At one point, nuclear power provided 25% of Germany's electricity. But the fallout from Chernobyl, both political and real, led to a moratorium on construction and an initial planned phaseout of all nuclear reactors by 2022. That deadline subsequently was extended to 2032, but after the events at Fukushima in Japan, the phaseout policy deadline reverted back to two years from now. Today, Germany gets 11% of its electricity from nuclear sources. A study from the National Bureau of Economic Research measures the fallout.
