3. WHAT IS ENERGY ? Energy lights our cities, powers our
vehicles, and runs machinery in factories. It warms and cools our
homes, cooks our food, plays our music, and gives us pictures on
television. Energy is defined as the ability or the capacity to do
work.
4. TYPES OF ENERGY RENEWABLE ENERGY: Renewable energy can be
generated continuously practically without decay of source. Some
examples are : Solar energy , Wind energy , Geothermal energy ,
Hydro energy. NON-RENEWABLE ENERGY: Non-renewable energy is energy
that comes from the ground and is not replaced in a relatively
short amount of time. e.g. energy generated from combustion of
fossil fuels , coal , gas etc.
5. Alternate Sources of Energy Wind Energy Hydroelectric Energy
Biomass Energy Solar energy
6. Wind Energy Wind energy is the kinetic energy associated
with the movement of atmospheric air. It has been used for hundreds
of years for sailing, grinding grain, and for irrigation. Wind
energy systems convert this kinetic energy to more useful forms of
power.
7. Hydro-electric Energy The energy in the flowing water can be
used to produce electricity. Waves result from the interaction of
the wind with the surface of the sea and represent a transfer of
energy from the wind to the sea. Energy can be extracted from tides
by creating a reservoir or basin behind a barrage and then passing
tidal waters through turbines in the barrage to generate
electricity.
8. Bio-mass energy Biomass is a renewable energy resource
derived from the carbonaceous waste of various human and natural
activities. It is derived from numerous sources, including the by-
products from the timber industry, agricultural crops, raw material
from the forest, major parts of household waste and wood.
9. Solar Energy Solar energy is the most readily available
source of energy. It does not belong to anybody and is, therefore,
free. It is also the most important of the non-conventional sources
of energy because it is non-polluting and, therefore, helps in
lessening the greenhouse effect.
10. WHY TO CONSERVE IT ? We have limited resources available on
earth. Our demands are continuously increasing day by day. It is
possible that someday most of the non- renewable resources will be
exhausted and we will have to switch over to alternate energy
11. We save our money when we save energy. We reduce pollution
when we save energy. We save our energy when we save energy.
12. WHAT WE CAN DO ? RECYCLE - compositing waste materials into
new products to prevent waste of potentially useful materials. Turn
off all electronic devices that are not in use. Not only turn them
off but try to remember to unplug them. You will be surprised how
much you will save with this simple step! Replace old light bulbs
with energy saving fluorescent bulbs. They may cost more, but will
save you much more in the long run.
13. At Home We should not keep lights unnecessarily switched
on. Reduce the energy your appliances consume by analyzing star
ratings. Improve your water heating efficiency to reduce energy
costs. At Public Places Switch of the fans and lights in the places
like bus terminal and railway stations when not necessary. Switch
off the street lights. Big Hoardings, lightened up for the whole
evening and nights are other wastage of power which can be and
should be avoided
14. ENERGY CONSERVATION IN INDIA About 70% of India's energy
generation capacity is from fossil fuels, with coal accounting for
40% of India's total energy consumption followed by crude oil and
natural gas at 24% and 6% respectively. India is largely dependent
on fossil fuel imports to meet its energy demands. By 2030, India's
dependence on energy imports is expected to exceed 53% of the
country's total energy consumption. In 2009-10, the country
imported 159.26 million tonnes of crude oil which amount to 80% of
its domestic crude oil consumption and 31% of the country's total
imports are oil imports. The growth of electricity generation in
India has been hindered by domestic coal shortages[ and as a
consequence, India's coal imports for electricity generation
increased by 18% in 2010
