That is a valid point, I think. That isn't "but what about the environment" but only when convenient. That is local pricing issue which has a very direct and very trackable impact.

If a datacenter opens next door to you, the utility consumption goes up meaning your bill goes up. Unless the datacenter operators are somehow offsetting that increase financially (and that the money is actually be allocated by the city for that purpose), then there is the real impact of datacenters.
