Depending on where you are, that's pretty close to what's happened. Right now (4pm), the California ISO is generating 73% from renewables+hydro, 7% nuclear, and the balance gas. Naturally, the night replaces solar with gas. This is largely how California has reduced electricity emissions to their current levels.

Always gets me that the above is a no brainer. But people married to the argument that we can't have renewables until we solve the storage problem just refuse to even consider it.

Disconcerting.

And that nuclear power is just from a single plant!

NG is still extraordinarily high carbon. "A little better than coal (if you ignore the pipeline and wellhead losses)" is not something we can settle for given the seriousness of climate change. We need 24/7 low-carbon power. Fracked natural gas for entire nights (recall in winter nights are quite long) is not an option.
