Thankfully its an academic debate now anyway, because solar and wind prices are already much cheaper with no end to their continued improvement in sight. Has large scale energy storage been solved? I know there are a number of ways to do grid-scale storage, but are any of them scalable enough to power the entire country from solar and wind? Especially if another "storm of the century" (which seem to be happening more frequently now) reduces solar/wind output from a significant portion of the country so you need to draw deep into storage reserves.

> Has large scale energy storage been solved? There are numerous technologies which can currently provide large scale energy storage at cost which is currently competitive in many situations and due to drop rapidly once they are actually required and built in quantity. To mention a few: flow batteries, hydrogen production and generation, carbon neutral biomass fuel, heat storage and conversion batteries including molten salt, enhancement of existing hydro schemes, online EV fleet, active geothermal... besides you know if pushed, even the occasional emergency fossil fuel burn if unprepared. Nuclear plants are not known for their uptime during storms either. Current prices are detailed here, been dropping every year : https://www.lazard.com/perspective/levelized-cost-of-energy-and-levelized-cost-of-storage-2018/ https://www.lazard.com/perspective/levelized-cost-of-energy-...
