Yes, but a single total energy doesn't mean anything. It's like me 
telling you that there's a single rock in the Himalayas that has 
gravitational potential energy of -10.234 megajoules.

It sounds like you might need to do some background textbook reading on 
molecular simulations and computational chemistry in general :-)
