While individual power monitors can help you track energy lost through phantom power, left-on lights, and leeching appliances, the Powerhouse Dynamics eMonitor centralizes all of your home's energy data.

It tracks information from every outlet, suggests ways to save energy, brings overloaded circuits and too-high loads to your attention, and links it all to your carbon footprint so you can see how turning on that light impacts the Earth.

And that's not all: The monitor even helps you figure out how and where to make the most of renewable energy sources. (Powerhouse Dynamics eMonitor, $670)
