Main sources of energy in the USA in the 1980s and the 1990s
The two pie charts show the amount of energy produced by different sources in USA in 1980 and 1990. Overall, it is clear that oil remained the major source of energy through the 10-year period while the percentage of hydroelectric power stayed the lowest.
In 1980, the oil segment counted for 42% of total power consumption but lost 9% share during the following decade dropping dramatically to 33% by 1990. Meanwhile, natural gas and hydroelectric power were stable through 1980 to 1990. Likewise, the percentage of energy gained from natural gas decreased by 1% in 10 years and one quarter of total energy came from this source in 1990.
In contrast, as can be seen in the same period, percentage of nuclear power jumped from a mere 5% to 10%, which doubled its proportion of overall energy consumption. Turning to another important trend, the coal segment grew by 5% during the decade. This was 6% lower than the proportion of oil and 2% higher than that of natural gas, making it the second largest group of energy source.
