Fuel and Energy Conversion and Equivalence Chart

Remember, the fuel price should not be the sole measure for selecting a heating appliance. To use the formula below, remember to use a decimal for the appliance heating efficiency you are assuming (see Table 2). You must first convert the Btu content of the fuel per unit to millions of Btu by dividing the fuel's Btu content per unit by 1,000,000.

What is coal? - USGS

Coal is primarily used as fuel to generate electric power in the United States. In coal-fired power plants, bituminous coal, subbituminous coal, or lignite is burned. The heat produced by the combustion of the coal is used to convert water into high-pressure steam, which drives a turbine, which produces electricity. In 2019, about 23 percent of...

Chapter 7 COAL - Pennsylvania State University

States has far more coal than gas and petroleum (compare Figures 7-1, 8-1 and 9-1). This suggests that, when supplies of gas and petroleum become scarce, it would be possible to turn to coal as our major fossil fuel energy resource. How long could we rely on domestic supplies of coal? There are many uncertainties involved in making such an ...
