2. INTRODUCTION
 Renewable energy is energy obtained
from sources that are essentially
inexhaustible.
 Examples: wind power, solar power,
geothermal energy, tidal power and
hydroelectric power.
 The most important feature of renewable
energy is that it can be harnessed
without the release of harmful

17. Solar power on grid/of grid
 off Grid solar power
plant can obtain the
solar energy from
solar panel, and can
stored in to the battery
Banks
 On Grid tie solar
power plant can
obtain the solar
energy from solar
panel, and can tie to
the grid through its
output cable with no
battery backups.

18. Solar power generation fact
 Rate: 200/watt for smaller plant
 Space required : 10 watt per squire feet
 Solar Power Plant comes to Rs. 15 crore for each
MW
 cost of generation of solar power Rs.16/-approx.
 Indian government is planning to offer a subsidy of
55% on installation of solar power in residential
and commercial settings.

19. Solar Appliances in India
 340,000 home illumination
systems,
 55,000 solar road lights,
 1,500 of solar PV energy
producing plants,
 575,000 solar cookers,
 560,000 solar lamps,
 6,800 solar PV pumps and
solar water heaters

20. PV water pumping system

21. Solar water heater: flat plate
collector
 Example:
 Face area: 2 sq.
Meter
 Temperature
range :50-70 deg.C
 Cost:@Rs.180/LPD
(Litre per day)
 Module : 125LPD,
250LPD,300LPD

22. Solar water heater: evacuated tube
collector
 Example:
 Face area: 2 sq.
Meter
 Temperature
range :60-80
deg.C
 Cost:@Rs.200/L
PD(Litre per day)
 Module :
125LPD,
250LPD,300LPD

23. Hydro energy
 P= 9.8 Q Hη
where:
 P= power(KW)
= plant efficiencyη
Q = discharge flow
rate (meter3
/s)
H= head (meter)

24. Water flow

25. MERIT AND DEMERIT
 Power at constant
rate
 Non -polluting
 Lower operational
cost
 easy transmission
 Help in irrigation
projects.
 Cater peak load
 High investment costs
 Loss of fish species
 Cost for construction
 Due to drought may
become useless
 Dams can break in a
massive flash flood
 Damming rivers causes
changes in ecological
cycles

26. ETHANOL,ETHYL ALCOHAL
CH3CH2OH

27. USE OF ETHANOL
 AS SOLVENT
 GERMICIDE
 ALCOHLIC BEVRAGE
 ADHESIVE
 FUEL FOR AUTOMOBILE

28. BIO DIESEL

29. BIOMASS

30. HYDROGEN ENERGY

31. Biogas

32. Bio gas fact and cost
 1m3 bio gas =0.42litre of diesel
 1m3 bio gas =0.468 kg LPG
 1m3 bio gas =0.62L of kerosene
 1m3 bio gas =3.5 kg fore wood
 1m3 bio gas =1.25 KW Electricity
 10 kg of waste per day = produces around 1
CUM of biogas.
 Cost of the system is around Rs. 15000/- per
CUM of plant.

33. ACT FAST AND INITIATE
FIRST
 बड़ा सोचो
 तेजी से सोचो व
 सबसे पहले सोचो
 िवचारो पर िकसी का
 एकािधकार नही होता.
