Researcher pushes limit of when water will freeze
6 Dec 2021 at 7:00pm
An engineer is changing what we know about when water freezes as he pushes the limit and gets the best look yet at tiny drops of water as they freeze.
Macrogrid study: Big value in connecting America?s eastern and western power ...
18 Nov 2021 at 5:37pm
A 'macrogrid' that increases the electricity moving between America's Eastern and Western interconnections, two of the biggest power grids on the planet, would more than pay for itself, according to new research.
Wind and solar could power the world?s major countries most of the time
5 Nov 2021 at 10:46am
With the eyes of the world on the United Nations COP26 climate summit in Glasgow, Scotland, strategies for decarbonizing energy infrastructure are a trending topic. Yet critics of renewables question the dependability of systems that rely on intermittent resources.
Tidal stream power can aid drive for net-zero and generate 11% of UK?s electr...
2 Nov 2021 at 6:01pm
A day before world leaders meet at COP26 to discuss the importance of clean energy, scientists from across the UK say that harnessing the power of the ocean's tidal streams can provide a predictable and reliable means of helping to meet the country's future energy demand.
Energy efficiency instead of long-term storage
2 Nov 2021 at 10:17am
Incorporating energy efficiency measures can reduce the amount of storage needed to power the nation's buildings entirely with renewable energy, according to a recent analysis.
Using overpasses as shelter from tornado?
26 Oct 2021 at 9:43am
Meteorologists and emergency workers continue to contest the popular thinking that waiting out a tornado under an overpass is safe. According to the National Weather Service, doing so could actually increase the risk of death, in part because the wind from a tornado is thought to accelerate as it flows under the overpass, in what's known as the wind tunnel effect.
Expansion of wind and solar power too slow to stop climate change
14 Oct 2021 at 11:19am
The production of renewable energy is increasing every year. But after analyzing the growth rates of wind and solar power in 60 countries, researchers conclude that virtually no country is moving sufficiently fast to avoid global warming of 1.5°C or even 2°C. The article "National growth dynamics of wind and solar power compared to the growth required for global climate targets" was published in the journal Nature Energy, written by Aleh Cherp, Vadim Vinichenko, Jale Tosun, Joel A.Gordon and Jessica Jewell.
Climate change threatens hydropower energy security in the Amazon basin
14 Oct 2021 at 10:11am
Hydropower is the dominant source of energy in the Amazon region, the world's largest river basin and a hotspot for future hydropower development. However, a new study warns that in the coming decades, climate change-driven reductions in precipitation and river discharge will diminish the Amazon's hydropower capacity.
Winds of change: Improvements for wind energy production
12 Oct 2021 at 8:23am
In recent years, much progress has been made in the wind energy industry as the cost of development has declined significantly with emerging technologies and incentive policies. Nevertheless, wind farms can be made more efficient. Researchers now examine diurnal and seasonal patterns of wind speeds and their impact on the adequacy of energy production. The results helped them develop a seasonal adequacy assessment procedure.
Wind energy can deliver vital slash to global warming
22 Sep 2021 at 11:33am
Implementing advance wind energy scenarios could achieve a reduction in global warming atmospheric average temperatures of 0.3 to 0.8 degrees Celsius by the end of the century, according to new research.
Making musical performances safer in the era of COVID-19
15 Sep 2021 at 10:51am
Researchers have studied aerosol production from playing wind instruments, singing and acting, allowing them to develop recommendations to minimize COVID transmission.
How do wind turbines respond to winds, ground motion during earthquakes?
24 Aug 2021 at 9:10am
Wind power has experienced fast growth within China during the past decade, but many wind farms are being built within regions of high seismic activity. Researchers are now exploring the dynamic behaviors of wind turbines subjected to combined wind-earthquake loading. The group discovered that changes in the wind increase and decrease the response amplitude of the wind turbine under weak and strong earthquakes, respectively.
Effect of ?eddy killing? in oceans is no longer a matter of guesswork
19 Aug 2021 at 4:50pm
Applying a new coarse-graining, spatial method of analysis to satellite imagery, scientists provide a direct measure of the impact of wind driven eddy-killing on the kinetic energy of ocean currents -- a continual loss of 50 gigawatts, equivalent to the detonation of a Hiroshima nuclear bomb every 20 minutes, year round.
Polymer scientist helps develop new technique for large-scale energy storage
19 Aug 2021 at 9:52am
Electric vehicles require power to be available anywhere and anytime without delay to recharge, but solar and wind are intermittent energy sources that are not available on demand. And the electricity they do generate needs to be stored for later use and not go to waste. New research reveals a more stable way to store this important energy.
Wind turbine night noise
18 Aug 2021 at 10:05am
With wind generation one of the fastest-growing renewable energy sectors in the world, experts are using machine learning and other signal processing techniques to characterize annoying noise features from wind farms. Two new publications from the ongoing Wind Farm Noise Study take another step towards improving wind turbine noise assessment methods, guidelines and wind turbine design to make wind energy more acceptable to surrounding communities.
