Onzo energy display and sensor

Time for a home energy dashboard?

To save energy at home, one of the first things you can do is start measuring your consumption. With more detailed information than a monthly bill, consumers can change their behavior and shave between 5 and 15 percent off their bills, say experts.

Analysts project that millions of home energy displays will be installed in the next two to three years, largely through utilities' smart grid programs. This image gallery will show you some of the different approaches, using both hardware and software, to home energy management from the dozens of companies in the field.

This energy display is from Onzo, which plans to release the device in the U.K. next year. The device is coupled with a sensor that can read energy usage from a home's wiring. The wireless display will show real-time energy usage, historical data and provide access to Web services.
