

Burning crude oil, coal, and natural gas produces enormous amounts of carbon dioxide in the air, making it the most significant contributor to global warming. In 2022, 81% of the United States' energy comes from coal, natural gas, and crude oil, so you can imagine the amount of carbon dioxide released into the atmosphere daily.

Fossil fuels contribute the most CO2 to the air. In 2023, the fossil fuel industry released 36.8 billion tons of carbon, with the United States being the world’s second carbon emitter after China4.
