Redjard already explained this, the situation for Hungary is similar.

If only there was some massive ball of super heated plasma in the sky from which we could draw energy from, that also moved the atmosphere of the planet which would open another avenue of energy capture, which also happened to move vast quantities of heavy things like water uphill which would also be an opportunity for energy, or if the ground beneath us was warm enough to use for energy, or if there were shiny green rocks the ground that could be used for power.

Yup, surely there have been zero alternatives.
