....And that's why there's a lot of research and development in energy storage right now, including liquid air, compressed air, various gravity-based systems like EnergyVault, alternative battery chemistries, etc.... That and the commercialization of using hydrogen to eventually replace gas (they can be mixed together) for all its purposes (generation, heating, transportation, etc.) will be critical to reducing gas consumption, much like electrification is the key to reducing oil consumption.
Also, keep in mind that a lot of this will also be done on the demand-side, whether that's controlling the charging of electric vehicles or scheduling industrial processes to be done and buildings' HVAC systems to be used when renewable generation is highest / energy demand & prices are lowest.
I'm increasingly involved with a company that's involved in a lot of these emerging technologies, and there are going to be a lot of changes as they get deployed.
