Storing energy isn’t as difficult as it’s made out to be. There’s molten salt, water pumps, boiling/heated water, discarded batteries, even hauling weights up a tall tower.
I’d like to see every building with solar panels and a backup battery to decentralize the grid.
I have a feeling this is where the suburban and rural grids are going. Dense urban areas are likely still going to need power produced off site.
What I'm more interested in will be farms in whether they'll stay traditional producing food or convert solar farms where food production is not the main focus (see the hops farming solar panels for example).
It's not difficult, but it is expensive and inefficient. There are very few financially viable battery technologies on the market currently, and although incremental improvements are happening on that front, there are also roadblocks (lack of raw materials like cobalt, toxic metals, thermal runaway fire risks), we really need a big breakthrough before we'll see large adoption of batteries.
