Stand-by generators for power generation are the safest way to provide electricity in case of a black out. Once it is installed properly the stand by generator will kick into action automatically even if you are asleep or on vacation. Portable diesel generators have to be refilled every few hours and they have to be placed far enough from the house as well.
