Suppose my power company claims that the charge is $0.02407 per killowatt/hour. If I have a computer (or anything) that draws maybe 100 watts. that should be 0.1kw/h x 0.02407 x 24 hours = 5.7768 cents per day or $1.73 a month. I've been under the impression for quite some time that it costs $20 a month to run a typical modern desktop computer 24 hours a day for a month. I know there are taxes and fees thrown into the power bill. But what's wrong with my math? Was I wrong before or am I wrong now? I got this kw/h price from the power company web site burried in a pdf somewhere. It looked like the right price to me. Maybe the actual charge is much higher? brian No virus found in this incoming message. Checked by AVG - www.avg.com Version: 9.0.733 / Virus Database: 271.1.1/2736 - Release Date: 03/11/10 02:33:00
