Tens of thousands of blades being disposed of? How long are these windmills lasting? If their useful life is shorter than expected, it means the power is proportionately more expensive.
about ten years... give or take. there seems to a company in Texas that has worked out a way t break them down, but it is already at full compacity if I am interpreting it right.
When those blades spin they lose their edge surprisingly quickly hitting particulates in the air and eroding not to mention the strain of varied torque and varying temperature.
To work in a sense they have to be the opposite of streamlined with a huge volume of mass transiting across the contact surface.
They use cutting edge materials to take the strain but basically you're making propellers that turn out to be white elephants down the line.
