Solar energy

  1. 1. SOLAR ENERGY Pau Boixeda BertaRifà Ferran Jutglar Vanesa Badji
  2. 2. DEFINITION OF ENERGY• Energy is the power that make things work.• We need energy to play football, to walk, or to cook our food. There are many different forms of energy , like : nuclear, kinetic, elastic, thermal, light, chemical, gravitational, ele ctrical and sound energy.• Energy can be classified as renewable and non- renewable.
  3. 3. DIFFERENCE BETWEEN RENEWABLE ENERGY ANDNON-RENEWABLE ENERGY:• Renewable energies are the energies that never run out, they dont pollute our planet and some of them produce a lot of energy. Examples: wndi energy, solar energy... And non-renewable energies, are the energies that in a day they run out, and they pollute a lot our planet.
  4. 4. WHY WE NEED TO USE RENEWABLE ENERGY?• Many forms of energy that we have grown dependent on are from non-renewable energy sources. This means that when the energy has been consumed, the supply has gone and cannot be replaced. An example of this is coal. Coal is known as a fossil fuel and is the largest source of energy for the generation of electricity worldwide. When coal has been mined and burnt, it cannot be replaced. Finding alternative energy sources, ideally from renewable sources, will decrease our dependency on fossil fuels and other non-renewable energy sources.
  5. 5. WHAT IS SOLAR ENERGY? Solar energy is the energy obtained from the use of electromagnetic radiation from the sun. Solar energy is vital to support life on earth, it helps to grow our food, light our days, influence weather patterns, provide heat, and can be used to generate solar electricity. There are two types of solar energy: Solar Photovoltaics Solar Thermal
  6. 6. ORGANITZATION We distribuied the work like this: PAU: Definition of energy, why solar energy it’s good, make the gmail, a piece the solar thermal and some photos and pictures. BERTA: Definition the photovoltaics, a piece the solar thermal, video, games, some photos and pictures and gadgets. FERRAN: He help Pau and Berta with definition of energy and definition the photovoltaics. VANESA: Decored the blog.
  7. 7. AND ADVICE FOR THE NEXT GROUP WORK: We distributed the work. We help of the group.
  8. 8. THAT WE LEARNED. We learned that is solar energy We learned that is energy Have learned to work in groups Differences between renewable energies and non-renewable energies
  9. 9. THE END
