A little knowledge goes a long way in saving energy
Television has long been regarded as something that no home can do without. Yet most people know little of what it costs. It may come as a surprise that TVs add more to Hong Kong's household electricity bills over a year than any other common appliances except air conditioners and refrigerators.
Environmental activists want consumers to have more information on the energy efficiency of the new generation of larger, flat-screen TV sets. As we report today, the green group Friends of the Earth has called for mandatory energy labelling along the lines of a law passed recently covering air conditioners, refrigerators and compact fluorescent light bulbs. The United States, for example, has adopted a new TV power consumption standard and the European Union is considering tighter regulations, including calls for a ban on plasma TVs, which use more power than liquid crystal displays.
The Environmental Protection Department has yet to decide what else to bring under the new labelling scheme, but environmentalists have a point. Few households have a need for more than one refrigerator, dryer, toaster or rice cooker. What sets TV and peripheral electronic products such as video and game-players apart is the increasing occurrence of multiple sets per household. Without information on energy efficiency, consumers focus on screen size and image resolution, without knowing the energy-cost implications over a long period of time.
TV is not to be compared with power hungry air conditioners or non-stop refrigerators. But every little bit of energy efficiency helps save fuel and combat global warming. And greater awareness would help encourage other good conservation habits, like not leaving the TV on in the background when no one is watching and turning off peripheral equipment such as cable boxes and video game consoles when not in use.
Given the revolution in home entertainment, mandatory energy labelling of TV sets is a good idea. It would enable consumers to make informed choices and protect the environment.
