Fundamentals of water repellency revealed
14 Aug 2017 at 6:27am
The frictional mechanism that resists the motion of drops on inclined surfaces and when affected by wind drag has now been revealed by a team of researchers. They have also developed a theory by which sliding of drops off surfaces of different materials can be predicted. This makes it possible to systematically develop hydrophobic surfaces by modifying their base material and roughness.
Night vision for bird- and bat-friendly offshore wind power
11 Aug 2017 at 7:20am
ThermalTracker software analyzes video with night vision, the same technology that helps soldiers see in the dark, to help birds and bats near offshore wind turbines.
Jackdaws flap their wings to save energy
11 Aug 2017 at 6:36am
For the first time, researchers have observed that birds that fly actively and flap their wings save energy. Biologists have now shown that jackdaws minimize their energy consumption when they lift off and fly, because the feathers on their wing tips create several small vortices instead of a single large one. The discovery could potentially be applied within the aeronautical industry.
Prairie-chicken nests appear unaffected by wind energy facility
9 Aug 2017 at 4:33am
Wind energy development in the Great Plains is increasing, spurring concern about its potential effects on grassland birds, the most rapidly declining avian group in North America. However, a new study suggests that for one grassland bird species of concern -- the greater prairie-chicken -- wind energy infrastructure has little to no effect on nesting. Instead, roads and livestock grazing remain the most significant threats to its successful reproduction.
Annual wind report confirms tech advancements, improved performance, low wind...
8 Aug 2017 at 11:55am
Wind energy pricing for land-based, utility-scale projects remains attractive to utility and commercial purchasers, according to an annual report released by the US Department of Energy. Prices offered by newly built wind projects in the United States are averaging around 2¢/kWh, driven lower by technology advancements and cost reductions.
Distributed wind power keeps spinning, growing
8 Aug 2017 at 11:55am
America's use of distributed wind -- which is wind power generated near where it will be used -- continues to grow, according to the 2016 Distributed Wind Market Report.
Vertical axis wind turbines can offer cheaper electricity for urban and subur...
3 Aug 2017 at 7:31am
Small vertical axis wind turbines (VAWTs) possess the ability to effectively operate in the presence of high turbulent flow, which makes them ideal energy harvesting devices in urban and suburban environments. In a new article, researchers present results indicating that an optimally designed VAWT system can financially compete with fossil-fuel based power plants in urban and suburban areas, and even spearhead the development of a net-zero energy building or city.
India can integrate 175 GW of renewable energy into its electricity grid
25 Jul 2017 at 9:20am
The US Department of Energy's National Renewable Energy Laboratory has confirmed the technical and economic viability of integrating 175 gigawatts (GW) of renewable energy into India's grid by 2022.
Unbalanced wind farm planning exacerbates fluctuations
17 Jul 2017 at 8:53am
If European countries cooperated better in the field of wind energy, wind power output would fluctuate less. This is the conclusion reached by a group of energy and climate researchers who, for the first time, have combined a long-term analysis of predominant weather patterns with Europe-wide wind electricity generation.
Surveying sea floor animals for offshore renewable energy
7 Jul 2017 at 6:58am
Chunks of sediment from the ocean floor are being used by scientists to analyze animal life and determine environmental impact from offshore energy facilities.
Owls' wings could hold the key to beating wind turbine noise
4 Jul 2017 at 6:36am
Inspiration from owls' wings could allow aircraft and wind turbines to become quieter, suggests a new study. Researchers studied the serrations in the leading edge of owls' wings, gaining new insight into how they work to make the birds' flight silent. Their results point towards potential mechanisms for noise suppression in wind turbines, aircraft, multi-rotor drones and other machines.
Wind turbines: The strength test
9 Jun 2017 at 6:27am
Wind turbines rise into the sky on enormous feet. To ensure these giants can reliably generate electricity for many years to come, the iron processing industry must manufacture their massive components in a stable, resource-saving and yet cost-effective way. However, material inclusions such as dross are often unavoidable while casting. Researchers are currently working to detect and analyze such material defects.
Offshore wind turbines vulnerable to Category 5 hurricane gusts
7 Jun 2017 at 5:53am
Offshore wind turbines built according to current standards may not be able to withstand the powerful gusts of a Category 5 hurricane, creating potential risk for any such turbines built in hurricane-prone areas, new research shows.
Successful field experiments with autonomos drones
2 Jun 2017 at 8:37am
Researchers have performed a successful field experiment with autonomous drones. In two or three years, it will be possible to use this technique for aerial inspection of wind turbines, say the investigators.
Concrete for taller wind turbine towers passes tests, could help expand wind ...
25 May 2017 at 10:12am
An 18-month, $1 million study of concrete technology for taller wind turbine towers has just wrapped up, with results indicating that the taller towers could enable wind energy production in all 50 states.
