ARS Technica's "green pc" guide misses
Posted: Wed Feb 27, 2008 4:49 pm
Brian Won's article Ars System Guide special: it's easy being green focuses on reducing power and ignores the fact that 75% of a computer's environmental impact occurs before it ever gets into the hands of the end user.
Those who really want to make a difference will simply not buy new, keeping older gear running as long as possible or buying used gear that's lower power if possible. If you have to buy new, get the most minimalist system you can -- both size and power-wise.
Simple fact: The environmental cost of manufacturing far outweighs minor improvements in power efficiency for desktop computers. IE, if power efficiency reduces electricity consumption during use by 30%, the total environmental cost of the computer will drop by just 7.5%. (30% of 25% is 7.5%) This does nothing to change the upfront environmental cost of manufacturing.
Being green with computers is not easy at all.
