Lucas123 writes "The very thought of losing that pear-shaped giver of warm, yellow light drove Europeans to hoard Edison's invention [Note: Or possibly Joseph Swan's invention; HT to eldavojohn.] as the EU's Sept. 1 ban on incandescent light bulbs approached. China's ban on incandescent lamps starts Oct. 1. And, in the U.S., the Energy Independence and Security Act (EISA) of 2007 effectively began banning the 100W bulb this year and will ban the most popular bulbs — the 75W, 60W and 40W screw-in incandescent bulbs --over the next two years. The end standard requires bulbs to use 65% less energy by 2020. But Republicans in Congress continue to fight the ban by hamstringing the energy efficiency standards through appropriations legislation, cutting off funds for the enforcement of the light bulb ban."
