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

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.
