RENEWABLE SOURCES OF ENERGY
Ajay Kumar Jakhar
Renewable energy is energy that comes fromresources which are continually replenished such assunlight, wind, rain, tides, waves and geothermal heat.

In contrast to fossil energies such as oil, coal, uranium and natural gas, the use of renewable energies protects the climate and environment, is resource-efficient and safe.
Renewable energies ensure greater independence from energy imports, greater security of supply and strengthen the domestic economy.
Using renewable energies avoids climate-damaging emissions which cause significant follow-up costs and have serious impacts.
Ajay Kumar Jakhar
Solar energy is the energy received by theearth from the sun. This energy is in theform of solar radiation.

The electricity generated by solar panels is free of cost.
Government offers lots of rebates and incentives to cover the initial cost.
The cost of technology is decreasing almost every few months and the efficiency is improving significantly.
Solar energy is a renewable and clean source of energy.
Ajay Kumar Jakhar
The initial cost of installation and equipment is high.
Our inability to control or predict how much solar energy arrives on the earth’s surface at any place.
A large surface is required for collecion of useful amounts of
solar energy.
Ajay Kumar Jakhar
Wind power is the conversion of wind energy into a useful form of energy, such as using wind turbines to
make electrical power, windmills for mechanical power, wind pumps for water pumping or drainage, or
sails to propel ships.

Wind energy is also a source of clean, non-polluting, electricity.
Wind plants emit no air pollutants or greenhouse gases.
The energy of generate is renewable.
Ajay Kumar Jakhar
The technology requires a higher investment than fossil-fueled generators.
Wind turbines make noise.
Birds and bats have been killed by flying into the rotors.
the major challenge to using wind as a source of power is that it is intermittent and doesn’t always blow when electricity is needed.
Ajay Kumar Jakhar
Biomass is biological material from living, or recently living organisms, most often referring to plants or
plant-derived materials. As a renewable energy source, biomass can either be used directly, or
indirectly—once or converted into another type of energy product such as biofuel. Biomass can be
converted to energy in three ways: thermal conversion, chemical conversion, and biochemical
conversion.

Uses of Biomass
Ajay Kumar Jakhar
Ajay Kumar Jakhar
Available almost everywhere.
Sulfur, nitrogen oxides, and carbon emissions can be significantly reduced by burning biomass.
Growing biomass crops produce oxygen and use up carbon dioxide.
Ajay Kumar Jakhar
More expensive than convention fossil fuels.
A less concentrated form of energy, making it less efficient.
Releases some emissions, especially if burned improperly.
Research is needed to reduce the costs of Biomass based fuels.
Ajay Kumar Jakhar
Geothermal energy is thermal energy generated andstored in the Earth. Thermal energy is the energy thatdetermines the temperature of matter. TheGeothermal energy of the Earth's crust originates fromthe original formation of the planet (20%) and fromradioactive decay of minerals (80%).

Uses of geothermal energy
Ajay Kumar Jakhar
Uses of geothermal energy
Ajay Kumar Jakhar
Geothermal energy involves low running costs.
It does not create any pollution.
It creates job for the local people.
Ajay Kumar Jakhar
Requires huge one time investment.
Suitable only for regions with hot rocks below the earth.
Sites may contain poisonous gases which may pollute the environment.
It cannot be easily transported.
Ajay Kumar Jakhar
Hydropower or water power is power derived fromthe energy of falling water and running water, whichmay be harnessed for useful purposes. Since ancienttimes, hydropower has been used for irrigation andthe operation of various mechanical devices, such aswatermills, sawmills, textile mills, dock cranes,domestic lifts, power houses and paint making.
Ajay Kumar Jakhar
Uses of Hydro power
Ajay Kumar Jakhar
No fuel used so no pollution.
Relatively low operations and maintenance costs.
The technology is reliable and proven over the time.
Ajay Kumar Jakhar
Requires huge one time investment.
Suitable only for regions with hot rocks below the earth.
Sites may contain poisonous gases which may pollute the environment.
It cannot be easily transported.
Ajay Kumar Jakhar
Tidal energy, is a form of hydropower that convertsthe energy of tides into useful forms of power - mainlyelectricity.

Tidal and wave energy is free, renewable, and clean source of energy .
Highly efficient resource (compared with coal and oil at 30%, tidal power efficiency is about 80%).
Energy capturing and conversion mechanism may help protect the shoreline.
Ajay Kumar Jakhar
It only produces electricity during tidal surges.
Technology isn't fully developed
Appropriate waves and tides are highly location dependent
Ecosystem is disrupted during the construction of building the tidal fence. this affects the fishes and also the fishermen who depends their life on it.Ajay Kumar Jakhar
The renewable energy supports the government's objectives of 'inclusive growth' and is part of solutions to meet nation's energy needs.
The sector has grown at an annual rate of 23% to about 25,000 MW in March 2012 .
The renewable power installed capacity forms 6.5% in the total electricity mix and 12.5% of total installed capacity in 2011- 2012 .
With 17,352 MW of generation, WIND continues to account for 70% of installed capacity .
