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
21. Solar water heater: flat plate

Example:
Face area: 2 sq.
Meter
Temperature
range :50-70 deg.C
Cost:@Rs.180/LPD

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

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.
