Researchers have reported to the American Physical Society that as wind energy scales up, researchers better able to study the fluid dynamics challenges. Twenty years ago, wind energy was mostly a niche industry that contributed less than 1% to the total electricity production in the United States. Wind has since emerged as a serious contender […]

Chinese Academy of Sciences researchers have designed a kind of ‘tiny wind turbine’ that can scavenge wind energy from breezes as little as those created by a brisk walk. The method is a low-cost and efficient way of collecting light breezes as a micro-energy source. Most of the wind available on land is too gentle […]

Each year, wind turbines are responsible for the death of uncountable hundreds of thousands of airborne animals such as birds and bats. To find a constructive way out of this ”green-green” dilemma, companies building and running wind turbines might have to work together with environmental experts and conservationists. Yet a lack of trust between them […]

University of Kansas scientists report a slowdown effect triggered by wind turbines is substantial for large wind farms and results in proportionally less renewable energy generated for each turbine versus the energy that would be generated from an isolated wind turbine. Renewable wind energy is experiencing a boom, with more wind turbines popping up across […]

University of Cambridge researchers have devised a new material that mimics the wing structure of owls which could help make wind turbines, computer fans and even planes much quieter. Early wind tunnel tests of the coating have shown a substantial reduction in noise without any noticeable effect on aerodynamics. Because wind turbines are heavily braked […]
