The idea is not, that you can go all renewable by tomorrow, but that you can work towards it.
So yes, you probably will have to invest in the energy grid.
And the lack of suitable rivers is a problem for conventional pump power plants, but there are concepts to do the same with artifical lakes on different heights.
Then there is hydrogen.
Energy costly to create, but the idea is, that solar energy is dirt cheap, once you have the plants.
And a tons of other potential technology.
So again, yes. Not really all market ready and exactly doable by tomorrow, but will be soon.
Sooner the more it gets invested into it, because there are no laws of physics hindering it.
Only lack of momentum due to the lazyness because of cheap fossil energy for "free"
