The given graph shows the main sources of energy for USA in 1980 and 1990.
The pie graphs represent information about the percentage of power used in America from 1980 to 1990.
The data has been calibrated in percentile.
After analysing the pie charts, it can be seen clearly that a negligible distinction was seen in natural gas which was the main source of energy for the USA in both years.
In contrast
, 5% nuclear power was used in United State, while
twofold in the later year. In 1980 and 1990, an identical ratio of hydroelectric power was consumed by citizens of America.
Moving further
, 42% of the oil was used in 1980, but in 1990, it declined by 9%. However
, a difference of 5% was seen in the utilization of coal by Americans in both pie figures.
Overall
, it is crystal clear that the maximum proportion of oil was in the former year, whilst in the latter year, the minimum energy was used hydroelectric fuel in America.Submitted by deepikanayyar1996
