I live in an apartment and had to go without electricity for 10 days in 2003 due to an ice storm. I still had my gas stove and could heat the apartment. I worked at a shelter. Some people would come to the shelter for part of the day to stay warm and go home at night. At night I slept without any heat on. I have a nice sleeping bag and I am accustomed to camping many days at a time in the winter. My windows are not in excellent shape so I have a roll of 6 mil plastic sheeting in my emergency kit that I can cover the windows with to reduce the draftyness. Without my gas stove I think I could use candle power to add a little heat and light. I have about a bazillion candles from yard sales.
