RENEWABLE ENERGY & ITS
FURURE PROSPECTS IN INDIA
Energy that comes from the
sources which are continous
replenished such as sunlight ,
wind, rain, tides, waves and
About 16% of global energy comes
from renewable resources.
10% of all energy from traditional
3.4% - hydroelectricity
3% - new renewables
PROJECTION IN INDIA
Renewable energy replaces
four distinct areasElectricity generation
Hot water/space heating
Rural energy services
HISTORY OF RENEWABLE
Prior to the development of coal in the
mid 19th century nearly all energy was
By 1873, concerns of running out of coal
promoted experiments using Solar energy.
Development of Solar engines continued
untill the outbreak of World War 1st.
In the 1970’s enviromentalist promoted
the development of renewable energy for
replacement of oil and decreasing
dependence on oil leading to the first
electricity generating Wind Turbine.
HISTORY OF RENEWABLE
ENERGY IN INDIA
1970’s energy crisis led to the
establishment of the COMISSION FOR
ADDITIONAL SOURCES OF
ENERGY(CASE) in the Department of
Science and Technology in Mach 1981.
In 1982, a new department was created in
the Ministry of Energy i.e. Department of
Non-conventional Energy Sources(DNES).
A decade later in 1992, DNES became
Ministry of Non-conventional Energy
Sources(MNES) and in October 2006 it
gained its current name as Ministry of
New and Renewable Energy.
Air flow can be used to run
Wind turbines range from
600kW to 5 MW.
Turbines of 1.5-3MW are most
Areas where winds are
stronger are more constant.
Long term technical potential
of wind energy Is believed to
be total 5 times current global
Energy in water can be
harnessed and used.
Since water is 800 times
denser than air even a slow
flowing stream of water can
yield considerable amount
Micro – hydro systems
produce 100kW of energy.
Run of the river
derive kinetic from rivers
and oceans without creation
of a large reservoir.
Energy from the Sun in the
form of Solar radiations for
heat or to generate electricity.
Solar powered electricity
generation uses either
photovolatics or heat engines.
Other solar applications
include space heating and
cooling through solar
architecture, day lighting, solar
hot water, solar cooking and
high temperature process
Through the process of
capture the solar energy.
When the plants are burnt
they release this energy.
Thus biomass functions
as a natural battery for
storing solar energy.
The largest source of
biomass is Peat which is
classified as slow
renewable fuel by IPCC.
It is the energy generated
and stored in the Earth.
Thermal energy is the
energy that determines the
temperature of matter.
Earth’s geothermal energy
originates from the original
formation of planet and
from radioactive decay of
From hot springs
geothermal energy is used
for electricity generation.

The National Action Plan on Climate Change in
June 2008 identified Solar energy development.
In Nov 2009 the GoI approved National Solar
Mission which aims to enable 20,000 MW to be
dployed in India by 2022.
India occupies 5th position in the World in Wind

INDIA’s RENEWABLE ENERGY
To reduce per unit cost of renewable
Harness lower wind speeds.
Challenge the energy of tides and
waves to produce energy.
Use of larger grids with lower losses
Use of hydrogen as an energy storage
The Ministry of New and Renewable
energy has fixed a target of 10500MW
between 2007-12, but an additional
generation capacity of only about
6000MW might be available for
commercial use by 2013.
MNRE has announced a revised
estimation of the potential wind
resource in India from 49130MW at
50m Hub height to 102788MW at 80m
The National Energy Policy aims at

There is an urgent need for transition from
petrolium based energy system to one
based on renewable resources to decrease
reliance on depleting reserve e of fossil
fuels and to mitigate climate change.
It has potential to create employment
opportunities especially at all levels
especially at rural level.
An emphasis on presenting the real picture
of massive renewable energy potential, it
would be possible to attract foreign
investments to herald a Green Energy
Revolution in India.
