There's a monitor being developed by some doctoral candidates in Japan that takes TED further; it's a really cool interactive device. Hopefully it will be fully developed and become available here (but I think that would be years from now).
Sorry for the big pic, but I want it to be legible. (I love that "rice cooker" is in the list of appliances.)
There was also a presentation on TED. Most people really liked it at first; they checked their usage all the time for the first couple of weeks, but then they pretty much ignored it after the novelty wore off. I'd stick with the energy meters you can check out from the library.
