Actually, in terms of overall electricity usage in households, air conditioners use the most on a continual basis, followed by refrigerators. But on a unit per hour basis, air conditioners are not that bad, even though they’ve been made the villain by the media. Broadcasters, in particular, are offering tips to households on how to cut down on energy consumption and the main suggestion is to set your air conditioner at 28 degrees centigrade. Because so many people, in particular the elderly, have fallen victim to heat stroke, no one is saying to turn off the air conditioner any more, but the general consensus is that the average air conditioner in the average home uses about 130 watts of energy and, overall, accounts for a bit less than a fourth of the summer electricity bill, which gives you some idea of the savings potential.
What the media doesn’t say, according to an article in the most recent issue of Shukan Post, is that there is another appliance in your house that actually uses more electricity. A typical large screen (over 37 inches) LCD television set uses on average 220 watts, or 70 percent more energy than the air conditioner if both are being used continuously, but, of course, media companies aren’t going to suggest you turn off the TV because that would hurt their business.
