What gases are released when coal is burned?
Carbon dioxide (CO 2) makes up the vast majority of greenhouse gas emissions from the sector, but smaller amounts of methane (CH 4) and nitrous oxide (N 2 O) are also emitted. These gases are released during the combustion of fossil fuels, such as coal, oil, and natural gas, to produce electricity. What happens when coal is burned?
How much carbon dioxide does coal emit?
Subbituminous coal in Wyoming’s Powder River Basin, the principal source of this rank of coal, has an emission factor of 212.7 pounds of carbon dioxide per million Btu. This is the same as for subbituminous coal in Colorado, but slightly below that in Montana.
Why is coal bad for the environment?
Chemically, coal is mostly carbon, which, when burned, reacts with oxygen in the air to produce carbon dioxide, a heat-trapping gas. When released into the atmosphere, carbon dioxide works like a blanket, warming the earth above normal limits.
What happens when coal is extracted from the Earth?
However, when coal and other fossil fuels are extracted and burned, they release sequestered carbon into the atmosphere, which leads to a build-up of greenhouse gases and adversely affects climate s and ecosystems. In 2011, about 43% of the electricity in the U.S. was generated from burning coal.
