I bet you have quite a lot of those. Even if not, the CFLs you'll have to give you light at night still draw much much more than a computer. If saving energy is your personal driver, then you should be looking at water heaters, central heaters, aircon and stove as the main culprits. Everything else, whilst measurable, is a small drop in the bucket and probably not worth worrying about. Assuming of course that your computer is a desktop/laptop, and not a 42U cabinet jam packed full of Dell 2950s -- Alan McKinnon alan.mckinnon@gmail.com
