Study claims hydroelectric dams hurt climate more than oil http://apocadocs.com/s.pl?1278343636
Hydroelectric power is normally listed in the same breath as solar, wind and wave as a world-saving renewable energy source. But a study from Brazil's National Institute for Research in the Amazon claims that it could be considerably more damaging to the atmosphere than generating the same amount of energy from oil.
The study, which is due to be published in Mitigation and Adaptation Strategies for Global Change, asserts that Hydroelectric's "green" image is false and that traditional dam-based hydroelectric power generation systems could be releasing significant amounts of methane into the environment, thanks to the rotting vegetation submerged when the reservoir floods.
