1. Solar power is a renewable energy that uses sunligth to generate electricity.

2. Applications There are two applications: Photovoltaics, convert sunlight directly into electricity. Concentrating solar power convert sunlight indirectly into electricity.

3. Solar power has great potential, but not used enough. However, use has been doubling every two, or less years.

4. CSP Concentrating Solar Power use systems to concentrate a large area of sunlight into a small beam. The concentrated heat is then used for a conventional power plant.

5. Photovoltaics That application uses the photovoltaic effect. It’s based on the theory that some electrons when hit with light it produces electricity. The first important application of solar cells was a back-up power sourse to the Vanguard I satellite, which it’s continue transmitting for over a year after its chemical battery was exhausted. This application was duplicated in many other satellites.

6. Solar Power in Spain Spain is a country where there are many areas which have good sunlight all year. Spain's government pledged to reach 12% renewable energy use for 2010. Spain is the fourth largest manufacturer in the world of solar power.

7. In conclusion I think solar power will be in the coming years the most used energy as never end. Maria Vilà
