hold back water that is then released through a turbine. The turbine’s spinning starts a generator that produces energy. Something that is unique about hydropower is that it has the ability to store energy. It starts as the same as a regular power plant‚ but instead of the turbine spinning forward‚ it spins backwards. The turbine pumps the water to a pool‚ like‚ area that stores the water when needed. If needed‚ the water is released back to the turbine‚ spinning it forward starting the generator. The

Wind Energy A turbine is machine that spins arounds catching energy that’s passing by. The huge rotor blades (propellers) on the front of a wind turbine are the "turbine" part. As wind passes by‚ the kinetic energy (energy of movement) it contains makes the blades spin around (usually quite slowly). The blades have a special curved shape so they capture as much energy from the wind as possible. Although we talk about "wind turbines‚" the turbine is only one of the three main

Electricity has become the main sources of domestic energy in Australia over the last 200 years and played an important role in today’s society‚ industry . In the early time when the British started to settle in Australia‚ firewood was the most important fuel. In 1831‚ Michael Faraday put forward the electromagnetic induction‚ which led to the development of electric generators and made the large amount of electricity supply become possible. After 1879 when the perfect light globe was designed

Steam Turbines The invention of the water turbine was so successful that eventually‚ the idea came about for extracting power from steam. Steam has one great advantage over water-it expands in volume with tremendous velocity. To be the most effective‚ a steam turbine must run at a very high speed. No wheel made can revolve at any speed approaching the velocity that a steam turbine can. By utilizing the kinetic energy of steam flow‚ the turbine could achieve a higher efficiency. As a result

Tidal power has great potential for future power and present energy consumption because of the massive size of our oceans. Using a combination of dams‚ fences‚ and turbines‚ many countries are utilizing the almost untapped resources of inexhaustible tidal power. Created due to the gravitational forces of the moon‚ the tides of the day are highly predictable and can be used incredibly efficiently. This type of energy

Similar to a wind turbine‚ many tidal stream generators rotate underwater and is driven by the swiftly moving dense water. Although not yet widely used‚ tidal power has potential for future electricity generation. Tides are more predictable than wind energy and solar power. Historically‚ tide mills have been used‚ both in Europe and on the Atlantic coast of the USA. The earliest occurrences
