I cannot have a well as I am in the city. I have stored up extra food but I need to do water as well. I can live without lights but living without the computer might put me in a real poor state of mind.
During a wind caused 48-hour power outage a couple years ago, my internet continued just fine. I powered the PC and DSL modem from an inverter off the troock. It was weird, I could Google but I had no lights in the house.
