PPT ON
ENERGY CONSERVATION
ABOUT ENERGY•Energy can neither be
generatde nor destroyed.it can only be converted one
form to other.•For example.in a room
heater,electrical energy is converted to the thermal
energy.
WHY TO CONSERVE ENERGYWe have limited
fuels available on Earth
Our demand for energy is increasing day-by-day.
It is possible some day,most of fuels will be exhausted,and we will and we have to switch
over to alternate energy.
HOW WE CAN CONSERVE ENERGY conserving energy means
decreasing the amount of energy used while achieving similar
outcome of end use. Using less energy has lots of benefits you can
save money and help the enviroment.
using less energy help us to preserve these resources and
make them last longer in future.
IN SCHOOLo always switch off
lights and fans while going out of the class.o In computer lab, we should switch off the
computers before going out of the class.
AT HOMEwe should not keep light
and fan unnecessarily switched on.
watching interesting programs on TV is
interesting ,but afterwards ,tv should be swittched .
off.
IN PUBLIC AREAS stree light consume a lot of
energy,we can use the streetlights according to sunset and sunrise to
save power. installing solar powered street
light is another major option available to save electricity.
TUPES OF ENERGY
Renewable energy
Non-Renewable energy
Solar energy• Solar energy can be
converted into electrical energy by using solar
panel,or alternatively,be used as thermal energy
using solar water heaters,solar cookers etc.
WIND ENERG
Yo India is world ‘s third
largest producer of electricity generation using power by wind mills in indian ocean
and many other places.
HYDRO ENERGY Using dams,water is allowed to pass through turbine
blades,which produces electricity. In
India,after coal, most of the energy is produced by this
method.
