A month? The area affected by the hurricane was without power for six months. Right then I realised how OPEC has this country by the short hairs. All you had to do was see almost every house running a generator. 
Some people also need either power or ice to keep their medicines properly cool. Insulin for diabetics for example.
Trying to get air circulation is good, but when you have 90% humidity going on with afternoon showers, it doesn't work so well. Lot's of houses were condemned by the county due to mold and not hurricane damage.
And don't forget, if you were lucky enough to have your house intact or easily repaired. you still had to go to work to kepp the momney coming in. You really want to keep the windows open during a crisis while you're away?
Ulmas, I was only referring to deliveries of gas for generators.
You are right though, people like diabetics who needed refrigerated meds had 2 choices, leave or die.
As for the homes, the blame lies with 2 groups of people, shoddy work by developers cranking out cookie cutter houses as cheaply as possible, and home buyers to stupid to realize that different environments require different building methods
Stick built plastic wrapped houses that may suit New England (The roofs don't shed or support the snow weight which means home owners have to rake or shovel their roofs after big storms) Suck in Fl. Well ventilated houses that might not be "Fungus factories" in Fl. are to expensive to heat up here.
The Old timer's built the way they did for reasons that post war "fast buck artists" don't give a sh#t about. You bought it, it's your problem.
