Task energy is a more reasonable argument than whinging about how some people care so much about power. Everyone cares about power, at a fairly similar level - maybe 2-4x differences, but not 10x. And most of the ones who care underestimate how rarely their machine is actually fully busy. Idle power is probably more interesting than even task power, for anything other than an unusually busy server or cloud hypervisor.
