The two graphs show the main sources of energy in the USA in the 1980s and the 1990s.

Write at least 150 words.

The pie charts below compare the percentage of five major energy sources in the USA between the 1980s and the 1990s.

Overall, it is clear that unrenewable energy such as oil, coal and gas in both periods accounted for the largest proportion. While the figures for natural sources like oil and gas had tendency to decrease, the percentage of nuclear power increased.

In the 1980s, the proportion of oil was 42%, but this fell to 33% in the 1990s. However, oil was still the main source of energy from the 1980s to the 1990s. The percentage of natural gas also went down slightly by 1% from 26% to 25% in the 1990s.

In contrast, there was an increase in the figure for coal from 22% in the 1980s to 27% in the 1990s. Likewise, the percentage of nuclear power was 5% of the total energy sources, it went up to 10% in the 1990s. Besides, hydroelectric power remained unchanged, at 5% in both periods.
