On soft ground? Tread lightly to stay fast

Fri, 10/09/2015 - 2:25am
Soft steps and large feet can allow animals and robots to maintain high speeds on very loose soil and sand. These findings offer a new insight into how animals respond to different terrain, and how robots can learn from them.

America has fallen behind on offshore wind power

Tue, 09/29/2015 - 10:30am
The United States has fallen behind on offshore wind power, experts say. Their findings show that while offshore wind turbines have been successfully deployed in Europe since 1991, the U.S. is further from commercial-scale offshore wind deployment today than it was in 2005.

Offshore wind farms could be more risky for gannets than previously thought, study shows

Mon, 09/28/2015 - 7:21am
Offshore wind farms, which are to be built in waters around the UK, could pose a greater threat to protected populations of gannets than previously thought, according to a new study.

Greening the electric grid with gas turbines

Mon, 09/21/2015 - 10:25am
Much of the nation's energy policy is premised on the assumption that clean renewable sources like wind and solar will require huge quantities of storage before they can make a significant dent in the greenhouse gas emissions from electricity generation. A new study pokes holes in that conventional wisdom. The analysis finds that the supply of wind and solar power could be increased tenfold without additional storage.

Boost in available wind power for the Midwest with global warming

Fri, 09/18/2015 - 9:54am
Mother Nature will be delivering a future gift of 2 percent more wind energy in the Midwest, U.S. if regional climate models are correct, according to new research.

How to curb emissions: Put a price on carbon

Thu, 09/03/2015 - 11:17am
Literally putting a price on carbon pollution and other greenhouse gasses is the best approach for nurturing the rapid growth of renewable energy and reducing emissions. While prospects for a comprehensive carbon price are dim, especially in the US, many other policy approaches can spur the renewables revolution, according to a new policy article.

As wind-turbine farms expand, research shows they could offer diminishing returns

Mon, 08/31/2015 - 11:37am
A slowdown effect triggered by wind turbines is substantial for large wind farms and results in proportionally less renewable energy generated for each turbine versus the energy that would be generated from an isolated wind turbine, scientists report.

Technique designed to predict how much energy waves will be bringing

Mon, 08/31/2015 - 9:18am
Marine energy has a great future potential according to the experts, but there is still a long way to go before it can be used on a large scale. A team of researchers has now developed a technique to forecast wave energy several hours in advance.

Way for eagles and wind turbines to coexist

Thu, 08/27/2015 - 2:44pm
Collisions with wind turbines kill about 100 golden eagles a year in some locations, but a new study that maps both potential wind-power sites and nesting patterns of the birds reveals sweet spots, where potential for wind power is greatest with a lower threat to nesting eagles.

New technology could reduce wind energy costs

Thu, 08/13/2015 - 12:02pm
When a bearing inside a wind turbine is subject to a load, its thickness is reduced by a very small amount due to elastic deformation, and the speed of sound is affected by the stress level in the material. Both these effects change the time of flight of an ultrasound wave through a bearing. A novel technique has been developed to predict when bearings inside wind turbines will fail which could make wind energy cheaper.

Price of wind energy in the United States is at an all-time low, averaging under 2. 5¢/kwh

Mon, 08/10/2015 - 11:38am
Wind energy pricing is at an all-time low, according to a new report. The prices offered by wind projects to utility purchasers averaged under 2.5¢/kWh for projects negotiating contracts in 2014, spurring demand for wind energy.

Lobster-eye imager detects soft X-ray emissions

Tue, 07/28/2015 - 10:07am
A group of scientists have described developing and launching their imager, which centers on "Lobster-Eye optics," as well as its capabilities and future applications in space exploration.

Wind energy provides 8% of Europe's electricity

Fri, 07/24/2015 - 7:19am
EU’s grid connected cumulative capacity in 2014 reached 129 GW, meeting 8% of European electricity demand, equivalent to the combined annual consumption of Belgium, the Netherlands, Greece and Ireland. According to a report, the impressive growth of the industry will allow at least 12% electricity share by 2020, a significant contribution to the goal of the European energy and climate package of 20% share of energy from renewable sources.

Siting wind farms more quickly, cheaply

Fri, 07/17/2015 - 12:10pm
A new statistical technique that yields better wind-speed predictions than existing techniques do -- even when it uses only three months' worth of data -- has been revealed by researchers. That could save power companies time and money, particularly in the evaluation of sites for offshore wind farms, where maintaining measurement stations is particularly costly.

Can you actually hear 'inaudible' sound?

Fri, 07/10/2015 - 11:35am
Are wind farms harmful to humans? This controversial topic makes emotions run high. To give the debate more objectivity, an international team of experts dealt with the fundamentals of hearing in the lower limit range of the audible frequency range (i.e., infrasound), but also in the upper limit range (i.e., ultrasound).

Viaducts with wind turbines, the new renewable energy source

Thu, 07/02/2015 - 8:51am
Wind turbines could be installed under some of the biggest bridges on the road network to produce electricity. So it is confirmed by calculations carried out by a European researchers team, that have taken a viaduct in the Canary Islands as a reference. This concept could be applied in heavily built-up territories or natural areas with new constructions limitations.

Aerodynamic effects can save tens of seconds in cycling time trials

Mon, 06/29/2015 - 12:24pm
Will the Tour de France prologue in Utrecht get the winner it deserves? New aerodynamic research shows that riders in a time trial can save vital seconds by riding closer to the following team car. Over a short distance like the prologue of the Tour de France, that can save as much as 6 seconds: enough to make the difference between winning and losing.

Russia's renewable energy policy: Profitable for investors

Tue, 06/23/2015 - 6:29am
In 2013, Russia implemented an incentive system for renewable energy sources that is based on the wholesale electricity capacity mechanism. It is intended to increase the share of renewable energy in the country's energy production. New researchers demonstrates that the incentive system can make renewable energy investments in wind, solar and small-scale hydro power profitable for investors. However, in order to be profitable the investments must be within the scope of the full Russian support scheme.

Silent flights: How owls could help make wind turbines and planes quieter

Sun, 06/21/2015 - 6:39pm
A newly designed material, which mimics the wing structure of owls, could help make wind turbines, computer fans and even planes much quieter. Early wind tunnel tests of the coating have shown a substantial reduction in noise without any noticeable effect on aerodynamics.
