Microcontrollers run 100% of the time even while sleeping.

Nah, some MCUs have low power modes.
ESP32 has 5 of them, from disabling fancy features, throttling the clock, even delegating to an ultra low power coprocessor, or just going to sleep until a pin wakes it up again. It can go from 240mA to 150uA and still process things, or sleep for only 5uA.

Nah, Sleeping != Low power mode. The now obsolete ATmega328 has a low power mode.
