"Two hours ago I lost a $3 million building," he declared to the room. "And now I don't have a place to live."
In a recent CNN commentary entitled "Green jobs: hope or hype?" Samuel Sherraden argues that green job creation will be insufficient to bring America out of recession. But Sherraden narrowly defines green as a "sector," and fails to see its potential as a strategy for the revitalization of the entire economy.

When companies as savvy and as important as General Electric and Google join forces, it's worth a closer look. The companies say they will work together to drive two industries with big growth potential: geothermal energy and the upgrading of the nation's overburdened electricity grid.
While politicians of all stripes are vying to be seen as saviors in the energy crisis, Congress isn't giving renewable energy investors the one thing they say would help the most - long-term tax credits.
It looks like a scene from an old episode of The X-Files: As a red-tailed hawk circles overhead and a wild pronghorn sheep grazes in the distance, a dozen people in dark sunglasses move methodically through a vast field of golden barley, eyes fixed to the ground, GPS devices in hand. They're searching for bodies.

Doug Buchanan grins with relief when he sees the carcasses. He has just driven up a steep dirt road onto a vast, sunbaked mesa overlooking the Mojave Desert in western Nevada. There, a few feet from the trail, lie the corpses of two steers. A raven perches on one, the only object more than three feet above the ground on this pancake-flat plateau. Cattle, dead or alive, qualify as good news in Buchanan's line of work. If cattle are present, that means grazing is permitted, and that in turn means that this land is most likely not protected habitat for the desert tortoise.
Billionaire oilman T. Boone Pickens is putting his clout behind renewable energy sources like wind power.

Everybody talks about global warming and high gasoline prices, but who, really, is doing anything about it? Entrepreneurs, that's who. In my upcoming book, The Plot to Save the Planet, I chronicle the small-business owners who are creating the green houses, cars, and energy sources that will slash our fuel bills and help clean up our ecosystem. For the first time, big money is available to back their efforts. In 2007, venture capitalists invested $5.2 billion in green tech, up 44% from the previous year. Meet mavericks who are working on creative (and potentially lucrative) solutions to our energy challenges.

Steve Vassallo spends his days looking for the next Steve Jobs. Not for the computer industry, it has its already, but for the clean-tech world in which Vassallo, a venture capitalist, invests. "I haven't found him or her yet," says Vassallo, a principal with Silicon Valley-based Foundation Capital. "They are probably still in their cubicles some place doing their IT job, or in a garage with an idea."
Curt Mann's neighbors are livid, accusing him of erecting an ugly wind turbine among their historic homes for no other reason than to show off his environmental "bling."
