See my other reply, when people count energy costs they fail to take into account the existing sunk cost of producing said resources, and the energy from having to build out new infrastructure to create these “more efficient” datacenters.

It’s like when people replace their fridge with a “more efficient” one and wipe out any energy savings with the cost of the new fridge. The difference in energy use will not pay for the new fridge for many years and by then you’ve already replaced the new fridge with another newer “better” one.
