The given pie charts provide statistical comparison the main sources of energy in the USA in 1980s and the 1990s
According to the data given, most energy in 1980s (42%) was oil which is 9% more than in 1990s (33%). The second largest energy was natural gas in 1980s (26%). The coal was the third most source of power in 1980s and only one in twenty percentage of energy were hydroelectric power and nuclear power. However in 1990s the nuclear power increase to 5% and the same raising with coal energy. The sector shows that, the natural gas in 1990s did not change significantly as a other energy sources and modified just one percent.
In conclusion, not taking the one percent deterioration of natural gas, in 1980s and 1990s hydroelectric power and
