Abstract
This study focuses on the technology purchasing decisions of a mid-sized firm (500 employees) that increase the energy efficiency of its computing systems while meeting its business objectives. For example, if company growth requires implementation of a more robust and up-to-date customer tracking system and includes hiring 10 new employees, what course should be followed to ensure a reduction in energy consumption as well as the achievement of company business goals? Should the company purchase a couple of additional servers with limited capacity for growth or should the company replace 20 aging rack servers with six state-of-the-art servers for consolidation and the hosting of virtual machines? And should the company supply the new employees with new cathode ray tube (CRT) monitors or recycle some that have been in storage? There are several alternatives that the firm can use to achieve its goals. This paper evaluates four energy efficiency technologies with respect to their impact on the reduction in energy consumption as well as internal organisational processes and human aspects. A proposed research effort is expected to contribute to energy efficiency literature by capturing adoption decisions from a market – end-user – perspective, and the outcome of this study is proposed to give insights to energy efficiency programme managers into designing more accurate energy efficiency programmes.
