The pie charts illustrate the amount of energy capacity in gigawatts from 2012 to the expected proportion in 2030.
Overall, it is noticeable that the annual capacity is expected to double from 5.579 to 10.569 gigawatts, although the proportion of fossil fuels, despite being projected to experience a threefold decrease in 2030, will still constitute the largest amount of energy capacity. Similarly, the amount of flexible capacity is expected to double, though still maintaining the lowest proportion of the overall power output. It is evident that the figures for solar and wind capacity are expected to experience a significant surge, while the proportion of nuclear energy will remain relatively stable over the period given.
It is evident that the proportion for fossil fuels, initially accounting for 64%, is predicted to experience a decline of 20% in 2030. Moreover, the smallest amount of energy output throughout the period, occupied by flexible capacity, is expected to double over the years from 1% to 2%.
By contrast, the proportion of solar energy is expected to soar from 2% to final 18%, becoming the third largest figure of the overall capacity. Additionally, solar energy is expected to be more than two times higher in 2030 than in 2012, comprising of 5% and 12% respectively. The amount of nuclear energy, however, is predicted to undergo minor changes, falling from 6% to 5% over the period given.
