    For comparison, a blast furnace making steel uses on the order of 3600 GWh/yr and the energy comes primarily from coal.

    9Gwh is a high number for a datacenter, but industrial processes use much more and much dirtier energy.

    That’s also one datacenter and the largest. Whereas there are many, many blast furnaces running all over the world.
