The pie charts indicate changes in the proportions of energy produced in a country from 1983 to 2003. Summarize the information by selecting and reporting the main features and make comparisons where relevant.

The given charts illustrate the percentage of energy which was manufactured in a nation between 1983 and 2003. As can be seen from the graphs, the proportion of nuclear power and hydropower witnessed an increase

while

those of Oil and Coal dropped from 1983 to 2003.

Moreover

, Oil was dominant during the research period. Looking at the pie charts more closely, one can see that the share of Oil reached a peak of 42% in 1983 before falling gradually to 38% in 2003. Following that, there was a sharp decrease in the percentage of coal from 23% to 13%

at the end

of the research duration.

In contrast

, the share of nuclear power accounted for 20% in 1983 before rising to 24% in 2003.

Furthermore

, the proportion of natural gas reached its highest point at 21% in 2003 from 11% in 1983.

In addition

, hydropower contributed stably to 4% in the share of energy in 2003.
