Hydroelectricity

Hydroelectricity- [|Hydroelectriciy site]: **Advantages: **
 * Explanation: **
 *  hydroelectricity is an energy resource which is an example of the kinetic form of energy
 * hydroelectricity is a renewable energy resource because it uses the water cycle to generate electricity
 * the movement of water downstream creates kinetic energy which can be converted into electricity
 * A hydroelectric power plant converts this energy into electricity by forcing water, often in a dam, through a hydraulic turbine that is connected to a generator
 * the water is then let out of the turbine and released back into the stream or riverbed
 * it is a renewable resource

 * <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 15px; text-decoration: none; vertical-align: baseline;">it does not produce air pollution
