Published Expansion of wind and solar power too slow to stop climate change
(via sciencedaily.com) 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.
Published Climate change threatens hydropower energy security in the Amazon basin
(via sciencedaily.com) 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.
Published Winds of change: Improvements for wind energy production
(via sciencedaily.com) 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.
Published Wind energy can deliver vital slash to global warming
(via sciencedaily.com) 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.
Published Making musical performances safer in the era of COVID-19
(via sciencedaily.com) Researchers have studied aerosol production from playing wind instruments, singing and acting, allowing them to develop recommendations to minimize COVID transmission.
Published How do wind turbines respond to winds, ground motion during earthquakes?
(via sciencedaily.com) 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.
Published Effect of ‘eddy killing’ in oceans is no longer a matter of guesswork
(via sciencedaily.com) 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.
Published Polymer scientist helps develop new technique for large-scale energy storage
(via sciencedaily.com) Original source 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.
