My lifelong motto has always been "Independence is the Key!" If ever this is needed, it is in relation to emergency situations. This independence takes forethought, planning, purchasing supplies, and practice drills with your family. Also, remember to plan for your pets...and keep in mind extra supplies for those around you who may not be planning for themselves.
Many types of emergencies could leave you without electricity, heat, phone, or Internet service, so prepare accordingly. e.g. I have a couple first aid and medical books in my home since I wouldn't be able to look anything up online during a power outage.
