A power outage, however brief, causes a lot of consternation. Lights go out, computers are down, refrigeration ceases and life as we know it with all our modern conveniences grinds to a halt. This happened in our city recently during a busy lunchtime, disrupting the schedules of thousands of people who were having their noon break. Restaurants and other enterprises lost business and customers went hungry. Happily, the power outage lasted only a short time, but long enough to remind everyone how dependent we are upon the power grid that supplies our communities.
