Wind Energy Reaches Greater Heights

November 7, 2014 by Energy @ MIT

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

December 20, 2013 by Peter Lehner

We need to move as quickly as possible to the clean energy future, and scaling up wind power will be a big part of the solution. Wind and other clean, renewable energy will help end our reliance on fossil fuels and combat the severe threat that climate change poses to humans and wildlife alike.[read more]

Efficient Turbine Spacing Boosts Offshore Wind Farm Output 33 Percent

November 7, 2013 by Silvio Marcacci

Efficient Turbine Spacing

Offshore wind farms already face one of the most inhospitable environments for renewable energy – we know salt water, storms, and waves can combine to reduce output, but are inefficient turbine layouts also sapping generation?[read more]

Will Painting Wind Turbine Blades Minimize Bird Collisions?

August 8, 2013 by Joshua Hill

A new research project has been initiated to determine whether changing the color of wind turbine blades will have any effect on the number of bird deaths caused by birds unceremoniously careening into the massive blades.[read more]

Google acquires Makani

It’s been a long time since we covered Makani Power, the company developing kite-like wind turbines. In fact, it has just been bought by Google, for development under its Google[x] division.[read more]

Wind Energy Growing Faster than Coal in China: False Math

May 20, 2013 by Robert Wilson

coal-fired plants

Now, the inexorable growth of coal in China in the last decade is often news even to people who make some kind of living writing about energy, but could it possibly be slowing down? And could wind be growing faster than coal?[read more]

Last Hurrah for the Wind Power Tax Credit?

August 2, 2012 by Geoffrey Styles


Ahead of Thursday's meeting of the Senate Finance Committee, a bipartisan deal has apparently omitted the expiring production tax credit (PTC) for wind power from a package of "tax extenders"--various expiring federal tax provisions, including the annual "patch" for the Alternative Minimum Tax.[read more]

New Study: Bigger Is Better When It Comes To Wind Turbines

June 25, 2012 by Joseph Romm

According to a  Swiss study, “the larger the (wind) turbine is, the greener the electricity becomes.” The study claims that for every doubling of the size of the turbine, “global warming potential per kWh (is) reduced by 14%.”The study was conducted by Marloes Caduff and his associates at the Zurich Institute of Environmental...[read more]

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]
