"The three major fossil fuels—petroleum, natural gas, and coal—combined accounted for about 77.6% of the U.S. primary energy production in 2017:

Energy Information Administration FAQs:

"Different fuels emit different amounts of carbon dioxide (CO₂) in relation to the energy they produce when burned. To analyze emissions across fuels, compare the amount of CO₂ emitted per unit of energy output or heat content.

Pounds of CO₂ emitted per million British thermal units (Btu) of energy for various fuels:

"In 2016, about 728 billion short tons of coal were produced in 25 U.S. states. Surface mines were the source of 65% of total U.S. coal production and accounted for 62% of the total number of mines. About 0.9 million tons, or about 0.1% of total coal production, was refuse recovery coal.

The United States is a net exporter of coal. However, some coal is still imported, mostly for power plants on the eastern and southern coasts of the country, where it is cheaper to ship in coal by sea from South America than transport it from mines in the northern and western United States.¹
