The pie chart illustrates the percentage of energy in different categories in the USA in 1980 and 1990.
Overall, it is clear that the amount of old and natural gas used by US citizens was the majority proportion in both years, while the remaining items had a gradual increase.
In 1980, Oil was the primary source of energy in the US, at 42%. However, its number decreased by precisely 9% to reach 33%, which was also the highest point in 1990. Moreover, natural gas was the second highest at 26% in 1980 and slightly fell to 25% in 1990.
The percentage of people who used coal energy accurately was 22% in 1980 before increasing to 27% in 1990. The figure for nuclear power reached 5% in 1980, after undergoing a rise to 10% in 1980. Finally, there was no change in the amount of hydroelectric power used in the US, at exactly 5% in both years.
