The pie charts illustrate a comparison between the percentages of different types of Energy generators in gigawatts in 2015 with a future prediction in 2040.
Overall, Fossil fuels made up the majority of energy capacity in 2015 despite its proportion will decrease in 2040, it will still make the highest share. Wind and Nuclear had roughly the same percentages in 2015, however each will take a different turn in 2040. On the other hand, Solar was the lowest energy capacity in 2015, its predicted it will take a higher share than Wind and Nuclear.
For more details, in 2015, Fossil fuels made up the most of energy capacity among the other types of energy generators with 64% in contrast with Solar which was the lowest one with 2%, However, Solar will make a significant increase in 2040 to 18% and Fossil fuels will make 44%.
Regarding Wind and Nuclear, although they had nearly the same percentages in 2015 with 5% and 6% respectively, each will take a different trend in 2040 when Wind will have a dramatic climb up to 12% and Nuclear will have a slight decline to 5%. Other renewables will make 21% of the total energy capacity in 2040 after holding nearly quarter of the shares in 2015 with 23%.
