Oct. 2012 Winners of the energy saving competition rewarded A representative group of winners of the Energy saving competition for the month of October 2012 was rewarded at a ceremony organized by CEBs The winners were given away certificates of appreciation for the energy saving effort by Hon Minister of Power Energy
CEB engages in a roadside campaign to educate the public 2012/06/11 CEB appeals to the public to save electricity and help them to manage the current hydro storage until significant rainfall is received as the storage has fallen to 27% of the total capacity Leaflets carrying Tips for efficient use of household electrical appliances were distributed aiming the family unit
Tips for efficient use of household electrical appliances 1 of 6 Switch off the lights when moving from one room to another Use CFL bulbs with 5 STAR label that saves 80% electricity instead of ordinary bulbs Install windows in the places where maximum of natural lights are received while designing the houses Clean the dusts on the bulbs more often so that you can get maximum light Use the light to the required place like using a reading lamp when studying
Tips for efficient use of household electrical appliances 2 of 6 Buy a refrigerator to suite the requirement of the house Reduce the number of opening times of the door of refrigerator. Do not store hot food in the refrigerator. Wrap vegetables and fruits in polythene covers and store in the refrigerator. Store liquids in closed containers. Then the release of moisture will be limited and the electricity consumption will be less.
Tips for efficient use of household electrical appliances 3 of 6 Iron clothes of few days instead of ironing clothes every day. Start from rough cotton clothes and end in soft clothes. Switch off electricity connection and Iron soft clothes using the already heated iron Use irons with automatic heat controllers Do not iron wet clothes.
Tips for efficient use of household electrical appliances 4 of 6 Buy a washing machine suitable to the quantity of clothes for washing. A washing machine with a capacity of 5kg is sufficient for a family with 4-6 members. Front loading machines are more efficient than up loading machines. Therefore, try to buy a front loading machine Reduce the number of washing times. Wash clothes of several days at one time.
Tips for efficient use of household electrical appliances 5 of 6 Try to use electric fans instead of airconditioners Pedestal fans and table fans are more energy efficient than ceiling fans Cover the windows of the air-conditioned rooms so that the air will not go out Use curtains and grow trees if the direct sunlight comes to the air-conditioned rooms Leave the temperature control at 26 C. Reduction of 1 C will result in the increase of 4% in the cost.
Tips for efficient use of household electrical appliances 6 of 6 Do not use only the remote controller to switch off the television but use the switch on the television as well. When a colour television is in stand-by mode it consumes 18-25 watt of electricity
