Energy conservation
15-Jul-2017


In March 2017, the subsidies provided on electricity and water by the Government to the expatriates was enhanced again and the consumers are paying more costs of their energy bills. The situation now calls for more concerted efforts to reduce electricity and water consumption which we often take for granted based on its availability. We now need to save energy, money and support environment. 

We need to audit our energy and water consumption at our home and work and need to see how we can reduce our consumption and be environmental friendly. For electricity, we need to see how many bulbs, tube lights and illuminations we have for lighting, which equipment is causing what electricity usage. 

Follow these energy-saving tips to help fight air pollution, global warming and reducing our energy bills.

Use Natural Light: Avoid illumination in the day by optimizing the use of natural light. Keep off the curtains based on the light required or use light and see through curtains enabling more passage of sunlight.

Shift to LED Lights: Change the current illumination to Light Emitting Diode (LED) bulbs and lamps for energy-efficient lighting. LEDs present many advantages over other common incandescent light sources including lower energy consumption, longer lifetime, improved robustness, smaller size, faster switching, shock resistance and greater durability and reliability. 

LED light bulbs are a cost-effective option for lighting our homes, offices and facilities and can reduce energy consumption by 80% and carbon footprint by 68%. 

Switching it off: Develop the habit of switching off the lights and electrical appliances, soon after its use and especially during peak hours of the day (1-4 pm & 10pm- 1am). Make “switch it off when done” a smart household habit for all lights and devices, from computers to game consoles and TV.

Minimize Standby Power Use: Electrical devices constantly draw power even if the circuit running them is opened, or off. The LED indicator lights draw standby power for internal clocks in VCR or microwave etc. We can minimize standby power use by unplugging devices which are not frequently used.

Heating and Cooling: It can make up to 40% of a home’s total electrical usage. Check thermal insulation and repair any leakages. Depending on the climate, heaters and air-conditioners can run continuously. Minimize use of heaters and use ceiling fans with ACs to save electricity. Set the AC thermostat to 23C. Use fresh air when it is pleasant in the morning and late night.

Avoid Using Lounges: We often sit in large spaces with few users in our leisure time. Avoid using lounges and use other rooms for casual sitting and watching TV saving illumination and cooling charges. 

Avoid Equipment: Dry clothes in the sun instead of dryers. Avoid excessive illumination. Keep fans and lights on as you need. 

Cleaning and Servicing:  Clean your light bulbs regularly, since dirt limits diffusion of light and decreases illumination. Use timers or motion-detectors with lamps where applicable. Clean or replace AC filter bi weekly or at least monthly enhancing efficiency.

Use Appliances Efficiently: Avoid opening the refrigerator frequently. Defrost it regularly. Check its gaskets and seals. 

Use of Energy Efficient Appliances: Discard and sell old electrical appliances and equipment as they consume more eelctrcity. Buy and use energy efficient appliances. Use small cooking appliances (electric fry pans, toaster ovens, etc.) whenever possible depending on the quantity.

In addition, once you get your EWA bill, do find time to read the energy conservation tips mentioned on its back.
