The two pie charts illustrate the ratio of energy capacity in gigawatts, one is from 2015 and the second one is a forecasted for 2040.
Overall, the projections for total energy capacity will be nearly double, the usage of fossil fuels will fall however solar and wind capacity will increase dramatically.
The proportion of fossil fuels, which is estimated to decrease from 64% in 2015 to 44% in 2040. Similarly, Nuclear and other renewables fuels were 6% and 23% respectively in 2015 and expected to decrease to 5% and 18% in the year 2040.
On the other hand, solar energy is expected to rising from 2% in 2015 to 18% in 2040, and wind energy is forecasted increase from 5% in 2015 to 12% in 2040. In addition, the total energy capacity will almost double, increasing from 6.688 GW in 2015 to 11.678 GW in the year 2040.
