Electric Power Generation in the United States by Fuel Type

Source: Energy Information Administration, 2005

There are several reasons why coal continues to be the most prevalent fuel used in U.S. electricity production, representing half of the total generation in the country:

• It is the most abundant domestic fuel source. The United States has enough coal reserves to produce energy for the next two centuries.
• It is inexpensive. Per unit of heat delivered, the cost of coal is about one-half to one-third the cost of oil and natural gas.
• It is readily available. Unlike natural gas and oil, coal supplies are not as affected by political events.

Using Coal More Cleanly

To take advantage of the low cost and availability of coal as a fuel source in a responsible manner, Mirant works to burn coal more cleanly. We have implemented a range of solutions and technologies to reduce emissions of sulfur dioxide (SO2), nitrogen oxides (NOx), particulate matter and other byproducts.

Please see the Mirant and the Environment section for details, including results of emissions monitoring»

More than 25 percent of the coal used at the Potomac River Generating Station comes from five mines in Virginia.
