The pie charts compare different resources in terms of their changing energy production in 1985 and 2003.
From an overall perspective, four of the six resources saw varying degrees of increase in their percentage of energy output, whereas the share of hydro energy remained stable from 1985 to 2003. We can also see that the oil producer produces the highest amount of energy production in each year. It is also worth noting that nuclear energy witnessed a significant decrease in its energy mix.
Looking more closely at the charts, in 1985 oil energy had the highest rate of energy production at 52%, followed by nuclear energy, which maintained 22% of energy output. In contrast, the figures for hydro, coal, and natural gas were significantly lower, standing at 4%, 8%, and 13%, respectively. Moreover, renewable energy witnessed the lowest proportion of the energy mix at 1%.
By 2003, hydro energy’s proportion in the energy mix showed a marked decline, standing at 39%. Similarly, the percentage of coal, natural gas, and other renewable energy production surged by 14%, 10%, and 3%, respectively. However, hydro energy maintained a consistent percentage in the energy output (4%). Meanwhile, the percentage of nuclear energy production diminished from 22% to 8%.
