Computers are made of poisonous materials like lead, chromium, cadium and mercury. If computers are buried in landfill, they can leach harmful chemicals into waterways and the environment and if burned release toxic contaminants into the air we breathe. Computers consume energy and no-one has come up with a practical solution for the potential environmental disaster of millions of obsolete computers hitting landfill sites around the world.
Computers can also be harmful to your health because toxic chemicals evaporate in a computer room, are absorbed by your body through your lungs. The radiation that is emitted from computer monitors can pose a serious health risk especially to those with long hours of exposure.
How To Apply Green Computing?
Reducing energy consumption by PCs
We can significantly reduce energy consumption by making small changes to the ways we use computers. Most personal desktop computers run even when they aren’t being used, because users needlessly leave them on, wasting electricity. Furthermore, computers generate heat and require additional cooling, which adds to the total power consumption and cost for the enterprise. While the savings in energy costs per PC may not seem like much, the combined savings for hundreds of computers in an enterprise is considerable. We can reduce PC energy consumption by adopting several measures
Enabling power management features.
Without sacrificing performance, we can program computers to automatically power down
to an energy-saving state when we aren’t using them.
Turning off the system when not in use.
This is the most basic energy conservation strategy for most systems. Many people believe
the misconception that a computer’s life is shortened by turning it on and off, so they
leave their computers on all the time. The electronic equipment’s life span depends on
its cumulative operational time and its temperature. Turning it off reduces both of these
factors, increasing the life of the equipment.
