It would only be considered 'wasted' if energy was free. But energy is not free, and thus choosing how to use compute resources is still important.
e.g. I own a few high powered workstations for fluid dynamics computations. If energy was free, I would be just running 'what-if' solves all the time just for the hell of it. But because energy isn't free, they stay in sleep unless I need them for what is deemed 'necessary' for research.
