Se pare că (și) germanilor le-a ajuns luxul aventurilor eco:
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.
The RWI also expects the green energy surcharge on electricity bills to go up again soon. It is currently 3.59 cents per kilowatt hour of electricity, a number the German government had actually pledged to cap at 3.5 cents. But because of the most recent developments, RWI expert Frondel predicts that the surcharge will soon increase to 4.7 cents per kilowatt hour. For the average family, this would amount to an additional charge of about €200 a year, in addition to the actual cost of electricity. Solar energy has the potential to become the most expensive mistake in German environmental policy.
In fact, all German solar energy systems combined produce less electricity than two nuclear power plants. And even that number is sugarcoated, because solar energy in a relatively cloudy country like Germany has to be backed up with reserve power plants. This leads to a costly, and basically unnecessary, dual structure. Figures indicating the peak performance of solar energy systems are easily misunderstood, a report by the German Physical Society says. “Essentially,” the report concludes, “solar energy cannot replace any additional power plants.”
