> recently compared the
|
|
energy consumption of different computer types along the life cycle. The
|
|
production of computers actually needs 535 kWh which is 10 % less than 4
|
|
years ago. Most of the energy will be consumed while the computer is used
|
|
for example at work for 8 hours/day. The energy consumption of new
|
|
computers with 2,5-3 GHz processors is even in the
|
|
stand-bye-mode still 100 Watt, whereas a 1,4 GHz PC needs 80
|
|
Watt and a 4 year old PC only needed 60 Watt. Therefore from the
|
|
ecological point of view it is better to buy an old computer
|
|
that didn't need the energy for a new production and which
|
|
consumes less electricity while it is being used.

> LCD displays need less energy than other monitors. For this reason
|
|
laptops are the most ecological types of the compared computers. They
|
|
need the smallest amount of energy when they are used. And 3 year old
|
|
laptops are better than new ones since their processors need less
|
|
energy than new examples. There is also an article in the
|
|
German computer magazine
