The pie charts below compare the proportion of energy capacity in gigawatts (GW) in 2015 with the predictions for 2040.
Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

Sample Answer
The diagrams describe how much electricity was produced from renewable and non-renewable energy sources in 2015 as well as some projections for the year 2040.
Overall, in 2015, most electricity was generated from fossil fuel while the least amount from solar. In 2040, fossil fuel will remain to be the main source of energy for electricity production, though its contribution along with that of nuclear and other renewables is expected to fall. However, the figures for solar and wind based electricity are predicted to rise. Of particular note is the total energy capacity, which is forecast to double.
In 2015, fossil fuel made up virtually two-thirds of the total electricity production, which was nearly three times as much as the figure for the second biggest electricity source – other renewables (23%). In sharp contrast, just about as much electricity was generated from wind as nuclear, at roughly 6%, while a tiny fraction of energy was solar, at 2%.
Electricity production scheme is predicted to change radically in 2040. Fossil fuel will remain to be the main source of electricity, but its figure will shrink by a fifth, dropping to 44%. On the other hand, the share of solar will grow nine-fold, reaching 18% while that of wind will more than double, constituting 12%. The figures for the remaining categories such as other renewables and nuclear are anticipated to decline negligibly, falling to 21% and 5% respectively. Finally, the total amount of electricity produced will nearly double, going from about 6.7 GW to 11.7 GW.
