Automakers such as GM, Honda Motor Co. and BMW AG are putting several hundred hydrogen vehicles into suburban garages, in cities and on the highway to see how they fare in day-to-day drivin
It's an annual ritual on Wall Street - the fourth quarter IPO season, when a flurry of companies make their debut on the public markets before New Year's. But given today's volatile market, and the dismal performance this month of what seemed sure to be a no-brainer IPO in Rackspace, you have to wonder what kind of year-end bump we might get.
New York's famous skyline may be getting a new addition: Wind turbines.
Viewpoint: John McCain says the U.S. should drill untapped natural gas and oil. Here's another thought: Mine the country's far larger reserves of alternative energy

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.
U.S. House Speaker Nancy Pelosi on Tuesday urged President Bush to release crude oil from the nation's Strategic Petroleum Reserve to combat high prices, a call Republicans used to bolster their push to increase domestic production with more drilling in environmentally sensitive areas.
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.

Meet mavericks who are working on creative (and potentially lucrative) solutions to our energy challenges.
North Korea is to blow up a key part of its controversial Yongbyon nuclear reactor on Friday.

Billionaire oilman T. Boone Pickens is sinking billions of dollars into a new wind farm in Texas. It is likely to become the biggest in the world, producing enough power for the equivalent of 1.3 million homes. CNN's Ali Velshi asked the oil legend why he thinks wind could be the answer to this country's energy problems:
Jyoti is the Hindi word for light. It's something Pranav Mehta has never had to live without. And he is lucky. Near where he lives in Gujarat -- one of the most prosperous states in India -- thousands of rural villages lack electricity or struggle with an intermittent supply at best.
When Goldman Sachs analysts suggested last week that oil could hit $200 a barrel, I expected someone somewhere to express horror at the possibility. But the reaction was a tiny, resignation-filled sigh. Relentless fuel-price increases have so exhausted consumers that we don't have the energy to be outraged anymore. So we feel helpless as we watch oil sprint past the $130 mark on its way to price-prohibitive territory and wonder whether it's too late to bring back the horse and buggy. Our sense of helplessness is an illusion: There are things we can do. We got ourselves into this mess, mostly through multiple administrations of politically comfortable but shortsighted decision-making. And inasmuch as we're willing to stand a little political discomfort, we can get ourselves out.
David Crane is a man who isn't afraid of a challenge. When he took the helm at NRG Energy in the winter of 2003, the company was mired in Chapter 11 bankruptcy proceedings -- just one of many companies caught in the meltdown of the U.S. power generation industry, instigated by the scandalous collapse of Texan power giant Enron in 2001.

Gerri Willis answers reader's questions.
Sandwiched between two nondescript commercial buildings in a vacant lot squats what looks like a long, plastic-shrouded greenhouse. Hanging nearby is a cluster of five-foot-long plastic sacks bulging with green slime that resemble intravenous drip bags for the Jolly Green Giant. It doesn't look like groundbreaking technology, but these scum bags in Cambridge, Mass., just might help save the planet.
Jeff Immelt, chairman and CEO of General Electric, said Monday much of the technology to make energy generation cleaner and more efficient is available now. The challenge, however, is deploying it and making it cheaper.
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."

Texas may be best known for "Big Oil." But the oil that could some day make a dent in the country's use of fossil fuels is small. Microscopic, in fact: algae. Literally and figuratively, this is green fuel.
It sounds like a tall order for a high-tech startup, but Seth Grae's two-man firm in a Washington, D.C., suburb might just save the world from nuclear annihilation.
French President Nicolas Sarkozy and British leader Gordon Brown Thursday called for an early warning system to alert international markets to further turmoil in the wake of recent banking scandals fueled by the U.S. credit crunch.
The clock is chasing down 1 A.M. It's late for dinner - or for interviews - in Almaty, Kazakhstan's former capital. But self-made Kazakh uranium czar Moukhtar Dzhakishev is just hitting his stride. Between spoonfuls of Beluga caviar and bites of ruby-colored tuna flown in from Dubai, he is explaining that his small state-owned company, Kazatomprom, will soon rule the global nuclear energy industry. "I don't think there will be any competitors," he says softly. "I will eat them."
What if you could provide the world with an endless supply of virtually carbon-free electricity; ensure a constant source of drinkable water to the world's most vulnerable areas; avert some of the world's future humanitarian crises; and save billions of dollars in the process? Certain concentrated solar power (CSP) proponents say there is no "could" about it -- it's more a case of "can."
Tree-hugging goes only so far. The modern-day breed of environmentalist has bigger, better, higher-tech solutions for fixing global climate change
As the lighting dims in the auditorium of California's Computer History Museum, a four-foot-tall robot, Asimo, strolls onto the stage. "Hello, Tiffany," Asimo greets its human assistant, in a voice slightly too flat to be human. "It's nice to see you." After a little more chitchat - Asimo, a polite sort, is thrilled to be in San Jose - the robot shows off some tricks. It balances on one foot, kicks a soccer ball, sidesteps in two directions, and climbs up and down stairs. For its final stunt, Asimo jogs around the stage, legs churning and arms pumping, leaving the ground between each stride - just the way a human would.

What is the future for energy? Where will our power come from by 2020? Send us your thoughts and we'll print the best ones here.
The sun, we are frequently told, is the best source of energy there is -- so much so that in just one hour it can provide the earth with all the energy its inhabitants demand in a year. Not only can the sun provide us with all of our energy needs (10,000 times over in fact, according to Greenpeace) but it can also apparently do this without any of those unpleasant side effects that you get from fossil fuels such as air pollution or ozone depletion. And best of all, this resource will never run out -- or at least, not in the next 5 billion years or so.
