By picking Joe Biden as a running mate, Barack Obama may have reassured the electorate about his lack of experience and foreign policy bona fides, according to some pundits. But the coal-state senator may have also taken a step toward shoring up his enviro cred. The Delaware senator is as serious as a heart attack about energy policy-a point The Wall Street Journal's Jeffrey Ball made this weekend.

What if it were possible to bury carbon dioxide over a mile below a power plant in the second worst air basin in the United States? In 2011 the greenhouse gas will be pumped below a power plant in the southern San Joaquin Valley of California. Located in Kern County near Bakersfield, the Clean Energy Systems power plant is powered by different kinds of natural gas and oxygen. It produces five megawatts of energy, enough for 5,000 homes, but the carbon sequestration experiment will increase that to 50 megawatts.

Shortly after Hurricanes Katrina and Rita hit the U.S., Rice University civil and mechanical engineering professor Satish Nagarajaiah studied damage done to offshore drilling platforms in the Gulf of Mexico.

Scientists working at Arizona State University's Laboratory for Algae Research & Biotechnology hope that tiny algae will be able to fuel jumbo jets. Now, their research is being spun-off as a $3 million research and commercialization collaboration between Heliae Development and Science Foundation Arizona to develop, produce and sell kerosene-based aviation fuel derived from algae. The researchers say they've already moved their work from the lab bench to a pilot-scale demonstration and production project.

Swedish company Home Energy recently revealed an innovative wind turbine that spins in a spherical formation. Eschewing traditional rotors for a sleek orb structure, this beautiful rethinking of conventional wind turbine design utilizes the Venturi principle, which funnels wind within the turbine's blades. The resulting spherical wind turbine features increased efficiency and lower noise levels - making it ideal for small scale energy needs such as personal home use. Best of all it's called the Energy Ball: the fun name is an added bonus.

Can you imagine being able to produce enough water in the Sahara to grow crops there? Can you imagine harnessing sufficient quantities of solar power to supply electricity to cities in Africa and cities in Europe? Can you imagine producing a sustainable bio-fuel that doesn't impact on world food supplies? Charlie Paton, Michael Pawlyn and Bill Watts can and what's more they can imagine all these happening in the same place at the same time.

If ever there was a car made for the times, this would seem to be it: a sporty subcompact that seats five, offers a navigation system, and gets a whopping 65 miles to the gallon. Oh yes, and the car is made by Ford Motor (F), known widely for lumbering gas hogs.

The challenge set by Ford Global Technologies is to design a Model-T for the 21st Century - an inexpensive, innovative and sustainable car. Deakin University is the only Australian university and one of only five worldwide invited to participate in the Challenge, part of the celebrations for the 100th anniversary of the fabled Model T; the car that changed the 20th Century. Deakin University's 'under wraps' design for the Ford Global Challenge left for Detroit on 29th August carried by Deakin's Tim de Souza (Chief Design Engineer) and Stuart Hanafin (Portfolio Coordinator). Deakin's project is code-named T2 ('TSquared').

It wasn't the variable of available sunshine in their suburban Chicago neighborhood that inhibited Sarah and Kiril Lozanov from going solar. Rather, it was the challenge of cost - and of earning homeowner's association approval for the new construction solar would warrant on their condominium rooftop.

Visitors to Rehoboth Beach, Del., soon may be greeted by more than sand dunes, seagulls and beach umbrellas. If offshore wind advocates have their way, scores of 140-foot blades will be spinning in the ocean breeze nearly a dozen miles away, barely visible to the sunbathers.

A new breed of solar tower may soon be sprouting up in Namibia, providing the nation with a carbon-free source of electricity and food during the day and night. At one and a half kilometers tall and 280 meters wide, these massive solar updraft towers could potentially produce 400MW of energy each - enough to power Windhoek, the nation's capital. Proposed by intellectual property company Hahn & Hahn, the towers generate energy by forcing heated air through a shaft lined with wind turbines. Additionally, the base of each tower will function as a 37 square km greenhouse where crops can be grown.

From Holland, the country famous for its windmills, comes a new design for home wind power. Looking like an eggbeater, it spins quieter and at lower wind speeds than a lot of traditional propeller-type turbines. It's now standard for big wind turbines to have propeller blades. Much of the turning force is generated at the tips, which slice perpendicularly through the air, causing a swooshing noise that some residents nearby have said they find unnerving.

In a high profile campaign, West Virginia citizens have asked for a last minute 'stay of execution' against the imminent destruction of the site of a proposed wind farm on the state's Coal River Mountain. Handing in a petition, signed by more than 8,000 residents, campaigners today called on State Governor Minchin to make good on his commitment to support the development of renewable energy in the state, and order a halt to the destruction of an area with enough wind power potential to supply 150,000 homes.

Integrating solar cells into building materials could make solar power more attractive to homeowners. Seamless solar: The solar system shown here (darker panels) integrates thin-film solar modules directly into a metal roof. Such systems offer cost savings in labor and materials and blend well with buildings' designs. Credit: EnergyPeak In an effort to promote the adoption of solar technology, United Solar Ovonic of Auburn Hills, MI, has teamed with a major roofing company to create a metal roof system that generates electricity from sunlight. The partnership offers seven different prefabricated systems, ranging in capacity from 3 to 120 kilowatts. Tests show that the solar roof panels are rugged and can withstand winds in excess of 160 miles per hour.

A former NASA scientist has used radio waves to transmit solar power a distance of 92 miles (148 km) between two Hawaiian islands, an achievement that he says proves the technology exists to beam solar power from satellites back to Earth. John C. Mankins demonstrated the solar power transmission for the Discovery Channel, which paid for the four month experiment and will broadcast the results Friday at 9 p.m. EDT. His vision is to transmit solar power collected by orbiting satellites as large as 1,102 pounds (500 kg) to lake-sized receiver stations on Earth.

The solar power installation at Applied Materials' headquarters is further evidence that companies looking to go green should think blacktop. The Sunnyvale, Calif.-based maker of gear for making high-tech products announced Friday that it has completed the installation a pair of solar power systems that together can produce 2.1 megawatts of energy--which qualifies it, the company says, as the "largest solar power deployment at a corporate facility in the United States."

Solar energy can be utilized in various ways - to provide electricity, mechanical power, heat and lighting. Passive solar heating and cooling can save substantial electricity bills. Design of a building is very important for tapping passive solar energy. The building and windows are designed in such a way that they carefully balance their energy requirements without additional mechanical equipment. Solar benefits are utilized through windows and pumps, and fans are used minimally. Passive solar energy utilizes building constituents such as walls, floors, roofs, windows, exterior building elements and landscaping to control heat generated by sun. Solar heating designs try to trap and store thermal energy from sunlight directly. Passive cooling minimizes the effects of solar radiation through shading or generating air flows with convection ventilation.

A cheap new way to attach mirrors to silicon yields very efficient solar cells that don't cost much to manufacture. The technique could lead to solar panels that produce electricity for the average price of electricity in the United States.

ON a strip of Santa Monica Boulevard in Los Angeles, a futuristic experiment posing as an ordinary fuel station may be bringing the world one step closer to the hydrogen age. From the moment engineers started dreaming about hydrogen as an alternative to oil, they faced a nagging question: What should come first - the fuel-cell car or the hydrogen pump?
