For some reason I imagine that you are not managing e.g. Chinese mining operations.
Everyone will look for cheapest power, but that on its own does not make it renewable.
Plus, regardless of your source, as long as you haven't built your own plant, the grid has to cover for the loss. If there isn't an abundance of renewable energy on the grid, then the operation wasn't neutral at all.
You're correct, I'm dealing with exclusively American operations or American operations run by foreign entities. Most have relocated to explicitly get onto hydro. YMMV, but that's been my experience.
