Generators are surely the way to go - they are kind of expensive though and you need to know how to use one properly or they can cause death from the fumes.
 
Ours are installed in the garages of both our homes. We cant... WONT go with out lights. That drives me NUTS!  
If you can swing for a generator - it sure makes it a lot easier. They cut the power when a storm approaches - always. Its the safe thing to do. The power doesnt 'go out'. Counties in Florida PUT it out. 
Why would they do that? To protect children and idiots. 
Power lines and water dont mix well - causing death.  
They turn the power back on when they see all the lines are back up. So its not a matter of IF the power goes out - its going out. Its a matter of WHEN they choose to flip the switch. 
Like I said - few months shy of 20 yrs here - schooled well in this area.  
Generators ROCK!
