Norway ran on 100% renewables for like 80 years, but no one cares.
Only reason we’re not at 100% anymore is because politicians don’t find it a priority to be self-sufficient and it’s much better to sell Norwegian renewable electricity to Europe for a profit, then buy back dirty electricity and let the consumers in Norway pay a cable transit tax to the government.
See, now you get to sell the energy twice, and both times at a higher rate.
