Nobody would, but the nuclear and carbon lobbies like to use straw men models - combining things like laptop batteries with solar to "prove that you cant live without them" and these models leak into public discourse.
A fully green energy grid would most cost effectively comprise of:
* Solar (generally strongest when wind is low, ~5x cheaper per kwh than nuclear power)
* Wind (generally strongest when sun is low, ~5x cheaper than nuclear power)
* Large scale interconnected grids to offset intermittency.
* Batteries and pumped storage for short term storage (~90% roundtrip efficiency but expensive to store long term)
* Syngas for seasonal storage (~50% roundtrip efficiency but cheap to store long term).
