Washington Post: American advances, particularly in green technology, may not necessarily mean more manufacturing jobs for Americans. Because Congress voted to ban incandescent light bulbs by 2014, the factories making them have been forced to shut down, with the last major GE factory in the US closing later this month. Although the savings in energy and greenhouse-gas emissions from changing bulbs may be immense, the manufacture of their replacement—compact fluorescent lamps—has moved almost entirely overseas, mostly to China, because the CFLs’ glass tubes require so much more hand labor, which is cheaper there.
