What is Non-Conventional Energy?
The non-conventional energy is also called as renewable
energy. The non-conventional sources of energy include solar power, bio-mass energy, wind energy, fuel-cells, electric vehicles, tidal energy, hydrogen
energy and geo-thermal energy.
These sources of energy are discussed below:

1. 1. Solar Energy:-
Solar energy is one of the most important
sources of non-conventional energy. Solar energy is non-exhaustible, reliable
and pollution free. It may be utilized for water heaters, power generation
devices, air-conditioning, space heating, development of pisci-culture, and
multifarious uses of water and refrigeration.
The average amount of solar energy received
in the earth’s atmosphere is about 1353 KW per sq. metre. It is 1000 times the
total consumption of the global energy. Being situated in the sub-tropical
latitudes, India receives higher amount of solar energy. The greater part of
the country has more than 300 solar days. The amount of energy received from
the Sun is about 5000 trillion kWh per year.
In many parts of the country, the solar
energy programmes have been implemented. One such example is the Rural Energy
Co-operative at Sagar Island in the Sundarban Delta of West Bengal. Similar
programmes have been implemented in the other island in the Bay of Bengal, the
desert of Jodhpur (Rajasthan), Kalyanpur (Aligarh) and Coimbatore.
2. 2. Wind Energy:-
Wind is important source of
non-conventional energy. It is cheap, pollution free, eco-friendly and can be
developed away from the sources of fossil fuels (conventional sources of
energy). Since ancient times wind energy was utilized in sailing ships and wind
mills. For the generation of wind energy, a wind speed of more than five km per
hour is considered to be suitable. Wind speeds above 10 km per hour are
prevalent over parts of the coastal regions of Gujarat, Andhra Pradesh,
Karnataka, Madhya Pradesh, Rajasthan, Tamil Nadu, Maharashtra, Kerala, Odisha,
West Bengal, Uttarakhand, Jammu and Kashmir and Andaman and Nicobar Islands.
The state of Rajasthan and Ladakh also record suitable consistency of wind
speed. Wind mills can be operated there to harness wind energy.
3. 3. Ocean Energy:-
The tidal waves and sea-waves are the main
sources of ocean energy. India has a very long coastline, more than 6100 km,
but the ocean energy production is limited. The suitable areas for the
generation of tidal and sea-waves energy are:
a)
The Gulf of Khambat
b)
The Gulf of Kachchh
c)
The Estuary of Hooghly
The main problem in the exploitation
of ocean energy is the high cost involved in the construction of civil works.
4. 4. Geothermal Energy:-
India has very limited potential of
geothermal energy. According to one estimate, the total geothermal energy is
about 600 MW. There are 115 hot water springs in the country and 350 sites from
which geothermal energy can be produced. The Puga Valley in Jammu and Kashmir,
the Manikaran area in Himachal Pradesh, western slopes of the Western Ghats in
Maharashtra and Gujarat, the Narmada-Son Valley and the Damodar Valley are the
main areas which have potential for the generation of thermal energy.
5. 5. Bio-Energy:-
Bio-energy is clean source of energy which
improves sanitation, hygiene and the living style of the rural population. The
technique is based on the decomposition of organic matter in the absence of air
to produce gas. Bio-gas is used for cooking, and lighting fuel in specially
designed stove and lamps respectively.
