The charts show the proportion of the energy produced from different sources in a country between 1985 and 2003. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.
The provided pie charts contrast a country’s energy generation from different sources (natural gas, coal, hydrogen, nuclear, oil and other renewables) as a percentage of total energy generated between 1985 and 2003.
It is evident that as time went on, the amount of energy produced by some sources increased while that of others decreased. From 1985 to 2003, oil produced the most energy overall, while hydrogen and other renewable sources produced the least.
Despite a decline in usage from slightly over half (52%) in 1985 to roughly two-fifths (39%) in 2003, oil remained the primary source of energy production during the entire period. During that time, nuclear usage also decreased, falling from 22% to 17%.
Between 1985 and 2003, the percentages of natural gas and coal used increased from 13% and 8%, respectively, to 23% and 13%, respectively. It’s interesting to note that during the course of the 18-year period, the amount of energy generated from hydrogen stayed constant at 4%, while that from other renewable sources grew from 1% to 4%.
