Water power (Emma's glogster )

How does hydro power work?When water goes into a turbine (the turbine turns sort of like a wind genorator) which then that powers the genorator. The motion of that creats electricity. After the electricity is sent into a place where electricity is sent to homes.Advanteges and Disadvantages of Hydro power...- Once a dam is made electricity can be created at a constant rate - If electricity is not needed, the gates can be closed, stopping the making of electricity- The water can be saved for use so when the electricity damand is in hand the gates can open- Dams are designed to last many years so it can make electricity for decades- The lakes that form behined the dam can be used for water sports- Dams are extremely expensive to build and must be built to a very high standard- The high cost of dam construction means that they must operate for many decades to become profitable.- The flooding of large areas of land means that the natural environment is destroyed.- People living in villages and towns that are in the valley to be flooded, must move out. This means that they lose their farms and businesses. In some countries, people are forcibly removed so that hydro-power schemes can go ahead.- Although modern planning and design of dams is good, in the past old dams have been known to be breached (the dam gives under the weight of water in the lake). This has led to deaths and flooding.- Dams built blocking the progress of a river in one country usually means that the water supply from the same river in the following country is out of their control. This can lead to serious problems between neighbouring countries.
