I heard that lowering the temperature of a semiconductor reduces power consumption, so why is that?

A. 1

If the temperature increases, the resistance increases.
This is because higher resistance increases power consumption.

OK

A. 2

When the temperature of a semiconductor increases, free electrons collide
Low temperatures reduce collisions and make it easier to move.
So you have less power consumption.

OK

A. 3

As the temperature rises, molecular motion becomes active.
This story is interrupted by molecular motion when an electric current is about to flow.
So if the temperature is low, you can reduce power consumption.
