![]() In favor of high waste volumes including highest waste rates, high new installed capacity and short lifespan, the waste could reach 69.4 million tons. For the best case – caused by low manufacturing in-process waste rate, low new installed capacity and long blade lifespan – it could result in 21.4 million tons. A study on wind turbine blade waste in 2050, conducted at the University of Cambridge Institute for Manufacturing, came to the estimation of 43.4 million tons of resulting blade waste by weight in 2050. The rest of the world shows a total of 69,000 units with Germany (17,000), Canada (11,500) and Japan (11,500) at the front. The worldwide ranking is led by China with 752,000 installed units, followed by USA with 161,000 units and the United Kingdom with nearly 29,000. Apart from the fact, that wind power plants are not abandoned due to rust, but mainly due to local and state laws or other stipulations: Especially turbine blades are corrosion-resistant, contain valuable raw materials and are waiting to be recovered.Īccording to WEA, the World Wind Energy Association, in 2017 almost one million wind power units were installed. However, the reality is slightly different. At a campaign rally in late February 2020 in Colorado Springs, former President Donald Trump declared that “after a period of time, wind turbines get tired, they get old, they get rusty, and a lot of guys say hey, their useful life is gone, let‘s get the hell out of here”.
