Lester Brown, head of the Earth Policy Institute, a nonprofit environmental think-tank that I support, gathers interesting statistics & news on the upsides of switching from incandescent to compact fluorescent light bulbs in his latest Earth Policy News Update.
While I find the idea banning of incandescents (or of any non-hazardous item) obnoxiously heavy-handed, I do support providing incentives to switch to compact fluorescents or LEDs to save energy & reduce the emission of global warming gases. I think that a CO2 tax or cap & trade limits on greenhouse gas emissions which raise energy prices are the less intrusive & more far-reaching ways to move the market toward more efficient alternatives, both in lighting & other sectors, points that Lester argues in his (freely available) books Eco-Economy & Plan B 2.0.
