Yeah but you said it was a "problem" - like I dunno, likely the excess energy start a fire or something? - whereas turning them off seems like it would reduce that to the system merely being less efficient than would otherwise be possible.

Anyway, definitely some kind of energy storage battery seems naively to me like it would be the best solution, even if used in conjunction with several forms of energy production (solar, wind, geothermal, maybe biomaterials etc.).

They do shut off ("curtail") renewable energy because it is a problem - excess power can destabilise the grid, causing brownouts and blackouts and also physically damage grid equipment like transformers and transmission lines over time.
