How wind turbines react to turbulence      (via sciencedaily.com) 

The output of wind turbines can rise or fall by 50 per cent in a matter of seconds. Such fluctuations in the megawatt range put a strain on both power grids and the turbines themselves. A new study presents a new stochastic method that could help to mitigate these sudden swings and achieve a more consistent electricity production.

New methodology reveals health, climate impacts of reducing buildings' energy use      (via sciencedaily.com) 

Increasing energy efficiency in buildings can save money -- and it can also decrease the carbon emissions and air pollution that lead to climate change and health harms. But the climate and health benefits of reducing buildings' energy consumption are rarely quantified. Now, researchers have developed a new method for calculating the health and climate impacts of these energy savings.

New material offers more durable, sustainable multi-level non-volatile phase change memory      (via sciencedaily.com) 

Researchers scientists have unlocked a new realm of possibilities for non-volatile phase change memory, a type of electronic memory capable of retaining data even without power. Traditionally, researchers have relied on chalcogenides, materials with reversible electrical properties during transitions between crystalline and amorphous states. But an exciting alternative has emerged in the form of layered nickelates, complex oxide materials composed of nickel ions. These nickelates, with their unique layered structure and thermally reversible switching of room-temperature electrical resistivity, offer superior performance and sustainability potential.

Electrifying heavy-duty vehicles could reduce environmental inequalities      (via sciencedaily.com) 

If the region surrounding Chicago -- North America's largest freight hub -- shifted just 30% of its current on-road heavy-duty vehicles to electric versions, it would substantially reduce pollution and save hundreds of lives per year, with the benefits largely concentrated in disadvantaged communities, according to a new study. The study authors highlight that neighborhoods with predominantly Black, Hispanic and Latinx residents would benefit the most -- potentially reducing disproportionate pollution and health burdens in historically marginalized areas.
