We are called daily by folks who believe the world will soon fall into changes such that there will be no more utility power available. Reasons given include imminent earth polar shift, global computer failures, nuclear war and other forms of war, famine, and social disruption or other end to the world scenarios. I am not qualified in most of those areas to know who might be correct, but I reject any beliefs that embody racism or that make war or violence more likely to occur.
Solar electricity is indeed one of the most survivable energy technologies.
We can have enough food for our needs and to share and we can have the equipment to deal with power outages and failures of customary services. We can be prepared to the extent that we do not depend on outside services for our needs moment by moment. I have been amazed to watch civilized city dwellers get into miserable condition and have to leave their homes because a storm knocks power out for 2 or 3 days. But today we cannot just connect a solar electric system to an existing U.S. grid powered home that typically consumes 1000 to several thousand kilowatt hours a month. Converting an existing utility powered home to solar generated electricity requires first, redesigning radical energy conservation into the whole building.
