My life doesn't change much at all when the power goes out. If the water goes out yes. Maybe I'm being naive, but I'm trusting the local water company is properly maintaining their big diesel backup generators. Even so, I have water stored. I've also got enough solar panels to recharge my cellphone, my laptop, my radios... whichever communication systems are working.
It helps I live a mild California climate where heat and cold are not a threat to life. I like to believe I'm ready for the next big earthquake. My grandma lived in a place with a harsh winter climate. Her house had no plumbing so she never had to worry about the pipes freezing. Her winter comfort depended on the wood stove in the kitchen. Life without electricity would be easier for me than that.
