AI data centers need electricity, which can be from renewable sources and non-renewable sources, and the exact mix can change from day to day as well as long after these data centers are constructed. The electricity grid is decarbonizing at the fastest pace yet. It's simply a tenuous link. On the other hand there are clear non-renewable fossil fuel being used in our daily lives that desperately need to be electrified, think non-electric vehicles and commercial flights. Even without considering more renewable sources of electricity in the future, ask yourself, on a same carbon emission basis, how much can an AI data center accomplish versus a flight from JFK to SFO? How would the utility function even look like?

The way I see it, modern environmentalists like to pick on data centers just because it’s an easy target without entrenched lobbying. The fossil fuel industry is way worse but they have tremendous lobbying.
