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?
Oracle's latest Next Generation Data Centre Index compares today's situation ("C2") with that of a year ago ("C1") for Europe and the Middle East. Findings are positive but mixed from a Green ICT perspective.
Email and email attachments have less environmental impact than physical delivery. But email is not without its own costs, both in terms of energy/carbon footprints and organizational productivity. A French company has taken a hard look at this and announced that it will move toward "zero email". At the same time, a German company has stopped its servers from routing some email after hours.
UK's Waste & Resources Action Programme (WARP) conducted a study of the Waste Electrical and Electronic Equipment (WEEE) content of Household Waste Recycling Centres (HWRCs). What can we learn, besides UK greens' fondness for initials? Turns out media, not IT, gear is the largest category. Upgrades are driving this waste stream.
Vertatique's comprehensive vision of ICT includes e-media infrastructures and practices. News Corporation one of the world's largest media empires, so the company is a logical one for us to track. We first began looking at NewsCorp in July 2006, when company executive (and chairman's son) James Murdoch talked about the media industry going green. Among his claims back then: NewsCorps' satellite broadcasting arm BSkyB is already "carbon neutral".
UK telecom provider BT is working on broadband delivery technology that varies its power in response to demand.
The "latest generation of Asymmetric Digital Subscriber Line (ADSL) line cards - which allow up to 20Mbit/s broadband speeds on the last mile of the network - [operates] in an 'always available' rather than 'always fully on' mode…BT’s network infrastructure currently accounts for more than 60 per cent of its carbon footprint and the access network represents a large part." BT reports this new tech - called "cool broadband" - is still under development, but has already been used in a small customer trial.
CME Group Index Services publishes the Dow Jones Sustainability Indexes. Which ICT companies perform best on the 2011 Indexes?
ICT facilities of all kinds are increasingly looking to complement energy efficiency with sourcing renewable energy. We found ISPs already using renewables when we launched Veratique in 2007 and a couple of years later noted the first US television station to use wind power. Now we see diesel being replaced by renewables to power remote telecom facilities. Data centers are also part of the trend.
