In case of a power outage consider being prepared with the following:
Alternative cooking methods: a portable cook stove or a camp stove will allow you to cook hot meals, but plan for adequate ventilation.
Alternative heat source
Wool blankets/sleeping bags to conserve body heat.
Cover windows with heavy curtains at sunset to retain heat and prevent cold from entering; remove at sunrise to take advantage of passive solar heat.
Stock up on water and canned meats, vegetables and fruits, to feed your family and share with a neighbor in an emergency.
