The pie charts illustrate the percentages of energy produced from five different sources: hydropower, oil, nuclear power, coal, and ntural gases in the UK between 1983 and 2003.
Overall, the proportions of energy generated from oil and coal decreased, whereas natural gas showed a significant increase over the given period. Meanwile, the sharee of hydropower remained unchanged.
In 1983, the largest proportion of energy production came from oil, which accounted for 42% of total. By contrast, hydropower contributed the smallest share, at only 4%. Coal made up 23%, becoming the second-largest source, while nuclear power and natural gas represented 23% and 11% resectively.
By 2003, the proportion of oil had declined to 38%, though it still remained the dominant energy source. The percentage of natural gas nearly doubled, reaching 21%, making it the second most important source. In contrast, coal fell sharply to 13%, and nuclear power increased slightly to 24%, while hydropower stayed constant at 4%.
