If your entire home/business is without power, check your circuit breakers. If any of them are off, turn them back ON. If any of them trip again, or if you're using fuses, call a licensed electrician.
If only part of your home or business is without power, there may have been an overload (too many appliances on the same circuit) or short circuit.
