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.
Design could save truck fuel with turbulence-cutting electric wind generators
28 Mar 2017 at 5:32am
Researchers are experimenting with reducing drag on trucks with electric wind devices that mimic the way vortex generators increase lift on airplane wings.
The economic case for wind, solar energy in Africa
27 Mar 2017 at 2:28pm
To meet skyrocketing demand for electricity, African countries may have to triple their energy output by 2030. While hydropower and fossil fuel power plants are favored approaches in some quarters, a new assessment has found that wind and solar can be economically and environmentally competitive options and can contribute significantly to the rising demand.
New nanofiber marks important step in next generation battery development
10 Mar 2017 at 9:17am
Materials researchers have created a nanofiber that could help enable the next generation of rechargeable batteries and increase the efficiency of hydrogen production from water electrolysis.
Sustainable, high energy density battery created
3 Mar 2017 at 6:14am
Researchers announce the development of a novel low cost, rechargeable, high energy density battery that makes the widespread use of solar and wind power possible in the future. It is based on manganese dioxide (MnO2), an abundant, safe and non-toxic material.
US grid can handle more offshore wind power, cutting pollution and power costs
21 Feb 2017 at 12:07pm
Injecting large amounts of offshore wind power into the US electrical grid is manageable, will cut electricity costs, and will reduce pollution compared to current fossil fuel sources, according to researchers who have completed a first-of-its-kind simulation with the electric power industry.
Limited evidence that styrene causes cancer
14 Feb 2017 at 7:42am
In 2011, the styrene, a high volume plastics chemical and animal carcinogen, was the focal point in a 'poison scandal' in the Danish media. Now a registry study of more than 72,000 employees from more than 400 companies that have been exposed to styrene during production of glassfibre reinforced plastics, has not found an increased incidence of a wide range of cancer types.
Svalbard's electric power could come from hydrogen
7 Feb 2017 at 7:43am
The energy supply to Longyearbyen, midway between continental Norway and the North Pole, is a hot topic in the climate debate. Longyearbyen is the largest settlement and the administrative centre of Svalbard, a Norwegian archipelago in the Arctic Ocean. Today, Longyearbyen obtains its electric power and district heating from its coal power plant, the only one in Norway.
