The two pie chart compare information about the major resources in the USA in the years 1980 and 1990. Data about five various sources is represented in terms of percentage of total energy consumption.
Fistly, in regard to the use of oil, it accounted for 42% of energy consumption in 1980 but that significantly decereased to only 33% by 1990. Next, As an energy of source, natural gas very slightly decreased over the period from 26% to 25% of total consumption. Turning now to coal, the use of coal actually inclined over the decade, between 1980 and 1990 of total consumption. Especially, as an energy source, nuclear power in fact doubled in usage in those years from 5% to 10%, whereas hydroelectric power was the only source to remain constant, at 5%.
overall, as a source of enegy, oil recorded the most dramatic decline. While, the use of nuclear energy actually experienced the most significant increase, doubling over the ten years. The use of the other three sources remained more or less constant at silmilar propotions. |
