Water Electricity

By Marengo

A great way to create energy is with water. Fresh water is a limited supply resource like fossil fuels but there is great amounts of salt water. Electricity could still be produced with salt water. The way the energy is created is when a liquid, like water, comes in contact with a solid. That solid surface becomes charged with a thin layer of energy, and when the water is forced through a channel, ions with an opposite charge pass and the other ions stay behind. So the result of the channel are opposite at one end and positive at the other, like a battery. If the channel is connected by a wire, then the current flows. An individual channel current is very small but with parallel channels more energy can be created.

Water electricity is generated by hydropower. Most hydroelectric power is obtained from damned water while using a water turbine and a generator. Water electricity powers 20% of all the world's energy. Norway produces virtually all its energy from hydroelectricity,while Iceland has 83% produced by water, Australia has 67%. Canada, the world's largest water electricity producer, generates 70% of its power from water.



Water electricity is also very easy to manage. If no one is working with the water plant, the electricity can still be produced with nobody there.



Water electriciy is a great way to get energy because it's easily renewable and powerful.
