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.
Key differences in solar wind models
15 May 2017 at 9:59am
The challenge of predicting space weather, which can cause issues with telecommunications and other satellite operations on Earth, requires a detailed understanding of the solar wind (a stream of charged particles released from the sun) and sophisticated computer simulations. New research has found that when choosing the right model to describe the solar wind, using the one that takes longer to calculate does not make it the most accurate.
Scientists track porpoises to assess impact of offshore wind farms
5 May 2017 at 12:16pm
A new study is the first in a series to understand how marine mammals like porpoises, whales, and dolphins may be impacted by the construction of wind farms off the coast of Maryland. The new research offers insight into previously unknown habits of harbor porpoises in the Maryland Wind Energy Area, a 125-square-mile area off the coast of Ocean City that may be the nation's first commercial-scale offshore wind farm.
High-flying experiments demonstrate potential of balloon-borne infrasound det...
13 Apr 2017 at 9:00am
Experiments conducted high in the skies over New Mexico suggest that balloon-borne sensors could be useful in detecting the infrasound signals generated by small, extraterrestrial debris entering Earth's atmosphere.
Americans used more clean energy in 2016
10 Apr 2017 at 12:48pm
Americans used more renewable energy in 2016 compared to the previous year, according to the most recent energy flow charts. Overall, energy consumption was nearly flat.
New radar scanner tests wind turbine blades for defects
10 Apr 2017 at 5:53am
Thanks to the innovative radar scanner, defects in the material composition of the wind turbine blades can now be detected with far greater accuracy and visualized in a cross-sectional view, thereby saving costs in production and operation.
Unique wave tank helps scientists understand threat of rogue ocean waves
7 Apr 2017 at 8:30am
A team of scientists has demonstrated how ocean winds can generate spontaneous rogue waves, the first step to predicting the potentially dangerous phenomena.
Record new renewable power capacity added worldwide at lower cost
6 Apr 2017 at 9:16am
As clean technology costs continue to fall, the world added record levels of renewable energy capacity in 2016, at an investment level 23 percent lower than 2015, new UN-backed research shows.
Predicting the limits of friction: Scientists look at properties of material
5 Apr 2017 at 7:19am
Materials scientists have developed a model to predict the limits of friction behavior of metals based on materials properties -- how hard you can push on materials or how much current you can put through them before they stop working properly.
