SR P1-morgon: Computers the new eco-scoundrel? [SE/EN]

"Är datorn den nya miljöboven? (webbradio)

IT-användningen i världen påverkar klimatet nästan lika mycket som flygindustrin, det visar en ny rapport som Håkan Nordin, TCO development tagit fram. Vi har också besökt kontorsarbetare som förklarar varför de inte stänger av datorn när dom går på lunch eller möte."

Executive summary:
PCs may at first seem inconspicuous from an ecological point of view, but there are so terribly many of them so their energy consumption (which makes up 70% of the problem) is enormous in sum. According to some calculations, the climate impact of the world's IT use is nearly as large as that of air traffic!

In a new report by TCO Development, whose main author Håkan Nordin was interviewed in Swedish public radio this morning, a typical office computer spends as much as two months per year running in spite of not being used (while the human is having lunch, in meetings etc.).

A few tips for office users:
  • Quite a lot of people obviously still believe that a screen saver saves energy. Sorry, that is complete nonsense: the computer is still running, as is the monitor, so they happily consume energy!
  • Find and activate the energy-saving settings of your computer (most computers in question run Windows, and Windows positively has these settings)!
  • Overcome your laziness... Do press the power switch on your monitor if you go away! Modern LCD displays take no longer than 1, 2 seconds to come on again once you are back.
For home users hunting for a new PC, Håkan Nordin recommends to pester the sellers with questions about the efficiency of the different models. A system with cheap, inefficient components may use up to 8 times as much energy as an equivalent efficient one!!

Also noteworthy: Another considerable part of the global IT consumption stems from the data centres feeding the internet.
