Question

Why does the power go out? (What causes it)?

Answer 1

when power lines fall down or get hit

Answer 2

usualy a transformer goes out or a power spike that means that there is to much power going through the power lines and it pops the circut at the substation.             <Please don't quote me on this.>

Answer 3

During thunderstorms, lightning can cause an overload of a transformer or of the Power 'Grid' resulting in a Power Failure as the Power Plant shuts down temporarily..

Heavy storms can also bring down power distribution lines.

Answer 4

Lots of diffrent reasons.  Anything from your own breaker thrown in your fuse box to a transformer burning out to any number of reasons for a fault in the power grid in your area.

I have seen transformers blow because of a squirrel getting on one and accidently getting grounded and electrocuted.
