YOU WILL soon know how much the electrical appliance you are planning to buy will add to your monthly electricity bill. Each appliance will have an energy-efficiency-cum-rating label pasted prominently on it. The lowest rating will be one star, which means that the product is a heavy energy consumer.
And the highest rating will be five stars - for products that consume the least energy. If you buy a five-starred appliance instead of a one-starred, the monthly energy saving will be 27 per cent.
The label will also give you the average energy consumption of the appliance in one day. "To start with, tubelights will have energy-efficiency ratings from mid-November," said Ajay Mathur, director-general, Bureau of Energy Efficiency, Ministry of Power. Next in the line will be refrigerators, air conditioners and television sets.
The move to introduce rating system has started showing results. Mathur said a particular refrigerator company replaced the insulation, reduced the number of wires and made changes in the compressor of its product to make it more energy efficient. The bureau follows a three-level process. At the first level, tests are conducted at the company's own testing facility.
The second tests are carried out at a competitor's laboratory. The final tests are conducted at a government-approved national testing laboratory.
