The pie charts compare the percentage of energy produced from five different sources in a specific country in the years 1995 and 2005.
Overall, coal and gas remained the most significant sources of energy in both years. However, there was a notable shift in the remaining sectors: while the reliance on petrol (petro) decreased significantly, the production of energy from nuclear and other sources saw a substantial rise.
In 1995, the energy production was roughly evenly distributed among the top three sources. Coal accounted for 29.80%, followed closely by gas at 29.63% and petrol at 29.27%. By 2005, coal and gas had increased their shares slightly to 30.93% and 30.31% respectively, maintaining their dominance in the energy market.
In contrast, the use of petrol dropped dramatically over the decade, falling from nearly 30% in 1995 to just 19.55% in 2005. This decline in petrol was offset by increases in the remaining categories. Nuclear power production rose from 6.40% to 10.10%, and energy from ‘other’ sources nearly doubled, growing from 4.90% to 9.10%.
