Turbine Construction and Efficiency

Wind turbines across the globe are being made taller to capture more energy from the stronger winds that blow at greater heights. But it’s not easy, or sometimes even economically feasible, to build taller towers, with shipping constraints on tower diameters and the expense involved in construction.[read more]

Polish Town Rejects Coal, Seeks Energy Independence

September 6, 2014 by Clare Taylor

Poland and Energy Sources

Poland is one of Europe's fastest-growing economies and heavily dependent on coal, which generates around 90 % of the country's electricity. One rural town, the Commune of Kisielice, decided to forge a path to sustainable energy - and has been recognised across Europe for their pioneering work.[read more]

Field Mobility Crucial for Wind Energy Projects

July 10, 2014 by Dan Liggett

Renewable energy projects and infrastructure can be great distances from the company’s headquarters or satellite offices. Supervisors, technicians and other workers in the field need technology that will allow them to maximize productivity, even though they are far from their desk.[read more]

High-Flying Turbine Produces More Power

May 16, 2014 by Energy @ MIT

Airborne Wind Energy Turbine

For Altaeros Energies, the sky’s the limit when it comes to wind power. Founded by Ben Glass and Adam Rein, Altaeros has developed the first commercial airborne wind turbine, using a helium-filled shell to float as high as a skyscraper and capture the stronger, steadier winds available at that altitude.[read more]

Wind Energy and Wildlife Protection Must Go Together

Bill Stovall is a long-haul trucker from Texas. He used to deliver fresh meats and produce, a job he did with pride. But for the past few years, he's been hauling a very different kind of load, in a special, telescoping truck-trailer combo that stretches out to 168 feet. All that length is devoted to carrying a single object: the 130-...[read more]
