The pie charts provide information about two percentages of energy capacity in gigawatts in 2015, along with the predicted portions for 2040.
Overall, fossil fuels accounted for the largest portion of energy; however, it was predicted that this percentage would likely decrease in the coming years. Additionally, another notable feature is that solar and wind energy are expected to increase, whereas the rest of the energy sources would decline.
The energy capacity started at 6.688 gigawatts in 2015, but will slowly rise until 2040, with 11.678 GW. Fossil fuels were the most used source of energy in 2015, accounting for exactly 64 %, more than half of the proportion. The forecast recorded a marginal drop of 20 % as seen in the charts.
Other renewables were about 23% in proportion in 2015, until it was foretold that they would slightly fall in 2040. Conversely, nuclear, wind, and solar occupied approximately a quarter percentage, with 6%, 5%, and 2%, respectively. Another point to notice is that it is projected that solar and wind energy will record a dramatic increase (16% and 7% ) in 2040, while nuclear dropped 1%.
In summary, people’s usage of energy has varied and changed over the period, and may lead to better and accessible source of energy.
