Since my home does not run on solar power, the use of unneeded electricity is not something I like. I went around the house and realized that I still had many incandescent bulbs still in use. I replaced them with some CFLs I already had, and I started to get LED bulbs too. Now I won't get anything but LED in the future. A lot of people don't want to get them because they are a tad more expensive (but not as bad as they used to be) at first, but they can last about two decades and use less energy than even CFLs. They are certainly are the light bulb of the future.
Does your house still use energy-inefficient light bulbs?
