- AI firm DeepGreen has suggested building data centers underwater
- This would help to keep the locations cool and running efficiently
- But the proposed locations could seriously harm endangered whale species
AI data centers need an awful lot of water to keep their machines running at optimal temperatures, and that creates a problem: just how do you get that much water on-site? One potential solution seems almost blindingly obvious: why not build them underwater? Yet as residents across the US are discovering, that idea is proving to be highly controversial.
Take the recently-pitched $100m underwater data center located off the coasts of Maine and Alaska, for example. AI firm DeepGreen Holdings has proposed building data centers off Western Passage, Maine, and Upper Cook Inlet, Alaska, and they would cover some 1,650 acres and comprise 66 compute pods and 300 tidal turbines.
The problem? Both locations are home to endangered whale populations that could be significantly impacted by the developments. In the case of the Maine site, the Gulf of Maine is linked to critical habits for the North Atlantic right whale. As for Upper Cook Inlet, that’s a designated critical habitat for the endangered Cook Inlet beluga whale.

Whales rely heavily on echolocation to aid their feeding, navigation and social activities. Construction of enormous data centers of this scale would produce sizable noise pollution that could adversely affect the whale populations, potentially threatening what are already endangered animals.
According to researchers (via Gadget Review), the heat produced by the data centers, meanwhile, could scare off the cold-water prey that the whales need to survive.
Putting whales at risk
As you might expect, these projects have not gone down well with researchers and the public. For instance, Cooper Freeman of the Alaska Center for Biological Diversity described the move as “just really outrageous.” Freeman added that “We’re deeply concerned about all the harms this project could bring,” adding that the proposal lacks an awareness of “how dangerous this is for the inlet.”
On Reddit, meanwhile, members of the public seem equally upset at the idea. One described it as “Evil. May these people be judged one day and punished for this level of absolutely evil. Disgusting.” Others were even skeptical that underwater data centers are even feasible in the long run, due to the hardware's longevity.
