The line graph illustrates the amount of power generated from renewable and non-renewable energy sources in Germany, from 2008 to 2014.
The graph shows a significant increase for wind and solar power, which are both renewable energy sources. However, unlike solar power which rised constantly, wind power had significant irregularities throughout the increase in the generation of energy. From 2008 to 2009, it rised from 10 GW to 25 GW, and remained nearly stable until 2011, before drastically soaring from 30 GW to 50 GW, and eventually, reaching 55 GW by 2014.
In contrast, nuclear power had a decline in producing power, remaining almost constant for 2 years, and ultimately decreasing by approximately 10 GW in 2011, which fell slowly to 5 GW by 2014. In addition, coal also had a slight fall in power generation capacity by around 8 GW in 2014.
Lastly, oil generally remained in a plateau throughout the years at 5 GW.
The overall graph implies that most power has been supplied by renewable energy sources such as wind and solar power, while non-renewable energy sources either had a slight reduction, or remained unchanged.
