Basically correct, yes. In the wake of Fukushima there were elections here in Germany. A ton of fear mongering was done with "omg nuclear power bad!" and gave the Greens (and other leftists) good predictions.
Merkel then decided to just end nuclear power in Germany. Thus she secured her next election win, cause the entire Green campaign was focused on closing down nuclear power plants. Merkel sacrified energy to stay in power, yes.
