The University of NSW have produced a PV system that converts over 40 percent of sunlight ...

Solar researchers working at the University of New South Wales claim to have produced a system that converts over 40 percent of incoming sunlight into electricity, thereby taking the title of highest solar efficiency for a photovoltaic system ever reported.  Read More

The Wind Tree turbine is designed to generate power from low-speed winds

Generally speaking, the peculiar appearance of wind turbines coupled with the fact they perform better when up high and out in the open sees them banished to uninhabited countryside, or even out to sea. But a French entrepreneur believes that sculpting them in the form of an artificial tree could lead to wider adoption in urban centers, making use of low winds that circulate around buildings and streets.  Read More

WaveNET - a floating, flexible, modular and massively scalable wave power generation idea ...

Scotland's Albatern is putting a new, modular spin on renewable energy generation. WaveNET is a scalable array of floating "Squid" generator units that harvest wave energy as their buoyant arms rise and fall with the motion of the waves. Each Squid can link up to as many as three others, effectively creating a large, floating grid that's flexible in every direction. The bigger this grid gets, the more efficient it becomes at harvesting energy, and the more different wave movements it can extract energy from. Albatern's 10-year target is to have 1.25 kilometer-long floating energy farms pumping out as much as 100 megawatts by 2024.  Read More

The Jellyfish Barge operates off-grid and produces its own water via an onboard system of ...

Italian design office Studiomobile has teamed up with the University of Florence's Professor Stefano Mancuso, who is the director of the International Laboratory of Plant Neurobiology, to produce a prototype floating greenhouse in a bid to improve food security in areas with little arable land. The Jellyfish Barge operates off-grid and produces its own clean water via an onboard system of solar distillation.  Read More

Polish architecture firm MFRMGR recently unveiled plans to renovate an offshore WWII era watch tower into a water sports hub and research center. The building will also be outfitted with sustainable technology, enabling it to operate using renewable energy sources.  Read More

Scotland's Whitelee wind farm (Photo:

Scotland is pushing ahead with green energy, with First Minister Alex Salmond claiming that renewables could provide 100 percent of Scotland's energy by 2025. And last month, Salmond's push for wind farms appears to have borne fruit – wind power alone generated some 126 percent of the energy needed to power every home in Scotland in what the World Wildlife Foundation (WWF) is calling a "bumper month." Even solar fared well despite the chilly conditions, with domestic solar PV panels chipping in around a third of the domestic energy bill.  Read More

Most everyone not vested in oil and gas agrees that renewable energies such as solar are a more sustainable option, but cost remains an issue. To make solar more competitive by addressing the high cost of solar cell production, researchers out of Norway have developed a method that could bring down the amount of silicon used per unit area by as much as 90 percent. The price of silicon is a major driver in the cost of solar panels.  Read More

Magic Dirt premium potting soil and Bioproduct Innovation of the Year award winner

Magic Dirt may sound like the soil used by Jack to grow his beans, but the Bioproduct Innovation of the Year award winner is just one result of a process that’s addressing the environmental issues caused by effluence from factory farm feedlots. The process starts with anaerobic digesters, specifically a patented two-stage model from Wisconsin-based DVO, which more efficiently converts manure into three valuable byproducts.  Read More

This large buoy has an array of advanced scientific instruments to measure offshore wind e...

Offshore wind power in the United States is nowhere close to meeting the potential this renewable energy form has to offer. There are a myriad of reasons why, including lack of information on energy-harnessing possibilities at specific sites. The US Department of Energy’s Pacific Northwest National Laboratory (PNNL) is looking to change this, by dropping two very advanced data-collecting buoys into coastal waters.  Read More

Electron microscope images of the nanometer-sized rods of titanium dioxide that cover the ...

Researchers at Ohio State University (OSU) have created a dye-sensitized solar cell that stores its own power by "breathing" air to decompose and re-form lithium peroxide. Its creators believe the device, which effectively combines a battery and a solar cell in one, could reduce renewable energy costs by 25 percent.  Read More
