Researchers developing alternatives to fossil fuels are working with everything from algae to babassu oil to corn, but a California company says it can recycle carbon dioxide into fuel. Carbon Sciences claims it has developed a way of using the CO2 emitted during the combustion of coal, oil and other hydrocarbons to create transportation fuels like gasoline and jet fuel. Should Carbon Sciences - or any of the other firms working on similar projects - accomplish this on a large scale, it could bring a reduction in CO2 emissions as well as an abundant supply of renewable 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. 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.

Opportunities in the renewable energy technology sector are becoming more diverse as regulatory support extends to technologies other than wind farms, Steve Read, investment manager of the Ventus Funds, said. Read said the Ventus Funds, venture capital trusts operated by Climate Change Capital, are spreading their investments more evenly between wind farm projects and other renewable energy technologies such as land-fill gas and waste biomass.

Expatriate Australian solar power company Ausra was one of the companies that featured heavily in my post on concentrating solar thermal power earlier in the year. California Governor Arnold Schwarzenegger has opened Ausra's first plant, a 5 MW plant at Kimberlina in central California (the first to open in 20 years) which will generate enough electricity during peak hours to power 3,500 homes. Ausra's next plant will be a 177 MW plant nearby in San Luis Obispo County. The SMH quoted Schwarzenegger as saying "This next generation solar power plant is further evidence that reliable, renewable and pollution-free technology is here to stay, and it will lead to more California homes and businesses powered by sunshine. Not only will this large-scale solar facility generate power to help us meet our renewable energy goals, it will also generate new jobs as California continues to pioneer clean-tech industry".

Frontline's "Heat" is not just good, but bordering on "scary good", and should instantly vault to the front ranks of journalism devoted to global warming. I watched "Heat" last night, and was extremely impressed with the production's overall approach to the topic as well as how often the primary on-screen journalist, Martin Smith, cut right to the core of an issue with a tough, point-blank question.[1] Even as some parts of the show made me ache as it described just how daunting this challenge is, I wanted to cheer the tough, unblinking stance the show took in treating the topic.

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.

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.

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.

Many people have been asking me if there is a video of the presentation I gave at this year's O'Reilly Web 2.0 Expo available anywhere. I asked the organisers but they said they hadn't recorded it. Then my good friend Andrea Vascellari came to the rescue. I knew he had attended the presentation but I was unaware that he recorded it. He published the video above this afternoon so for all those who were interested, here you go…

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.

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.

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."

"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."�

Solar power has a number of excellent advantages, including great savings and saving the environment. An excellent product out there that helps users get the most out of their solar power is the Appolo SolarT80 MPPT Charge Controller.

Scientists say that a type of rock found at or near the surface in the Mideast nation of Oman and other areas around the world could be harnessed to soak up huge quantities of globe-warming carbon dioxide.
