The only real downside to batteries is the cost. The upsides are vast. Beyond adding feasibility to solar and wind, batteries stabilize the grid. The ability to instantly absorb and output power in response to demand or a lack of demand is incredibly valuable.

I was somewhat gobsmacked when I learned there are electric stoves with integrated batteries (the batteries serving to reduce the maximum current draw for homes wired for limited current.)

And, when you think about it, it makes perfect sense. Stoves spend 90% of their time drawing 0 power.

A fridge would also do well to have a backup battery.
