The two pie charts show the proportion of energy capacity from different sources in 2015 and the prediction for 2040, measured in gigawatts (GW).
Overall, fossil fuels were the main source of energy in 2015, but their share is expected to decrease in 2040. At the same time, renewable energy sources such as wind and solar are predicted to increase. In addition, the total energy capacity will grow from 6.688 GW to 11.678 GW.
In 2015, fossil fuels made up the largest part of energy production at 64%. Other renewables were the second biggest source, accounting for 23%. Nuclear energy represented 6% of the total capacity, while wind power made up 5%. Solar energy had the smallest proportion, at only 2%.
By 2040, the share of fossil fuels is predicted to fall significantly to 44%. Solar energy is expected to increase greatly to 18%, and wind power will also rise to 12%. Meanwhile, other renewables will slightly decrease to 21%, and nuclear energy will go down a little to 5%.
In conclusion, renewable energy sources are expected to become more important in the future, while fossil fuels will decline.
