New LED light bulbs cost $15, still too expensive
Lighting Science Group and Dixon Technologies today unveiled a new energy-efficient light bulb that uses light-emitting diodes (LEDs) priced for less than $15.
That brings LED lighting, which is much more efficient than typical incandescent lights, slightly closer to commercial viability. LED lights typically costs around $18 per kilolumen of light produced, while incandescent bulbs are around $2.20 per kilolumen. LED lighting bulbs probably won’t reach that point until 2015, Lux Research analyst Murray McCutcheon … Continue Reading
Phillips Lighting CEO: Super-efficient light bulb prices will be cut in half by 2017
The cost of light bulbs that use light-emitting diodes (LED), which are much more efficient than typical incandescent light bulbs, could fall by as much as 50 percent by 2017, said Phillips Lighting chief executive Zia Eftekhar.
LED light bulbs haven’t taken off yet because the price tag per LED bulb can be as high as $50. But the latest generation of light bulbs can generate as much light as a 100-watt incandescent bulb using … Continue Reading

Inside the race to green data centers
When one thinks of green, the first thought that comes to mind probably is not a chilly warehouse packed sky-high with servers. Yet in the energy-efficiency world, that’s exactly what where an increasingly amount of focus is going to — data centers.
Data centers are used by companies to store Web servers and associated computer equipment. And the behemoth buildings, which typically take up hundreds of thousands of square feet, are huge energy hogs, requiring … Continue Reading

On the GreenBeat: GRC cools servers with oil bath, the government as a cleantech VC
Startup Green Revolution Cooling has landed the first customer for its server cooling system that reduces server temperatures by way of an oil bath. Midas Networks is the first customer to be trying the cooling system out. The reasoning behind the system is that liquid can hold and transfer more heat than air. GRC says its oil mixture can cut data center power consumption by 45 percent. The Register has a video here.
