the two pie charts demonstrate the manufacture of energy in a specific country over two decades, from 1983 to 2003.
Overall, there were minor fluctuations in the proportions of various energy sources, with the oil remaining the dominant source throughout the period while hydropower maintained a consistent share.
In 1983, oil was the principal energy source, accounting for 42% of total energy prooduction. Coal followed, contributing 23% of the energy, while nuclear power made up 20%. Natural gas represented 11%, and hydropower was the least utilized energy source at 4%.
By 2003, oil’s share slightly decreased to 38%, while natural gas’s percentage increased gradually to 24%. The proportion of nuclear power share the same trend with oil, decline to 13%, which was nearly doubled compared to the previous percentage. Natural gas’s contribution to the total energy produce saw a notable increase from 11% in 1983 to 13% in 2003, while hydropower remained unchanged at 4%
