Energy conservation is the reduction of quantity of
energy used. Energy conservation supports the eco friendly lifestyle by
providing energy, which saves your money and at the same time saves the
earth. When you decrease the amount of energy you use you automatically make
efforts to reduce increasing global warming.
of Energy Conservation :
Solar Energy :
Solar power uses the sun's energy and
light to provide heat, light, and electricity for homes. It is the primary
source of all energy forms on the earth. It is one such energy which helps
in maintaining the ecological balance through the process of photosynthesis
and green house effect. We have been using sun to dry clothes and boil food
for generations. But now number of techno powers which have been developed
to make full use of solar energy such as : -
Photovoltaic systems :
By these systems the electricity
could be produced directly from the sunlight.
Solar Process Space heating and cooling :
It is the
commercial and industrial use of sun's heat.
Solar Hot Water :
The process to heat water with the
Solar Power plants :
Producing electricity bu using the
Passive Solar heating and daylighting :
Use solar energy
to heat buildings.
Wind energy :
Wind energy is often used to generate the mechanical power or the
electricity. In the country like India, wind energy holds the great
importance because of large hilly, coastal and desert areas. In the rural
areas it is used to pump water and grind grain. The benefit of wind energy
is that it is fully pollution free and is eco friendly too. It costs low and
the generation of power is continuous. It is the most effective way to
conserve the energy and prevent the environment.
Geothermal Energy :
Geothermal energy is used in the
form of thermal energy, electrical energy, nuclear energy, mechanical
energy, chemical energy and light energy. It uses heat energy from beneath
the surface of the earth. It was first used to produce electricity in the
Itlay in 1903. Geothermal energy has the major environment benefit as it
prevents air pollution. It is particularly important in the inland nations
such as Indian Oceans and the pacific regions. Energy generation from
geothermal sources is only possible in few places under unique geographic
Wave energy :
Ocean waves contain large amount of energy, which can be extracted through
Ocean winds, Ocean currents, Ocean Geothermal etc. if the barrage is built
across the river, electricity can be obtained by by the flow of water
through turbines as the tide rise and falls.
Hydroelectric energy :
Another renewable source of energy is the hydroelectric energy, which is
produced from fast flowing water. The process is pollution free. The
movement of water spins the turbines which in turn generate electricity.
Biomass energy :
Biomass is the plant and animal waste which is used as the energy. Biomass
energy like manure from livestock, plant waste etc can be used to generate
electricity, fuel, light, and heat. We get biomass energy directly from
plants and indirectly from the animal waste.
