2. Renewable sources of energy cannot play a key role in
india’s power sector in the next tevn years ,without
consumers and the economy paying very high
opportunity cost
• Attraction towards renewable energy
• Growth and emergence of renewable energy in india
• Technology hurdles in renewable energy
• Role of subsidies and other incentives offered by indian
government

3. Why renewable energy became so attractive
in the 1970
• Fear of disappearing of fossil fuel from world
• Dependency of India on OPEC(Organization of Oil
Exporting Countries)
• Pollution and environmentally damaging
emissions from fossil fuel based plants generating electric
power
• Emergence of renewable energy as the cleanest and
cheapest technology

4. Coal and oil reserves in India
Fuel Proven Indicated Years to last
reserves reserves
Oil 5.7 bbarrels 30 btonnes 50
Coal 82 bbarrels 211 btonnes 300
Recent international studies indiacate that no more than a
quarter of india’s 26 secondary basins have a serious
exploration activity.these includes oofshore basins covring
about 3,80,000 sq km and on shore basins covering 13,40,000
sq km.it contains 30 billion tonnes of reserves 5 times the
current figure.

5. •Inflation rates after the two oil shocks of 1973 and 1979 were
13 and 19 per in india .hence self reliance and import
substition were development mantras used by our govt in he
five year plans.
•But dependency on OPEC reduced by policy makers
encouraging intensive exploration activities in untapped areas
by attracting private capital

6. Gas Reduction in emission
Sulphur dioxide 99%
Nitrogen oxide 81%
Carbon dioxide 58%
particulates 95%
•Electricity generation increased by 14pc between 1989 and
1996 by reducing emission gases by 20 pc with the help of
high tech pollution control technology.this will increase the cost
of electricity by only 1pc. These will leave renewable sources
which is at least 50 pc more expensive than fossil fu

7. India as a renewable energy super power
• India is the leading country in the asia and in the world for
generating electric energy by renewable energy
• India is the fifth largest wind energy producer in the
world
• The ministry of non-conventional energy sources is the
only one of its kind in the world
• Only a fraction of the total potential of renewable energy
sources has been utilized in india.

9. Renewable energy capacities : potential and installed (till april 2000 in
MW)
source Potential installed
Wind 45,000.00 1167.00
Solar 50,000.00 57.00
Bio-mass 21,000.00 255.00
Small-hydro 10,000.00 217.00

10. Renewable energy technology
• Renewable energy technology are primitive
• Renewable energy technology is inefficient and
uneconomical
• Renewable energy is not reliable
• Renewable energy is dependent
11/20/03 200231019
11. • It prevents from supplying either base load or peak load levels of
consumer demand .even intermediate level is a big challenge
• 2,100mw coal fired plant of NTPC at korba in Chattisgard
generates more electricity than all the capacities installed under
renewable energy
• For every kilowatt of installed capacity,conventional power plants
produce 4,000 to 7,000kwh of electricity. Wind plant manage 2000 to
2,500kwh and solar PV plants generate 750-1500kwh
• More than 85pc of renewable enegy caopacity is for captive
consumption
• Low capacities ,lower utilization rates and irregular supplies play
havoc with electricity grid
• The largest contributor to electricity supply in india ,wind energy
with installed capacity of 1100mw produces 1650 gigawatt hour of
electricity with a capacity utilization of 15pc which is less then a
single11/20/03 plant of 250mw

14. • Renewable energy is fully dependent on subsidies
• Eight crore rupees is given as capital subsidy in the co-
generation plant with maximum capacity of 20mw
• Various studies estimate that US taxpayers have spent 25 to
40 pc billion us dollars to enable renewable source of energy to
get a one and half pc market share
• India had spent more than 3000 crore during 1990s
promoting wind energy.
• IREDA has sanctioned 4600 crore till end 1999 as a
loan.preventing the use of almost 1 million tonnes of coal (india
consumes close to 400 million tonnes of coal per year
• It provides electricity at much rate
• The capital cost of renewable energy plant is very high
11/20/03 200231019
15. Conclusion
• Role of indain policy in making the renewable energy efficient and
cheapest fuel as a substitute for the fossil fuels used in production of
electric energy.
• The indian government blindly spent the huge amount of money for
making the renwable energy popular without considering the
statistics
• Bowing down to the wishes of green activities and placing obstacles
in the growth path of conventional electric power supply would
directly contradict the poverty reduction goals of policy-makers
• Government should improve the existing power supply encouraging
use of hi-tech technology.
