SUSTAINABILITY - ENERGY: RENEWABLE AND NON-RENEWABLE

  1. 1. SUSTAINABILITY 02 ENERGY RENEWABLE AND NON-RENEWABLE
  2. 2. ENERGY EXPLAINED VIDEO https://www.youtube.com/watch?v=Yh34BYMVTxs
  3. 3. Energy = the amount of force or power when applied can move one object from one position to another. Energy exists in everybody - Human beings - Animals - Non living things (machines) WHAT IS ENERGY?
  4. 4. FORMS OF ENERGY VIDEO https://www.youtube.com/watch?v=FX7T-QYTPho
  5. 5. • Kinetic (energy that an object possesses due to its motion) • Potential (energy possessed by a body by virtue of its position relative to others) • Light (formed through chemical, radiation, mechanical means) • Sound (produced when an object vibrates) • Gravitational (energy an object possesses because of its position in a gravitational field) • Elastic (potential mechanical energy stored in the configuration of a material, distort of volume or shape) • Electromagnetic (term used to describe all the different kinds of energies released into space by stars such as the Sun) • Nuclear (energy released during nuclear fission or fusion, especially when used to generate electricity). FORMS OF ENERGY
  6. 6. HOW DO ENERGY CONVERT VIDEO https://www.youtube.com/watch?v=ftj23FRS2LI
  7. 7. Any form of energy can be converted into another form and the total energy will remain the same. When you charge your mobile phone, the electrical energy is converted into the chemical energy which gets stored inside the battery’s molecules. ENERGY CONVERSION
  8. 8. FOSSIL FUELS, THE GREENEST ENERGY VIDEO https://www.youtube.com/watch?v=BJWq1FeGpCw
  9. 9. Over the last 200 years a large proportion of our energy has come from non-renewable sources such as oil and coal. Demand for energy rises, and the resources are running out. Scientists are exploring the potential of renewable sources of energy for the future. All life on earth is sustained by energy from the sun. FOSSIL FUELS
  10. 10. Examples of non-renewable resources include: • Coal • Oil • Natural Gas • Nuclear NON-RENEWABLE ENERGY
  11. 11. Renewable or infinite energy resources are sources of power that quickly replenish themselves and can be used again and again. Examples of renewable resources include: • Solar • Wind • Hydro • Geothermal • Tidal • Wave RENEWABLE ENERGY
  12. 12. RENEWABLE ENERGY VIDEO https://www.youtube.com/watch?v=1kUE0BZtTRc
  13. 13. Some resources can be thought of as both renewable and non-renewable. • Wood (can be used for fuel and is renewable if trees are replanted). • Biomass (material from living things, can be renewable if plants are replanted). RENEWABLE AND NON-RENEWABLE ENERGY
  14. 14. BIOMASS AND WOOD ENERGY VIDEO https://www.youtube.com/watch?v=nVl17JLn_u0
  15. 15. The NZ government wants to reduce its carbon dioxide emissions. It also wants to increase the amount of energy which comes from renewable sources. By 2025 targets state that 90% of energy must come from renewable sources. There are 2 ways the energy use can change in New Zealand: • Reducing the demand for energy • Increasing the supply of renewable energy PEOPLES’ USE OF ENERGY IN NEW ZEALAND
  16. 16. The demand for energy in the NZ varies. This is because of: • Economic factors: During the recession energy demand did not increase as predicted • Seasonal factors: Demand for domestic energy over winter is greater than over the summer. • Temporal factors: At night there is surplus energy on the national grid because demand is lower REDUCING DEMAND FOR ENERGY IN NEW ZEALAND
