Are carbon fiber composites used for the blades? I thought they were or at least are desired to be if the cost of CF comes down. CF manufacture is very very CO2e inefficient, the equivalent of 50 kg(CO2) / kg(CF). Once you make that into a composite, perhaps double. For reference just about all main synthetic polymers are 1-4 kg(CO2)/kg. Wind farms have been known to alter local micro-climates too. Rebar is likely not CO2 cheap, I cannot speak for concrete.

Wind turbine blades are fiber glass.
