Abstract

There is increasing pressure on higher educational institutions (HEIs) to cost cut and adopt sustainable approaches to reduce power consumption, reuse and recycle of the ICT equipment’s and systems. ICT has a significant impact in higher educational institutions but there are several consequences which may be positive or negative in terms of cost and power consumption. The information and communication technology (ICT) sector has been grown exponentially in the modern age. An essential aim of the ICTs under study is to determine how to reduce power consumption, apply refurbishing, reusing and recycling practices for ICT equipment’s in HEIs. These ICT equipment’s are responsible for emission of high amount of Green House Gases (GHGs) and consumes huge amount of energy. Ethiopia is one of the developing countries where power scarcity is already a big issue and required to develop strategies that can encourage power savings. In this concern Ethiopian HEIs are huge amount of power consumers in which the energy consumption analysis of current situation has to be executed. Developing countries face numerous challenges like strategic alignment in energy efficient techniques to reduce power consumption, refurbishing, reusing and recycling of the ICT equipment with proper mechanism. As a matter of fact, African continent country’s HEIs are still reluctant in adopting the energy efficiency standards practices. It was observed that these HEIs do not analyze energy efficiency and adopt green standard practices for reducing, refurbishing, reusing and recycling of the ICT equipment. This research thesis analyzed the current green ICTs usage in higher education institutions and selected an organization Arba Minch University (AMU), Wachemo University (WCU) and Wolaita Sodo University (WSU) for primary data collection and case observation, investigation and analysis. Finally the research developed a green ICT framework for reducing power consumption, reusing, refurbishing and recycling the ICT equipment in in educational institutions. The researchperformed experimental analysis using dynamic voltage and frequency scaling technique (DVFS). The simulation technique was used and implemented DVFS with VM migration to support research results through experimental analysis. Simulated experiments found that the overall energy consumption of the ICT center is approximately decreased by 95 % for the given configuration of the ICT center equipment. The use of this technique can be assumed as significant contribution to reduce energy consumption, minimize environmental impacts and also can reduce the CO2 emission especially in reference to AMU, WCU and WSU ICTs centers. The data during survey and interview was collected using Google form, framework was designed using E-draw-max and CloudSim toolkit was used for simulation and onal demonstration
