Coal production statistics from the US Department of Energy indicate that in 2007, the US produced (and presumably burned) 1.146 billion tons of coal. China produces and burns slightly more.
Coal isn't used all that much anymore. but some of the top mining areas in the US are PA, WV, Kentucky, VA, ND, and Wyoming.
About enough to make us last till 2030.
Yes, coal is found in Wyoming. Wyoming is the number one producer of coal in the US, with about 40% of the coal in the US coming from Wyoming.
The US had an abundance of coal and natural gas. It is estimated that 50% of the electricity generated in the US was from coal through burning fossil fuels.
Sadly unless it us a union mine (there are very few now) coal miners don't get retirements, barely even benefits.
Coal is very important to the US. It is the primary source of energy for the country.
