Stationary power comprises traditional uses of electricity as well as power for heating and cooling of residential and commercial buildings presently provided by non-renewables (such as oil and gas) and does not include power for transportation (e.g. cars, trucks, buses, trains, air travel), although some forms of transportation ought to be powered by electricity such as trains.) The target should include plans to electrify most modes of public transit

Hydroelectric power from dams can produce carbon dioxide and methane due to decomposing plant material: http://www.newscientist.com/article/dn7046-hydroelectric-powers-dirty-se...
