If you read the Energy Tutorial Document:

Rather than slowing our machines down below their natural speeds, we prefer to run asynchronously and to arrange that our computers simply stop when waiting for stimuli such as data or commands from the outside world or from other computers. The computer is only drawing power when it is actually executing code; when waiting, it is drawing only leakage. The energy required to stop or start one of our computers is negligible, on the order of a handful of inverters changing state; an amount of energy measured in femtoJoules.
