An interesting possible is the grid becoming smaller. Neighborhood scale.
In many places from Central Europe and further north dealing with arctic cold spells and dunkelflautes are near impossible for a home solar and storage setup.
But you also don’t want to pay for a continental scale grid the remaining 51 weeks.
So in your neighborhood add some wind power and a good old trusty diesel/gas turbine running on carbon neutral fuel and keep the costs to a minimum.
