The pie charts give information about the comparison of essential sources of power for the USA in the year between 1980 and 1990. The data has been calibrated in percentage. Overall, it is vividly manifested that the oil was a main source of energy in both year. While, less contribution of energy production was hydroelectric power.
To begin with, in 1980, oil was a tops of the list among the all categories, it accounted for 42%. However, it was slightly decreased by 10% in next 10 year. There had been a constant contribution of hydroelectric power in both period around 5%, also it was the lowest produce power compare to others. There were minor differences observed in natural gas by only 1% from 1980 to 1990. Moving towards, in the year 1980, as regards nuclear power, it comprised to 5%, and experienced a twofold rise to one tenth percentage in 1990. The coal was produced 22% energy in 1980. While, it was rose in 27% in next decade, respectively.
