I would immediately do a check to see if it was just our power or if it was everything. If my car wouldn't start then I would know it would be time to batten down the hatches....and within 5 minutes I would be at a friends house to tell them something was wrong and start packing up food and supplies and then get over to my house. After that I can't say cause don't want the entire world to know how big of a group we are. Safety in numbers though.
