Environmental costs of hydropower plants [PDF]

WIT Transactions on Ecology and the Environment, Vol 98, 2006
The balance between human activity and the environment has been destroyed for some time because of rapid development in all parts of the world. The coexistence of development and the environment is achieved by technical and economic approaches. The technical approach takes into account such factors as air pollution measures, conserving energy, and ...
