Here in the Pacific Northwest the winds are strongest in the spring, just when the hydro dams have excess water for the turbines. Wind power is a poor match to the needs of the region.

Despite the title this is mostly about the difficulties of recycling used wind turbine blades. The big offshore turbines appear not to be lasting the stated design life.
