Montana, the state which has the largest recoverable reserves of coal in America and which produces 5% of the country’s coal, generates more than half of its electricity from this fuel. The other half is generated mainly from hydropower as the state exploits benefits of Missouri River. Montana uses only half of produced electricity, and the rest is distributed to other states.
