After the Fukushima Daiichi Nuclear Power Plant accidents, anti-nuclear opposition intensified in Germany. On 12 March 2011, 60,000 Germans formed a 45-km human chain from Stuttgart to the Neckarwestheim power plant. On 14 March, 110,000 people protested in 450 other German towns, with opinion polls indicating 80% of Germans opposed the government's extension of nuclear power. On 15 March 2011, Angela Merkel said that seven nuclear power plants which went online before 1980 would be temporarily closed and the time would be used to study speedier renewable energy commercialization.
