The pie charts illustrate the distribution of energy production from different sources in 1995 and 2005, showing the percentage contribution of coal, gas, petro (oil), nuclear, and other sources.
Overall, between 1995 and 2005, there was a slight increase in the use of coal and gas, a significant decrease in the use of petro, and an increased reliance on nuclear and other sources. This indicates a shift towards a more varied energy mix, with some movement away from oil and a growing emphasis on alternative energy forms.
In 1995, energy production was primarily dependent on coal, gas, and petro, each contributing roughly equal shares. Coal accounted for 29.80%, gas for 29.63%, and petro for 29.27%, indicating a nearly balanced reliance on these fossil fuels. Nuclear energy made up 6.40% of the total energy production, while other sources contributed the least, at 4.90%.By 2005, there were some changes in the energy mix. The share of coal slightly increased to 30.93%, making it the largest contributor.
Gas also saw a slight increase to 30.31%, maintaining its importance. However, the percentage of energy produced from petro decreased significantly to 19.55%, indicating a reduced reliance on oil. In contrast, nuclear energy nearly doubled its share to 10.10%, reflecting a growing focus on this alternative energy source. The “Other” category also saw a notable increase, rising to 9.10%, which suggests a diversification into new or less traditional energy sources.
