Do you use CFL (compact fluorescent lamps) light bulbs? I do, and have persuaded a few other people to get rid of their incandescents and install them as well.
They use about 25% of the electricity of an incandescent with equivalent light output and have and typically have a life of about 8 years. They pay for themselves in electricity savings in about 4 or 5 months.
Since electric lighting comprises about 20% of an average home's electric bill, installing them will save you 15% on your electric bill. If you live in a warmer climate and use a lot of air conditioning, one could save 25% or more on their electric bill by installing CFL light bulbs.
Prices have come down as well, one can purchase six 100W equivalent CFLs at Wal-Mart for just $15.00. They are made in every wattage one could need, and dimmable varieties are available as well. Improvements in technology and design since their introductions has made them so they come on instantly and they provide the same quality of lighting, in contrast to the lower quality and dimness they had in the past.
As you can probably tell, I'm a big fan, and I'd encourage you to go out and replace your incandescents with CFL bulbs.
If you use CFLs (or LEDs) for most of your lighting, vote yes. Of course you vote yes after your purchase them and install them too.
