Google last year introduced PowerMeter, a Web-based application for tracking home energy use. The idea is that by viewing daily and historical data, people will find ways to curb energy use. For example, running a pool pump fewer hours a day or at off-peak times can cut bills significantly.
Google is making PowerMeter available through utilities that are installing two-way smart meters in their smart-grid programs. But it is also making the software available through other devices that can gather energy usage data in real time. The first energy display that PowerMeter works with is called The Energy Detective, which can read data by attaching a sensor onto wires in a circuit box. It's recommended that people get an electrician to do the installation, or do it themselves if they are comfortable removing a circuit box cover, the company says.
