law of conservation of energy and computing

A question I've been mulling over for weeks, and wondering who to ask:

Computers use electrical energy and produce heat. Is the heat produced by computers less than the electrical energy consumed (I would assume so, but would like a definite answer!) and if so, what is that residual energy "stored in" computing? What happens to the energy when say the result of the computing is erased? A lot of the computing is just lost to the environment in general as well, so what happens there?

Trying to wrap my head around the law of conservation of energy in this special case.
