The provided pie charts compare the sources of energy production in 1995 and 2005, showing the percentage contribution of various energy types, including coal, gas, petro (oil), nuclear, and other sources.
Overall, the decade between 1995 and 2005 saw a slight increase in reliance on coal and gas, a significant reduction in the use of petro, and a marked increase in the use of nuclear and other energy sources. These changes likely reflect evolving priorities in energy policy and technological advancements during that period.
By 2005, there were notable shifts in the energy mix. Coal’s contribution slightly increased to 30.93%, making it the largest single source of energy. Gas also saw a marginal rise to 30.31%, maintaining its strong position. However, petro experienced a significant decline, dropping to 19.55%, which indicates a shift away from oil as a primary energy source. On the other hand, nuclear energy nearly doubled its share to 10.10%, reflecting a growing emphasis on this alternative energy source.
The category labeled “Other” also saw a substantial increase, rising to 9.10%, suggesting diversification into renewable or less traditional forms of energy. In 1995, energy production was fairly evenly distributed among the main sources, with coal, gas, and petro each contributing nearly a third of the total. Coal accounted for 29.80%, gas for 29.63%, and petro for 29.27%, indicating a balanced reliance on these fossil fuels. Nuclear energy was responsible for 6.40% of the total, while other sources contributed the smallest share at 4.90%.
