SOLAR ENERGY

Every day, the sun radiates an large amount of

energy- called solar energy.

It radiates more energy in one second than the

world has used since time began.

o Solar energy can be used as a source ofheat and light and can be used to generate

electricity.

MAINSTREAM FORMS OF RENEWABLE

ENERGY

Hydropower 34%

Solar energy 5% Biomass

Biofuel 2%

Geothermal energy 52% Wind Power 4%

SOLAR WATER HEATER

Solar energy can be used to heat water. Heating

water for bathing, washing, dishwashing and forcloth washing.

This is all through solar collector


5/18

SOLAR ENERGY AS ELECTRICITY

Energy from the sun can be used to make

electricity directly with photovoltaic panels or

indirectly using concentrated sunlight to heat aliquid, which produces steam to turn electrical

turbines. Concentrating solar plants can be built

to store heat and deliver power for several hours

without sunlight.

PARABOLIC DISHES AND TROUGHS

Because they work best under direct sunlight,

parabolic dishes and troughs must be steered

throughout the day in the direction of the sun.

Collectors in southern CA.

LIFE AND COST

Average 20-30 years

Efficiency of solar cells is 30 % and it decreases 1% peryear.

Research on manufacturing and output efficiency andrecycling ongoing.

The cost of solar installations has fallen in recent years,but remains high, partly because demand continues to keeppace with supply. Normally 95 Rs/watt excluding dcbatteries and inverter.

WIND POWER


12/18

SPEED OF WIND MILL

The amount of energy which the wind transfers

to the rotor depends on the density of the air, the

rotor area, and the wind speed.

Wind is slowed by the surface roughness and

obstacles


13/18

DESIGN OF WIND MILL

A Windmill captureswind energy and thenuses a generator toconvert it to electricalenergy.

The design of a windmillis an integral part of howefficient it will be.

When designing a

windmill, one mustdecide on the size of theturbine, and the size ofthe generator.

CONCLUSION

The fossil fuels are depleting at much faster rate

and if it goes on like this youll be left with

nothing so we should be looking forward to shift

towards the renewable sources of energies which

could stay on the earth as long earth lives.

we need to be eco friendly. Thus preventing

green house effect and encouraging greenary all

around the world.
