Change a Light Bulb: It Really Can Make a Difference


According to a new report published by the International Energy Agency (IEA), TreeHugger has been right to promote the use of compact fluorescent (here, here and here as well) and other energy-efficient lighting: a global switch to efficient lighting systems would trim the world's electricity bill by nearly one-tenth. The carbon dioxide emissions saved by such a switch would, it concludes, dwarf cuts so far achieved by adopting wind and solar power. Wow. According to Paul Waide, a senior policy analyst with the IEA and one of the report's authors, "19% of global electricity generation is taken for lighting -- that's more than is produced by hydro or nuclear stations, and about the same that's produced from natural gas." For the individual TreeHugger, the report concludes that the easiest, most obvious switch to make is from incandescent bulbs to compact fluorescent systems, and to watch out for the LED revolution, just around the lighting corner. ::BBC News via ::Gristmill
