In the United States, the wind industry now generates enough electricity to power more than 43 million homes, according to the Department of Energy, with more than 70,000 turbines spinning across 43 states. But while it is one of the cheapest and cleanest energy sources, there is a growing problem. While most of a wind turbine can be reused, its enormous fiberglass blades are difficult to dispose of when they reach the end of a 20-25 year life span. This has led to vast graveyards of these monster pieces of machinery. It’s estimated that 720,000 tons of blade material will be disposed of over the next 20 years in the US, and lawsuits are beginning to spring up over the dumping of blades. Around the world, companies are beginning to figure out ways to resurrect them. EFE/Canvas.
