The provided pie charts aim to illustrate the comparison of various energy source capacities in gigawatts(GW) both in 2015 and the projected estimations for 2040.
Overall, it is evident that the amount of renewable source capacities will be increased in 2040, whilst the most striking transformation will be exhibited by fossil fuels, which was the majority of the total share in 2015, and will witness a drop of one-fifth of the total share. Moreover, wind and solar will exhibit an inclining trajectory, and they will comprise one-third of the total percentage when they are combined. The data reveals that the most insubstantial decrease will have been done by nuclear and other renewables, while other renewables will have one-fifth, and nuclear is predicted to remain almost the same with 2015’s percentage.
In the first instance, it is clear that fossil fuels constituted 64% of the total share, and will account for 44%, will remain as the biggest count over the course of 25 years. In addition, other renewables had 23%, and it is estimated that it will see a slight drop of %2, reaching 21% in 2040. Moreover, nuclear energy capacity, which was 6% of the total proportion in 2015, will decline to 5%, being the minority of the pie chart.
Secondly, when it comes to sources that will exhibit an increasing pattern, solar energy, will increase almost 9 times to reach 18%, the third biggest share. Furthermore, it can be obviously seen that wind energy capacity will increase by 7%, accounting for 12% over a time span of 25 years.
