United States

Power

Hydroelectric resources are heavily concentrated in the Pacific and Mountain regions. Hydroelectricity, however, contributes less than one-tenth of the country’s electricity supply. Coal-burning plants provide more than one-fourth of the country’s power, nuclear generators contribute about one-fifth, and renewable sources of energy constitute between one-tenth and one-fifth.
