There are countries running on 95%+ renewable electricity right now[1]. Including wind, hydro, solar, geothermal and biomass. Humanity keeps neglecting what is already proved to work. Because politics? Coal and gas are cheaper options? Environment is not considered in the equation?

That list ignores that countries trade electricity. If, say, Germany produces a lot of electricity by renewables it can sell the excess to France (which has lots of nuclear). If Germany is low on electricity, it can buy from is neighbors. The system as a whole is nowhere near 90%.

The one exception are probably countries that have all hydro and biomass.

You created a straw man. There are 10 countries that fit the 95%+ criteria, all of them probably have excess of production and have 0 interest in buying power. But yeah, what you say could theorically happen.
