The sun is always shining somewhere on earth, so maybe it's possible [1] to connect all our grids together and transmit power from the light side to the dark side. Whether this is cheaper than buffering the power in huge energy storage systems, I have no idea.

The choice is between systems we know how to build right now and imaginary systems that may not ever materialize.
