Welcome! I've always hated "How-To" guides which don't explain why a certain tip works, or how well it works. Sometimes a topic is just as mysterious after you read the guide.  
So my guide on Saving Electricity gives you a bit more than you might get elsewhere. I explain exactly what a kilowatt hour is and how much you pay for one. And I show you how to calculate exactly how much electricity your household appliances use, so you know which items are guzzling the most juice (and which ones are the best targets for savings). You'll learn exactly how to read your electric meter. (Find that on any other website!) Finally, I not only give you meaningful tips for slashing your electricity consumption, I give you the tools to figure out exactly how much you're saving as well. For the hard-core energy misers, there's even an advanced (and optional) section on transformers, as well as exercises to pique your interest.  
This is an EXTREMELY informative guide! While researching energy consumption for my future openMosix cluster, I ran across the Computers section here. Looks like computers don't use much electricity after all.
