Lesson 3 Introductory Lecture

  1. 1. Darrel Long Ong Xin Jie Teo Zheng Jie Team G-Power Energy Conservation Tips Lesson 1 Introductory Lecture
  2. 2. Lesson Objectives Lesson 1 Introductory Lecture
  3. 3. <ul><li>Operate the ceiling fan in conjunction with your window air conditioner </li></ul><ul><ul><li>Spreads the cooled air more effectively throughout the room </li></ul></ul><ul><li>Don't place lamps or TV sets near the air-conditioning thermostat </li></ul><ul><ul><li>The thermostat senses heat, and the air conditioner to run longer than necessary </li></ul></ul><ul><li>Choose an energy-efficient appliance by checking the energy labels </li></ul>Air Conditioners Lesson 1 Introductory Lecture
  4. 4. <ul><li>Leave enough space between your refrigerator and the walls </li></ul><ul><ul><li>Facilitates better air circulation around the refrigerator </li></ul></ul><ul><li>Cover liquids and wrap foods </li></ul><ul><ul><li>Uncovered foods release moisture and make the compressor work harder </li></ul></ul><ul><li>Avoid putting hot or warm food straight into the fridge </li></ul>Refrigerators Lesson 1 Introductory Lecture
  5. 5. <ul><li>Always wash only with full loads </li></ul><ul><ul><li>Prevents an unnecessary waste of water and electricity. </li></ul></ul><ul><li>Dry clothes naturally rather than use electric dryers </li></ul><ul><li>Fabric conditioner reduces creases which means less ironing time </li></ul><ul><ul><li>Saves electricity that would normally be used to iron the clothing </li></ul></ul>Washing Machines Lesson 1 Introductory Lecture
  6. 6. <ul><li>Set computers, monitors, and copiers to use sleep-mode when not in use </li></ul><ul><ul><li>Cuts energy costs by approximately 40%. </li></ul></ul><ul><li>Pull the plug and save </li></ul><ul><ul><li>Battery chargers, such as those for laptops, cell phones and digital cameras, draw power whenever they are plugged in and are very inefficient. </li></ul></ul><ul><li>Shut down computers after use </li></ul><ul><ul><li>Reduces system wear </li></ul></ul><ul><ul><li>Saves energy </li></ul></ul>Computers Lesson 1 Introductory Lecture
  7. 7. <ul><li>Cover pots while cooking  cooks faster. </li></ul><ul><li>Match the size of the pot with the size of the burner </li></ul><ul><ul><li>Energy is lost when the heating element is larger than pot </li></ul></ul><ul><li>Use Pressure cookers </li></ul><ul><ul><li>Consumes less energy, cut by 50% - 70% </li></ul></ul><ul><ul><li>Saves up to two-thirds in cooking time </li></ul></ul>Cooking Lesson 1 Introductory Lecture
  8. 8. <ul><li>Do not bake large food items </li></ul><ul><ul><li>Try to separate them such that heat can more easily “penetrate” the food items  heats up faster  less energy required to heat up the food. </li></ul></ul><ul><li>Don't open the oven door too often to check food condition </li></ul><ul><ul><li>Each opening leads to a temperature drop of 25  C </li></ul></ul>Microwaves Lesson 1 Introductory Lecture
  9. 9. <ul><li>Focus light only on wherever that’s necessary, instead of brightly lighting an entire room </li></ul><ul><ul><li>Saves energy with less lights required </li></ul></ul><ul><li>Use compact fluorescent bulbs are four times more energy efficient than incandescent bulbs and provide the same lighting. </li></ul>Lighting Lesson 1 Introductory Lecture
  10. 10. <ul><li>Switch on instantaneous water heater before shower and turn it off in the middle of your bath </li></ul><ul><ul><li>Remaining amounts of water would have been warmed up already </li></ul></ul><ul><li>Always remember to turn off the water heater </li></ul><ul><ul><li>Constantly keeping the water in th water tank at high temperatures consumes large amounts of energy </li></ul></ul>Water Heater Lesson 1 Introductory Lecture
  11. 11. <ul><li>Do not switch on the power when TV and Audio Systems are not in use </li></ul><ul><ul><li>Idle operation leads to an energy loss of 10 watts/device </li></ul></ul>TV and Audio Systems Lesson 1 Introductory Lecture
  12. 12. The End <ul><li>Any questions? </li></ul>Lesson 1 Introductory Lecture
