Coking coal must be low in sulfur and requires more thorough cleaning than coal used in power plants, which makes the coal more expensive. In 2017, the average delivered price of coal used to make coke was about per short ton—about three times higher than the price of coal delivered to the electric power .
Of all the fossilfuel sources, coal is the least expensive for its energy content and is a major factor in the cost of electricity in the United States. However, burning coal in electric power plants is a major source of carbon dioxide (CO2) emissions, and its use has other repercussions as well. Mining coal disturbs the land and modifies the ...

A 2009 National Academy of Sciences report, Hidden Cost of Energy: Unpriced Consequences of Energy Production and Use, found that the external costs of coal from US coalfired power plants add up to over 62 billion in environmental damages a year.
In 2006, Connecticut''s coalfired power plants produced million tons of CO 2, 3,000 tons of sulfur dioxide, and 2,000 tons of nitrogen oxide; coalfired power plants were responsible for % of the state''s total CO 2 emissions. In 2005, Connecticut emitted tons of CO 2 per person, about 40% less than the average.
Coal also is the most used fossil fuels for producing electricity as we use coal power plant for producing around 40% of the world''s electricity, and we commonly use it in cement manufacturing and industrial purposes such as refining metals.
Duke Energy has been using coal to produce electricity in the Carolinas since 1911. Those first coalfired plants (in Greensboro,, and Greenville, ) only supplemented the company''s use of hydroelectricity. In the 1920s, the growing demand for electricity began to outstrip the availability of hydroelectric generation.
Coal is the largest domestically produced source of energy in America and is used to generate a significant chunk of our nation''s electricity. The Energy Department is working to develop technologies that make coal cleaner, so we can ensure it plays a part in our clean energy future.
