GE has just introduced new incandescent light bulbs that supposedly match the new compact fluorescent type in efficiency and energy savings.
See this post from the Green Tech blog on this announcement. I agree with some of the comments that this appears to be taking two steps back, one step forward, but if the energy savings (and consequent reduction in carbon dioxide) rival fluorescents -- and the prices are right -- then we are still far better off going with either option than doing nothing at all.
Also of note, check out a new Yahoo! site -- 18seconds.org -- designed to encourage people to change to compact fluorescent bulbs -- a task that supposedly takes 18 seconds. The site, sponsored by Wal-Mart, shows a running tally of dollars saved and amount of carbon dioxide reduced as a result of replaced bulbs.
