While there are only a couple of scenarios where it seems likely the grid will all but disappear, they have the potential to most seriously damage our way of life. A terrorist attack on our electrical infrastructure would leave us with at least the ability to rebuild and remain in communication with each other. This level of communication would probably not include the ability to contact family and friends in other states, or for that matter, in other counties. A nuclear strike or an EMP strike (which is also likely nuclear in nature) could effectively wipe out all electronic devices. I’m still investigating if that applies only to active devices or all devices.
In the event that our communications systems are damaged at a larger-than-local level, there may still be some options. These options come into play when our families are not together at the time of the event. For instance, children are at school, adults are at work, and so on. Preparing for such an event means planning for alternate communication methods. Plural. There’s a saying in the community that I like. “Two is one, one is none, none is done.”
