It is easy to figure out what it is that consumes the most electric in your home. An energy monitor in your fuse panel works too.
If you have a remote cellular connection to your HVAC...turn it and off and watch your electric meter.
I did have all electric appliances in FL except for the swimming pool heater which ran on gas.
New refrigerators / freezers these days utilize much less electricity than older (greater than 10 years old).
New HVAC (2-3 years old) was much more efficient than the new one installed with the new house build around 1999, BUT not enough to leave it connected to a generator.
Worked better with solar panels in the old house. The large gas tank was buried but probably would have only worked for a few days with a generator.
I priced a 16 Kw generator for the basics in FL many years ago. Only issue related to the use of gas.
So personally would have used generator for essentials like lightning and refrigerators. Would have cooked on a grill outside and not turn on the AC for any reason.
Uncle in St. Petersburg just got his electric on yesterday.
For commercial it was a tank (large) of kerosene that worked better. Tested this in Texas for an office with two floors running the generator for 7 days post hurricane before needing fuel.
Personally would try to get off or lighten the load on the grid using multiple solar panels. Automator peer north of Tampa had solar panels for electricity installed and he keeps his AC on most of the time and sells his electric back to the utility company.
Another automator peer in DC spent some $60 k for solar panels and doesn't utilize his AC at all probably cuz he paid a lot for nothing.
