Ladyada’s project involving Microcontroller, XBEE wireless module is used to monitor the power used up at homes using the wireless module. Ladyada provides you the Kit, the Project Design and the Software to monitor the power used. Apart form the basic software to receive the input from the wireless XBEE module, it also provides you with the codes for storing this date and viewing it in the forms of graphs. The project can be found at the link provided below.

The project is further extended to Tweet the power used up at homes. The whole setup would cost you less than $55. Though this might not fit-in for a Final Year Project or a College Project, this sure would work out for a Mini-Project or School Projects.
The documentation at the link provide above give you the codes and the components that you need for developing this product.

This is a very interesting. It would be great to learn what areas you could cut power done to save some bucks. People would do a lot more with power saving if they werent scared of getting electrocuted.
