Trump Says "Coal Is Back," But Use Of The Rock At A 41-Year Low

President Donald Trump likes to tout coal, calling it "indestructible" and proclaiming that "coal is back." Around the U.S., use of the fossil fuel shows a different trend: Coal consumption is at its lowest level in more than 40 years.

That's according to the latest data from the U.S. Department of Energy, which on Monday said coal usage fell to 687 million short tons, its lowest since 1978. Production also fell to its second-lowest level since 1978, the agency said. 

Most of that coal is used to produce electric power. Despite the decline in both production and demand, the Trump administration is investing in the coal industry, with the Energy Department on Monday pledging $39 million for research into improving the efficiency of coal plants.
