That's not correct. For ordinary computers there is Landauer's principle, which gives a theoretical lower limit for the energy needed for computation [0]. I say "ordinary computers" because other comments mentioned "reversible computers" for which this limit doesn't apply. According to the linked wikipedia page, this theoretical limit is around a billion times smaller than current computers use for an operation, so you may call me pedantic.
