>No, you don't need storage for multiple weeks You have seasonal, and inter-seasonal variability in a solar and wind output. You need to account for that, in an economy that requires orders of magnitude more energy then being provided by renewables and is still electrifing. What do you mean it's silly? I've seen a few articles now where a baseline required battery storage is on the order of weeks. What do you mean a few hours is all that's required? What if you have a multi-day cloudy, wind-still weather? What do you do then????? >size your panels for the seasonal minimum, attach batteries No. You need to over-provison even for minimum seasonal output, because even in seasonal minimum you still need to charge your batteries. Winter is very long. > only hours worth of batteries If you don't mind constant blanks during periods of prolonged reduced wind/solar output...then sure. I don't what 'few hours' means - there's a day-night cycle every single day. Multi-day and highly variable multi-weeks where solar and wind output is minimal or none are relatively common. Here's what should give you pause and maybe make you reexamine your confidence - nobody is actually building out a solar/wind/battery infrastructure - nobody. We're essentially expanding natural gas use and complementing it with solar/wind (there's a reason why Germany is singing multi-decade contracts to ship Russian natural gas, and why every natural gas company is pushing renewables). Natural gas is not a transitional technology to renewables. It's the end-state for renewables.
