I think the term "farm" has been used for a long time for renewable energy projects e.g. Wind Farm. Probably comes from harvesting natural energy in a field like setting. I don't see anything nefarious there.
Never heard of woke-wash before but i suppose language keeps (d)evolving. At this point arguing against using indigenous names for things (in the country the languages are from), especially when on the banks of the Saskatchewan, seems illogical and a waste of energy (oh, now I'm wasting energy arguing
). I guess I don't really see the need to still name things after someone or some concept any more. Just name things after geography and function and there would be less moaning and more useful and descriptive names - E.L. Smith WTP Solar Farm - it's a solar farm at the WTP - sorted.
Overall I think the solar farm is a net positive and we will be reaping the benefits for years.
