This is a niche thing and not really a matter of controversy, so don't click unless you like construction, engineering, and green energy projects.
Kaukauna Utilities, working with Madison's Boldt Construction, is rebuilding and renovating the Badger Hydro generating station (on the Fox River), which has been producing electricity for more than 100 years. They did a fish rescue, and are saving some of the old stonework done by the original builders. All very cool.
I couldn't find more pictures of the project on Boldt's web pages -- maybe they'll post some in the future.
