One way to save energy is to be fully aware of how much you’re using. That’s the mission of The Energy Detective 5000, otherwise known as TED 5000. Connect a couple of sensors to your main power switch box, plug the powerline gateway into an electrical outlet, connect it to your network, and suddenly you can access a graphical interface showing you exactly how many kilowatts you’re using over days, weeks and months. We hooked up the TED 5000 in our Midwest Test Facility, and it turns out we’re not using as much energy as we thought.
