The pie chart displays the proportion of different kinds of energy capacity in gigawatts in 2015 and the predictions for 2040. The main resources of energy capacity are come from fossil fuels, winds, nuclear, solar, and other renewable energy.
Overall, the gigiwatts will steady increased from 6688 GW in 2015 to 11678 GW in 2040. The proportion of fossil fuels account for 64% of total energy capacity in 2015, highlight its dominance in generating energy. However, usage of fossil fuels will declined, with a proportion of 44% by 2040.
Looking at the details, the proportion of other renewable energy capacity remained stable during 25 years, ranged from 21% to 23%. While the proportion of wind energy has obvious increased from 2% to 18% over the past decades, the nuclear energy capacity remained relatively stable.
Interestingly, the proportion of solar energy capacity was lower than other kinds of energy in 2015. In the coming 25 years, it witness a dramatic increased. started at 2% and ended at 18% in 2040.
