We all work with the same laws of physics. That’s why they’re laws, not guidelines. We deal with Ohm’s Law, Shannon’s Law, Cole’s Law (thinly sliced cabbage), and others. And one of the immutable laws of electronics is that power consumption is proportional to voltage. Raise the voltage, and you raise the power consumption, all other things being equal. And of course, that works the other way, too. Lower voltages reduce power. Very tidy.
So why, oh why, do chipmakers have such a hard time reducing the power consumption of their microprocessors, microcontrollers, DRAMs, and other devices? Just lower the voltage! Did you not attend Electronics 101? How hard can that be?
