ZigBee’s Green Power spec allows freedom from battery and grid

All good habits begin from home. So instead of blaming the government and other citizens of this planet for abusing energy consumption, why not equip our own den with ZigBee’s Green Power spec. The company is rolling out an energy-harvesting specification that would enable switches and sensors equipped with its wireless home-control technology to operate without batteries and without a connection to a home’s power lines. This means that ZigBee-enabled on-wall light switches, dimmers, motion detector, moisture sensors and door sensors will be able to harvest energy from small solar cells, from heat or from the conversion of mechanical energy to electrical energy. To make it simpler, let me explain to you with an example. To put on light, we press a button. This action will be converted into a small electrical charge, which in turn would power an embedded ZigBee transmitter. And the ZigBee signal would then turn on ZigBee-equipped lights.
