Generating that amount of energy using nuclear would cost approximately $13.4 per person per day (IIRC ~3x what we're currently paying for it). Note that I have not included the cost to generate the energy in the $130 storage costs, but that cost is negligible compared to the $130 anyway.

The environmental damage would probably also be much less with nuclear, versus a ton of solar + wind + batteries. But there would be disaster danger. It is unclear to me how the danger of nuclear disaster would compare to the danger of running out of stored energy in a winter month.

How?

Since the costs of storage are currently so huge, it seems to me that if you want to go the solar + wind route, it makes sense to overprovision energy generation. That would reduce the amount of storage you need, and the extra energy during summer would be somewhat useful. Note however that you would need massive amounts of wind+solar.

For an average household to satisfy its electricity needs, it needs ~10 average size solar panels (assuming perfect storage). However, household electricity use is only 5% of our energy use. So to satisfy energy needs with solar, you need approximately 200 solar panels per household. Even if you round that down to 50 due to reduction in energy consumption and use of wind energy, it's still a lot. But the Netherlands is obviously not a very good country for solar. In countries like Australia, the numbers would look way better.
