That math is ~, but the impact is worse than the meme shows.
Turbine base, e.g. (piled raft)=
~32 piles @ 18"x18"x33'
+
Cap @ 25' x 4'
= ~70 cu m per turbine
@ 150lbs/cu ft or 4,050lbs/cu yd or 2,400 kg/cu m
That's a "piled raft;" it's at the very low end, concrete-volume-wise. A Pile Group or Raft would be 2x to 5x as much concrete.
Which means, the smallest conceivable concrete turbine base is ~168,000 kg or 370,376 lbs.
CO2 from production of one lb of concrete? .9lbs of CO2 per lb.
I.e., at the LOW end, the turbine base causes the release of ~333,338lbs of CO2 FROM THE CONCRETE ALONE, before you get to mining and transportation of the materials, manufacture and transportation of the component parts, assembly and transportation of the assembled parts, site preparation and machinery required for installation, feeding, housing, transportation, and clothing of the installation workers, resource extraction, refinement and transportation, manufacture, assembly, and transportation and installation of the transmission lines necessary to convey electricity generated at the turbines, etc, etc, etc.
