The pie charts depict the consumption of different sources of energy in the USA over a ten-year period from 1980 to 1990.
Overall, it can be clearly seen that oil remained the predominant energy source throughout the 1980s and 1990s, albeit with a decline in usage, accompanied by a similar trend observed with coal. In their stead, nuclear power emerged as a significant contender in the USA’s energy landscape.
In 1980, Oil accounted for slightly under half at 42%, which was the biggest number in the data, and this figure decreased by 9% in the last year. Natural gas was 26%, less doubled than the first one, and it declined by 1% in the final year surveyed.
On the other hand, Coal, which was the third in the graph, comprised almost a quarter of the chart in 1980, went up by 5% in 1990. Furthermore, in terms of Hydroelectric Power and Nuclear Power, both were similar percentages which are 5% in the first year, however, Nuclear Power’s number rose from 5% to 10% in 1990.
