CFLs (Compact Fluorescent Lights) are not all they are cracked up to be. Because of certain technical reasons [pdf] they may cut your power use by a factor of four for a given light output but the power company only sees a power of two reduction on their demand. In other words the power companies have to supply power that is not charged to the users. Guess what? Electrical rates will have to go up to compensate. There is also a further technical discussion available. It is possible to fix this problem with more expensive circuits. Look for Congress' new mandate for light manufacturers, as soon as the electric company guys whisper in their ear. This is not a bad thing. Except that Congress has outlawed cheap tungsten lamps even where their low usage, no phantom (reactive) power, and low cost would make sense. Big Brother only has your best interests at heart. Just ask him.
