The pie charts provided depict alterations in the energy production composition of a country in 1985 and 2003.
Over the span of 18 years, there have been notable shifts in the energy production landscape of the country. While oil retained its prominence as the primary energy source in both years, there were considerable changes in the proportions of other energy resources.
In 1985, oil was the primary energy source, accounting for a substantial 52% of production. This was followed by nuclear energy, which held a significant share of 22%. In stark contrast, coal and natural gas contributed 8% and 13%, respectively. Hydroelectric power and other renewables comprised smaller fractions at 4% and 1%, respectively. However, by 2003, oil’s share had decreased to 39%, reflecting a notable shift. Concurrently, natural gas experienced a substantial rise to 23%, surpassing both oil and nuclear energy.
Coal also saw a significant increase, rising to 22% by 2003, marking a considerable elevation from its 1985 proportion of 8%. Despite fluctuations in other energy sources, nuclear energy maintained its share at 8% in 2003. Hydroelectric power and other renewables remained stable at 4%, each maintaining their positions in the energy mix. This shift in energy production highlights a diversification strategy, likely influenced by factors such as economic considerations, environmental concerns, and geopolitical dynamics.
