How do we cope when our aging grid isn't as dependable as it used to be? What if there is an earthquake, flood or hurricane? How do we charge a cell phone, tablet or other device?

It is important to remember that in an extreme emergency cell towers may be down so communications may be impossible for a while anyway. Likewise, if the Internet is down you won't be able to access websites. However, cell phones can still be useful as lights and certain apps may still work.
