I diagree, at current tech/time energy storage is the problem with peaky production methods like wong and solar.

You need capacity and quick spinup capacity for when demand occurs off peak production. Nuclear is the only green option with current tech for large scale. Fuel cells would be ideal when powered with electrolyzed h2 created by excess solar generation capacity but the tech isn’t there yet and we need something now.

Thermal energy storage and pumped hydro are both viable but spatially problimatic or expensive in the long term. IMO, micro grids with local solar as the source are where we should be going but local storage is an issue even where sun is abundant.
