This cool little gadget displays how much electricity is being used within the home. Called the eco-eye, this device shows in Kilowatts the power used and the cost for power per hour, day, week, month or even year. Uniquely, it also displays carbon emissions caused by your energy consumption.
A small sensor fits into your electricity meter which sends power usage information to the main screen unit for display. The unit can either run on rechargeable batteries or an AC adapter. The eco-eye costs £49.99 or about $100 USD.
