I'm not convinced wind farms wouldn't be affected as well.

With an ash cloud large and dense enough to restrict that much sunlight, wouldn't we also get a different distribution of warmed land and therefore different wind patterns?

Don't forget the abrasive qualities of volcanic ash. The blade surfaces would be eroded, and the internal bearings supporting the blade, the multiplier gears, and generator inside would quickly become trashed.
