I retired from an electric and gas company 13 years ago and back then the CO. that I worked for took security very seriously. Some companies didn't and to this day some are lax.
When I built this house which in this area almost everything is electric I told the contractor I wanted everything Propane, there isn't any naturel gas near here. He looked at me like I was crazy. The only things I really need electricity for is my well, septic system and heater fan.
I haven't bought a generator yet but its high up on the list.
