I’ve switched out 15 lightbulbs (which is fewer than I originally pledged, but I don’t have any more burnt out bulbs in the house right now, and we’re moving soon). Once we’re in a new place permanently, I’ll make a new pledge. Plus, I’ve posted about this to my LiveJournal, to encourage others to participate.
And if you haven’t yet participated, *nudgenudge* here is the link again, to the Million Bulb Swap Out campaign! Fight global warming one bulb at a time!
