  • hygienically safe
  • Water, energy and nature

    1. 1. RenewableHydro , Solar and Wind Energy Energy
    2. 2. Wind Energi• Moving air• Collect with windmills or sails.• Stock electrical energy.• Not effective under 13 km/h• Very effective over 22 km/h• Must stand in areas with lots of wind• Denmark and Netherlands are well suited• Also Norway has many good locations for windmills.• Wind farms
    3. 3. Positive sides• Wind is a renewable resource.• Wind is available everywhere.• Use of wind gives no pollution
    4. 4. Negative sides• Wind energy is now quite expensive.• Wind strength varies.• Windmills can make noise for people who live close.
    5. 5. Solar Energy•Comes directly fromthe sun•Use solar energy toproduce electricity.•Could supply thehouses with electricity
    6. 6. Positive sides Negative sides• Solar energy is free • Less used for itsef. heating.• The supply of solar • Requires such lage energy will never surfaces. og away. • It is expencive.• Gives no pullotion.• Accessable everywhere.
    7. 7. Hydropower• Water in motion.• Where used to grind corn.• Produce electicity.• Largest energy source in Norway.
    8. 8. Pos itve s ides Negative s ides • Water is a renewable • expensive to build energy • difficult to find the right • No pullotion location • low electricity prices • destroys the water flows and ecosystem s in the area
    9. 9. Wave Power• Only been tested in Norway.• Through a turbin, and then into a generator.• Challenges by wave power is:4. Destroyed machines5. Skip who sails into
    10. 10. Bøkeskogen and Farriskilden King Haakon’s 7th source
    11. 11. Bøkeskogen• Bøkeskogen (Beech wood) in Larvik is the first public outdoor recreation area in Norway. The wood is full of beautiful beech trees.• Larvik is also the home to the world’s northern most natural occurrence of beech trees.
    12. 12. Farriskilden• Farris is the name of Norway’s oldest produced natural mineral water.• The water comes from Bøkeskogen and ends up in King Haakons fountain . This take 20 years
    13. 13. MoraineThe geological conditions was made already 10 000 years ago,during the Ice Age. When it rains over Bøkeskogen, the water isfiltered and absorbs minerals and trace elements as it moves inthe underground channels of King Haakon and King OlavSource. This process takes approx. 15-20 years. The only thingthe facory does is to remove the sulfur and add carbonic acid.
    14. 14. Natural mineral water Farris• On its way it ”collects” a lot of minerals, so the water is very healthy.• Farris is one of Norway’s most known tranemarks.
    15. 15. Farris• large lake of 21.3 km2•catchment area of 488 km2•22 meters above sea level•Swim•fish in the water•Source of water•hygienically safe•200,000 people•very pure water
    16. 16. Voss water The Voss Lindsey Lohanwater bottle drinking Voss water
    17. 17. Facts about Voss• Voss is a brand of bottled water from Norway.• Voss water is available in still and sparkling.• Voss is marketed in over 50 countries around the world with focus on the United States.• Voss water is very popular. All the famous stars drink it. It is also used in movies, Tv episodes, Songs and on singing contests.
    18. 18. Survey• Is the water in the watertap better than water on bottle? Yes: 76% No: 24%• Do you drink water from the tap in other countries? Yes: 9,5% No: 90,5%• Do you drink water instead of other drinks? Yes: 34% No: 66%
