NEW DISCOVERY - Harnessing Power from Water Energy

NEW DISCOVERY -  Harnessing Power from Water Energy. Water is one of the most common chemical compounds on earth and the oceans provide 75% of the planet's surface. It is essential for life, and finding water on other planets is one of the main objectives of the scientific experiments conducted by NASA. The power of water through the use of waterwheels, was the first industrial process harnessed by human beings, which is used to power mills and cutting stone in ancient Egypt, the water energy is based out of the conversion of potential energy at the top of a well head to kinetic energy by the flow of water.

Water power is a renewable energy source, and is used mainly to generate electricity in the modern era through a process called hydroelectric generation, where the flow of water runs a turbine, which is used to power a generator . The United States is one of the world leaders in hydroelectric power generation, getting nearly 10% of its total power from hydroelectric plants, as the oil price increases and volatility in the Middle East sends shocks through market energy, consumer many more people are seeing the benefit of water power and hydroelectric plants, although the dam construction projects are expensive, and significant environmental impacts.

The power of water in the form of water wheels was first used in classical times to run the mills and stone cutting saws, which requires the placement of a coincidence of forms of water supply and resources being processed. Advances in orientation (especially the camera and sliding the transverse axis) allowed water wheels to be used for standing "mortar type" grain mills from the second century BC, and these films have been shown in set in the medieval years. The first American hydroelectric dam was opened in 1882, the hydroelectric dam was opened first in the U.S., a marked departure from coal plants. As the spread of electricity, the value of hydroelectric power increased, as electrical transmission allows the water energy is transmitted to places away from the head water of the dam.

Water power is the result of converting the potential energy of stored water "uphill" or a higher pressure level converted to kinetic energy, the conversion can be harnessed by water wheels or by electrical turbines. Because year after year, rainfall patterns are fairly stable, hydroelectric power is predictable. It does not require the burning of fossil fuels, on the other hand, once the plant is built, increasing its production is almost impossible, since the amount of energy that the water is determined by the weight of water and the flow rate or down the turbine. Naturally moving, fast flowing water in a deep river carries significant amounts of energy, the water current, and the steeper the slope, the easier access that water energy is - think of a waterfall as a good example.

While water energy is a clean, emits no energy source that does not come with zero environmental impact, hydroelectric plants require building dams, which create reservoirs and change the local environment, and can flood hundreds of miles squares; China Three Gorges will flood an area larger than the state of Nebraska as its reservoir
