Time to check the juice
Here is EnergyHub's dashboard, which is being tested at three utilities in the U.S. The small display gives people a way to quickly see how much electricity they are using at a given time. By giving people regular information on their usage, they can cut electricity use between 5 and 15 percent, according to studies.
EnergyHub's system is being used in conjunction with smart meters in its initial trials, but energy information can also be gathered by creating a wireless home-area network. The display has a Zigbee wireless chip that can communicate with a networked thermostat and smart plugs (see on left). That network also allows people to program appliances and ratchet down energy use as part of demand-response programs run by utilities. EnergyHub is selling its products through utilities initially, but it expects the retail cost to be about $250 for the display and thermostat and $35 for Zigbee-enabled plugs.
