A fuel station producing enough hydrogen to run householders' homes and cars has been unveiled today. The British invention, due to go on sale within two years, is roughly the size of a heating boiler and will cost under £2,000. Its creators say it will revolutionise commuting, help homeowners slash energy bills, and give easy access to a fuel that does not produce carbon dioxide emissions, helping to combat climate change.

So far, CNG vehicles haven't made a blip on my radar screen, even though the group Natural Gas Vehicles for America (NGVA) estimates there are 150,000 NGVs on U.S. roads today and over 5 million worldwide. It took a phone call from sunny Southern Utah to clue me in to recent developments, which include a local refueling station overflowing with CNG-hungry vehicles. There are about 1500 CNG refueling stations in the US, which is about the same number of commercial stations offering E85 ethanol blends. Utah has a total of 91 CNG filling stations, most of which are reserved for commercial fleet use, but there are 20 open to the public. According to an article by the Associated Press, you could drive Utah from top to bottom and hit 22 different stations offering compressed natural gas.

T. Boone Pickens is a billionaire oil man and a career corporate raider who loves George Bush so much he donated $250,000 to his 2004 inaugural ball. He was, and still is, fully behind the invasion and occupation of Iraq and makes no bones about it. So why is he now pushing for the use of alternative energy sources like wind and solar in his Pickens Plan?

Use the right energy for the right use. That concept lies at the core of a U.S. domestic energy plan unveiled Tuesday by legendary oilman T. Boone Pickens. The United States uses close to $700 billion in foreign energy supplies, primarily oil, Pickens pointed out on CNBC's "Squawk Box." It will be impossible for one energy source to totally replace that supply, he noted.

A leading U.S. Senate Democrat accused the Bush administration on Tuesday of a "cover-up" aimed at stopping the Environmental Protection Agency from tackling greenhouse emissions. "This cover-up is being directed from the White House and the office of the vice president," said Sen. Barbara Boxer, the California Democrat who chairs the Senate Environment and Public Works Committee.

JUST three years ago, with oil trading at a seemingly frothy $66 a barrel, David J. O'Reilly made what many experts considered a risky bet. Outmaneuvering Chinese bidders and ignoring critics who said he overpaid, Mr. O'Reilly, the chief executive of Chevron, forked over $18 billion to buy Unocal, a giant whose riches date back to oil fields made famous in the film "There Will Be Blood."

The jury is still out on whether hydrogen will ultimately be our environmental savior, replacing the fossil fuels responsible for global warming and various nagging forms of pollution. Two main hurdles stand in the way of mass production and widespread consumer adoption of hydrogen "fuel cell" vehicles: the still high cost of producing fuel cells, and the lack of a hydrogen refueling network.

EAST AMWELL, N.J.-Mike Strizki has not paid an electric, oil or gas bill-nor has he spent a nickel to fill up his Mercury Sable-in nearly two years. Instead, the 51-year-old civil engineer makes all the fuel he needs using a system he built in the capacious garage of his home, which employs photovoltaic (PV) panels to turn sunlight into electricity that is harnessed in turn to extract hydrogen from tap water.

At first glance, they look like a couple of giant inflatable garden chairs that have washed out to sea But they are, apparently, the ultimate solution to rapidly rising sea levels. This computer-generated image shows two floating cities, each with enough room for 50,000 inhabitants.

AFS Trinity Power has developed patent-pending technology that makes it possible for plug-in hybrid electric vehicles to achieve 150 MPG, go 40 miles in all-electric mode, and use gasoline for additional unlimited miles in hybrid mode. In July 2007, in order to very quickly demonstrate all of the key attributes of this technology, the company mounted an effort to build two fully operational XH-150 SUV prototypes using off-the-shelf components. The two vehicles-modified Saturn Vue SUVs-were built in less than six months. They were unveiled on January 13, 2008 at the North American International Auto Show in Detroit (Press Announcement) and (Salon.com test drive report).

With gas prices going through the roof and regulators requiring cars to be ever more miserly, Volkswagen is bringing new meaning to the term "fuel efficiency" with a bullet-shaped microcar that gets a stunning 282 235 mpg. Volkswagen's had its super-thrifty One-Liter Car concept vehicle -- so named because that's how much fuel it needs to go 100 kilometers -- stashed away for six years. The body's made of carbon fiber to minimize weight (the entire car weighs just 660 pounds) and company execs didn't expect the material to become cheap enough to produce the car until 2012.

The White House is currently blocking the Environmental Protection Agency (EPA) from complying with a 2007 Supreme Court ruling that directed the agency to develop global warming pollution regulations under the Clean Air Act. Below is a statement by Brendan Bell, a Washington representative with the Union of Concerned Scientists:

Innovative concept could make wave energy more affordable A device consisting of a giant rubber tube may hold the key to producing affordable electricity from the energy in sea waves. Invented in the UK, the 'Anaconda' is a totally innovative wave energy concept. Its ultra-simple design means it would be cheap to manufacture and maintain, enabling it to produce clean electricity at lower cost than other types of wave energy converter. Cost has been a key barrier to deployment of such converters to date.
