Lots of low cost ways to have basic power these days....you'll spend less cluckers today than 5 or 10 years ago, that's for sure!
Food, shelter and heat are the biggies. And for me, communication and lighting are next. And even though I can make my own electricity, I still have Aladdin and regular oil lamps, multi fuel stoves, and a cool little heat powered charger for my ham radios.
Working on making my beer supply sustainable now :-)
