Sweden may hypothetically purchase miners 2x more efficient than the average miner and therefore need only half their countries power output.
In addition I would be surprised if Sweden can't source power from other countries ( prove me wrong I'm not sure on this one)
They absolutely can, though I think they've been mostly net exporters for the last ~10 years.
According to https://www.svk.se/siteassets/drift-av-stamnatet/bilder/map-..., Sweden has 7 HVDC (Denmark x2, Germany x1, Poland x1, Lithuania x1, Finland x2) plus 2x 400kV to Denmark, 2x to Finland and 4x to Norway (plus a 220kV).
