The pie charts compare the proportions of five different energy sources used for electricity generation in a particular country in 1995 and 2005.
Overall, fossil fuels ( coal and gas) remained the dominant sources of energy production in both years. Additionally, while the reliance on petro saw a significant decline, all other categories grew by different amount/level, with the “other” category showing the most substantial relative increase.
In 1995, coal was the leading source of energy production at 29.80%, closely followed by gas at 29.63% and petro at 29.27%. By 2005, coal and gas remained the top two sources, experiencing minor increases to 30.93% and 30.31%, respectively. In contrast, the contribution of petro dropped sharply by nearly 10 percentage points, falling to 19.55% of the total energy output.
The remaining energy sectors, nuclear and other renewable/alternative sources, held the smallest shares but rose notably over the decade. Nuclear power rose from 6.40% to 10.10%. Similarly, the “other” energy category nearly doubled its share, increasing from 4.90% in 1995 to 9.10% by 2005.
