For a while, I have been thinking about buying a Kill-a-Watt electrical meter, in order to test how much is used by various household appliances and electronics. The problem is, it doesn’t make hugely much sense to spend $30 to $50 on a device that you only really need to use once. As such, I was happy to discover that the Ottawa Public Library system actually has 142 of them available to be borrowed for free. There seem to be at least a few at every branch.
I plan to pick one up sometime this week and test the power usage of my computer, stereo, microwave, etc. I don’t think it will work with my washer or dryer, unfortunately.
[Update: 6 May 2009] I picked up a library Kill-a-Watt tonight, one week loan, no fuss, no deposit. I will post data when I have collected it.
