It is just as well as their journey becomes increasingly perilous.  They soon find themselves caught up in a war with an army that is led by people with an agenda quite distinct to theirs; these people see the lack of electricity as an opportunity to become hugely wealthy emperors within the new reality.
The power workers convoy becomes ever bigger and better armed which is just as well.  They find themselves fighting those of ill intent increasingly and had so far come out on top on every occasion. Never the less their focus remains undaunted reaching Florida and starting over.
