I like propane (clean) but it is lower energy density, and portable NG is mostly not practical..... so I can see doing a basic task in Cali:Not until 2028 and then only gas generators. Propane (and I’m guessing NG) and diesel are exempt. AND it only prohibits sale in CA, not use. Buy it out of state and you're good to go.
2023: Contractor shows up to do a small task, and runs a Honda suitcase gasoline generator, that next-door neighbour can't hear running.
2029: Same contractor, same task, 20kw diesel that can be heard blocks away......
Careful what you wish for.....
