The pie charts depict a comparison of energy capacity proportions measured in gigawatts from 2012 and the predictions for 2030.
Overall, the usage of energy derived by various sources will predictably almost double. The most utilized source of energy in 2012 were fossil fuels and they will remain probably in 2030. It is worth mentioning solar energy that may increase noticeably in the future.
Over the year 2012, the energy capacity was about 5.500 GW and the two most essential sources of it were fossil fuels with 64%, as well as, other renewable power with 22%. The remaining minority was provided by nuclear, solar and wind powers and flexible power, with 6%, 2%, 5% and 1%, respectively.
Looking at predictions for 2030 the level of energy capacity will enhance to around 10.500 GW compared to the previous year. The fossil fuels and other renewables will keep their predominance, although fossil fuels will decrease approximately 20% in favor of solar and wind power turning to be the third and the fourth most significant players. The level of nuclear and flexible power will not change noticeably.
