As chips become smaller and faster, they dissipate more heat, which is energy that is entirely wasted. By some estimates the difference between the amount of energy required to carry out a computation and the amount that today’s computers actually use, is some eight orders of magnitude. Clearly, there is room for improvement. -linkArticle commenting on reversible computing a form of computing that could allow for ultra energy efficient computation.
