Depending on exactly what you're after, VMD offers the APBS plugin and
PMEPot plugin for calculating electrostatic potentials (through two
different methods), or the NAMDenergy plugin for calculating interaction
energies in the charmm or amber forcefields. You may want to look at the
descriptions of these plugins on the vmd plugin page
(http://www.ks.uiuc.edu/Research/vmd/plugins/) to see which (if any)
does what you want.
