Fun With Environmentalists
Next time your low impact, vegan, think globally act locally, anti-globalisation, protesting, Gaian, be nice to your mother environmentalist irritates you, find out if they use a computer. If they do, hit 'em with this:
According to the study, the manufacturing of one desktop computer and 17-inch CRT (cathode ray tube) monitor requires at least 240 kilograms of fossil fuels, 22 kilograms of chemicals and 1,500 kilograms of water. In terms of weight, the total amount of materials used is about equal to that of a mid-size car....Make sure they writhe in guilt.
Users should think carefully about whether they really need a new computer, if upgrading their existing computer could serve the same purpose, he said. Actions such as delaying replacement and upgrading the memory or storage space or, if the machine is replaced, donating the old computer so that it may continue to be used offer potential energy savings of between five and 20 times those gained by recycling.
This is because so much of the energy required to manufacture a personal computer is used to make high-tech components like semiconductors and those components are destroyed in the recycling process to collect a small amount of raw materials. In an earlier study published in late 2002, Williams concluded that 1.7 kilograms of fossil fuels and chemicals and 32 kilograms of water are used to produce a single 2-gram 32M-byte DRAM (dynamic RAM) memory chip.
