Rather than whine about how this community is only used for petitions, I thought I'd post something that might be worthwhile to friends of the environment...


If you can't drive less or don't have the money to weatherize your house, there's an easy (and cheap) way to reduce your carbon footprint and save some money in the process. You just need to replace existing incandescent lights with compact flourescent lights (CFLs).

Walgreens.com sells four sixty-watt incandescents light bulbs (with an output of 600 lumens) for $3.00, or seventy-five cents a bulb. Energyfederation.org has a four pack of CFLs (with an output of 900 lumens) for $11.95, or just under three dollars a bulb. On the surface, it would appear that CFLs are four times as expensive.

But the CFLs have a rated lifetime of 10,000 hours, while the incandescents are rated at only 1,000. By that fact alone, the price is $7.50 per 10,000 incandescent hours, vs. just under three dollars for a CFL. In addition, the CFLs use only 15 watts, compared to 60 watts, so the price to power the bulb is one-quarter what it would be with incandescents. Energyfederation.org claims that at a rate of $0.08 per kWh, the energy savings is $36 per bulb, and the CO2 reduction is 750 lbs. per bulb.

All of those numbers were just for the specific item selected from each website. Your numbers may vary.

This, unlike a lot of other things, is a really easy thing to do. The only caveat is that CFLs are not suitable for some kinds of fixtures, so be sure to read fine print carefully before switching.

I've already replaced the bulbs in my house. Actually, I started replacing the bulbs with the CFLS as the old ones burned out. I have to keep in mind that even though it seems like I'm spending more money on bulbs, they'll last a lot longer in the end, which is not only helping the Earth, but is also saving me a little money at the same time. At least that's how I like to look at it.

Don't forget - you can green and localize your diet. That's one way to hugely change CO2 usage...
