It’s not even close to what fuel source is significantly more reliable and available in times of emergency. I live rural though multiple power outages a year from storms and blizzards. Gas can always be stored more easily as a backup fuel. Even traveling to get gas in fuel cans outside the devastated area is significantly easy to transport and store.
You can add 2 gallons of gas along the highway (or anywhere) in under 4 minutes and be on your way. Just think how the military or emergency vehicles operate outside the grid of civilization.
Even our farms fuel storage tanks have hand pumps in case of power failure.
Gasoline and diesel vehicles were designed in a world before electricity was even available to most rural Farms.
