In my Twitter stream today I saw a message about Google's PowerMeter. I assumed it had something to do with computer applications (after all, it was from Google), but was surprised when I saw that this was a tool to measure electricity usage. From the Google PowerMeter website -
Google PowerMeter is a free electricity usage monitoring tool that provides you with information on how much energy your home is consuming. Google PowerMeter receives information from utility smart meters and in-home energy management devices and visualizes this information for you on iGoogle (your personalized Google homepage). And, Google PowerMeter is free.
This would seem to be an interesting tool/concept to discuss with students in context of housing and energy usage. It will be interesting to see how this evolves along with other smart house technology.
