> Summary: If energy is free and doesn't impact anything then of course you would want to use more of it.

I'm not convinced if this is always the case. I'm sure this is already a topic of interest in psychology but I guess that unless there is a reward for using the energy there wouldn't be consumption on the individual level.

As I'm writing this my CPU is at 2% and GPU at 1% utilization. I'm not actively looking for ways to utilize this even though it's (for the sake of argument) free.
