706,309,263 short tons of coal was produced in the U.S. in 2019, according to the 2020 Annual Coal Report of U.S. Energy Information Administration. Calculate the amount of energy that would be released if all of this coal was combusted. Assume an average energy density of 24 MJ/kg of all types of coal extracted. Remember to convert short tons (U.S. ton) to tonnes (metric ton).
