What goes on at night?
Having an electricity monitor, either a Web application or hardware display, is a regular reminder of your electricity use and should help you find ways to save energy. In testing this particular one for a few days, I found that it prompts you to try to find out more, such as how much one device uses, or what is the energy-cycle pattern for appliances.
