If you have been exceptionally successful at cutting your electricity consumption, we will invite you to share how you achieved this and celebrate your success during our Earth Hour 2019 launch ceremony in 30 March 2019.

Individual Challenger

A reduction of 1% of total electricity consumption over a miniumum six-month period in 2018 (when compared to corresponding months in 2017) is your target!

You will need electricity bills received in 2017 and 2018 for entering your electricity consumption Submit Electricity Consumption. Refer to our guide if you encounter problems during data entry. Please enter your data no later than 4 January 2019. If you have lost some of your electricity bills, we will help estimate the missing consumption on your behalf.

Your name will be listed on our webpage if you achieve the target of 1% reduction of total electricity consumption.

If your electricity consumption reduction is far greater than other challengers, we may contact you to ask that you share how this was achieved, and to celebrate your success during our Earth Hour 2019 launch ceremony. In the spirit of fairness, we may request that you provide us with copies of your electricity bills.

Feel free to contact us (852) 2526 1011 if you have any questions.

School Challenger

Tips for Saving Electricity

Everyone

  • Turn off electrical appliances when not in use. You save 1kWh (=1 unit) of electricity by switching off the following:
    • 4W LED light bulb 250 hours
    • 150W laptop computer 6 hours and 40 minutes
    • 250W desktop computer 4 hours
      The above is for reference only. The actual energy saving depends on the power input (wattage) of a particular appliance.
  • Use natural lighting and light zoning in the home/school/office. This means turning off lights near windows during daytime. Make sure the light switches are individually marked so staff and students know which switch is for which lights.
  • Ensure energy-saving settings (eg sleep mode) is used on computers and other appliances.
  • Set the air-conditioning (thermostat setting) to 24 degrees Celsius in the winter and 26 degrees Celsius in the summer.


Individual Challengers

  • Choose energy-efficient electrical appliances. A Grade 1 room air-conditioner of 1 Horsepower could save up to HK$480 in electricity cost annually compared to a Grade 5 model. A Grade 1 refrigerator can save up to $380 per year.
  • You can calculate the electricity running cost of air conditioners, refrigerators, washing machines, dehumidifiers, televisions, water heaters, etc. based on the brand and model, from the EMSD’s website https://www.emsd.gov.hk/energylabel/en/cal/cal.php#.
  • Reverse Cycle Air-conditioners (RCAC) can help save 50% of energy use compared to fan heaters. (source: CLP)
  • Use electric fans with air conditioners to increase the circulation of cool air. You could save up to HK$50 each month by turning up the air-conditioner temperature by 2-3 degrees. (source: CLP)
  • Standby power accounts for as much as 5-10% of total power consumption. Use a smart plug/panel to cut off your standby power. (source: CLP)
  • Take a 5-minute-only shower by using Grade 1 energy labelled electric water heater with a Grade 1 water efficiency label showerhead can save up to HK$70 in electricity cost. (source: CLP)
  • Fully load the washing machine as half loads use the same amount of energy as a full load.
  • Clothes ironing uses up to 1,800 watts of energy, and consumes up to 1.8 units of electricity if used for one hour. Remove clothes promptly from the washing machine to minimise ironing needed.


School/ Corporate/ Organisation Challengers

  • T5 fluorescent tubes consume 20% less power than T8 fluorescent tubes.
  • Use 7-day time switch to turn off all office equipment after office hours, which can add up to 5-20% in energy savings.
  • Choose the variable frequency drive (VFD) for air-conditioning systems. By reducing air or water flow rate by 20%, the VFD can save up to 50% of energy.
  • Use heat pumps to act as a source of hot water supply. Compared to electric and gas heating, heat pumps use about 35-50% less.
