One technical factor holding the United States back is its legacy energy grid which would have difficulties handling a large proportion of fluctuating energy production. Yet the United States has more potential solar energy than Germany, known for its leaden skies. At the end of 2012 the country had installed more solar power capacity in the world thanks to large government incentives. In contrast the United States still allows hugely profitable international oil companies a depletion allowance among other lucrative US tax subsidies. In 2013 the American oil and gas industry averaged 20 spills per day. German solar power has reached grid parity meaning once all costs are accounted for the price of commercial solar is equal to retail electricity rates. Citizens pay a surcharge for clean energy, but have the opportunity to gain it back by installing their own photovoltaic system for as little as $600. Citizens, cooperatives and communities own more than half of German renewable capacity which is one reason monopolistic fossil fuel companies are desperately fighting society-wide conversion to renewable energy in the United States. Wind power in Germany reached record output levels last year, accounting for 39% of electricity supply on a single December day.

However, green energy experts point out that Germany is only temporarily replacing expensive natural gas. German power prices for 2014 sagged 17% as renewable production surged and consumption fell to 2009 levels.
