Reduce your carbon footprint and save money...
How cool is that!
PG&G, yes the electric company, is providing instant rebates on select compact fluourescent lightbulbs that make CFLs cheaper than incandescent lightbulbs. For instance I got four 100 W, CFLs for $0.99. No that is not a typo. When CFLs are cheaper than the alternative where's the excuse. To find out retailers who are offering the instant rebate built into the price visit here.
I know that some are going to say that the light isn't as clear or that it takes a few seconds to warm up. I agree, it's a sacrifice. In some fixtures that have two bulbs, I put one CFL and on regular lightbulb. You barely notice the difference when they blend together. Alternative lighting will get better, start on the path now!
