Distinctive Features of a Green Computer
Let’s now take a look at green computer features--which will help you in determining whether the computer you’re buying is truly green or not. Most computer manufacturers have introduced a series of green PCs, but do investigate the following features to ascertain how green their computers are.
Low Use of Hazardous Elements: A lot of hazardous substances are used in the production of a computer ranging from the more lethal ones like cadmium, lead, chromium, and mercury to the relatively less hazardous ones like flame retardants, pesticides, and chlorinated plastics. A green computer's components should ideally be completely free of these lethal substances; thus IEEE environmental performance criteria requires the manufacturers of green computers to explicitly declare the percentage composition of these substances on the product. As for the less hazardous substances, the focus is on reduction of their use, since their elimination may not be completely possible.
Energy Efficient: That’s one feature of green computers that pleases not just environmental enthusiasts but also the budget-conscious buyer. Every green computer will have an energy star rating on it, and the more the stars the more energy efficient the computer will be. Some green computers are also available with the option of running them on renewable energy like solar energy, for which the manufacturers will supply you with all the required accessories.
Recycled Materials Used for Manufacturing: A truly green computer will have most of its components, especially the plastic ones, made of recycled materials. And the manufacturers are required to declare what percentage of material used in the production of the computer is recycled, with minimum thresholds specified at 10 percent. However, it’s more environmentally friendly to opt for a computer that’s built with more than 25 percent of recycled material. Ideally, printed circuit boards are the only things that may not contain recycled material.
End of Life Recovery: The green computers are designed in such a way that at the end of their life their components can be easily reused, disassembled, or recycled. A minimum of 65% of the parts of the computer should be recyclable or reusable. Apparently, some of the better brands of green computers guarantee a minimum of 90% reusable or recyclable parts. Also, the parts that are hazardous should be marked accordingly for easy identification and expert handling.
