The pie charts illustrate the allocation of various types of energy production in one country. The graphs provide information from 1990 to 2010.
Overall, it is clear that coal accounted for the largest share of energy production in both years and showed a significant increase. By contrast, hydro represented the smallest proportion (despite the other types), also it showed a slight decrease. Meanwhile, gas and nuclear types of energy production fall moderately
Referring to the pie charts, in 1990, coal accounted for about roughly 30% of energy production, which was the highest proportion, whereas other types (not coal, hydro, nuclear, gas) was the lowest, exactly 10%. In 2010, coal and other types stood 40% and 15%.
Moving on other types, the percentage of the gas was exactly a quarter in 1990 and decreased to 20% in 2010. The nuclear category accounted for 20% in 1990 and declined to 15% in 2010. Hydro fell from 15% to 10% from 1990 to 2010.
