Coal continues to be the main fuel used to generate electricity in the united states this is partly because the nation's coal reserves are incredibly huge.
The majority of the nation's electricity was produced by coal, nuclear energy, and natural gas in 2020, according to the U.S. Energy Information Administration.
What is the major disadvantage of using coal as a source of energy?
Coal's adverse effects on the environment are one of its main drawbacks. The majority of air pollution and greenhouse gas emissions come from coal-burning power plants. Use of coal results in the release of sulfur dioxide, a dangerous gas connected to acid rain, along with carbon monoxide and heavy metals like mercury.
Bituminous, subbituminous, or lignite coal can be burnt in coal-fired power plants. In order to turn water into high-pressure steam that powers a turbine that generates electricity, the heat generated by the coal's combustion is utilized.
Fossil fuels, including coal, natural gas, petroleum, and other gases, accounted for around 61% of the electricity produced in this country. Nuclear energy accounted for roughly 19% of the total, and renewable energy sources accounted for roughly 20%.
