Вот кстати для всех критиков ветряков, технология для утилизации лопастей теперь уже разработана и пущена в производство:

«Siemens Gamesa Renewable Energy (SGRE) has produced its first six fully recyclable offshore wind turbine blades, the manufacturer has claimed.

It plans to use these blades in offshore wind farms due to be installed next year, the manufacturer told Windpower Monthly.

The new blades use a new type of resin that makes it possible to efficiently separate it from the other components at the end of the blade’s working life – previously a major obstacle to full recyclability – the firm explained.

After decommissioning, the blade will be immersed in a mild acidic solution heated with renewable energy, which will separate the resin from the fibre-glass, plastic, wood and metals.

This will allow the materials to be recycled for new purposes, including in the automotive industry or in consumer goods like flight cases and flatscreen casings.»

Главное это желание, а путь найдётся.
