[The planned Yahoo] data center will be powered mainly by hydroelectric power from Niagara Falls, with 90 percent of that energy going towards powering the servers. The center itself will be built to resemble a chicken coop, using 100 percent outside air to cool the servers, a task which typically gobbles up 50 percent of a data center’s energy supply.

I’m interested in Louis Proyect’s ideas about left organizing as well, Bob. The US Solidarity org, Canada’s New Socialist Group and France’s New Anticapitalist Party are other interesting examples in my opinion.

It’s a serious 3.2 mile uphill hike through a mountain pass to get to the top of Upper Yosemite Falls. Mountain miles are way different from flatland miles. It took me 6 hours of hiking time, round trip. There were lots of ill-prepared people in sneakers carrying a pint of water trying the hike, and plenty of people hobbling down the trail.

It’s 8.2 x 12.6 feet, with two beds upstairs, and a kitchen, bathroom, living room. and solar power.

Jetson Green has all the details.

Giant sequoias are hard to photograph because they are so huge. These two photos show the enormous scale of these trees.

Many people have the misconception that the renewable energy field is comprised largely of little start-ups. In reality, many of the heavy hitters in the industry are large, established companies, such as General Electric, Google, and Waste Management.

Indeed. GE is huge in wind power, Google is investing heavily in renewables, and Waste Management plans to turn massive amounts of garbage into syngas.

Not only do such big corporations have the money and resources to fund cleantech, they are also demonstrating to other companies how to do it. This is important, because without them on our side, the change isn’t going to happen. And clearly, many of them now do see the virtues (and profit-making possibilities) of cleantech and renewable energy.

We don’t know. But trying to run for higher office after resigning a governorship with no explanation seems a dead end to me.

This is deliberate policy too, done to save money. Clearly, such insurance companies can little or nothing about the health of those they insure.

Canopy rafts are dropped from the air. Researchers are able to spend days in them studying the tops of rain forests.
