German solar power capacity grew by more than 7.6 gigawatt (GW) in 2012, which greatly exceeds the 2.5-3.5 GW increase German authorities would prefer over a year. This has forced the government to decrease subsidies on solar power, causing new installations to drop significantly during the fourth quarter of 2012. Businesses and politicians have raised concerns that the fast expansion of subsidised renewable energy might add to consumer costs and become a threat to economic growth, green energy production methods being more expensive than conventional ones. The German Environment Ministry expects an increase of 3.5-4 GW in 2013.
