Green IT strategy

Updated on November 26, 2012

A brief idea on Green IT strategy

Also known as Green computing or ICT Sustainability, Green IT refers to environment friendly computing. It aims at reducing the use of hazardous materials, promotion of biodegradability or recyclability of factory waste and defunct products. Many big IT companies are taking the initiative of adapting this method, so as to minimize the harmful impacts which IT operations have on the environment. The key areas where research is being carried out are making computer-usage energy efficient to the maximum and designing systems and algorithms for efficient computer technologies.

Causes for this attention:

 The high rise in the cost of energy over the last five years. The incremented publicity of energy citizenship and global warming. Increase in the legislation surrounding greenhouse gases (GHG), energy efficiency and toxic m

Issues with the present IT system:

Issues with the present IT system:
During the weekends the desktop PCs and servers remain fully powered, thus creating a pressure at the data centre, for the cooling purposes, carbon dioxide is emitted in the atmosphere. This is extremely harmful for the environment, as it leads to global warming, in the process of giving power and cooling the data centres, a lot of electricity is needed. This is one of the costliest aspects in the department of IT, lack of facilities is one of the major issues, expensive and inefficient methods of cooling, issues related to the hardware, high-density energy-intense servers and due to inattentiveness and lack of awareness results in the consumption of energy at an excess rate and exploitation of IT equipments.

Practices associated with Data Centre:


Elimination of energy leaks, exploring alternative energy sources, and reconfiguring data centre floor layouts, using alternative storage tactics, using more efficient and innovative cooling methods and using virtual servers instead of high-density servers.

Practices associated with End-User Computing:


Change the purchasing habits of IT assets, energy-saving settings should be enabled on the computer, recycling and proper disposal of IT assets should be practiced.

Benefits from Green IT:


Reduced emission of carbon and other green house gases.
Data centres have increased cooling efficiency.
There is a positive publicity.
The financial performance is improved.
A lot of cost savings.
The energy cost is much reduced.

What are the drivers?


Increase in the price of electricity over the past years, the major concerns are power and cooling systems, high increasing average storage and public awareness and legislation to study environmental impact on IT.

The challenges:

The challenges are creation of energy-efficient systems that can be operated within a targeted power and the future DCs need to be built in a modular way such that the power consumption can be scaled with the growth.
The concept of Green IT is very eco-friendly. Taking into consideration, the condition of our planet presently, it is very important to adapt this system.
