Glasgow, Scotland, UK. 25 June 2020.
Picture: Windmill turbine fan blades stacked in a holding depot in Govan in Glasgow. What is special about these fan blades is that they have a serrated trailing edge, which enables the reduction in aerofoil noise as the blade cuts through the air. Fan blades on large turbines normally reach speeds around 120 mph, causing noise. As the UK must meet its target for green energy renewables, technology will play a role in reducing the turbines noise footprint. Credit: Colin D Fisher/CDFIMAGES.COM
