An estimated 40 million tons of wind turbine blades will end up in landfills by 2050.
Each modern blade weighs around 10 to 15 tons--mostly fiberglass and epoxy composites with 1 to 2 tons of carbon fiber, balsa and foam, plus roughly a ton of steel and copper for structural support and lightning protection.
All mined, smelted and transported using fossil fuels.
Then once they wear out, after just 15 years, those complex materials are almost impossible to recycle, so most are simply buried.
It's another hidden cost of green energy and the complete opposite of sustainable.
