Renewable sources of energy

RENEWABLE
SOURCES OF ENERGY
Ajay Kumar Jakhar

Renewable energy is energy that comes from
resources which are continually replenished such as
sunlight, wind, rain, tides, waves and geothermal heat.
Ajay Kumar Jakhar

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 the
earth from the sun. This energy is in the
form of solar radiation.
Ajay Kumar Jakhar

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.
Ajay Kumar Jakhar

Uses of wind power
Ajay Kumar Jakhar

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.
Ajay Kumar Jakhar

Uses of Biomass
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 and
stored in the Earth. Thermal energy is the energy that
determines the temperature of matter. The
Geothermal energy of the Earth's crust originates from
the original formation of the planet (20%) and from
radioactive decay of minerals (80%).
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 from
the energy of falling water and running water, which
may be harnessed for useful purposes. Since ancient
times, hydropower has been used for irrigation and
the operation of various mechanical devices, such as
watermills, 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

Tidal energy, is a form of hydropower that converts
the energy of tides into useful forms of power - mainly
electricity.
Ajay Kumar Jakhar

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 .
