Scientists at the Cologne Institute for Economic Research have determined that when it comes to energy consumption and carbon dioxide emissions a TFT monitor (or Flat Panel Display) that is either turned off or left in standby mode results in a 1W difference.
Hendrick Biebler and his fellow researchers at the Institute say that concentrating on standby mode is diverting attention from the real objective of improving overall efficiency of electronic devices. They argue that a EU directive aimed at outlawing standby mode is wrong headed and could stop manufacturers from improving the energy efficiency of products. Recently the European Union has adopted a framework directive on requirements of the ecodesign of Energy-using Products (EuP). An implementing measure on standby energy consumption based on this directive is expected in 2008.
Prof Biebler and his team say the important issue is to phase out old, energy-intensive components, pointing out that an old CRT computer monitor uses 75W, compared with 25W for a modern TFT screen. Attempting to regulate the off mode is the most expensive option that saves the least amount of energy when it comes to producing more environmentally friendly electrical devices.
