The charts illustrate the expected changes of energy capacity in terms of gigawatts (GWh) over the period of 25 years.
According to the charts, about 5 gigawatts of energy is predicted to rise in future. Despite the dropping in proportion, fossil fuel seems to be the main resources for electricity production in both years. While solar being the least used up energy in 2015 is expected to wind up dramatically by 2040.
From overall view, the longest share in 2015 was fossil fuel accounting to 64%. It is assumed to have significant fall by 20%. On the other hand, nuclear and other renewables are going to be decreased slightly from 6% to 5%, and 21% respectively.
Furthermore, the energy gain from the sun is foreseen to have growth remarkably to 18 to 27 by the year 2040. Also, wind will raise up to more than two times resulting 12% from 5%.
