Do you have circuit breakers? Turn them all off, starting with the main breaker- then starting w/main breaker turn each one on- that resets the breaker box. Fuse box? Check for blown fuses-they may look like shot gun cartridges-try those first (by exchanging them-you may have round glass ones-if so, they often turn color in the center-replace. Is your service underground? (call electric co). Service overhead? Look for downed wire. None of this matters if you are using too much power and your ele. System won't handle-that means get an upgrade to hold it or cut down on service used that controls those items. It can be either the electric company or private electrician that makes this work. Usually, if the ele co cuts your service you will have no power.
If the power is completely cut from your home, I think it will be prudent for you to contact your insurance agent who will then contact the relevant authority to come and rectify the situation as first as they could.
