1. Local governments can require that if the data center peak load is 1.0GW, they must provision transmission and generation capacity for the local region of 1.2GW; the extra power can be given to the neighbors at substantial discount.
2. Construct a public swimming complex nearby, heated with waste data center heat.
3. Local governments can enforce strict limits on environmental noise at the property boundary. I've personally stood right next to a 150MW-class datacenter and experienced sound levels less than traffic from a typical suburban 4-lane street; making the datacenter quieter than any other industrial use is a choice the builder can make if they have the right incentives.
Setup directional microphones around the perimeter, and fine them $25,000 per minute per dB above the agreed threshold. Distribute the fines to the neighbors. Failure to pay promptly means the sheriff shuts down the power.
All of these options are far cheaper than launching the data center into space...
