At first glance the big datacenters are going in places with cheap hydro (TVA powers NoVA, right? and OR/WA, although they do use more coal than I would have thought).
Transportation remains one of the biggest potential wins, and some weird things like cement production which are huge outliers relative to economic value created.
An even more clear example is that natural gas is about 30% the price in the US Midwest as it is in Europe or the rest of the world market. That's the whole point of the Keystone XL pipeline. Even oil has a 20% spread right now between central USA and coastal USA/world.
