The two pie charts illustrates the different proportion of electric energy production, which is a major source of energy between 1970 and 1984 in USA. It also provides figures including natural gas, hydro-electric power, coal, nuclear and oil.
Overall, it is evident that, a significant increase in the proportion of Nuclear can be noticed over the period while oil consistently accounted for the same proportion that is 5% in both of the years.
First of all, the percentage of energy produced by coal started at just over 55. 50% in 1970. Besides, this figure then rose slightly to reach a peak of almost 55. 5% in the year of 1984. Intriguingly, before 1984 the number of hydroelectric power falling drastically to 13. 7% in the following year.
In terms of oil the rate remained relatively stable in both of the years about 5% and 5% respectively. However, the proportion of nuclear climbed gradually to peak at about 13. 5 % in 1984.
