Dare I suggest Problem Analysis?

If people have a problem requiring communications in the event of a 
power failure, then it is up to them to ensure that their solution 
(whatever it might be - batteries are probably only one solution option) 
is viable and current. Insisting on a specific technology solution to an 
ill-defined problem is fraught with danger and risk.

A question: Taking bush fires as an example, what makes communications 
more important than say water, mobility, radios, fire fighting 
capability, plants close to the house, fire proof shelters etc etc. None 
of these issues have mandatory solutions, why should communications?
