-===== Definition of Green IT ===== 
-Green IT refers to the study and practice of using computers and IT resources in a more efficient and environmentally responsible way [McCabe, 2009]. The objective of green IT is to minimize the negative impact of IT operations on the environment by designing, manufacturing,​ operating and disposing computers and computer-related products in an environment-friendly way. The motives behind green IT practices include reducing CO2 footprint, limiting the use of hazardous materials, maximizing energy efficiency during the product'​s lifetime and promoting the biodegradability of unused and outdated products. 
-The process of green IT starts with manufacturers producing environmentally friendly products, continues with IT departments using more energy efficient technologies and ends with proper recycling habits. This detailed view is defined by San Murugesan who notes that green IT includes "​designing,​ manufacturing,​ using, and disposing of computers, servers, and associated subsystems—such as monitors, printers, storage devices, and networking and communications systems — efficiently and effectively with minimal or no impact on the environment"​ [Murugesan, 2008]. This definition also outlines the scopes of green IT and the computing resources that are involved in it. 
-The study and practice of green IT is getting more and more important every day as IT is responsible for 2%-4% of Green House Gas (GHG) emissions, growing with penetration rate and individual usage explosion. Moreover, the reserve of rare materials - such as gold, silver, copper and antimony - are depleting with the increased consumption,​ whereas, IT alone uses more than 25% of these rare natural resources and with an increased rate every day [Guibard, 2013]. Along with these numbers, there is an amount of 73M tons which is the estimated e-waste to be produced by IT in 2015. Statistics are not for speculation,​ they are true. And all these statistics illustrate the significance of green IT at present.
