The graphs compare data about 5 main sources of produced energy in USA in 1980 and 1990.
Overall, it is clear that, in both years, oil maintained dominance in energy generation, while h/power and coal constituted the least part of it.
Turning to the details, being 26% in 1980, the amount of energy produced from natural gas experienced a slight decline by 1% in 1990. Similarly, having the most proportion in energy generation in 1980 comprising for 42%, oil segment decreased remarkably to 33% in 1990. Meanwhile, the amount of energy generated from h/power stood at the same level in both years making up 5%.
On the other hand, being just under a quarter in 1980, coal segment witnessed a remarkable increase to 27% in 1990. Similarly, having the same proportion with h/power in energy production in 1980 constituting for 5% nuclear power doubled in 1990.
