What you should think of this is
... nuke them from orbit. And then, nuke them again to make sure.

Creating energy, specifically electricity or other motive forces, requires a difference in temperature. The higher the difference in temperature, the more efficient and easy it is to create power.

The human is not a good source of power. Further, the human body needs the heat and the electric energy running through it. Tapping off of that alters the body and decreases its functioning.

So, if they are using body temperatures to create electricity, they can do the same by putting whatever it is out in the sun light and get more electricity with the same stuff. It is actually one of the engineering problems, if ever solved, would change the world. To use low grade heat to produce electricity. (with something that doesn't cost more than you would ever get out of it.)

And, the name "Institute of Human Obsolescence" is abhorrent.
In order to think such stupidity, you must assume that humans are only on this planet to make things in factories.
