Data centers should at the very least build their own renewable energy generation. It would set the right incentives in place and encourage investment in clean energy generation solutions. It would also present a very compelling problem to direct all that new AI compute towards solving.
The challenge is timing. Power is a relatively low share of the cost of a modern data center, but the length of time it takes for approvals and construction for solar means it would substantially slow down the construction vs. using grid+natural gas turbines which are faster to build and get approval for.
I'm 100% on board with charging data centers more for their power usage. They can afford to pay the extra costs. They would much rather pay in dollars vs. in time.
