Offshore wind farms expected to reduce clam fishery revenue, study finds
23 Jun 2022 at 12:36pm
An important East Coast shellfish industry is projected to suffer revenue losses as offshore wind energy develops along the U.S. Northeast and Mid-Atlantic coasts, according to two recent studies.
Modern wind turbines can more than compensate for decline in global wind reso...

Wind energy contributes significantly to the energy sector's sustainable, low-CO2 transformation. However, the efficiency of wind turbines depends on available wind resources and the technical characteristics of the turbines.
Inspired by palm trees, scientists develop hurricane-resilient wind turbines
15 Jun 2022 at 6:12pm
New results from real-world tests of a downwind turbine could inform and improve the wind energy industry in a world with intensifying hurricanes and a greater demand for renewable energy.
Death of bats at wind turbines interrupts natural food chains
7 Jun 2022 at 9:10am
The numerous casualties of bats at wind turbines (WT) have a negative impact on the populations of affected species and potentially far-reaching consequences for the biodiversity in rural areas. Until now, it could only be assumed that the death of bats had further consequences. Now, a team of scientists show that natural food chains are interrupted, which can have far-reaching negative consequences for agriculture and forestry. The study demonstrates the extent to which the functional importance of bats for habitats has been underestimated so far.
Ancient ocean floors could help in the search for critical minerals

Studying ancient ocean floors could help us discover minerals needed to produce electric cars and solar panels.
Wind turbines operating without curtailment claim many victims among protecte...
1 Jun 2022 at 6:22am
Protected and rare bats regularly die at wind turbines (WT). This is why the operation of new wind turbines is temporarily curtailed during periods of high bat activity. Old wind turbines run without curtailment, however. A scientific team has now produced an exemplary estimate of bat fatality rates at such old turbines by systematically recording bat carcasses in the vicinity of the turbines. During two months, 70 bats died on average per wind turbine. Even if these figures cannot be extrapolated one-to-one to all 20,000 old turbines in Germany, there is a considerable need for action. The operation of old turbines should be adjusted to the current regulations for new turbines, the authors argue.
As the grid adds wind power, researchers have to reengineer recovery from pow...

When electric grids go down, there's no way to restore them -- 'blackstart' them -- with power from wind turbines. A team is now working to develop strategies and controllers that would reenergize power grids dominated by wind power. In Iowa, wind turbines now produce 55% of the state's electricity.
Experts forecast the wind plant of the future to be taller and more economical
24 May 2022 at 1:36pm
Anticipating key features of wind plants a decade or more ahead of their installation can inform today's investment, research, and energy system planning decisions. Researchers elicited opinions from more than 140 of the world's leading experts about their expectations of future wind plant design in 2035.
Improved wind forecasts save consumers millions in energy costs
17 May 2022 at 8:22am
Scientists determined that by increasing the accuracy of weather forecasts over the last decade, consumers netted at least $384 million in energy savings. The researchers based their predictions on NOAA's High Resolution Rapid Refresh model, which provides daily weather forecasts for every part of the U.S. These include wind speed and direction data, which utilities can use to gauge how much energy their turbines will produce.
Rapid adaptation of deep learning teaches drones to survive any weather

Neural-Fly technology could one day build the future of package delivery drones and flying cars.
Study finds offshore wind could drive down energy costs in New England, US
21 Apr 2022 at 12:41pm
While wind power is expected to be a 'saving grace' during extreme winter storms, researchers wanted to look at whether storms could also disrupt power supplies and drive up prices.
You've heard of water droughts. Could 'energy' droughts be next?
12 Apr 2022 at 1:15pm
Drawing on 70 years of historic wind and solar-power data, researchers built an AI model to predict the probability of a network-scale 'drought,' when daily production of renewables fell below a target threshold. Under a threshold set at the 30th percentile, when roughly a third of all days are low-production days, the researchers found that Texas could face a daily energy drought for up to four months straight. Batteries would be unable to compensate for a drought of this length, and if the system relied on solar energy alone, the drought could be expected to last twice as long -- for eight months.
Lack of marshaling ports hindering offshore wind industry
12 Apr 2022 at 11:10am
A new study finds that the nation's existing and planned marshaling ports, the assembly areas critical to building and deploying offshore wind turbines, will be insufficient by 2023 to meet commitments and will fail to meet projected demand through 2050.
Collision hotspots for migrating birds revealed in new study
11 Apr 2022 at 5:23pm
New research highlights the areas in Europe and North Africa where the construction of wind turbines or power lines is likely to increase the risk of death for migrating birds.
Bionic wing flaps improve wind energy efficiency
22 Mar 2022 at 8:13am
Scientists show a bionic approach combining features of a seagull's wing with an engineered flow control accessory, known as a Gurney flap, can greatly improve wind turbine performance. To achieve the best aerodynamic performance, the scientists simulated the use of the combined flow control accessory in a variety of situations, including high and low angle of attack and pre- and post-stall scenarios. They compared their computational simulations to experimental results for an aircraft wing undergoing a dynamic stall.
