The amount of energy production by the oil was largest in the United States and accounted 42% in 1980 and then, the coal dramatically declined its output in 1990 yielding 33% only. The proportion of energy from hydroelectricity power, on the other hand, remained constant in both years 1980 and 1990 at a mere 5%. The energy generated from natural gas was a second largest source of energy which stood at 26% in 1980, while it declined slightly by only 1% in 1990.
