Let's Explore Coal
Coal is the most abundant fossil fuel resource in the United States. Almost half of our electricity comes from coal-fired plants, meeting nearly a quarter of America's energy needs. According to the Energy Information Administration, today, coal is even more cleaner burning than ever before. Total SO2 (sulfur dioxide) emissions from coal-fired plants reduced by 85 percent between 1990 and 2015, and NOx (nitrogen oxides) emissions were reduced by 84 percent between 1990 and 2015. Coal is also the least expensive fossil fuel to use.
Before the first European settlers arrived, the North American Indians used coal to bake their clay pottery. By the 1800s coal was used for manufacturing goods, to make iron and steel, and later to power steam engines for ships and trains. By the end of the 1800s coal was used to produce electricity.
Today, coal is used to make electricity, and for smelting metals in the iron and steel industry (metallurgical coal is used for steel making). The paper, brick, cement, and limestone industries also use coal to make products.
In the United States, almost four tons of coal is used each year for each person. The state of Texas consumes the most coal, using about 100 million tons each year. The United States produces about 35 percent of the world's coal supply and exports a considerable amount. It is estimated that there is enough coal in the U.S. to last 180 years.
