a power plant -a place where electrical energy

is obtained by converting some other form of

energy.

A power station (also referred to as

a generating station, power plant,

or powerhouse) is an industrial facility for

the generation of electric power

4/24

At the center of nearly all power stations is

a generator, a rotating machine that converts

mechanical energy into electrical energy by

creating relative motion between a magnetic

field and a conductor. The energy source

harnessed to turn the generator varies widely.

It depends chiefly on which fuels are easilyavailable and on the types of technology that

the power company has access to.

Nuclear

Nuclear power plants use a nuclear reactor's heat tooperate a steam turbine generator. About 20% of electricgeneration in the USA is produced by nuclear powerplants.

Nuclear power is produced by controlled (i.e.,non-explosive) nuclear reactions. Commercialand utility plants currently use nuclearfissionreactions to heat water to produce steam,which is then used to generate electricity.

In 2009, 13-14% of the world's electricity camefrom nuclear power.

Coal

A coal-fired power

station produces electricity by burning coal to

generate steam, and has the side-effect of

producing a large amount ofcarbon dioxide,

which is released from burning coal and

contributes to global warming. About 50% of

electric generation in the USA is produced bycoal fired power plants

Geothermal

Geothermal power plants use steam extractedfrom hot underground rocks.

Geothermal power is cost effective, reliable,

sustainable, and environmentally friendly, buthas historically been limited to areasneartectonic plate boundaries. Recenttechnological advances have dramaticallyexpanded the range and size of viableresources, especially for applications

Biomass

Biomass Fuelled Power Plants may be fuelled

by waste from sugar cane, municipal solid

waste, landfillmethane, or other forms

of biomass.

Steam Turbine

Steam turbine plants use the dynamic

pressure generated by expanding steam to

turn the blades of a turbine. Almost all large

non-hydro plants use this system. About 80%

of all electric power produced in the world is

by use of steam turbines.

Hydroelectricity

Dams built to produce hydroelectricity impound

a reservoir of water and release it through one or

more water turbines, connected to generators,

and generate electricity, from the energyprovided by difference in water level upstream

and downstream.

This was approximately 20% of the world'selectricity, and accounted for about 88% of

electricity from renewable sources.

Solar

Solar power is the generation

of electricity from sunlight. This can be direct

as with photovoltaics (PV), or indirect as

with concentrating solar power (CSP), where

the sun's energy is focused to boil water which

is then used to provide power. Solar power

provided 0.02% of the total world energyconsumption in 2008.

Wind

Wind power is the conversion of wind energy intoa useful form of energy, such as using windturbines to make electricity, wind mills formechanical power, wind pumps for pumping

water or drainage, or sails to propel ships. Wind turbines can be used to generate electricity

in areas with strong, steady winds,sometimes offshore. Many different designs have

been used in the past, but almost all modernturbines being produced today use a three-bladed, upwind design.
