This is what we are going to see in future...!? Especially in “INDIA”

Scarcity of Resources..
Leads to the increase in the cost of many resources....
Which Results in the doubt of loss of existence of the NON-Renewable Resources in FUTURE...!?

Present Situation of Energy ResourcesAt Present We are in 2015..
The Statistics shows us the Energy Resources have started Decreasing Day by Day....
If we Doesn’t take a step now!
The Energy resources will definitely loss there existence in the world..

To Save the Energy ResourcesThere are some Precautions which we need to
take:
Decreasing the usage of Fuels as much as possible
Implementing the different methods of consuming less Energy
Usage of Renewable sources instead of Non-renewable source of Energy

Solar Energy….and its many uses
![Page 12: solving energy crisis through solar energy](https://reader031.fdocuments.us/reader031/viewer/2022030305/587525a11a28ab3f098b5183/html5/thumbnails/12.jpg)
SOLAR ENERGYA FEW FACTS
Every day the earth receives thousands of times more energy from the sun than is consumed in all other resources.
If a 140x140 mile parcel of land in Andhra Pradesh was covered with solar cells, the electricity needs of the entire United States could be met.
The sunlight falling on a typical house can provide from 1/3 to 1/2 of the heating needs of that house.
Today solar energy accounts for only 1% of the total renewable energy consumed in the United States

SOLAR HEATING TODAYUsed mostly for
heating pools and domestic hot water (DHW)
Two types of solar heating systems:Active Solar Heating
SystemPassive Solar

Solar Power Plant
This is the Solar power plant which is present in Gujarat(INDIA)

Solar Power plant in Rajasthan(INDIA)
![Page 19: solving energy crisis through solar energy](https://reader031.fdocuments.us/reader031/viewer/2022030305/587525a11a28ab3f098b5183/html5/thumbnails/19.jpg)
Key points:On an average each solar cell produces an
emf about 0.9 to 1.5v..!So that in a Solar Power Plant...! The solar
panels are connected in series so that the all the emf’s add up and gives us the sufficient amount of Voltage..!
Those Solar panels are connected to a GRIDThis is how ELECTRICITY is produced
through solar energy...1

Advantages of Solar EnergyHighly Efficient....Rich source of EnergyCan produce electricity easily in sunny
regions(climate)No fuel is requiredRenewable source of energy

Dis-AdvantagesHigh costCan’t produce Electricity in all regionsIt requires larger areas to buildDoesn’t works in the night..!Suitable only Sunny climatic Regions
