Micro wind turbines are beginning to pop up all over our urban and rural landscapes. But is it worth investing your hard-earned cash in your very own wind machine? In short, it depends. Take a look at our quick guide to see if "small wind" could help you reduce your energy bills and your carbon footprint.
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.
Twenty four hours before the greatest scientific experiment of our time gets underway at CERN's Large Hadron Collider, political and scientific dignitaries assembled at a site a few hundred miles north east of the French/Swiss border at a site in Germany to inaugurate another groundbreaking engineering test.
If there was a most wanted list for climate change culprits, coal-fired power stations would be number one.
The site has been secured, the tents pitched, banners raised and, most importantly, compost loos installed; there is little to do now but wait for thousands of campers to arrive for one of Britain's biggest environmental protests this year.
A government-controlled firm is forging ahead with plans to resume expansion of Brazil's nuclear power program.
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.
Texas oil man T. Boone Pickens Tuesday unveiled a new energy plan he says will decrease the United States' dependency on foreign oil by more than one-third and help shift American energy production toward renewable natural resources like wind power.
Plans to rejuvenate a dilapidated London icon -- known worldwide to movie and music fans -- were unveiled last week.

Since it became a viable energy resource around 20 years ago, wind power has emerged as a leading renewable technology.
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.
Of all the power supplies in the energy mix, nuclear has historically been the most criticized and controversial. But this most unpopular of power sources has recently resurfaced in political and economic dialogue.
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.

Coal is almost the perfect fuel. It's cheap and absurdly abundant -- especially in the United States, which has the world's larges reserves. There's just that tiny problem of massive climate-altering carbon dioxide emissions. Or is there?
Widespread anxiety about the damaging effects of burning fossil fuels, coupled with a genuine fear that oil and gas will become scarce before the century ends are fueling a renewed interest in renewable energy and, in particular, solar power solutions.
Environmental author Alan Weisman has fielded questions exclusively from CNN.com users on the environmental matters that concern you most. These are his answers.
A typical exchange about wind farms tends to go like this: 'Are you in favor of wind farms?' 'Yes, of course I am...so long as they're nowhere near my house'. Nevertheless, wind turbines are fast-becoming an important piece in the energy puzzle, contributing a growing percentage to our overall energy needs.

James Bond would be lost without them -- those madcap gadgets merging two technologies that help him beat the bad guys and save the planet. The underwater watch with a built-in Geiger counter, for example; or the car that doubles as a submarine; or the exploding bagpipes and missile-launching wheelchair.
One thing I've learned on my 7,000 mile journey through America's nuclear past and present is that when you're driving around scouting for a power plant -- any kind of power plant -- first locate the high-voltage transmission lines. (If you stand directly under those lines, sometimes you can hear the electricity cackle and spatter like rain drops on the roof.)

Nuclear power plants will not be required to put up defenses against terrorist attacks from the air, according to a rule enacted Monday by the Nuclear Regulatory Commission.
The background: Carbon dioxide makes up nearly 80 percent of all greenhouse gases. More than a quarter of that CO2 comes from electrical power plants. That's why replacing plants that run on fossil fuels like coal, oil, and natural gas with renewable power sources, even nukes, has emerged as a major plank in the campaign against global warming.
If you wanted to choose the perfect location for capturing the ocean's energy, you couldn't do much better than the Oregon coast. Waves arrive there with immense power, having traveled across thousands of miles of open water with few barrier islands, reefs or other obstructions to slow them down.
ExxonMobil delivered its annual long term energy forecast Tuesday, saying that it expects the world will use 60% more energy in 2030 than in did in 2000. But despite this spike in demand, the oil giant does not expect to see any increase in the use of renewable energy sources from 2006 levels.
