Solar energy fiasco in Germany

Solar Subsidy Sinkhole: Re-Evaluating Germany's Blind Faith in the Sun - SPIEGEL ONLINE
...The only thing that's missing at the moment is sunshine. For weeks now, the 1.1 million solar power systems in Germany have generated almost no electricity. The days are short, the weather is bad and the sky is overcast.

As is so often the case in winter, all solar panels more or less stopped generating electricity at the same time. To avert power shortages, Germany currently has to import large amounts of electricity generated at nuclear power plants in France and the Czech Republic. To offset the temporary loss of solar power, grid operator Tennet resorted to an emergency backup plan, powering up an old oil-fired plant in the Austrian city of Graz.

Solar energy has gone from being the great white hope, to an impediment, to a reliable energy supply. Solar farm operators and homeowners with solar panels on their roofs collected more than €8 billion ($10.2 billion) in subsidies in 2011, but the electricity they generated made up only about 3 percent of the total power supply, and that at unpredictable times.

The distribution networks are not designed to allow tens of thousands of solar panel owners to switch at will between drawing electricity from the grid and feeding power into it. Because there are almost no storage options, the excess energy has to be destroyed at substantial cost. German consumers already complain about having to pay the second-highest electricity prices in Europe.
