I am agreeing with you that the solutions exist, but the will to implement them is going to be the hard part. A big dampener is simply going to be the profit motive. There is more money in siding with the data center than a the households. Are households okay with an increasing in price? Data center is likely to manage that better, or even just pay a bribe to someone. I used food as another example of a problem that is solved. We can grow food without fail and build the rail to get it to where it needs. We just don't because need does not match profit expectation. There are talks of building nuclear power for some data centers, but such talk would not happen for normal households.
