The given pie charts illustrate the percentage of energy capacity in gigawatts in 2012 with the prediction for 2030.
Overall, it is clear that fossil fuels accounted for the most significant proportion in 2012 and in 2030, while flexible capacity contributed the least in 2012 and 2030. Additionally, the gigawatts in 2012 was 5.579, and in 2030, the gigawatts will rise to 10.569.
To begin with, in 2012, fossil fuels accounted for the highest proportion at approximately 64%, followed by other renewable energy at 22%. Meanwhile, flexible capacity represented only 1%, which was significantly lower. Other energies such as wind and nuclear shared relatively similar percentages, 5% and 6% respectively. Additionally, solar energy accounted for nearly 2%.
By 2030, there will be some remarkable changes. Solar energy will experience a significant rise to 18%. In contrast, fossil fuels are expected to drop noticeably to just 44%. Similarly, other renewable energy is predicted to decrease from 22% to 19%. Furthermore, the nuclear energy will decline slightly to 5%. Wind energy will see a substantial rise to 12 %. Additionally, there will be a slight increase in flexible capacity to around 2%
