iPod inventor’s next trick: a smart thermostat

I've said before that the next Steve Jobs would be in energy, not in information technology, but I had no idea that day would arrive quite so soon. As filmmaker and design critic John Pavlus reports at Fast Company, Tony Fadell, who invented the iPod, is working on a thermostat as intuitive and potentially revolutionary as … […]

Energy prices haven’t budged in 50 years — but oil is crazy expensive

Americans pay about the same as they did in 1960 for most forms of energy, says this infographic produced by the home energy audit folks at WellHome. Except for oil, which is now on average even more crazy-expensive than it was during the oil crisis of the 1970's, when people were ready to bash each […]

Carbon-eating paint could clean air and strengthen buildings

Okay, now this one really sounds fake: Scientists are working on a carbon-eating paint, which would be capable of turning emissions into limestone. In other words, it would let buildings eat carbon and then use that fuel to grow, like a living thing. The secret is synthetic chemicals that behave like microorganisms. Their creator calls […]

China pours money into smart grid technology

Cross-posted from Center for American Progress. There is no way to get around this fact — China aims to modernize its energy infrastructure at home and dominate clean energy technology markets abroad. At the 2011 Smart Grid World Forum in Beijing late last month, China’s State Grid Corporation announced plans to invest $250 billion in […]

Solar airship is most efficient way to fly, ever

How can you carry huge amounts of cargo thousands of miles with no fuel and no infrastructure? By combining an airship with an airplane, of course. The resulting wing-shaped blimp requires less helium than a conventional dirigible, but has a shorter takeoff than an airplane. Hybrid Air Vehicles has been proposing this for years, but upstart […]

Why are all the ‘most efficient states’ blue states?

    This year's list of the top 10 most energy-efficient states looks an awful lot like the map of red and blue states from the 2008 election. (Data were compiled by the American Council for an Energy-Efficient Economy.) We're not sure why. Got an opinion? Share it in the comments.

Solyndra, schmolyndra: The Obama administration’s hit rate is better than the private market’s

Making loans is a tricky business — sometimes you bet on the wrong horse. For example, there's the Obama administration, which doled out 1.4 percent of its Recovery Act cleantech investments to failed solar company Solyndra, in a move that everyone and their uncle is now calling a giant embarrassment. And then there's private venture […]

Who you gonna call? GrowthBusters! [VIDEO]

The new documentary "GrowthBusters: Hooked on Growth" explores why our economy and footprint and population can't keep on expanding forever.

Electric vehicles improve fuel economy even if people don’t buy them

The first version of a radical new technology always gets off to a slow start -- remember what they said about the first iPhone? -- and so it is with the all-electric Nissan Leaf and plug-in hybrid Chevy Volt. Yet both vehicles are having an unexpected effect on their makers' bottom line. By getting people into the showroom, they’re helping to move other fuel efficient vehicles.

California adopts nation's first state cap-and-trade program

In what the L.A. Times calls "landmark" legislation, on Thursday California became the first state in the nation to adopt a classic cap-and-trade system for regulating greenhouse-gas emissions.

Cap-and-trade is the centerpiece of AB 32, California's historic climate change law that mandates a reduction in carbon pollution to 1990 levels by 2020. Beginning in 2013 the state's largest carbon emitters will be required to meet the caps or buy credits if they cannot.
