The International Electrotechnical Commission (IEC) is working on a standard that would measure how much electricity plasma or LCD televisions consume.
Concern over power consumption of LCD and plasma TVs brings a sense of urgency to environmental agencies and government regulators anxious for a way to obtain power measurements on LCD and plasma TVs, claims the IEC.
Reducing per model TV energy use by 25% by 2009 could save more than 10 billion kilowatt hours (kWh) per year in the U.S., said the IEC.
TV broadcasters and manufacturers edited together a mix of different genres spanning soap operas, nature programmes and sports and assessed the proportion of broadcasting for each type of genre in the world.
This is because the power needed by a television for the images varies according to the type of programme broadcast, said the IEC.
The programme will be contained in a new IEC standard that offers a way to measure power consumption and provides manufacturers with a means to provide accurate energy label ratings for consumers, said the IEC.
Energy Star distributed the IEC standard to manufacturers to draw up specifications.
Policy-makers in other parts of the world will be able to use the IEC standard to define their energy saving directives, said the IEC. European policy makers, for example, are considering an energy efficiency index that examines watts per square screen centimetre or inch.
