“A single 1.7 MW wind turbine, like the 315 Fowler Ridge units, involves some 365 tons of materials for the turbine assembly and tower, plus nearly 1,100 tons of concrete and rebar for the foundation. Grand total for the entire Fowler wind installation: some 515,000 tons; for Roscoe, 752,000 tons; for Shepherds Flat, 575,000 tons. Offshore installations of the kind proposed for Lake Erie would likely require twice the materials needed for their onshore counterparts.”
The alter ego of climate change in these renewable energy debates is sustainability: the argument that wind and other “renewable” energies are sustainable, whereas oil, gas and coal are not.
This assertion may have had some merit a few years ago, when it could plausibly be claimed that the world was running out of fossil fuels.…
