    1. Solar Energy .and its many uses

    2. SOLAR ENERGY A FEW FACTS Every day the earth receives thousands of times more energy from the sun than is consumed in all other resources.

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

The suns energy is created from the fusion of hydrogen nuclei into helium nuclei. Components of Solar Radiation: Direct radiation Diffuse radiation Reflect radiation
