Get an education on EVs

Those attending our second annual education day in San Jose this week will get an up-close and personal look at the E.Rex, which will be at the event, and hear about this EV's power management scheme from keynote speaker Mike Worry. There are a host of other speakers as well. Check out the proceedings here. Send us your energy efficiency news at [email protected] -- Leland Teschler, Editor

LED bulb replaces 75-W incandescent

Just in time for the U.S. phase-out of incandescent bulbs comes the Philips EnduraLED A21, a 17-W LED-based bulb billed as a replacement for conventional 75-W incandescent bulbs. Developed by Royal Philips Electronics, the bulbs use the company's high-power, next-generation Luxeon LEDs. READ MORE
