The provided visual representations depict the proportion of energy production from various sources in a specific country during the years 1985 and 2003.
Overall, it is evident that there were notable changes in the composition of energy production between the two years. The most significant alteration was the decrease in the proportion of energy generated from coal, while natural gas and oil experienced considerable increases.
In 1985, the primary source of energy production was coal, accounting for 52% of the total output. This was followed by oil at 22%, natural gas at 13%, nuclear at 8%, and hydro and other renewables at 4% and 1%, respectively. Notably, coal held the dominant share, while other renewable sources made up the smallest contribution to the energy production mix.
By 2003, there had been a perceptible shift in the energy production landscape. Coal’s share decreased to 39%, making it no longer the dominant source, while the proportion of natural gas and oil witnessed significant increases, reaching 23% and 22% respectively. Interestingly, the proportion of other renewable sources also doubled to 4%, indicating a growing emphasis on diverse renewable energy options.
