I can go either way, I guess.
I keep a couple jugs of water - one for cleaning, one for drinking (yes, it's filtered) - for small emergencies. I can always pee in the yard (hell, now that I have property, more than half the time I'm going outside to pee on my oak tree! Good lovin!), and crap in a pot and dig a hole in the yard. Of course, I have a killer environment to chill in, and I have books I can read, if there's a blackout. But in the summer, I'd go for electricity.
Another perk of living alone is that in either case, you don't have to worry about others pissing and moaning, or/and screwing up the order of things. Sweet jesus.
