Google drops ‘Renewable Energy Cheaper than Coal’ research project


Did Google give up on the planet?

Google is quite a big proponent of renewable energy. They have made all kinds of investments in wind, solar, geothermal, etc. Some are to generate clean energy for their own needs, others are more akin to financing deals to help big wind and solar farms get built. In any case, it is very commendable work and if more big corporations had the long-term vision of Google, the world would definitely be in better shape.

But sadly, one of their most promising clean energy projects has just gotten the axe. Renewable Energy Cheaper Than Coal which was launched in 2007 via the Foundation, aimed to drive down the cost of renewable energy via R&D efforts until it was cheaper than coal, the magic point at which adoption would reach escape velocity…

Study: Energy efficiency of computers doubling every 18 months


Computers are getting more efficient every day.

Those of us fighting the battle with computer batteries will appreciate this. Batteries have come a long way since the 1990s. For instance, if a MacBook Air were as efficient today as a 1991 computer, the battery would last for 2.5 seconds. In other words, it would be dead by the time you got to the end of this sentence. The Atlantic has the story. And it’s bound to fan the flames of the PC v. Mac wars.

Flames also would refer to how quickly some PC batteries seem to burn out, compared to their Mac counterparts. I know, PCs are getting better. Don’t get me wrong. But Macs have lead the battery longevity pack for some time…

China to Shut Down 2,000 Factories to Meet Their Energy-Efficiency Goals


Coal has made China the world’s largest emitter of greenhouse gases.

Earlier this summer, Prime Minister Wen Jiabao of China promised to use an “iron hand” to improve his country’s energy efficiency, and a growing number of businesses are now discovering that it feels like a fist.  The Ministry of Industry and Information Technology quietly published a list late Sunday of 2,087 steel mills, cement works and other energy-intensive factories required to close by Sept. 30.
