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.
Scientists design electricity generator that mimics trees
31 Jan 2017 at 9:43am
A prototype biomimetic tree has been built that generates electricity when wind blows through its artificial leaves. The researchers think such technology may help people charge household appliances without the need for large wind turbines.
100% renewable energy sources require overcapacity
25 Jan 2017 at 9:07am
Germany decided to go nuclear-free by 2022. A CO2-emission-free electricity supply system based on intermittent sources, such as wind and solar -- or photovoltaic (PV) -- power could replace nuclear power. However, these sources depend on the weather conditions. Scientists have now analysed weather conditions using 2010, 2012, 2013 and 2015 data derived from the electricity supply system itself, instead of relying on meteorological data.
Computational modeling reveals anatomical distribution of drag on downhill sk...
16 Jan 2017 at 6:14am
Minimizing air resistance and friction with snow is key to elite performance in downhill skiing. Experiments in wind tunnels have revealed the total drag experienced by skiers, but have not provided precise data on which parts of the body cause the most air resistance when adopting the full-tuck position.
New insights into fluctuations of wind energy, with implications for engineer...
31 Dec 2016 at 3:49pm
The amount of energy generated by renewables fluctuates depending on the natural variability of resources at any given time. The sun isn't always shining, nor is the wind always blowing, so traditional power plants must be kept running, ready to fill the energy gap at a moment's notice. Because the grid has no storage, and unlike coal or nuclear, there is no control over the fluctuating production of renewable energy, the energy they produce has to be consumed straight away, or risk collapsing the electrical grid. On particularly windy days, for example, surges in power generated by wind turbines have been known to overwhelm the electrical grid, causing power outages. To avoid this, operators of large power plants sometimes resort to paying consumers to use electricity on particularly sunny and windy days when there is too much excess power in the system, in order to balance the supply and demand of energy at the grid.
Wind farms play key role in cutting carbon emissions, study finds
12 Dec 2016 at 7:11am
Wind farms have made a significant impact in limiting carbon emissions from other sources of power generation in Great Britain, a study shows.
Wind turbines may have beneficial effects for crops, research suggests
9 Dec 2016 at 8:17am
Turbulence created by wind turbines may help corn and soybeans by influencing variables such as temperature and carbon dioxide concentration, according to research. The project drew on data generated by research towers set up on a 200-turbine wind farm in Iowa.
New 'printone' tool allows users to create 3-D printed wind instruments in an...
6 Dec 2016 at 8:13am
A new interactive design tool called 'Printone' has now been developed, which provides users with the ability to create functional 3-D printed wind instruments in any shape or form using interactive sound simulation feedback. The team designed 16 free-form wind instruments to play different melodies.

Wind energy is a key part of the global energy future, expanding rapidly throughout the world in onshore and offshore settings. But to be sustainable, large scale, multi-megawatt (multi-MW) wind farming?s economic efficiencies need to be maximized and knowing where to place the turbines within the wind farm is a first step.
