RENEWABLE ENERGY
Prepared by Mathankumar.S Assistant Professor, Department of EEE, V.M.K.V.E.C, Salem
Indiscriminate exploitation of conventional energy resources.
Damage the essential elements of all living beings.
(Ozone depletion and global warming, etc., )
Find out an alternate viable source of energy eliminating the hazard’s.
Conventional Energy
Routed in harnessing the renewable energy resources for sustaining the green environment.
Never be exhausted.
less emission naturally.
Predominant sources are sun, wind, water, agricultural residues, firewood and bio waste, etc.,
Non Conventional Energy
A race is going on throughout the world in harnessing the renewable energy resources.
Technologically advanced countries have made rapid strides in this area.
Efforts to increasing energy requirements in our country.

Solar energy is the most readily available source of energy.
Non-polluting
Lessening the greenhouse effect.
Solar Energy
IREDA & MNCES are formulating a programme to have solar energy in more than a million households in the next few years.
Importance extended by the government in boosting the generation of solar and wind energy.
People’s initiative is essential.
Most suitable for harnessing solar energy for a number of applications.
Energy generated from carbonaceous waste of various human and natural activities.
Biomass Energy
It does not add carbon dioxide to the atmosphere.
Generate electricity with the same equipment.
Biomass is an important fuel worldwide after coal, oil and natural gas.
Finland, USA and Sweden the per capita biomass energy used is higher than in India.
Biomass fuels used in India account for about 1/3 of the total fuel used.
Most important biomass fuel used in
- Over 90% of the rural households &
- Around 15% of the urban households.
A mini biogas digester has recently developed, and is being in-field tested for domestic lighting.
Indian sugar mills (Around 430 Mills) are rapidly turning to biogas, to generate electricity.
This is mainly being done to
Clean up the environment
Cut down power costs &
Earn additional revenue.
Fuel cells are electrochemical devices.
Used in space flights and electric vehicles are the best option available to dramatically reduce urban air pollution.
Fuel cells for power generation – India has a large gap between the demand for and supply of power.
Ecological and Environmental impacts.
Fuel cells
The energy in the flowing water can be used to produce electricity.
Local industries should be encouraged to use this electricity for sustainable development.
Eliminates most of the negative environmental effects
Hydel Energy
Geo (Greek for earth) Thermal (heat)
Geothermal energy is “homegrown.”
Different Geothermal Energy Sources
Hot Water Reservoirs
Natural Stem Reservoirs
Geopressured Reservoirs
Geothermal Energy
Geothermal plants do not require a lot of land, 400m2 can produce a gigawatt of energy over 30 years.
One well “blew its top” 10 years after it was built, and this threw hundreds of tons of rock, mud and steam into the atmosphere.
Emission of Low Quantities of
Greenhouse Gasses
In India, Northwestern Himalayas and the western coast are considered geothermal areas.
The Geological Survey of India has already identified more than 350 hot spring sites, which can be explored as areas to tap geothermal energy.
Wind energy is the kinetic energy associated with the movement of atmospheric air.
India ranks 5th in the world with a total wind power capacity .
present utilization is only 26 TW-h/year.
The present increasing utilization of wind energy is highly supplementing our energy requirements.
Wind Energy
Five Nations – Germany, USA, Denmark, Spain and India – account for 80% of the world’s installed wind energy capacity.
Wind energy continues to be the fastest growing renewable energy source with worldwide.
Benefit of our farming community. Improving the quality of life of our
farmers.
Wastage in power Generation & transmission
Energy losses
Grid interactive failure and
Deprived power management
Present problems
Combining the difference sources of renewable energy (hybrid energy).
Hybrid Grid interactive.
Renewable energy is the ultimate energy for sustaining human life in this planet.
