Writing task 1: The main sources of energy

The pie charts give information about the proportion of five different sources of energy in the USA: oil, natural gas, coal, hydroelectric power and nuclear power between 1980 and 1990. It is noticeable that the amount of oil-consuming decreased and that of hydroelectric power still maintained. By contrast, there was a significant growth in the amount of coal and nuclear power using as one of the main sources.


Oil consumption accounted for 42% in 1980. Despite its dramatic decreasing to 33%, oil was still has a good proportion in 1990. The percentage of natural gas-consuming also saw a slight decline but only decreased from 26% to 25%. That of hydroelectric power remained at 5% after ten years.


On the other hand, the proportion of using nuclear power was similar to the percentage of hydroelectric power in 1980, at exactly 5 percent. This then made up about 10% in 1990 while the rate of coal-using grew from almost a fifth to just under a third.


I appreciate all your feedback!
