Wind power is becoming popular, but disposing of huge turbine blades is a problem. Today, scientists report a composite resin for making these behemoths that could be recycled into new blades or many other products, including gummy bears. They will present their results at ACS Fall 2022.

Offshore Wind Farms Could Disturb Marine Mammal Behavior #ASA182
When an offshore wind farm pops up, there is a period of noisy but well-studied and in most cases regulated construction. Once the turbines are operational, they provide a valuable source of renewable energy while emitting a constant lower level of sound.
Low-Level Jets Create Winds of Change for Turbines
Global wind power capacity has increased more than fivefold over the past decade, leading to larger turbines, but low-level jets are one cause for concern. The effects of these strong, energetic wind flows depend on how high the wind flows are in relation to the turbines. In the Journal of Renewable and Sustainable Energy, researchers considered three different scenarios in which the LLJs were above, below, and in the middle of the turbine rotors.
Supporting Structures of Wind Turbines Contribute to Wind Farm Blockage Effect
Much about the aerodynamic effects of larger wind farms remains poorly understood. New work in this week’s Journal of Renewable and Sustainably Energy looks to provide more insight in how the structures necessary for wind farms affect air flow. Using a two-scale coupled momentum balance method, researchers theoretically and computationally reconstructed conditions that large wind farms might face in the future, including the dampening effect that comes with spacing turbines close to one another.
