Then the most important factor: wind and PV power have extremely low surface power density (how many watts from square meter), and they have very low capacity factor (percentage of operating at full power during a year).

In practical terms this means to replace one MW of fossil or nuclear power plant with wind or solar you need to occupy 50-200x larger area, and then 3-8x more for surplus capacity, and then double that in energy storage.

All that area eventually means waste.
