The graph below illustrates the power generation capacity in German between 2008 and 2014.
Overall, before 2011 none of presented powers gained more than 30 gigawats. Nevertheless, in 2011 the capacity on wind power increased sharply up to 50 gw just in 1 year. After that change, it continued to rise, but slowly. Similar trend occurred with solar power- it reached about 25 gw in 2011 and then rised up to approximately 40 gw in 2012.
It is also noticeable how stable were oil and coal from 2008 to 2014. The amount of gigawats did not change quite. The capacity of nuclear power were also stable, but in 2010 it suddenly dropped from 20 gw to slightly up to 10 gw, until it gained 10 gw 2014.
To sum up, from 2008 to 2014 in Germany wind power and solar power capacity rised dramatically, while oil and coal had quite no changes. Only nuclear power had dropped.
