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.

The following pie charts compare the total

production

of electricity using five different sources (wind, solar, nuclear, fossil fuels, and renewable) in 2015 and predict the changes in these sources in 2040.

Overall

,

it is clear that

energy

production

is expected to double in the next 25 years to nearly 12 GW.

While

the demand for fossil fuels declines in the future, for solar and renewable sources it is projected to rise. In 2015, the total

energy

production

stood at 6.688 GW, in which fossil fuels were the main source of

production

; it accounted for 64% of total

production

,

however

,

this

figure is expected to fall by nearly a quarter in 2040 and is expected to contribute only 44% of total demand. Renewable

energy

remains the second most important source of power

and is expected to remain in the position in the years to come, but a slight decrease of merely 2% is predicted. Looking at solar

energy

, accounted for a small share of only 2% in 2015, interestingly, the demand for it is predicted to soar significantly, and it is expected to reach 18%. The same goes for the wind, its proportion was only 5% and is expected to rise by 7%.
