Dear Bo,
NAMDEnergy is not fully implemented in VMD 1.8.3. If you want to use it
from the console, you should run the commands
package require namdenergy

to get usage instructions. A more mature version of NAMDEnergy is
included in VMD 1.8.4; there is also a GUI available in this version.
You can download this version from the VMD website.

However, I am curious what you mean by saying the energy information is
in a ---.log file. If all you want to do is extract energy information
from a preexisting log file, you are better off just using existing
shell tools (I can give you more details if you need). NAMDEnergy is
designed to do new simulations to calculate the energies of subsystems,
which cannot be obtained from the logfile of a prior run.
