New research suggests that many biofuel blends do not contain the advertised amount of biofuel.

While sampling blended biodiesel fuels purchased from small-scale retailers, researchers at the Woods Hole Oceanographic Institution found that many of the blends do not contain the advertised amount of biofuel.

Researchers at Georgia Tech have developed a strategy to capture, store and eventually recycle carbon from vehicles. Georgia Tech researchers envision a zero emission car, and a transportation system completely free of fossil fuels.

Researchers at the Georgia Institute of Technology have developed a strategy to capture, store and eventually recycle carbon from vehicles to prevent the pollutant from finding its way from a car tailpipe into the atmosphere. Georgia Tech researchers envision a zero emission car, and a transportation system completely free of fossil fuels.

Twenty-four 2.5 megawatt wind turbine generators will produce enough carbon-free electricity to power 24,000 homes.

British Petroleum broke ground Wednesday on its first wind project in Texas. The project, named Silver Star I, is located 80 miles southwest of the Dallas/Fort Worth metropolitan area. The 60 megawatt (MW), $100 million project is owned 85% by BP Alternative Energy and 15% by Clipper Windpower.

Evidently, researchers have found a way for you to become Spiderman - or at least act lile him. Our question is: Do you really want to?

IOP Publishing has announced the online publication of “Towards a Spiderman suit: large invisible cables and self-cleaning releasable superadhesive materials” in Journal of Physics: Condensed Matter. The article states that physicists have found the formula for a Spiderman suit that will allow humans to stick to surfaces using the natural form of adhesion used by spiders and geckos.

"A hard rain’s a-gonna fall," Dylan sang. But when rain and storm surges fall on lands protected by weak levees, this means trouble…big trouble. Hurricanes Katrina and Rita were devastating reminders of this frightening fact. How then can we limit trouble when a levee breaches or, better yet, prevent such a break from ever happening again?

...So the powerful Randy Newman song goes. But when rain and storm surges fall on lands protected by weak levees, this means trouble…big trouble. Hurricanes Katrina and Rita were devastating reminders of this frightening fact. How then can we limit trouble when a levee breaches or, better yet, prevent such a break from ever happening again?

Common fertilizer was used by Timothy McVeigh to build the bomb that killed 167 in Oklahoma. Darrell Taulbee, funded by the University of Kentucky and the Department of Homeland Security, is working to make fertilizers blast proof.

Down in the green, rolling hills and farmlands around Lexington, Kentucky, Darrell Taulbee can be found mixing up a batch of his homegrown fertilizer. But he’s not looking to grow a better Big Boy or distill a smoother bourbon, he tells us. Funded by the University of Kentucky and the Homeland Security’s Science & Technology Directorate (S&T), Taulbee sets his sights on something far more sinister.

Blast results from coated (top) and uncoated ammonium
nitrate fertilizer-packed steel canisters. In fact, most of
the blast seen in top photo is from the C4 plastic explosive
used to initiate the AN explosion--not from the AN itself.

It still uses natural gas, and still creates greenhouse gases, but this new process promises to help make hydrogen more plentiful and cheaper.

A new class of catalysts created at the U.S. Department of Energy's Argonne National Laboratory may help scientists and engineers overcome some of the hurdles that have inhibited the production of hydrogen for use in fuel cells.

Global survey finds green costs overestimated by 300% and a need to foster zero net energy construction.

Key players in real estate and construction misjudge the costs and benefits of "green" buildings, creating a major barrier to more energy efficiency in the building sector, a new study by the World Business Council for Sustainable Development (WBCSD) reports.

A cheap and easily scalable technique to produce hydrogen from visible light is close to being a reality.

The prospect for the wide spread use of hydrogen as a portable energy carrier is dependent on finding a clean, renewable method of production. At Penn State University, a research group headed by professor of electrical engineering Craig Grimes in the Materials Research Institute is "only a couple of problems away" from developing an inexpensive and easily scalable technique for water photoelectrolysis - the splitting of water into hydrogen and oxygen using light energy - that could help power the proposed hydrogen economy.

The Department of Energy’s domestic FreedomCAR and Fuels presidential initiative has now gone global, and researchers at Sandia National Laboratories are playing a key role in that worldwide effort.

The experiment shown in this image helps Sandia scientists understand the
hazards associated with an unintended release of hydrogen. The image show
the flames that emerge after a high-pressure jet of hydrogen is released toward
a wall made of cinder block. The radiated heat flux emanating from the flames,
when analyzed and measured, helps researchers evaluate the effectiveness of a
barrier wall in mitigating the risks of hydrogen releases in a dispensing station
setting.
