Hydroelectric power generation

These appHcations require withdrawal of water from a source and subsequent treatment and conveyance to the point of use. Water is also used without being withdrawn from a source, eg, for navigation, recreation, wild and aquatic life propagation, hydroelectric-power generation, and waste assimilation and transport. The principal types of withdrawal uses and their average rates are given in Table 2. Some of these withdrawal rates represent multiple uses of the same water along main rivers in metropoHtan and industrialized areas.

Flash Steam Generation The most common type of hydroelectric power generation technique. Flash steam describes a system where a high temperature geothermal steam source can be used to directly drive a turbine. Also see Binary Cycle Generation. ... 

In a traditional tidal energy plant, a dam is constructed that captures tides as they flow inward. When the tide goes out, water behind the dam is released which powers a turbine in a manner similar to traditional hydroelectric power generation. These systems work best when there is a dramatic difference, at least 16 feet, between low tide and high tide.

The disadvantages of hydroelectric power generated through large-scale dam projects are its potential impact on wildlife and agriculture downstream from the dam, the possibility that it may displace the local population, and, ironically, greenhouse gas emissions ... 

The principal material required for a hydroelectric power facility is water (as energy supply and cooling). The potential impacts of hydroelectric power generation are primarily related to the impact of the physical structure, i.e., the dam, that is required for storage and management of the water used to power the turbines, and its effect on the local ecosystem in the river that has been converted to an electric power facility. Some negative impacts may include ...

The historical spread of dams with hydroelectric power generation capabilities is illustrated in Table 95.1. The dams have been grouped according to the decade in which they were reported to have been closed, or commissioned, rather than the date at which the reservoir created behind them filled.
