An outage, or “blackout,” occurs when something interrupts the flow of electricity to the end-user, and an outage can affect a few homes or an entire city. With improved technology, outages are less common than they once were, but they still happen—sometimes lasting for days. Most of the time, there’s not much a homeowner can do to prevent an outage, though you could invest in a reliable personal generator that produces a limited amount of electricity until the power comes back on.
