Measuring the carbon or greenhouse gas (GHG) footprint of an organization is a sophisticated undertaking. Traditional audit methodologies allow participants to "reduce" their footprints through externally-hosted IT and through "cloud" (SaaS) applications. This needs to change as more organizations become ICT-intensive.
Samsung's transparent LCD panel "utilizes ambient light such as sunlight, which consequently reduces the power required since there is no backlight...The transparent LCD panels have a high transmittance rate, which enables a person to look right through the panel like glass, and it consumes 90% less electricity compared with a conventional LCD panel using back light unit." Samsug's panels won a Eco-Design and Sustainable Technologies award at CES 2012.
Two technology advances point to the promise of more more energy-efficient memory. One is described as "nanoscale", the other "atomic scale". The latter comes with a video.
Interest in energy-efficient computing has sparked a Vertatique discussion of energy-sensitive benchmarks beginning in 2007. We originally saw pages per kilowatt hour, "MIPS / Watt" or "Flops / Watt" and Peter Kooge's "performance / joule". More have since been proposed, including one from focused on CO2e, but none have emerged as definitive.
Chemical batteries have a host of life-cycle sustainability issues, so ICT manufacturers and practitioners are constantly looking to innovate in this area. I've previously taken a look at alternatives to chemical batteries in ICT facilities and infrastructures. What about e-gear? Mitigate, more than eliminate, is the current state of practice.
Europe has a number of initiatives and conferences focused on the 'C' in "Green ICT'.
TREND is a Network of Excellence on energy-efficient networking funded by the European Commission within the Seventh Framework Programme (FP7). TREND describes itself as "a new holistic approach to energy-efficient and sustainable networking."
The ECONET (low Energy COnsumption NETworks) project is a 3-year IP project (running from October 2010 to September 2013) is also funded under FP7, addresses Strategic Objective ICT-2009.1.1 The Network of the Future (Euro-NF). "The ECONET project aims at studying and exploiting dynamic adaptive technologies (based on standby and performance scaling capabilities) for wired network devices that allow saving energy when a device (or part of it) is not used…The overall idea is to introduce novel green network-specific paradigms and concepts enabling the reduction of energy requirements of wired network equipment by 50% in the short to mid-term (and by 80% in the long run)."
Earth911 has created an info-graphic presenting the progress of the EPEAT® program. Among its statistics: the 411+ million registered items purchased since the program began in 2005 have eliminated 8375 tonnes of toxic material that would have be used in the manufacture of unregistered gear. (Summary readers can click "Read more" below to see the full graphic and all its information.)
Conferences covering the topic of "green communications" are plentiful this year. Some have March 2012 submission deadlines.
Facebook mentions in passing that its highly efficient Prineville data center uses "Ethernet-powered LED lighting [to] reduce the total energy required to run the facility." Additional information about what exactly Facebook has done is hard to fine. What is Ethernet-powered LED lighting?
Photovoltaic (PV) solar is promising source of on-site renewable electricity generation for ICT infrastructures. Solar PV generates DC power; computers and other e-devices run on DC power. What are the challenges and opportunities?
