Energy

  1. 1. Energy Without energy nothing happens.
  2. 2. Energy Does Work! <ul><li>Work is done when objects are moved or heated. </li></ul><ul><li>Energy is never ‘used up’ it is simply converted from one form to another. Can you think of some sources of energy? </li></ul><ul><li>Fuels and food are sources of energy. </li></ul><ul><li>Can you think of any examples when energy is converted from one form to another? </li></ul>
  3. 3. Converted Energy Fuels for generating electricity. <ul><li>There are 3 main classes of fuel which can be used to generate electricity: </li></ul><ul><li>Fossil fuels, renewable fuels and nuclear fuels. </li></ul><ul><li>What are fossil fuels? </li></ul><ul><li>What are renewable fuels? </li></ul><ul><li>How are these fuels used to generate electricity? </li></ul>
  4. 4. Energy is released from the fuel. <ul><li>Fossil fuels such as gas, coal and oil and renewable fuels such as wood, are burnt and heat is generated. </li></ul><ul><li>This heat is used to boil water and the steam that is created is used to turn large propellers called turbines. </li></ul><ul><li>These turbines then turn electrical generators. </li></ul>
  5. 5. ENERGY <ul><li>In addition to these fuels there are other energy sources used to generate electricity. </li></ul><ul><li>Can you think of any? </li></ul>
  6. 6. Other Energy Sources <ul><li>Solar power: converts the energy of the sun into electricity. </li></ul><ul><li>Wind power: Moving air can be used to turn propellers. </li></ul><ul><li>Hydroelectric power: using water. The higher the drop and the greater the drop, the more energy can be created. </li></ul><ul><li>Wave power: wind causes waves to form on the water and the motion of these waves can be used to turn generators. </li></ul>
  7. 7. What have we learned? <ul><li>Energy does work. </li></ul><ul><li>Energy is never ‘used up’ it is simply converted from one form to another. </li></ul><ul><li>Fuels and food are sources of energy. </li></ul><ul><li>There are 3 main classes of fuel which can be used to generate electricity: Fossil fuels, renewable fuels and nuclear fuels. </li></ul><ul><li>Fossil fuels such as gas, coal and oil and renewable fuels such as wood are burned and heat is generated. </li></ul><ul><li>This heat is used to boil water and the steam that is created is used to turn large propellers called turbines. </li></ul><ul><li>These turbines then turn electrical generators. </li></ul><ul><li>There are other sources of energy such as: Solar power, wind power, hydroelectric power and wave power. </li></ul>
  8. 8. These photographs show ways of getting energy from four different energy sources. Can you name them?
