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