    Study Notes

    Energy Efficiency

    • Energy efficiency is using less energy to provide the same services without compromising comfort, safety, and quality.
    • It is not the same as energy saving, although energy efficiency can lead to energy saving.

    Identifying Energy-Wasting Situations

    • Watching TV with the lights off
    • Using air conditioning at a temperature of 16 degrees Celsius
    • Reading using a table lamp
    • Letting the light be on in the morning

    Load Apportioning

    • Television, Vacuum, Satellite Dish, and Decoder: 0.5% - 1.7%
    • Iron and Others: 0.9% - 1.1%
    • Fan: 4.4%
    • Lighting: 5.1%
    • Air Conditioner: 39.8%
    • Refrigerator: 21.4%
    • Centralized Water Heater: 23.7%

    Energy Saving Benefits

    • Economical Factor: reduces electricity bills and operating costs, increasing profits
    • Non-Economical Factor: reduces the impact on the environment, controlling/reducing the greenhouse effect, and maintaining sustainability of energy resources for future generations

    Impact of Fossil Fuel Use

    • Electricity generation in Malaysia is highly dependent on fossil fuels, which emit carbon dioxide (CO2) and contribute to global warming
    • Increased energy efficiency can control/reduce the greenhouse effect and maintain sustainability of energy resources for future generations

    Air Conditioner Energy Consumption

    • Air conditioner at 18°C: 7.71 kWh/day, RM 4.40/day, RM 132.00/month
    • Air conditioner at 24°C: 4.88 kWh/day, RM 2.79/day, RM 83.70/month
    • Saving: RM 48.30/month, RM 241.50/month for 5 units

    Impact of Water Dispenser

    • Active Mode: 8687 Wh, RM 0.00
    • Passive Mode: 993 Wh, RM 17.00

    Impact of Lamp (Incandescent vs LED)

    • Incandescent Lamp: 100 W, RM 5.48/month, RM 109.60/month for 20 units
    • LED Lamp: 9 W, RM 1.23/month, RM 24.60/month for 20 units
    • Saving: RM 85.00/month

    SAVE 4.0 Program

    • A program that grants a maximum of RM400 e-rebate to domestic households that purchase energy-efficient air conditioners and refrigerators with 4-star or 5-star energy efficiency labels from the Energy Commission (ST) in 2021
    • Objectives: increase the total number of 5-star and 4-star energy-efficient electrical appliances and energy-efficient appliances in the market, and increase public awareness to encourage them to buy energy-efficient appliances that will save consumer's electricity consumption
    • Implementation period: 1 year from December 2023 to December 2024
