If it's only 10% as stated then VERY short term it might matter, but in the long run probably not.
There are enough green / renewable places to mine for people that want it. And enough other places that don't care where you can have mining farms.

And lets face it, no matter what you are never going to stop home mining and small operators. If you force the big players out of an area out it just means more and cheaper equipment for others.
