      There is no stable base for renewables.

      At noon in summer, renewables can produce >100% of energy consumption. The nuclear reactors would need to be shut off and turned back on a couple hours later, for the months from June to September.

      But nuclear cannot reactivate quick enough as solar production is winding down in the evening, nor can it shut down quick enough in the morning.

      It’s much, much cheaper to massively increase battery storage in order to store excess energy produced by renewables.

      In winter as of right now, there is not enough energy from renewables but this is hopefully subject to change over the next decade or so. If energy costs are high enough at night, companies will start building private battery storage to fill them during winter days. That way a large part of energy consumption can adapt to production.

      In case of energy droughts, gas power plants can be kept because they can turn on and shut down within minutes, making them the best at providing a varying base load.
