Nice ... you got your picture from "treehugger.com".

Can you identify:

A) What sort of works is attached to those smokestacks?

B) What is the chemistry of the plume coming from them?

C) Under what conditions was that picture taken?

I'll give you a hint, though: that plume looks like water vapor, to me.

I searched “power plant smokestack” and that image was right at the top of the list. Didn’t dig any further, as I thought it got the message across.

Water vapor is invisible. Those are man-made clouds with net global cooling properties. Rainfall will be measurably higher 20 miles downwind of a power plant.

But... don't you know that water vapor is a greenhouse gas? It's way worse than CO2, by orders of magnitudes! That just can't be good for the environment!

There’s one more thing you forgot to ask:

What was the outdoor air temperature and relative humidity/dewpoint at the time the photo was taken?
