We are about a year away from the date on which mandated energy efficiency standards will increasingly make it impossible to sell incandescent bulbs in the U.S. For my part, I hope LED-based lighting is a cheap alternative to ordinary household incandescent by then. Compact fluorescent lights, despite a lot of hype, just don't seem to have lived up to the energy efficiency promises of their promoters. READ MORE
Residents of the Scottish town called Invergordon are about to witness the first sea trials of a power-generating bouy device called, aptly enough, the PowerBuoy PB150. Developed by Ocean Power Technologies, Inc., the new generator has a capacity of 150 kW. It creators foresee ocean-based farms full of the devices that will generate hundreds of megawatts. READ MORE

The rules of the game for Energy Star changed on January 1. Now products bearing the Energy Star designation need certification from third-party labs. New third-party certification procedures require manufacturers seeking use of the Energy Star label to conduct testing in EPA-approved and accredited laboratories. But what happens when a company cannot rise to meet the newest Energy Star certification procedures enforced by EPA? READ MORE
A start-up called Ideal Power Converters in Austin, Tex. says it recently flipped the on-switch for a test of its prototype 30 kW commercial-scale PV inverter. The device's claim to fame is its small form factor and elimination of magnetic components ordinarily required for switch-mode power supply topologies. READ MORE
