How much energy do you consume?

A system, developed by engineering students at Northeastern University, can help cut your energy bills.

The system, called Empower Numbers (numbersempower.com), uses wireless sensors to monitor each appliance in your home individually.

It also allows the devices to shut off from any location with a mobile phone or PC.
