Renewable energies: No wind turbine disturbing the scenery
20 Jul 2021 at 8:44am
In the Alpine foothills, in low mountain ranges, or on the seacoast, expansion of wind energy use often meets popular resistance. Researchers have now studied what this means for the energy transition.
Data identifies turbine wake clustering, improves wind farm productivity via ...
20 Jul 2021 at 8:44am
Researchers describe a real-time method for potentially helping turbine farms realize additional power from the clustering of their turbines. Their method requires no new sensors to identify which turbines at any given time could increase power production if yaw control is applied, and validation studies showed an increase of 1%-3% in overall power gain.
Renewable energy OK, but not too close to home
19 Jul 2021 at 9:03am
When it comes to transitioning from carbon-based to renewable source energy systems, Americans are on board. They're less keen, however, having these new energy infrastructures built close to their homes.
Remotely-piloted sailboats monitor 'cold pools' in tropical environments
8 Jul 2021 at 2:03pm
Researchers used remotely-piloted sailboats to gather data on cold air pools, or pockets of cooler air that form when rain evaporates below tropical storm clouds. These hard-to-study phenomena are thought to have broader effects on tropical weather.
Better method to predict offshore wind power
30 Jun 2021 at 8:54am
Researchers have developed a machine learning model using a physics-based simulator and real-world meteorological data to better predict offshore wind power.
How to build a better wind farm
28 Jun 2021 at 2:05pm
Location, location, location -- when it comes to the placement of wind turbines, the old real estate adage applies, according to new research.
A novel energy storage solution featuring pipes and anchors
23 Jun 2021 at 10:06am
What do pipes and anchors have to do with storing energy? More than you might think! A new study explored the potential of a lesser known, but promising sustainable energy storage system called Buoyancy Energy Storage.
Are wind farms slowing each other down?
3 Jun 2021 at 2:12pm
Many countries promote the expansion of wind farms. However, if these offshore wind farms are set up close to each other, wind energy and hence electricity yield is reduced. A study shows that the losses with increasing offshore wind energy production will be considerable and detectable as large scale pattern of reduced wind speed around wind farms.
Technique to evaluate wind turbines may boost wind power production
25 May 2021 at 8:36am
With a global impetus toward utilizing more renewable energy sources, wind presents a promising, increasingly tapped resource. Despite the many technological advancements made in upgrading wind-powered systems, a systematic and reliable way to assess competing technologies has been a challenge. Researchers have used advanced data science methods and ideas from the social sciences to compare the performance of different wind turbine designs.
New framework incorporating renewables and flexible carbon capture
18 May 2021 at 5:54pm
As the global energy demand continues to grow along with atmospheric levels of carbon dioxide (CO2), there has been a major push to adopt more sustainable and more carbon-neutral energy sources. Solar/wind power and CO2 capture - the process of capturing waste CO2 so it is not introduced into the atmosphere - are two promising pathways for decarbonization, but both have significant drawbacks.
Wake steering potentially boosts energy production at US wind plants
18 May 2021 at 8:47am
Wake steering is a strategy employed at wind power plants involving misaligning upstream turbines with the wind direction to deflect wakes away from downstream turbines, which consequently increases the net production of wind power at a plant. Researchers illustrate how wake steering can increase energy production for a large sampling of commercial land-based U.S. wind power plants. Several were ideal candidates.
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.
