How do large hydro plant emissions compare with fossil fuel power plants?

Large hydropower reservoirs in the tropics can have a higher global warming impact per kilowatthour generated than fossil fuels, including coal. Philip Fearnside, of Brazilian government research institute INPA, estimates that in 1990 the warming impact of hydropower dams in the Amazon was equal to that of between 3 and 54 natural gas plants generating the same amount of energy.
