   This really depends how the transporter works, and which laws of physics   
   one chooses to ignore.   
      
   One could hypothesise a transporter that works by dismantling the   
   thing/person to be transported where they currently are, and using atoms   
   available at the destination to construct a duplicate. With such a   
   system, there is no net transfer of matter from the ground to   
   spacecraft, or vice versa, so no reason for the energy requirements to   
   differ. Indeed, there's no obvious energy requirement - just an entropy   
   consideration.
