Ask The Experts: Green Information and Communication Technology

Submit your questions on how to make devices more eco-friendly

17 February 2016

The greenhouse-gas emissions produced globally by information and communication technology (ICT) account for more than 2 percent of the worldwide total—and that percentage is expected to double by 2020. In our March issue, The Institute explores the many ways the IEEE Green ICT Initiative is working to reduce the sector’s carbon footprint.  

Here to answer your questions on how to make technology more energy efficient are two leading experts in the field. To participate, submit your questions to them in the comments section below or e-mail us at Institute@ieee.org. A selection of questions and their answers will be published on our site on 31 March.

IEEE Senior Member Jaafar Elmirghani is the co-chair of the IEEE Green ICT Initiative, which is helping the telecom industry become more energy efficient and is working with ICT companies to develop standards for green technologies. He is the director of the Institute of Integrated Information Systems and chair of the communication networks and systems department at the University of Leeds, in England. His research has helped identify ways to improve energy efficiency, including a sleep mode to power-down equipment when network traffic is low.

IEEE Member Thierry Klein leads the GreenTouch consortium technical committee. The consortium is composed of experts from 48 information and communication technology companies, as well as academia and nongovernmental organizations. Its members include Alcatel-Lucent Bell Labs (now Nokia), China Mobile, and Swisscom. The group’s goal is to improve the energy efficiency of communication networks by a factor of 1,000 by 2020 compared with those in use in 2010 (the year the consortium was launched), all without compromising performance and while supporting the larger traffic volumes expected.
