Anecdote: All 7 developers in my Houston team (semi-geographically scattered in the city) lost power; half for >24 hrs (it's 10-25 degrees F here for the last 2-3 days).
Most lost water for some stretch of time and some still don't have it.
I don't think any completely lost heat (most have gas) but at least one person found their gas fireplace they were hoping would heat them up when out of power didn't really work that well.
(I haven't found clear findings on what determines whether your fireplace net-warms or net-cools your house in super-cold weather (by sucking heat out of adjacent rooms and pulling cool air from the outside and sending hot air up your chimney). Pointers welcome.)
