Why Do Computers Use So Much Energy?

An interesting Scientific American blog:

More generally, why do computers use so much energy in the first place? What are the fundamental physical laws governing the relationship between the precise computation a system runs and how much energy it requires? Can we make our computers more energy-efficient by redesigning how they implement their algorithms?
