The pie charts compare the proportion of energy capacity in gigawatts in 2012 with the predictions for 2030.
Overall, on the both pictures we can see dominance fossil fuels and other renewable energy over others. And at all energy capacity will grow 2 times (form 5.6 to 10.6 gigawatt) Interesting that wind and solar capacity, which occupied only 7 percents of all energy in the past, will occupy one of the most part of capacity by the year 2030 (30%). I think this fact will happen because of trend of saving environment.
At the past, in year 2012, on the second place of energy capacity was nuclear (6%), but in the future capacity of nuclear power will move to fourth place (5%). Also, in the future, without big changes will be flexible capacity, grow from 1 to 2 percents.
Generally, on the pie charts of past and future we can see big grow and development of energy capacity
