The demand for oil by the US people decreased from 42% to 33% over the decade, however, this percentage was the highest. Using natural gas was the second enery source that almost stayed stabil, like hydroelectric power. Hydroelectric power covers 5% of chart.

On the other hand, need for coal illustrates a slight increase with 5%. Coal become the second highest proportion in 1990 with 27%. Compared to the 1990, use of nuclear power also rose. In 1980, it was same percentage as hyroelectric use, but it increased to 10% over 10 years.
