    With all the gasoline shortages in Florida I thought it would be interesting to crunch some numbers...

    I couldn't find any hard numbers for the vehicles leaving Florida but given the population ~3M would probably be on the high end. The primary reason for shortages is more than likely 'hoarding'...

    Electricity has a HUGE leg up there... it's kinda hard to 'hoard'.

    So how much electricity would it take to move ~3M EVs 500 miles? ~500GWh. FPL is capable of generating ~600GWh/day. The real trick would be ensuring that 3M people don't try to top up all at once...

    You can't hoard electrons, yes. But it's also difficult to stock up on an emergency supply of electrons in the event that electricity goes out (likely in a high-wind event like Irma).

    I was referring to evacuation BEFORE the storm. For getting power AFTER the storm solar PV is the answer.

    Sadly, many PV systems are grid-tied and suffer from outages like the rest of users. Hopefully more and more people have a backup battery or a disconnect so they can get running off solar during an outage.

    Consider this: if you have to evacuate, you are likely to sit in traffic quite a bit. An EV uses almost no power while sitting in traffic (I verified this myself in a massive gridlock we had here during an ice storm). Gasoline cars run out of gas while sitting and idling. So, a fully charged EV may be better in this case (just avoid use of the cabin heater). Remember, plug that sucker in.

    I suspect Florida's hurricane preparedness recommendations are similar to Texas's. Starting in the beginning of hurricane season - June - people are reminded and encouraged to stock up on supplies and keep their tanks full. Perhaps the preppers are vigilante about this. Many of us take the wait & see attitude. Many would drain their tank in a few days of normal to work driving.

    Last time I evacuated, things went like this. Left south of Houston for a 220 mile trip to San Antonio. It took 16 hours and only the last hour and a half were capable of "highway" speed. And not because I wasn't on a highway. We used the 40 gallon tank of the Suburban to refuel the 12 gallon tank of the Mustang. Wife was in the Mustang with the little dogs and AC. I was in the Suburban with the big dog & no AC. Temps in the high 90's. I'd split a bottle of water with the dog. People died from heat stroke on the side of the road. The wife had blisters on her foot from working the clutch for hours on end. As it turned out, the hurricane didn't come anywhere close. Houston hasn't recommended evacuating because of the wind threat of hurricanes since.

    Say you're evacuating Florida in the Tesla. You're supercharging. People are waiting for your stall. How much buffer and / or "hoard" do you charge to? Plan on waiting at the next supercharger. I not suggesting there even is a correct answer. Everyone's circumstances are different. Trying times for all. Good luck to everyone.
