A fungus that lives inside trees in the Patagonian rain forest naturally makes a mix of hydrocarbons that bears a striking resemblance to diesel, biologists announced today. And the fungus can grow on cellulose, a major component of tree trunks, blades of grass and stalks that is the most abundant carbon-based plant material on Earth. "When we looked at the gas analysis, I was flabbergasted," said Gary Strobel, a plant scientist at Montana State University, and the lead author of a paper in Microbiology describing the find. "We were looking at the essence of diesel fuel."

"As fossil fuel prices rise, as oil insecurity deepens, and as concerns about climate change cast a shadow over the future of coal, a new energy economy is emerging in the United States,"� says Lester R. Brown, President of the Earth Policy Institute, in a recent release, "New Energy Economy Emerging in the United States"� . "The old energy economy, fueled by oil, coal, and natural gas, is being replaced by one powered by wind, solar, and geothermal energy. The transition is moving at a pace and on a scale that we could not have imagined even a year ago."�

The U.S. Department of the Interior (DOI) last week announced plans to allow geothermal drilling in more than 190 million acres of federal land, spanning 12 Western states. Dirk Kempthorne, secretary of the interior, said that the proposed initiative could increase geothermal power production in the U.S. tenfold. "Geothermal energy will play a key role in powering America's energy future, and 90 percent of our nation's geothermal resources are found on Federal lands," Kempthorne said. "Facilitating their leasing and development under environmentally sound regulations is crucial to supplying the secure, clean energy American homes and businesses need."

Olive stones can be turned into bioethanol, a renewable fuel that can be produced from plant matter and used as an alternative to petrol or diesel. This gives the olive processing industry an opportunity to make valuable use of 4 million tonnes of waste in olive stones it generates every year and sets a precedent for the recycling of waste products as fuels. Researchers from the Universities of Jaén and Granada in Spain show how this can be achieved in a study published in the latest edition of the Society of Chemical Industry's (SCI) Journal of Chemical Technology & Biotechnology.

In a move that will bring thin-film solar panels to the U.S. residential market, First Solar has signed a deal to provide installer SolarCity with 100 megawatts' worth of solar arrays over the next five years. First Solar is also investing $25 million into SolarCity, the Silicon Valley startup backed by Tesla Motors founder Elon Musk. This is First Solar's initial foray into the home market - and apparently the first of any thin-film solar module maker. Thin-film solar panels are made by depositing solar cells on sheets of glass or flexible material and use little of the expensive silicon that forms the heart of more bulky conventional solar modules. That makes thin-film panels cheaper, although they are less efficient at converting sunlight into electricity. And thin is in for homeowners who prefer less-obtrusive panels on their roofs.

Technology Review has an article on a new system from Ener-G-Rotors which harvests energy from low temperature waste heat - Electricity from Waste Heat. Factories, data centers, power plants--even your clothes dryer--throw off waste heat that could be a useful source of energy. But most existing heat-harvesting technologies are efficient only at temperatures above 150 °C, and much waste heat just isn't that hot. Now Ener-G-Rotors, based in Schenectady, NY, is developing technology that can use heat between 65 and 150 °C.

The ABC recently had a report on plans to power north-west Queensland with low temperature geothermal power using hot water from the Great Artesian Basin. A Brisbane-based company says it could supply geothermal power to all of north-west Queensland. Clean Energy Australasia wants to build a $50 million geothermal power station near Longreach. But it has now also revealed plans to build a pilot geothermal project near BHP's Cannington mine at McKinlay, south of Cloncurry. The company's Joe Reichman says the Mount Isa region needs about 500 megawatts of power a year and geothermal resources could easily provide that. "It'll change the region into a powerhouse," he said. Mr Reichman says the company has applied for federal and state government grants and has support from the major mining companies in the region. If the projects proceed they would be the first geothermal power plants in Australia.

Energy independence is still only a hypothetical goal for the U.S., but the owner of a tiny island off the coast of Connecticut says he has already achieved that feat and is offering his work as a model. Dean Kamen, inventor of the Segway and numerous medical devices, jokingly refers to his North Dumpling Island as an independent nation and himself as Lord Dumpling. Kamen claims to have his own currency and offers visas to visitors to the tiny island a few miles from Mystic, where he is the only resident.

A new kind of silent hero has joined the fight against climate change. Santa Coloma de Gramenet, a gritty, working-class town outside Barcelona, has placed a sea of solar panels atop mausoleums at its cemetery, transforming a place of perpetual rest into one buzzing with renewable energy. Flat, open and sun-drenched land is so scarce in Santa Coloma that the graveyard was just about the only viable spot to move ahead with its solar energy program. The power the 462 panels produces - equivalent to the yearly use by 60 homes - flows into the local energy grid for normal consumption and is one community's odd nod to the fight against global warming.

Check out the video below to see how you can run your car on water.

