I don't think it's out of thin air, it's the reality of what's actually being used in Ukraine, and as comments in this thread have borne out it seems to have legitimate benefits, and so doesn't qualify as greenwashing.

Also if there's greenwashing, it means some questionable practice is being green washed. Apparently you think the idea of decentralization is the thing in this case... but you agree that decentralizing is a good idea and are more against the merits renewables, which is an anti renewables argument but not a correct diagnosis of something being greenwashed.
