The pio charts depict the source of energy in the periods 1980 and 1990 in USA. the graph shown that the oil and the natural gas with the coal have almost 90% of sources in the USA during each period.
According to what shown, the oil in 1980 was the highest percentage while the natural gas and the coal equal to 50% of the sources. In 1990 the oil decreased speedily to 33%, also the natural gas has simple fall unlike the unclear power went up to 10% which is twice what it was in 1980, but the hydroelectric power remain stable. the coal has increased from 22% to 27% which is reasonable increase.
To sim up, we could say that the sources which have the 90% of the energy in 1980 still have the largest part even though it was some of them decreased while another increased.
