The importance of electricity in present day life needs no explanation. But everyone is worried about the escalating electricity charges. Do you feel that your electricity bill does not commensurate with total appliance used and the level of comfort enjoyed? Is your family budget affected by the power tariff? If the answer to any of the above questions is “yes,” you urgently need an “Energy Audit’”. This is a scientific method to find out and avoid wastage of energy and to ensure better utilisation of available resources, there by increasing profit.

Here are some useful tips that can be tested easily at home and would give amazing results. What is one “unit” of electricity? Power consumption is measured by the unit ‘kilowatt-hour’ or simply the “unit”. It is the energy consumed by an equipment having a rating of 1000watts when used for 1 hour The commercial consumers are charged highest whereas the agricultural ones the least.

  1. Air conditioner
    It is the size of room, number of occupants etc that determine the capacity of the AC. A 1½ tonne AC unit consumes 2-2.5 unit electricity even for one hour! If the air holes are hermetically sealed off, the consumption can be considerably reduced. Higher level of insulation of rooms especially those below the roof, reduces the heat entering the house and makes any cooling system more effective and efficient. The AC should not be allowed to perform with faulty thermostat as extra energy is required to bring down the temperature.


  2. Computer
    Computer is not a current intensive unit. It is the monitor which consumes the most Electricity. Music lovers listen to the CDs for hours together in multimedia computer. The monitor can very well be switched off at that time or set the computer to sleep after 10 minutes of inactivity.


  3. Fan
    A ceiling fan in operation throughout the night will gobble up 22 units in a month. There is a wrong notion that fan at more speed would consume more current. Fan running at slow speed would waste energy as heat in the regulator .The ordinary regulator would take 20 watts extra at low speed. The energy loss can be compensated by using electronic regulator. Old fans when in use produce unwanted noise. This may either be due to faulty bearing or loose top, which need attention.

  4. Refrigerator
    Domestic fridges are the cause of wastage of electricity in majority of houses. An ordinary single door 165 lts fridge would consume 30-35 units a month .10 years or older fridge would consume 1 1/2 times more energy and require immediate renovation or replacement. If the fridge is not closed properly, the temperature inside may increase and make the compressor work more. Hence open the doors only when required and keep them open as briefly as possible.


  5. Domestic lighting
    A major portion of domestic consumption of electricity goes to meet the lighting requirements. The main source of light in our home is the ordinary bulb, which unfortunately happens to be the main culprit in wastage of electricity. Only 5% of the electricity used by the bulb is converted to useful light and the majority to heat. This has the least efficiency .

    In many houses, there are decorative lamps, serial sets or “zero watt” bulbs displayed on photos. These are lit through the day and night.

    At the time of finalising the plan and sketch of a building, there should be clear idea about the lights inside. The location of window and ventilator should be such as to maximize the utilisation of natural light.
