In Germany, the installed capacity of renewable power stations has increased significantly during the last years. Since 2000 wind power has the highest capacity of all renewables although hydroelectric power stations normally have more full load hours per year. Photovoltaic installations have also grown rapidly during the last years. The total installed capacity of power stations in Germany has risen due to the newly installed renewable power stations whereas the capacity of conventional power station has decreased since beginning of the 1990s. The renewable share of the total capacity has increase more than six times since beginning of the 1990s and reached double-digit numbers. Since the year 2004 the installed renewable capacity in Germany is higher than the nuclear power capacity.
