August 8, 2012. German state development bank KfW plans to put up about 100 billion euros ($123.6 billion) to help finance the planned shift to renewable energy in Europe's biggest power market, it said. Chancellor Angela Merkel is struggling to implement the green revolution she announced, under which Germany will exit nuclear power by 2022 and shift to renewables. Problems include opposition from industry, ministerial infighting and high investment costs, especially in offshore wind. The KfW has long been mentioned as a possible source of credit for the huge upfront costs related to offshore wind.
