The two graphs depicts the change of energy sources in the USA across 10 years period.
Oil in 1980 took up the largest share in the market, 42%, although it decreased to 33% in 1990. The usage of natural gas, as the second largest one in 1980, dropped 1% only. Coal supplied the third largest energy in 1980, increased its proportion from 22% to 27% and overtook natural gas becoming the second largest energy provider. Hydroelectric power and nuclear power made up equally 5% in 1980, with nuclear power doubled the market share in 1990.
In summary, the traditional energy sources were major power supplier, accounted for 85% in 1990, including oil, natural gas and coal, whereas the government began to invest high-tech energy sources, such as nuclear power.
