What is Hydropower and what makes it renewable?
Hydropower is a renewable source of power used throughout the world. It uses the force of water to generate power sustainably. A big concrete wall is built in a fast flowing river and water builds up behind it all the while the pressure is building up. As the energy level rises to a maximum, the water is released and as the fast moving water passes through turbines which then convert the waters energy into power. It works when water I channeled into water turbines. The force of the moving water, makes the turbine blades move and powers an electrical generator, which converts the power into energy. Hydropower is the most efficient and advanced way of making renewable power and is used in more than 170 countries worldwide. Hydropower is renewable because after the water has made its way through the hydropower station in continues downstream to the sea. At sea level it evaporates because of the heat. It then rises up through the atmosphere and turns into clouds as the air cools. The clouds then rise which causes more condensation, which then results rain. The rain then falls into the rivers again where the cycle begins again.
How is Hydropower used in Australia?
Australia has over 100 hydro power stations and a total capacity of 8GW. There aren’t any more useable major rivers, which we can dam now unfortunately. All the opportunities have already been realized. In Tasmania there are 30 hydropower stations.
What are some of the advantages of using hydropower, and disadvantages?
Here are some of the advantages.
• Once a dam is constructed it provides a constant infinite source of energy.
• If energy is not needed you can shut the sluice gates and the energy can be stored for when it is needed.
• The lake behind the dam can be used for water sports such as wake boarding etc.
• When in use the electricity made by the dam does not produce greenhouse gases that harm the environment.
• Is completely
