Sprouts of Hope Kids is a local group that has organized the company that makes them to donate 20 Kill-a-watt meters to the Cambridge Public Library so that you can borrow one (for a week) and measure your energy usage, to see if something you have is sucking huge amounts of energy out of your life. :-)
And you can borrow stuff from the Cambridge library if you have a Somerville Library card (both are on the Minuteman Network).
And it looks like you can request an inter-library loan and have it delivered to the closest Somerville Library branch (for example, the one in Davis Square...) if you want. (It's listed as the "Kill A Watt : electricity usage monitor" on the Cambridge library list, which doesn't have a waiting list like some of the other libraries have for the item.)
