Like other areas of business, information technology (IT) is making shifts towards environmentally-sound processes and systems. Green computing refers to the use of computer resources in an eco-conscious way. It involves developing, utilising, and recycling technology to reduce environmental impact. Green IT not only benefits business owners but also the community as a whole.Green computing prevents waste of resources and reduces carbon footprints. It works on all levels, including the development stage, the manufacturing phase, the usage, and the disposal of computers. Everybody has a role to play when it comes to green computing whether at work or at home, or even in the manufacturing plants.How Businesses can Ensure Green ComputingModifying the way we use and dispose computers can minimise the negative impact it has on the environment. There are different ways to ensure environmentally-conscious use of computers. For example, businesses can use energy-efficient hardware such as liquid-crystal-display (LCD) monitors instead of cathode-ray-tube (CRT) monitors as these tend to consume a lot of energy.In workplaces, workers can power-down the computers and the entire peripherals when not in use. Furthermore, the use of notebook computers instead of PCs can help to reduce the consumption of energy. There are power management features incorporated in the operating systems of the devices and, if used appropriately, they can help minimise waste.Why Campaign for Green ITWhen you know that you are employing environmentally-friendly tactics, you get satisfaction. You are happy that you are contributing to saving and protecting Mother Nature. Implementing green computing also has some financial paybacks. For example, you can reduce your electricity bill when you use energy-efficient computers and peripherals like printers.Green computing helps improve people’s health and promote biodiversity. When computer parts are recycled and reused, it means fewer chips and other computer components will end up in a dumping field somewhere. This then means that there will be less contamination of water resources and a reduced side effect on plant or animal life.
