Hydroelectricity (Hydro Power)
Hydroelectricity is a form of hydropower and is the most widely used
form of renewable energy throughout the world. It produces no waste
and does not produce carbon dioxide (CO2) which is one of
the greenhouse gases.
power is generated by harnessing the power of moving water. Hydro
electricity extracted from water depends not only on the volume but
on the difference in height between the source and the water's
systems convert potential energy stored in water held at height into
kinetic energy movement to turn a turbine to produce electricity. A
micro hydro plant which is below a 100kW is an attractive means of
To benefit from
a hydro power system on a domestic scale, the water must be
relatively close to home or where the power will be used or to a
suitable grid connection. Hydroelectric systems can be connected to
the main electricity grid or as a part of a stand-alone (off-grid)
power system. In a grid connected system, unused energy generated
can be sold back to electricity companies.
In places where
there is no access to any main power connection, a micro hydro
system can provide a steady and reliable source of electricity for
lighting, electrical appliances, space and water heating.
produces no carbon dioxide or harmful emission in contrast to
burning of fossil fuels.
