Writing task 1: The various sources of electricity in the U.S.A

The two pie charts represent the various sources of electricity in the USA.

Describe the information by selecting the main infoemation and make comparisons where relevant. (150 words)

The pie charts indicate the variety of electrical origins in the USA in 1970 and 1984 by percentages. There are many ways to produce electricity which are by coal, by oil, by hydro – power and by nuclear. As can be seen, the electricity which is manufactured by coal had the biggest proportion in both 1970 and 1984, with 46% and 55.5%

According to the pie charts, in 1970, besides the biggest percentages of electricity made by coal, with 46%, most of electricity was produced by natural gas, hydro – power and oil. It was just 12.1 percent of electricity made by oil, which was about a half of the percentages of the electricity produced by natural gas, with 24.3%. There was very small amount of electricity made by nuclear, just 1.4%

It was clear that in 1984, electricity made by coal was still the most used electricity in USA with 55.5%. However, there were many changes in other origins of electricity. The percentage of electricity produced by natural gas was just as a half of the ones in 1970, with 12.3%. Electricity manufactured by hydro – power and oil were also lower than they were in 1970 with 13.7% of electricity made by hydro – power and just only 7% of electricity produced by oil. But the electricity made by nuclear was increased sharply, just from 1.4% in 1970 to 13, 5% in 1984.

To sum up, the electricity made by coal still had the biggest proportion. Other origins of electricity which was hydro – power, oil and natural gas was decreased gradually while the proportion of electricity produced by nuclear was rise sharply.
