Vertical turbines could be the future for wind farms
27 Apr 2021 at 5:57am
The now-familiar sight of traditional propeller wind turbines could be replaced in the future with wind farms containing more compact and efficient vertical turbines. New research has found that the vertical turbine design is far more efficient than traditional turbines in large scale wind farms, and when set in pairs the vertical turbines increase each other's performance by up to 15%.
Experts' predictions for future wind energy costs drop significantly
15 Apr 2021 at 8:41am
Technology and commercial advancements are expected to continue to drive down the cost of wind energy, according to a new survey. Experts anticipate cost reductions of 17%-35% by 2035 and 37%-49% by 2050, driven by bigger and more efficient turbines, lower capital and operating costs, and other advancements.
Solar and wind power could mitigate conflict in northeast Africa
8 Apr 2021 at 10:14am
A new study shows that several disagreements between Ethiopia, Sudan and Egypt around Africa's largest hydropower plant, the new Grand Ethiopian Renaissance Dam (GERD), could be alleviated by massively expanding solar and wind power across the region.
How improving acoustic monitoring of bats could help protecting biodiversity
25 Mar 2021 at 7:12am
In order to assess the risk of bats dying at wind turbines, it is common practice to record the acoustic activity of bats within the operating range of the rotor blades. In a recent analysis, a team of scientists concludes that the effectiveness of this acoustic monitoring is insufficient to reliably predict mortality risk, especially for bats at large turbines.
Whooping cranes steer clear of wind turbines when selecting stopover sites
11 Mar 2021 at 3:59pm
An article reports that whooping cranes migrating through the U.S. Great Plains avoid 'rest stop' sites that are within 5 km of wind-energy infrastructure.
Field study shows icing can cost wind turbines up to 80% of power production
4 Mar 2021 at 1:10pm
Researchers took their studies of wind-turbine icing out of the lab and into the field to learn how and where ice accumulates on rotating blades. They learned ice on the blades can reduce power production by up to 80%. The field experiments also validated their experimental findings, theories and predictions.
Research contributes to understanding of hypersonic flow
4 Mar 2021 at 7:00am
Using data collected in a NASA wind tunnel, researchers replicated the hypersonic flow conditions of a compression ramp flow using Direct Numerical Simulation.
Low-level jets create winds of change for turbines
23 Feb 2021 at 8:07am
Global wind power capacity has increased more than fivefold over the past decade, leading to larger turbines, but low-level jets are one cause for concern. The effects of these strong, energetic wind flows depend on how high the wind flows are in relation to the turbines. Researchers considered three different scenarios in which the LLJs were above, below, and in the middle of the turbine rotors.
Aging offshore wind turbines could stunt growth of renewable energy sector
16 Feb 2021 at 8:49am
A new study highlights the urgent need for the UK's Government and renewable energy industries to give vital attention to decommissioning offshore wind turbines approaching their end of live expectancy by 2025. The research reveals that the UK must decommission approximately 300 and 1600 early-model offshore wind turbines by 2025 and 2030, respectively.
Common pipistrelle bats attracted to wind turbines
11 Feb 2021 at 6:01am
One of the most abundant bats in Europe may be attracted to wind turbines, a new study shows.
New global 'wind atlas' propels sustainable energy
3 Feb 2021 at 5:53pm
Wind energy scientists have released a new global wind atlas - a digital compendium filled with documented extreme wind speeds for all parts of the world - to help engineers select the turbines in any given region and accelerate the development of sustainable energy.
Taking the chill off icy build-up on planes and wind turbines
17 Dec 2020 at 11:52am
New research is changing the way aircraft and wind turbine operators are addressing the risks related to ice build-up. A team has broadened the scope and functionality of their ice sensors.
Wind tunnel tests will help design future Army tiltrotor aircraft
7 Dec 2020 at 9:41am
After more than three years in development, a team of U.S. Army researchers and industry partners completed the construction of a testbed that will help to inform the design of future Army rotorcraft. The team plans to test the TiltRotor Aeroelastic Stability Testbed, or TRAST in a massive wind tunnel at the NASA Langley Research Center to gauge the effectiveness of modern tiltrotor stability models.
