pie chart - compare energy sources in 2 years KyyN0
The pie chart compares the proportion of five different energy sources including oil, natural gas, coal, hydroelectric power, and nuclear power for the USA in 1980 and 1990.
Overall, oil and natural gas accounted for the major sources of energy production in both years. However, over a decade, the usage of these two energy sources reduced slightly while there was an increase in production from coal and nuclear power.
In terms of the main energy sources, oil was the most common source of energy production, which made up 42% in 1980. Although the amount of energy produced by oil declined by 9% to a third (33%), this was still the most significant energy source for the USA in 1990. This trend of usage was also similar to the one of natural gas. In 1980, natural gas was the second major source of energy production, comprised of 26%, and this, then slightly dropped to 25% in 1990.
In regard to other less common sources of energy, the pie chart showed upward trend in using nuclear power and coal whereas the proportion of hydroelectric power remained the same at 5% over ten-year period. As such, the amount of energy generated by nuclear power doubled from 5% in 1980 to 10% in 1990. Similarly, there was a 4% rise in energy from coal to reach 27% in the second year.
