A newly opened wind farm on the roof of the Oklahoma Medical Research Foundation is claimed by turbine suppliers Venger to be the largest building-integrated wind farm in the US. But might it be the largest in the world?  Read More

New York's Urban Green Energy has installed the world's first fully integrated wind-powere...

What's claimed to be the world's first fully integrated wind-powered electric vehicle charging station has just been unveiled in Barcelona, Spain. The Sanya Skypump marries a 4 kW turbine developed by New York's Urban Green Energy (UGE) and General Electric's (GE) WattStation charging technology to offer users the chance to juice up an EV using clean, renewable energy.  Read More

Dr. Narayan is testing one of his new batteries by using it to power a small fan (Photo: D...

Revamping a concept that was first explored forty years ago, researchers at the University of Southern California (USC) are putting the final touches on a patent-pending design for cheap, rechargeable, high energy density iron-air batteries. Because of their unique features, the batteries look particularly well-suited to the kind of large-scale energy storage that could accelerate the adoption of renewable energy sources.  Read More

A Siemens B75 blade in its mold

Siemens has released pictures of its truly gargantuan B75 wind turbine rotor blades. As you might imagine, the prototype turbines that will use these blades boast some staggering statistics of their own (Airbuses at the ready, please).  Read More

Workers install a solar array in Tokelau, an island nation that will be powered with renew...

Adopting renewable energy sources such as solar and wind power is a great way to reduce emissions and produce energy locally. In places like remote Pacific islands, however, those benefits are potentially a key to independence. For that reason Tokelau, a 10 sq. km. (3.86 sq. mi) island nation that lies around 500 km (311 mi) north of Samoa and which is a territory of New Zealand, is about to ditch diesel as a source of electricity and switch to solar power.  Read More

The photoactive plastic panel is 70 percent transparent to visible light

A UCLA team has developed a new type of solar cell that is nearly 70 percent transparent to the naked eye. The plastic cells, which use infrared instead of visible light, are also more economical than other types of cells because they are made by an inexpensive polymer solution process and nanowire technology, potentially paving the way for cheaper solar windows.  Read More

The turbine is particularly well-suited to the gusting winds of inner cities

A new prototype wind turbine, 30 years in the making, and designed for flat-pack shipping and easy assembly, has been erected at Keele University in the UK.  Read More

Drexel University research combining the best features of batteries and supercapacitors co...

Researchers at Drexel University are developing an electrochemical flow capacitor (EFC) that combines the storage capabilities of batteries with the much longer cycle life and power output of supercapacitors. The team's goal is to improve the stability of the energy grid and ease the integration of renewable energy sources.  Read More

University of Wisconsin researchers discover nannorod catalyst that works as well as plati...

University of Wisconsin-Milwaukee (UWM) have identified an inexpensive nanorod catalyst with efficiencies rivalling that of platinum. Composed of nitrogen-enriched iron-carbon nanorods, the new catalyst holds the promise of cheaper, more efficient microbial fuel cells (MFCs) that generate their own hydrogen from waste water  Read More

A wave energy project off the coast of Victoria, Australia will comprise 45 PowerBuoys (Ph...

Lockheed Martin has teamed up with Ocean Power Technologies (OPT) to develop one of the world’s largest wave energy generation projects. The 19-megawatt project to be located off the southern coast of Australia in Portland, Victoria, will be built around OPT’s PowerBuoy technology that has previously been trialed by the U.S. Navy off the coast of New Jersey for powering remote sea-based radar and communications systems.  Read More
