Poland is going all on solar. People are enthusiastic about generating their own power, government had to step in and curb the enthusiasm.
Currently Solar PV output is incredibly unbalancing but hopefully batteries will offset that in the coming years
Put alternatively, better rates for consumers. How should one portion the cost of the electrical system as a whole to different groups of people? If someone seldom draws electricity from the grid, and only when it is likely more expensive how much should they pay? What about the limit where everyone is a prosumer and has this usage pattern?
