2. objectives study the uses of solar energy.
find more uses of solar energy.
let people know about the advantages of solar energy.
develop the department of the solar energy
to find solution to problems of solar energy.

3. Literature review
Florida Energy Extension Service (1992) in this article they discuss the practical uses of solar energy. They have talked about new way of heating the pools and water by the solar energy. Also, powering the electricity uses in the houses by solar energy. They have talked about the benefits and costs of replacing to solar energy.
Stitching TOOL, Amsterdam (1990) this article has talked about the electricity coming from the sun, and warming water with solar energy. Also, the author talked about different uses and applications of solar energy.

4. Solar energy
Solar energy is found by collecting sunlight and converting it into electricity. They done it by using solar panels.
1,350 W/m2 is the solar energy coming to Earth
the amount of energy that reach the earth is different depend on (weather cloudy or sunny- air pollution- Seasons of the year.

5. Why solar energy? What is the special about it? limitless supply
a free energy but not their equipments
more than enough (energy coming to our world every day 10, 000 times more than yearly requirement)
Pollution Free
flexibility (solar equipment can be made in many degrees of perfection and in a wide range of sizes and costs)

6. Uses of solar energy: Solar water heating:
we can make every electrical device running by using solar panels
Examples (cars- space programs)
Solar water heating:
1. The Efficiency of the device can be improved by spectrally selective surfaces .
2. The sunlight heats the water which is in the tank. Then, a pipe that faucet the hot water to house
3. can be use for bathing, dishwashing, and clothes washing

7. Leaders of solar energy:
When it was expansive to buy the coal, people have found a new thing to extract energy. So, they moved to the oil and gas.
nowadays the demands and prices have increases of fossil fuels. So, people are moving to other energy recourse.

8. Solar energy in Saudi Arabia:
Saudi Arabia reaches between 1900 to 2500 W/m2
Saudi Arabia is a wealthy country because of the oil producing
it seems that the world will leave the fossil fuels.
if we did not move on to solar energy while we have the money, we will end up as before the oil producing

9. Conclusion 1,350 W/m2 is the solar energy coming to Earth
a free energy- more than enough-Pollution Free –flexibility
There are many uses of solar such as (cars- space programs- Solar water heating)
