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.
New clean energy tech extracts twice the power from ocean waves
17 Aug 2021 at 7:27am
New prototype tech can double the power harvested from ocean waves, an advance that could finally make wave energy a viable renewable alternative.
Powering navigational buoys with help of ocean waves
4 Aug 2021 at 6:01pm
Traditionally used energy harvesting technologies, like photovoltaic panels or wind turbines, suffer from several limitations. In the absence of daylight and wind, neither of the two can supply any power. In the case of ocean buoys, a potential solution is omnipresent: wave energy. Abundant, predictable, and consistent, the ocean's waves can be used to power navigation buoys. Researchers have developed sphere-based triboelectric nanogenerators that can be incorporated directly into navigational buoys to provide electricity from ocean waves.
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.
