I am an electrical engineer that mainly works on hydro plants but also have done some work on natural gas plants. The fact that this is so high is shocking to me. I guess the big culprit is coal plant cooling towers. The natural gas plants I've worked in don't even have cooling towers, any cooling water goes right back where it came from.
