Cheap energy = sprawl?

One of the smart growth measures used in New Jersey places the burden of new infrastructure on the new developments that need it.  If a new neighborhood needs an expensive extension off of the power grid, either the new neighbors should pay for it or maybe the neighborhood shouldn't get built.  But a change in policy might shift the burden of infrastructure for McMansions to the people who are already living in less inefficient ways.  Is this about finding appropriate policies for BPU or part of an ongoing fight against government efforts to shape the NJ landscape?
