Ah the old "country's worth of electricity" comparison... Keep in mind that Ireland's entire electricity needs could be covered by a one nuclear power plant (3.8 GW with 4 reactors). IOW, you could offload all Irish datacenters by connecting them to a single nuclear power reactor (~900 MW), a small building that has a footprint of under 50 x 50 meters for the reactor, and another of 100 x 50 meters for the generator.
