Part of "going green" means monitoring your energy output, a task now made infinitely easier with the introduction of the Onzo from the UK. The kit is composed of a display that shows your current consumption and sends that information wirelessly to a sensor unit.

The device can store up to ten years of information and also offers a USB connection to your home PC. Although the design is final, the company has yet to firm up a price for the product that is scheduled to go into production later this year.
