Nuclear can cover the gap at poles.

Anyway, nuclear power GENERATES heat and electricity, so it increases global temperature, while renewables are CUTTING part of solar energy, so they decrease global temperature.




The direct thermal energy output of human industry is small compared to the indirect effect of greenhouse gases:

Do you know why solar panels looks dark, almost black? Because they absorb as much solar as they can. IN real life if you cover surface with panels, albedo would decrease and system as a whole would absorb MORE solar energy. But part of absorbed energy would be converted to electricity and do some work. At the end it all would be heat, so on pure heat basis solar panels would increase temperature


Problem with solar panels is solvable: a special material to emit heat in a narrow infrared region, to which Earth atmosphere is transparent, is already invented in India. It will keep solar panels cool, which will increase their efficiency. Per watt price for this material is unknown for me.
