Argument: Unconventional hydropower reduces impact on river ecosystems
- Debate: Hydroelectric dams - pro argument.
Carrie Dolwick. "Tide Turns on Unconventional Hydropower". International Rivers. 15 Sept. 2007 - "The world's hydropower is now mostly produced by big, destructive dams. But new technological advances bring promise for a new wave of hydropower projects that leave rivers intact, flood no land, and produce energy around the clock. Tapping the nearly limitless power of the waves, tides, rivers, and constructed water-supply systems has the potential to supply much of the world's power cheaply, efficiently, and with few impacts."
