I completely agree you can build hardy solar/wind generation (i.e. runs in winter), however, the sun still sets each day, and wind is intermittent and unpredict

I completely agree you can build hardy solar/wind generation (i.e. runs in winter), however, the sun still sets each day, and wind is intermittent and unpredictable. until there is a revolution in battery technology, relying on those two sources (without others types of generation) will result in large electricity price spikes.
