Energy Conservation Tips
1Lesson 1 Introductory Lecture
Lesson Objectives
Lesson 1 Introductory Lecture 2
Operate the ceiling fan in conjunction with your window air conditionero Spreads the cooled air more effectively throughout the
roomDon't place lamps or TV sets near the air-
conditioning thermostato The thermostat senses heat, and the air conditioner to
run longer than necessaryChoose an energy-efficient appliance by checking the
energy labels
Air Conditioners
Lesson 1 Introductory Lecture 3
Leave enough space between your refrigerator and the wallso Facilitates better air circulation around the refrigerator
Cover liquids and wrap foodso Uncovered foods release moisture and make the
compressor work harderAvoid putting hot or warm food straight into the
fridge
Refrigerators
Lesson 1 Introductory Lecture 4
Always wash only with full loadso Prevents an unnecessary waste of water and electricity.
Dry clothes naturally rather than use electric dryersFabric conditioner reduces creases which means less
ironing timeo Saves electricity that would normally be used to iron the
clothing
Washing Machines
Lesson 1 Introductory Lecture 5
Set computers, monitors, and copiers to use sleep-mode when not in use o Cuts energy costs by approximately 40%.
Pull the plug and saveo 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 useo Reduces system wearo Saves energy
Computers
Lesson 1 Introductory Lecture 6
Cover pots while cooking cooks faster.Match the size of the pot with the size of the burner
o Energy is lost when the heating element is larger than potUse Pressure cookers
o Consumes less energy, cut by 50% - 70%o Saves up to two-thirds in cooking time
Cooking
Lesson 1 Introductory Lecture 7
Do not bake large food itemso 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 conditiono Each opening leads to a temperature drop of 25C
Microwaves
Lesson 1 Introductory Lecture 8
Focus light only on wherever that’s necessary, instead of brightly lighting an entire roomo 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 9
Switch on instantaneous water heater before shower and turn it off in the middle of your batho Remaining amounts of water would have been warmed up
alreadyAlways remember to turn off the water heater
o Constantly keeping the water in th water tank at high temperatures consumes large amounts of energy
Water Heater
Lesson 1 Introductory Lecture 10
Do not switch on the power when TV and Audio Systems are not in useo Idle operation leads to an energy loss of 10 watts/device
TV and Audio Systems
