... So it's not unlikely that for the typical user, the I7 is actually using much less power over the course of a day.

I over-simplified to make a point, which you reinforce here. My computer in 1995 had a 150W power supply. Computers these days typically have 450W power supplies or larger. My current PC has a 1200W power supply, which was unheard of back in the day. Overall, computers have grown more power hungry as efficiency has improved.
My overall point is that consumption of a resource will increase with increasing efficiency. Prove me wrong.
