The main sources of energy of USA in 1980 and 1990.
The two pie charts depict the proportion of five primary sources of energy in the USA: oil, natural gas, coal, hydroelectric power and nuclear power between 1980 and 1990. It is noticeable that the percentage of oil decreased and that of hydroelectric power maintained. By contrast, there was a dramatic growth in the proportion of coal and nuclear power as one of the main sources.
Oil accounted for 42% in 1980. Despite its decrease to 33%, oil still had a good proportion in 1990. The percentage of natural gas also had a slight decline from 26% to 25%. That of hydroelectric power remained at 5%.
On the other hand, the proportion of nuclear power was similar to that of hydroelectric power in 1980, at exactly 5 percent. This made up about 10% in 1990 while the proportion of coal grew from almost a fifth to just under a third
