According to ClimateStar.org,
If every family in the US replaced one regular light bulb with an energy saving model, we’d reduce global warming pollution by more than 90 billion pounds, the same as taking 7.5 million cars off the road.
That sounds like a staggering amount of pollution to prevent. Of course, there are a staggering number of families in the US — we’re talking about lots of new bulbs.
I have few wasteful “heat bulbs” left to replace. But I know people who appear to insist on spending 4x as much energy to light their homes. Perhaps for their next birthday they’ll receive a selection of Compact Fluorescent bulbs and a card with the quote above.
(I’ve written before about the color of compact fluorescent lights… information that is relevant for first-time CF buyers.)
