Hydro gases.

You probably think of hydroelectric power as fairly benign from an environmental perspective. If so, you're wrong, at least with regard to greenhouse gases. "Drifting vegetation gets caught in dam reservoirs and produces massive amounts of methane when it rots." Apparently it's a big problem.

Who knew? I knew that dams were ecological terrors in other ways, but I certainly never thought of them as greenhouse gas producers.
