Wind power promotes extractive industries

Reuters reports on the increasing demand for copper due to mandates requiring the building of giant wind turbines:

“Copper is used in wind turbine installations and for sub-sea cables that transfer power back to the grid. ... [W]ind turbines use 3.6 tonnes of copper per megawatt.”

A dissertation from England concludes that wind turbines use ~5.64 tonnes/MW capacity onshore and ~9.58 tonnes/MW capacity offshore.
