sustainable energy

  1. 1. Tammy & Thierry Present...
  2. 2. Outline <ul><li>What are we (and you) going to do </li></ul><ul><ul><li>Introduction about energy </li></ul></ul><ul><ul><li>What are the problems we are facing? </li></ul></ul><ul><ul><li>What is sustainable energy? </li></ul></ul><ul><li>What will you learn? </li></ul><ul><ul><li>Gain basic knowledge about different energy sources </li></ul></ul><ul><ul><li>Understanding opportunities for sustainable energy research </li></ul></ul><ul><ul><li>Discussing different options for the future </li></ul></ul>
  3. 3. What is energy? <ul><li>Energy is everywhere and is needed to do any work, make any sound, work, movements, light..... </li></ul><ul><li>Energy can be stored chemically (fuel, wood, food) </li></ul><ul><li>Energy cannot be lost but it can be converted into another form </li></ul><ul><li>We can make use of that for our industries or daily lives </li></ul>Dutch Windmill Woodfire
  4. 4. Energy <ul><li>Energy is usually produced by the sun </li></ul>
  5. 5. Energy <ul><li>Power of sun can be used directly by us </li></ul><ul><li>But most of the time it is first stored by plants </li></ul><ul><li>This energy can be used by your body, when we eat plants...... </li></ul>
  6. 6. Energy <ul><li>Stored energy can be used later when we burn fuel derived from plants </li></ul>
  7. 7. Energy <ul><li>‘ Mother earth’ already stored lots of plants for us </li></ul><ul><li>They have been converted to so-called ‘fossil fuels’ </li></ul><ul><li>Advantages: easy to carry, highly concentrated </li></ul><ul><li>With new technologies, more fossil fuels become accessible </li></ul>
  8. 8. Easy access made us dependent <ul><li>Our economy became highly dependent upon fossil fuels </li></ul>
  9. 9. Problems with fossil fuels <ul><li>Problem with fossil fuels: supply is limited </li></ul><ul><li>We started using fossil fuels about 150 years ago </li></ul><ul><li>In the current pace, we will be out of business within the next century(!) </li></ul><ul><li>It takes hundreds of millions of years to regenerate this supply </li></ul>
  10. 10. Fossil fuels and Global Warming <ul><li>More problems: burning fossil fuels causes CO 2 levels to rise </li></ul><ul><ul><li>This causes greenhouse effect, thus global warming </li></ul></ul><ul><li>Another reason to look for alternatives very fast! </li></ul>
  11. 11. Sustainable energy <ul><li>“ Sustainable energy is the provision of energy such that it meets the needs of the present without compromising the ability of future generations to meet their needs” </li></ul><ul><li>So: use energy sources that are directly at hand in order to stop our dependency on fossil fuels </li></ul><ul><li>Use these at a rate so that the earth can sustain our consumption </li></ul>
  12. 12. Group Assignment 1 <ul><li>Please mention at least three types of fossil fuels </li></ul><ul><li>Try to mention as many sources of sustainable energy as possible </li></ul><ul><li>We will discuss this in 10 minutes </li></ul><ul><li>Good Luck! </li></ul>
  13. 13. Answer to assignment 1 <ul><li>Fossil fuels are oil, coal and gas </li></ul><ul><li>Sources of Sustainable Energy </li></ul><ul><li>There are 5 main sources of sustainable energy: </li></ul><ul><ul><li>Water (Watermills, but also [tidal] waves) </li></ul></ul><ul><ul><li>Wind (Windmills, windturbines) </li></ul></ul><ul><ul><li>Sun (heating water or solar panels) </li></ul></ul><ul><ul><li>Biomass (fuels eventually derived from plants) </li></ul></ul><ul><ul><li>Earth (earth produces heat within, e.g. geisers, volcanoes, but we can also build power plants that make use of this) </li></ul></ul><ul><ul><li>[Nuclear power is sometimes considered as sustainable] </li></ul></ul><ul><ul><ul><li>However: opinions divide about this </li></ul></ul></ul>
  14. 14. Improving sustainable energy sources <ul><li>We used those sources for hundreds of years </li></ul><ul><li>However, our energy consumption has increased dramatically (!) </li></ul><ul><li>New technologies enable us to improve efficiency </li></ul><ul><li>Time is running out! We should act fast! </li></ul>
  15. 15. Sustainable energy: which one to choose? <ul><li>Many sources of sustainable energy </li></ul><ul><li>Choice can depend on </li></ul><ul><ul><li>Application </li></ul></ul><ul><ul><ul><li>Fuel for moving vehicles </li></ul></ul></ul><ul><ul><li>Climate and circumstances in the country </li></ul></ul><ul><ul><ul><li>Sun </li></ul></ul></ul><ul><ul><ul><li>Wind </li></ul></ul></ul><ul><ul><ul><li>Water </li></ul></ul></ul>
  16. 16. Group assignment 2 <ul><li>Each group gets a country factsheet </li></ul><ul><li>Discuss in your group (and decide) which source of sustainable energy you are going to develop for electricity production within the next decade </li></ul><ul><li>You must be able to explain why you chose this source! </li></ul>
  17. 17. Disadvantages of sustainable energy: applications <ul><li>Much energy is used as liquid fuel </li></ul><ul><li>Not every type of sustainable energy can be put into liquid form </li></ul><ul><li>Solutions </li></ul><ul><ul><li>Make electric-powered cars </li></ul></ul><ul><ul><ul><li>-heavy batteries needed! </li></ul></ul></ul><ul><ul><li>Store energy as liquid hydrogen </li></ul></ul><ul><ul><ul><li>-dangerous! </li></ul></ul></ul><ul><ul><li>Use biomass in liquid form (bio-ehtanol or palm oil) </li></ul></ul><ul><ul><ul><li>-hugh land areas needed in order to produce enough for our demand! </li></ul></ul></ul>
  18. 18. Disadvantages of sustainable energy: reliability <ul><li>Many types of renewable energy are dependent on natural resources that are unpredictable </li></ul><ul><li>For instance: </li></ul><ul><ul><li>Wind </li></ul></ul><ul><ul><li>Sun </li></ul></ul><ul><ul><li>Waves </li></ul></ul><ul><ul><li>Water </li></ul></ul>
  19. 19. Group assignment 3 <ul><li>Every group is assigned to one type of sustainable energy </li></ul><ul><li>Think of any undesired (negative) effect your type of sustainable energy can cause. </li></ul><ul><li>Do you still think there is enough reason to regard your type of energy as ‘sustainable’? </li></ul>
