The pie graphs display the comparison between the proportions of energy capacity, measured in gigawatts, in 2015 and in 2040.
Overall, while the figures for solar and wind energies are expected to increase, the reverse is evident for the remaining trends. Notably, although the proportion of fossil fuels is predicted to fall, it dominates charts in both years.
Starting with the types of energy that will dwindle, the share of fossil fuels constituted the largest proportion, with a beginning data point of just above half, and then will decrease significantly by 20% in 2040. It is distantly followed by the percentage of other renewables with 23% at the outset, and later is expected to drop marginally by 2%. In comparison, the figure for nuclear energy does not illustrate a remarkable change, reaching 5% in 2040 from 6%.
Turning to others that witnessed an upward trend, even though the percentage of solar enegy accounted for the least at 2%, it is going to illustrate the largest rate of change, emerging as the third biggest at 18%. The share of wind energy comprised 5% in 2015, and then is predicted to reach 12%, more than doubling its initial level.
