Pollution
Everything is so clean. Too clean. The answer to inefficient power production is often just to produce more fuel & build bigger power generators. Even the waste that's produced (if any) is usually in the form of objects or liquids that can be voided or indefinitely stored (or even turned into something useful).
At least, that's been my experience.
The closest thing I've seen to an unavoidable environmental impact is the sickness effect caused by MFR's sludge boilers. You have to plan those carefully so as to avoid the sickness caused by using them.
I asked a similar question before, but it's been a while, so I was wondering if there has been any movement toward that kind of an unavoidable environmental pollution/effect from power producers.
Some off the cuff ideas are - smog (world gets slightly darker near certain power plants, & maybe a slight sickness effect), random occasional additions of some kind of soot blocks nearby, etc.
EDIT: So I've been a babe in swaddling by playing only the published modpacks, apparently. Here are some mods from the comments that potentially include something of what I was talking about:
