The pie charts illustrate the proportion of different sources (oil, hydroelectric, nuclear, coal, and natural gas) of energy for the USA in 1980 and 1990. Overall, the main sources of energy production remained oil, natural gas, and coal, which accounted for more than 50% in both years. An increase was observed in the production of […]
The pie chart compares the percentages of five different major sources of energy for the USA between 1980 and 1990. It is clear that the highest percentage of energy was produced from oil in 1980 and 1990. By contrast, the amount of energy produced from hydroelectric power in the USA was the lowest in the […]

The graph illustrates the different energy sources like oil, natural gas, coal, and hydroelectric power, nuclear power, for the USA in two different years, 1980 and 1990. Overall, the main source remained to be oil in both years, though the production reduced in 1990 along with natural gas, while the source contributing the least was […]
