The world's largest solar thermal generation plant, Ivanpah Solar Electric Generating Syst...

After three years of construction, the Ivanpah Solar Electric Generating System (ISEGS) is now operational. The 392 MW plant, funded by NRG, Google, and BrightSource Energy, is expected to generate enough electricity to power 140,000 homes, each year. NRG announced last week that each of the plant's three units is now supplying electricity to California’s grid.  Read More

The Parasol system uses passive radar sensors and mathematical algorithms to determine if ...

With aspirations to claim 80 percent of its power from renewable sources by the 2050, it follows that Germany is taking a proactive approach to its clean energy transformation. Wind farms, while set to play an important part in achieving this goal, often meet impassioned opposition from disgruntled neighbors piqued by their perpetually blinking beacons. In an effort to address this issue, researchers have developed a sensor system for wind turbines which detects nearby aircraft, switching on a beacon warning system only as they approach.  Read More

The humidity-driven flexing of a spore-covered piece of latex rubber (right) drives the mo...

Ozgur Sahin believes that water evaporation is the largest power source in nature. In an effort to demonstrate the potential of this untapped resource, Sahin and his fellow researchers have created prototype electrical generators with rubber sheets that move in response to changes in humidity thanks to a coating of bacterial spores.  Read More

OTIS (or the Optimal Traveling Independent Space) was created by students at Green Mountai...

Students at Vermont's Green Mountain College Renewable Energy and Ecological Design class have produced an off-grid tiny house that's billed as a new take on the American Dream. While that may seem a stretch, an American Dream centered around a sustainable home with a small footprint would certainly be a step in the right direction, environmentally-speaking.  Read More

The batteries, actually mini fuel cells, could be refilled with sugar as needed (Photo: Sh...

Even today's best rechargeable lithium batteries do lose their ability to hold a charge after a while, and are considered toxic waste once discarded. In just a few years, however, they may be replaced by batteries that are refillable and biodegradable, and that will also have a higher energy density yet a lower price ... and they'll run on sugar.  Read More

An inexpensive high capacity organic battery has been developed by Professor Michael Aziz ...

Researchers at Harvard have developed an inexpensive, high capacity, organic battery that uses carbon-based materials as electrolytes rather than metals. The researchers say the technology stands to be a game-changer in renewable energy storage by solving the intermittent generation problems faced by renewable sources, such as wind and solar. The battery offers large volume electricity storage not possible with solid-state batteries and at a fraction of the cost of existing flow battery technology.  Read More

Biocrude produced using the new process

Engineers at the US Department of Energy’s Pacific Northwest National Laboratory (PNNL) have created a continuous process that produces useful crude oil minutes after harvested algae is introduced. This new process does not require drying out the algae, which grows in water, saving time and energy that would be otherwise wasted. The final product can be refined into aviation fuel, diesel, or gasoline.  Read More

Spectrolab has achieved a new world record efficiency for a multi-junction solar cell (Pho...

Spectrolab has set a new solar cell efficiency record of 38.8 percent for a ground-based multi-junction solar cell. The new world record doesn't exactly smash the previous mark of 37.8 percent, which was also set by Spectrolab, but is welcome news in a field where every percentage point counts.  Read More

MIT's high-performance membranelss flow battery could be used to store green energy for th...

Researchers at MIT have come up with a new design for a rechargeable flow battery that does away with the expensive and ineffective membrane of previous designs. The device could prove the ideal solution for effectively storing energy from intermittent power sources such as solar and wind power.  Read More
