You're stuck on the same logic loop of "You can't use nuclear because there isn't enough solar", when nobody said we should only use nuclear. OP wanted to know

You're stuck on the same logic loop of "You can't use nuclear because there isn't enough solar", when nobody said we should only use nuclear. OP wanted to know if solar would be sufficient for MN winters, and if not, what else would be required. He wanted a "Convincing analysis". The sun doesn't rise above 30deg over the horizon, for weeks. (MN > 45deg latitude, and earth tilts away by up to 23.5 deg). It gets below freezing for months, sometimes below zero for weeks. Sometimes below -10F for days (although that's becoming less common). These are legitimate questions. We're not going to find common ground, that's OK. Let's just stop circling around each other and/or worrying about it. Cheers.
