The two pie charts compare United states major energy source in 1980 and 1990. What stands out is, oil was the main source of energy in the both time frame, while hydroelectric and nuclear power generated the least amount of energy in USA. In all types of energy production there was only minimal change over the ten years period.
Energy produced by coal comprised 22% in the first year and this showed a slight increase of 5% to 27% in 1990. Likewise, in 1980, nuclear power generated 5% which rose to 10% ten years later.
For the purpose of this data, there was an approximate 10% drop in energy production from oil by 1990, whereas, it had preserved the largest energy source respectively. Turning next to the two last methods of producing energy, the natural gas and hydroelectric power, almost remained constant in the mentioned decade.
