Did you note somewhere in this piece that shifting "primary" energy (which I wish we didn't track at all) from heat sources to electricity sources creates large efficiency gains? (Going the other way, generating heat from electricity is less efficient than generating it by burning hydrocarbons.)
When you say you need 6 kW of storage per kW of output, do you mean the baseload output to the grid? And 40 hours would mean 40 kWh for the same kW of baseload output? Would this also imply 7kW of solar panels (6 to charge, 1 for output at the time)?
no, as I understand, the requirement is 6 kW for 40 hours of storage per kW of baseload output, or 6x40=240 kWh of storage per kW of baseload output. I don't know what that means in terms of # of solar panels.

Thanks, so a bit over a week of output storage in either case! That will add up in a hurry.
Very interesting. I've also long been a fan of these "hairy" charts that show forecasts at different times vs actual.. Good way to stay humble!
Keep up the good work 💚 🥃
