I read something recently that stated, if you take all the energy that is required to build a wind turbine and set it up. The cost includes the mining of ores, the manufacturing process, the transportation, setup and the maintenance costs. It can spin until it disintegrates and will never be net positive energy.
I don't know if it's true, it could be full of shit, wish I could find it again.

"In the scientific literature EROIs for recent wind turbines normally vary between 20 and 50.[11][better source needed]. Data collected in 2018 found that the EROI of operational wind turbines averaged 19.8 with high variability depending on wind conditions and wind turbine size.[12] EROIs tend to be higher for recent wind turbines compared to older technology wind turbines. Vestas reports an EROI of 31 for its V150 model wind turbine.[13]"
