The Path Forward: Balancing Energy and Environment

Te futury of major dams lies lies note in choosing between hydropower development andd ecosystem conservation, but in finding experimentate approaches that recoverze both the value of reconvelable energiy and thee irreplaceveable importance of healty river ecosystems.
