GE uses plastic surgery on wind turbine blades for more power

Sometimes progress can be its own worst enemy, with early adopters being stuck with obsolete equipment that leaves them with the choice of living with out-dated technology or an expensive replacement. The green energy field isn’t immune to this, and as part of a US$2 million renewable energy project, GE has developed a way to make smaller, less efficient wind turbines into bigger more efficient ones with a bit of plastic (or carbon composite) surgery.

WindPax portable, collapsible wind turbines take a turn at off grid power

Keeping mobile electronic devices powered up can be difficult for the modern camper and hiker. Generating power from Mother Nature in the form of wind and sun is the preferred option for many, with a number of portable solar and wind generators emerging to fill this need. The latest is Windpax, a collapsible, portable wind turbine system designed to not take up too much space in a backpack. Read More

New Wave Energy wants to put power plants in the sky

Harvesting power from the wind and the sun is nothing new. We've seen flying wind turbines and solar power plants that aim to provide clean renewable energy. UK-based New Wave Energy has a bolder idea in the works. The company plans to build the first high altitude aerial power plant, using networks of unmanned drones that can harvest energy from multiple sources and transmit it wirelessly to receiving stations on the ground.

Scientists challenge economics of storing renewable energy

True or false: solar and wind power are freely available and clean, and thus should always be stored when they generate more energy than the grid can use? It's easy to assume that renewable energy should never be turned off, but scientists at Stanford have done the math to find the break-even point where storing energy is better than "wasting," or curtailing, that energy, and their findings aren't necessarily as you'd think.

National Grid report challenges wind energy critics

Squirreled away beneath a recent Telegraph report on the subtleties of badger-culling in the UK was this intriguing morsel of wind energy news, which would seem to challenge the idea that intermittent energy sources such as wind play havoc with grid management. For the 23,700 gigawatt-hours of electrical energy generated by wind in the UK between April 2011 and September 2012, only 22 GWh of electrical energy from fossil fuels "was needed to fill the gaps when the wind didn't blow," it reports. Gizmag contacted the UK National Grid to find out the details. Read More

Dodgy wind? Why "innovative" turbines are often anything but

Virtually every week there are articles about new and innovative methods for harvesting wind energy. And every week more megawatts of capacity from three-blade horizontal-axis wind turbines (HAWT) becomes operational, despite all of the contenders. Why aren't these innovative new products knocking the iconic HAWT off its perch? Is it possible to tell which are likely to be viable? These eight points are a useful way to assess which technology has potential, and which are likely just hot air. Read More

Google aims to take wind power to new heights with acquisition of Makani Power

Having already put its Google Wallet where its mouth by backing a solar power tower plant in California to the tune of US$168 million, Google has now turned to wind power. According to a report from Bloomberg Businessweek, the search giant has acquired Makani Power, a California-based startup whose Airborne Wind Turbine (AWT) technology first caught our interest in 2011.
