Idunno, Hell could have been a potential source of geothermal energy.

Or maybe it could aid in the discovery in previously unknown energy production methods.

Now there’s a fun moral dilemma. Is it ethical to generate electricity with the torment of the damned if it replaces polluting power plants and they’d be tormented anyway?

I mean, they're gonna be tormented either way so why not make that useful...

I was playing at the DOOM (2016) scenario though.