It was a day when the shift from the past to the future was almost palpable. It started Thursday morning in Berkeley where Green Wombat was moderating a panel of tech luminaries gathered at the University of California's Global Technology Leaders Conference. As Shai Agassi, founder of electric car infrastructure company Better Place, makes the case for harnessing Silicon Valley's technological innovation to Detroit's manufacturing might to create a sustainable car industry, dispatches from the automotive apocalypse roll down my BlackBerry: Ford (F) shares sink to $1.01…GM's (GM) stock falls to its lowest level since World War II…U.S. automakers beg for a bailout…California Congressman Henry Waxman ousts Michigan's John Dingell - the Duke of Detroit - from his 28-year chairmanship of the powerful House Energy and Commerce Committee. Agassi slips out of the conference and an hour later I catch up with him across the Bay at San Francisco City Hall where he and representatives of Governor Arnold Schwarzenegger and the mayors of San Francisco, San Jose and Oakland announce a $1 billion project to build a regional network of electric car charging stations. Better Place has signed similar deals with governments in Israel, Denmark and Australia, but California is the company's first foray into the U.S. market. Planning for the Bay Area network begins in 2009 with construction scheduled to start in 2010 and commercial rollout set for 2012.

The designers, engineers, and others tackling the environmental problems we face never cease to come up with amazingly imaginative ideas. Here are some of our favorite recent projects:

Australian mining firms, hit by high fuel costs and falling commodity prices, could soon swap their diesel generators for 24-hour, solar-power systems, the head of a private renewable power firm said on Thursday. Mining firms are also worried about an emissions trading scheme set to begin in Australia in 2010, Steve Hollis, CEO of Sydney-based Lloyd Energy Storage, told Reuters in an interview.

f a project isn't sold to the community it will struggle to gain public acceptance There are suddenly plans for a lot of wind-based power generation blowing into Washington's Pacific County, possibly a hint at what may occur in many of the coastal counties of Oregon and Washington in the years ahead. A "joint operating agency" of Washington state electricity providers is planning an 82-megawatt wind turbine farm in the Naselle area, with completion of up to 45 wind turbines eyed in 2011. A smaller, very interesting four-turbine project is getting started in northern Pacific County and southern Grays Harbor County. In total, all this may be enough to power some 40,000 average-sized homes.

A home wind turbine already installed at 250 sites in Scotland is now being sold across the pond. Cascade Engineering said Monday the Swift wind turbine, for homes and other buildings, is available in the U.S. and Canada. (Credit: Cascade Engineering) The Swift tries to set itself apart from existing small wind turbines with a design that reduces noise. Also, the turbine can be attached to a home, rather than to a free-standing pole or tower. Like other wind turbines, the Swift has blades that turn and power a generator. But rather than the typical three blades, the Swift has five and a ring that goes around them. That "outer diffuser" ring cuts the noise level to 35 decibels and reduces vibration, according to the company.

Here's a wave power technology which you may not have heard of: It's called the Searaser and (though only in prototype stages, I've got some reservations about how well it may scale up, as well as the name which somehow I always see as 'Sea Eraser') it may be worth watching. The principle is fairly simple and proven in a different context: Use the Searaser to pump quantities of sea water up a hill where it can be stored in ponds until needed and then released downhill to drive hydroelectric turbines to create power. This is how the Searaser works:

Here's one for the alternative wind power experiments file - a report from BusinessWeek on an interesting design idea, inspired by the Tacoma Narrows Bridge collapse of 1940 - Humdinger's Wind Power Alternative. As an MIT engineering undergraduate visiting the rural fishing village of Petite Anse, Haiti, in 2004, Shawn Frayne hoped to devise a way to convert abundant agricultural waste into cheap fuel. But the budding engineer soon found that the community's mainly poor residents faced an altogether more immediate need. Unconnected to the local power grid, they relied heavily on dirty kerosene lamps, which are not only costly to operate but also unhealthy and dangerous. He decided to devise an alternative-a small, safe, and renewable power generator that could be used to power LED lights and small household electronics, such as radios.

Lonnie Johnson has some impressive hard science credentials. He's worked for the Strategic Air Command and for NASA's Jet Propulsion Laboratory, outfitting missions to Mars, Jupiter and Saturn. He holds about 100 patents, many of them in that arcane spot where chemistry, electricity and physics cross into the marketplace. And his latest invention appears to do the impossible: generating electricity with no fuel and no moving parts. But he's still known as Mr. Squirt Gun. Even among the geniuses who gathered to honor him and his new thermo-electrochemical converter at a "Breakthrough Awards" banquet in Manhattan this month, the Atlanta scientist's new invention was ignored when his most famous device was revealed.

Researchers at Ohio State University have accidentally discovered a new solar cell material capable of absorbing all of the sun's visible light energy. The material is comprised of a hybrid of plastics, molybdenum and titanium. The team discovered it not only fluoresces (as most solar cells do), but also phosphoresces. Electrons in a phosphorescent state remain at a place where they can be "siphoned off" as electricity over 7 million times longer than those generated in a fluorescent state. This combination of materials also utilizes the entire visible spectrum of light energy, translating into a theoretical potential of almost 100% efficiency. Commercial products are still years away, but this foundational work may well pave the way for a truly renewable form of clean, global energy.

The Interior Department announced yesterday that is making 190 million acres of federal land available for lease by private interests for development of geothermal energy projects. The Federal and state governments will share in the proceeds of any projects developed on the leased lands. Interior Secretary Dirk Kempthorne said it is estimated that the available leases could produce enough energy to generate 5,540 megawatts of electricity, enough to power 5.5 million homes.
