Hydropower Doesn't Count as Clean Energy
By Sarah Phelan, Earth Island Journal
Opponents of dams have long argued against putting barriers in the natural flow of a river. Dams, they point out, prevent endangered fish from migrating, alter ecosystems, and threaten the livelihoods of local communities.

Native Americans, fishing communities, and environmentalists have made these arguments in their quest to decommission four dams on Klamath River, which runs from southwest Oregon to the coast of California. But with California requiring a 25 percent reduction in the state's carbon dioxide emissions by 2020, clean energy has suddenly entered the Klamath dam debate.

Bill Fehrman, president of PacifiCorp, the hydropower company that owns these Klamath dams, says replacing the power from these dams "could result in adding combustion emissions to the environment."

Meanwhile, across the border in Canada, Hydro-Québec, the world's biggest producer of hydropower, claims that "compared with other generating options, hydropower emits very little greenhouse gas," thus "contributing significantly to the fight against climate change."

Maybe not. Recent reports on methane emissions suggest that dams are anything but carbon-neutral.
