  2. RenewableEnergy

  3. Structure • Generally information • Development • Solar collector • Photovoltaic • Hydropower • Advantages and disadvantages • Potential

  4. Generally information Whatis it? - alternative to fossil fuels - rebuild themselves or are indefinitely available Why? - protect the environment - reduces the production of greenhouse gases - do something against the climate change - fossil fuels are limited other source of energy How? - solar energy, geothermal energy, wind power or hydropower

  5. Development

  6. Solar collector • Change of solar radiation to heat • 1.500.000 solar energyplants in Germany • Idea originates from a hosepipe

  7. Tube Glass Vacuum Absorber Isolation Solar radiation Glass Heat radiation Isolation Cold water Absorber Tube Warm water

  8. Solar collector Solar radiation Collector Cooling water Drinking water Cistern Cold water

  9. Differences Photovoltaic and Solar collectors

  10. Photovoltaic • 600.000 households in Germany • produces electrical energy

  11. Photovoltaic Photovoltaic cell Public network inverter

  12. Hydropower • 8000 hydropower plants in Germany • biggest plant of Germany in Thüringen • biggest plant of the world is the Three Gorges Dam in China

  13. Hydropower Water Dam Generator Turbine

  14. Advantages and disadvantages Solar energy

  15. Advantages and disadvantages Hydropower

  16. Potential • half an hour: more energy than the world need in one year • survey of 2008: 30% in 2020 50% in 2030
