Since late 2012, the U.S. has announced the retirement of five reactors, and several planned units are currently on hold.
China is one of the only nations investing heavily in nuclear power—28 of its 49 reactors are under construction, and 35 more have been planned. It still has a long way to go: Nuclear accounted for only two percent of the country's electricity in 2012.
Just before the Fukushima disaster in 2011, nuclear power provided about 29 percent of Japan's electricity. As of late 2013, all of its reactors were shut off and producing no power—though many were still technically operational. Japanese utilities are importing natural gas and oil to satisfy electricity demand.
In June, the French prime minister introduced a bill that would cap nuclear at its current capacity.
Russia has aggressively pursued nuclear power, following a post-Chernobyl hiatus that lasted more than a decade.
