solar-thermal is only good for very warm an sunny regions, photovoltaic works even in Arctic regions batteries make quick progress as well so storage will be super cheap in a few years.

Here we got even some snow as well. Guess what happens once the sun come out?
The snow slides off the black, wet glass-like surface of the solar panels. Efficiency also goes up if it's cold.
On a national level you always got an energy mix. Solar with wind and biomass and hydro and geothermic and fossil fuel.
