US wind plants show relatively low levels of performance decline as they age
13 May 2020 at 8:14am
Wind plants in the United States remain relatively efficient over time, with only a 13% drop in performance over 17 years, researchers report. Their study also suggests that a production tax credit provides an effective incentive to maintain the plants during the 10-year window in which they are eligible to receive it. When this window closes, wind plant performance drops.
Solar and wind energy sites mapped globally for the first time
4 May 2020 at 12:02pm
Researchers have mapped the global locations of major renewable energy sites, providing a valuable resource to help assess their potential environmental impact.
Supercomputing future wind power rise
14 Apr 2020 at 6:57am
First detailed study of scenarios for how wind energy can expand to 20 percent of total US electrical supply by 2030. Results showed expansion of installed capacity makes small impact on efficiency and local climate by deploying next generation, larger wind turbines. Improved calculations of US wind resources can ensure better decision making and a better, more robust energy supply.
Using fiber optics to advance safe and renewable energy
30 Mar 2020 at 6:34am
Fiber optic cables, it turns out, can be incredibly useful scientific sensors. Researchers have studied them for use in carbon sequestration, groundwater mapping, earthquake detection, and monitoring of Arctic permafrost thaw. Now they have been awarded new grants to develop fiber optics for two novel uses: monitoring offshore wind operations and underground natural gas storage.
Designing lightweight glass for efficient cars, wind turbines
26 Mar 2020 at 11:44am
A new machine-learning algorithm for exploring lightweight, very stiff glass compositions can help design next-gen materials for more efficient vehicles and wind turbines. Glasses can reinforce polymers to generate composite materials that provide similar strengths as metals but with less weight.
Water splitting advance holds promise for affordable renewable energy
9 Mar 2020 at 10:00am
A team has developed a less expensive water electrolysis system that works under alkaline conditions but still produces hydrogen at comparable rates to the currently used system that works under acidic conditions and requires precious metals. This advance brings down the cost of water splitting technology, offering a more viable way to store energy from solar and wind power in the form of hydrogen fuel.
Drones can now scan terrain and excavations without human intervention
5 Mar 2020 at 10:20am
Drones can now scan terrain and excavations without human intervention. New research has allowed artificial intelligence to take over the human-controlled drones currently being used for the task. The algorithm also predicts and counteracts the wind forces acting on the drone body.
Quadrupling turbines, US can meet 2030 wind-energy goals
24 Feb 2020 at 3:34pm
The United States could generate 20% of its electricity from wind within 10 years, without requiring any additional land, according to new research.
Could water solve the renewable energy storage challenge?
19 Feb 2020 at 12:28pm
Seasonally pumped hydropower storage could provide an affordable way to store renewable energy over the long-term, filling a much needed gap to support the transition to renewable energy, according to a new study.
An early warning system for damage in composite materials
18 Feb 2020 at 3:22pm
A team has developed a tool to monitor changes in widely used composite materials known as fiber reinforced polymers (FRPs), which can be found in everything from aerospace and infrastructure to wind turbines. The new tool, integrated into these materials, can help measure the damage that occurs as they age.
New bio-inspired wing design for small drones
29 Jan 2020 at 11:33am
Taking a cue from birds and insects, researchers have come up with a new wing design for small drones that helps them fly more efficiently and makes them more robust to atmospheric turbulence.
Consider marine life when implementing offshore renewable power
17 Dec 2019 at 8:42am
With countries adopting green energy practices, renewable energy now accounts for a third of the world's power. As this trend continues, more countries are looking to offshore energy sources to produce this renewable energy. Researchers identify situations where green technology such as wind turbines, wave energy converters, and other marine renewable energy devices (MREDs) have had negative consequences on marine life.
Supporting structures of wind turbines contribute to wind farm blockage effect
12 Dec 2019 at 7:46am
Much about the aerodynamic effects of larger wind farms remains poorly understood. New work looks to provide more insight in how the structures necessary for wind farms affect air flow. Using a two-scale coupled momentum balance method, researchers theoretically and computationally reconstructed conditions that large wind farms might face in the future, including the dampening effect that comes with spacing turbines close to one another.
Insects' drag-based flight mechanism could improve tiny flying robots
10 Dec 2019 at 8:17am
Thrips don't rely on lift in order to fly. Instead, the tiny insects rely on a drag-based flight mechanism, staying afloat in airflow velocities with a large ratio of force to wing size. Researchers have performed the first test of drag force on a thrip's wing under constant airflow in a bench-top wind tunnel and, drawing from microfabrication and nanomechanics, they created an experiment in which a thrip's wing was glued to a self-sensing microcantilever.
Biodiversity and wind energy
27 Nov 2019 at 9:13am
The location and operation of wind energy plants are often in direct conflict with the legal protection of endangered species. The almost unanimous opinion of experts from local and central government authorities, environmental NGOs and expert offices is that the current mechanisms for the protection of bats in wind power projects are insufficient.
