Hydro power

  1. 1. Hydro-power By Falco.Kirbyx
  2. 2. What is Hydro-power? <ul><li>Hydro-power uses the energy of moving, further more it turns the turbines and generators to make electricity. 20% of electricity word-wide is hydro-power. Hydro-power plants need large dams to produce electricity. </li></ul>
  3. 3. Where in the world is it Hydro-power being used? <ul><li>It is used in many countries.China is the largest producer of hydrolectricity. The three gorges dam is the biggest dam in the yangzet river is the largest scheme. Canada is the second largest producer of hydrolectricity. Hydro-power plants can be found in, France, Nepal, Brazil,Paraguay, Germany, Iceland, India, Norway, The U.S, The U.K, Russia, Japan and Turkey. In Australia has the Snowy Mountains River Scheme. </li></ul>
  4. 4. Plus Points <ul><li>A water plant will last much longer than a fossil fuel plant, so can be used longer. It takes less people to run a water plant, there for that makes it cheaper to run. Hydroelectric is clean and less dangerous nuclear power, and fossil fuel. It can be used to control floods, also it can be used to swim in or to go fishing in. We won’t run out of water because the hydrogen [which can be found in living or growing things ]  in the air and will turn into water h20. </li></ul>
  5. 5. Negetive points <ul><li>Hydro-power plants can destroy some habitats for fish and will stop salmon from spawning (having babies). Reservoirs can also change normal water temperatures, the flow of water and increase the amount of silt in the water. Carbon dioxide and methane can also form in reservoirs and be emitted into the atmosphere adding to the green house effect. </li></ul>
  6. 6. Host country <ul><li>Definite potential because Hong Kong is surrounded by water. But there is not much land and damning could destroy valuable land and displace people. </li></ul>
  7. 7. Home country <ul><li>Already in use (Snowy Mountains River Scheme). But already water is a scarce resource it would be better to harness sea water for those living by the sea. An alternative resource is need for the center of the country. </li></ul>
  8. 8. Where in the world could it be sited? <ul><li>Areas where there are lots of rain and snow will have more moving water which is need to make hydro-power. (Japan, America, Russia, Canada, Scandinavian countries). Places where water flows from a high mountain to the low areas are also ideal for sites (Switzerland). </li></ul>
  9. 9. What will stop it's use? <ul><li>If other energies become more efficient. If another reliable energy source is found. If the damage to the environment is too great. Not enough moving water. </li></ul>
  10. 10. Comprarative costs <ul><li>Larger the hydro power plant the cheaper it is to produce electricity. Hydroelectric is 1/3rd the cost of a fossil fuel, or nuclear power plant. </li></ul>
