  2. Hydro-Electricity Backgrounder • Hydro-electricity is energy created by falling water • The water must fall a considerable distance to have enough energy to push a heavy turbine and a generator • Dams provide this vertical distance

  3. Water Power Advantages • It is clean and renewable • It leaves no waste • The reservoirs that form behind dams offer recreational opportunities and provide drinking water • Dams may control flooding

  4. Water Power Disadvantages • Dam construction can disrupt existing land and river ecosystems • The newly created flood plain may displace a number of settled people • The cost of constructing a dam has soared • Hydroelectricity is an option limited to areas that have rivers and streams

Three Gorges Dam Backgrounder • 40 to 80 million people worldwide have been have been physically displaced, usually by being “flooded out”, by the construction of dams • With the completion of the Three Gorges Dam, an estimated 2 million people will be displaced • Most dams provide benefits for a country or region as a whole while the people who are most affected and bear the brunt of the costs usually live in the river valley or close to the river’s edge • The Three Gorges Dam , at more than 182 m high and 2.4 km wide, with a 640 km long reservoir will be one of the few man made structures visible from space

  15. Three Gorges Dam Issues Political • Countries not showing support, but Multinational Companies are. Economic • Provide inexpensive energy • Will help with economic development • Increase shipping into interior of China • Cost of $25 Billion

  16. Three Gorges Dam Issues Social • Will stop flooding and will save lives • Will displace 1 million to 2 million people • Loss of farming land (people will be moved to insufficient farm land) • Loss of cultural sites (ancient temples, monuments), burial grounds Environmental • Less coal needed • Change the ecosystem for the fish • May threaten endangered species • Lake will not allow for movement of wastes
