Information theory and the second law of thermodynamics dictate that a logical operation in a computer must consume a minimum amount of energy. Today's computers consume a million times more energy per operation than this limit, but magnetic computers with no moving electrons could theoretically operate at the minimum energy, called the Landauer limit, according to electrical engineers.
