How Does Hydroelectric Power Work

Althoug hydroelectric dams have considerabley fewer emissions than thermal power plants the blocked water in the dam does cause the release of methane into the atmosphere.

How does hydroelectric power work. Read how power distribution grids work to learn more about power line transmission outflow used water is carried through pipelines called tailraces and re enters the river downstream. Actually hydroelectric and coal fired power plants produce electricity in a similar way. Hydroelectric energy is produced when the kinetic energy of water is converted into electricity using a hydro turbine generator. Sundance power systems designs installs environmentally sensitive micro hydro systems for folks in nc sc ga tn.

The three phases of power being produced simultaneously plus a neutral or ground common to all three. Although the generation of hydropower does not emit air pollution or greenhouse gas emissions it can have negative environmental and social consequences. Green house gas emissions. Water constantly moves through a vast global cycle evaporating from lakes and oceans forming clouds precipitating as rain or snow then flowing back down to the ocean.

Hydropower is using water to power machinery or make electricity. Power lines out of every power plant come four wires. Hydroelectric energy how hydroelectricity works. Hydroelectric power is renewable.

How does hydroelectric generation work. Hydroplants range in size from micro hydros that power only a few homes to giant dams like hoover dam that provide electricity for millions of people. A small or large micro hydro turbine can power your home or office building by generating hydroelectric power from the energy of a stream s flow. Hydroelectric power does not contribute to air pollution.

Put very simply hydroelectric power is generated using flowing water to spin a turbine which turns a shaft that s connected to an electric generator. There are many advantages to using hydroelectric power but no form of producing energy is without its downfalls. The photo on the right shows the alexander hydroelectric plant on the wisconsin river a medium sized plant that produces enough electricity to serve about 8 000 people. Today harnessing the power of moving water to generate electricity known as hydroelectric power is the largest source of emissions free renewable electricity in the united states and worldwide.

More often than not hydroelectric dams are used to direct the water downward through the turbine in a way which can be controlled to maximise energy production. Hydroelectric power is highly local reducing dependence on outside sources of fuel. There are several methods for using water to power a hydro turbine generator but they each generally function in a relatively similar manner all using the same fundamental laws of physics. There s a lot of energy in water.
