Lots of people ask us how much a certain device such as a computer, stereo, television or hot tub costs them to use. We get asked this question so much that we thought it would be helpful to others if we put together a collection of guides explaining how to answer this question for the devices that you want to know about.

Most people who ask this question are interested in reducing their overall power bill. In order to be effective at reducing your power bill, it is important to understand the basics of not only how much power costs, but also roughly how much power a variety of devices use. We also teach you the skills that you need to measure your own devices using a variety of methods.

If watts, kilowatts, and kilowatt hours are new terms to you, then please follow these guides in order. They are short and easy to follow, and it shouldn't take you very long to read them all. Then come back and use them as a reference when calculating your own values.

Lets start at the beginning. What is a Kilowatt Hour? You need to understand this basic unit in order to understand how to reduce your overall power consumption.
