Solar co-ops to the rescue

For the average energy or climate geek, the daily open hydrant of news can be a relentlessly depressing and detached mix. It’s all either eye-glazing details about megawatts of electricity and gigatons of CO2 and billions of vehicle miles traveled, or another round of enervating stories about countries finding yet more excuses to do far . . . → Read More: Solar co-ops to the rescue

Nukes gone wild

US nuke regulators weaken safety rules:

Federal regulators have been working closely with the nuclear power industry to keep the nation’s aging reactors operating within safety standards by repeatedly weakening those standards, or simply failing to enforce them, an investigation by The Associated Press has found.

Doc alert: America’s energy challenges

Stephen E. Koonin gave a presentation last October, Addressing America’s Energy Challenges. Koonin is Under Secretary for Science of Energy at the US Dept. of Energy, and he pulled together a lot of information and presented it in an excellent, and sometimes quite enlightening way.

The presentation is available here [36 page PDF].

Desert solar power

When I gave a presentation on the challenges of electricity generation to 10 classes of local middle school students a while back, one of the things I stressed to them was how we were entering an age of localized energy. I didn’t mean generating electricity local to the end users (that’s decentralization, and we’ll see . . . → Read More: Desert solar power
