The process of generation of electricity does not pollute and water can later be used for irrigation, human consumption, etc. Hydroelectric energy contributes to the sustainability of our planet.

• Safety: hydropower is safe compared to nuclear energy and fossil fuels. Despite some accidents occurred in dams, usually hydroelectric power plants do not entail a great danger to humans.

Like other forms of electricity generation, hydropower uses a turbine to help generate electricity; using the energy of falling or flowing water to turn the blades. ]]> 2018-01-25 18:10:32 UTC https://padlet.com/157892/tsvlzivawy3m/wish/224792501 157892 https://padlet.com/157892/tsvlzivawy3m/wish/224793950 A renewable resource is an organic natural resource which can replenish to overcome usage and consumption, either through biological reproduction or other naturally reoccurring processes. ]]> 2018-01-25 18:12:53 UTC https://padlet.com/157892/tsvlzivawy3m/wish/224793950 157892 https://padlet.com/157892/tsvlzivawy3m/wish/224794011  impoundment, diversion, and pumped storage. Some hydropower plants use dams and some do not. ]]> 2018-01-25 18:13:01 UTC https://padlet.com/157892/tsvlzivawy3m/wish/224794011 157892 https://padlet.com/157892/tsvlzivawy3m/wish/224796217 Hydropower plants capture the energy of falling water to generate electricity. A turbine converts the kinetic energy of falling water into mechanical energy. Then a generator converts the mechanical energy from the turbine into electrical energy.]]> 2018-01-25 18:16:46 UTC https://padlet.com/157892/tsvlzivawy3m/wish/224796217 157892 https://padlet.com/157892/tsvlzivawy3m/wish/224796332  Hydropower represents about 16% (International Energy Agency) of total electricity production.

Environmental impact: before producing hydropower it is necessary to build a dam, changing water levels and flooding large areas. It is also necessary to build roads and power lines. All that a strong impact on wildlife and the ecosystem.

Displaced people: the construction of a large dam often requires that entire towns move out of the area. In the construction of the Three Gorges Dam it is estimated than 1.2 million people were displaced.

Expensive: building a dam requires a very important initial investment

Accidents: in the past old dams often suffered breaches which led to floods and deaths.
