Coal consumption has peaked there. Solar is growing explosively.

Which begs the question of why AI DCs can’t be powered with their own solar they build out themselves.

  • No fundamental reason not to power them with renewables, either off-grid or with a small capacity grid connection. The argument that they need to run at full load 24x7 sounds more like a business requirement than a technical one. LLMs in particular with their stateless nature seem like an ideal candidate for global distribution.

    • The capital cost of the AI hardware is high and it depreciates quickly, being worthless in 5 years (or less). To make a profit, it needs to be run 24/7.

      It’s sort of like how airlines like to fly their airplanes as much as possible.
