BT Trials "Cool Broadband"

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.

ICT Facilities Look to Renewables

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.

$122 Billion To Be Invested in Energy Efficient Telecom Infrastructure

According to Pike Research, "capital investment in energy-efficient network equipment will reach $122 billion by 2014, representing 46% of the total network infrastructure market...The opportunity is largest for mobile network operators, which we expect will represent almost two-thirds of the green telecom market. This focus is especially relevant as mobile operators deploy 4G networks at scale over the next few years."

Europe Completes GHG Audit for a Large R&E Network

As we learn that most ICT impact occurs outside of the data center, understanding the the impact of "CT" becomes as important as that of "IT". GÉANT, the multi-gigabit pan-European research and education (R&E) network, has completed an GHG audit of its network backbone using the ISO 14063 standard. Its report both offers insights and raises questions.

The Debate About What Is Truly Clean/Green Energy for ICT

Recent posts about "green" cloud computing generated lots of response. The issue: what is "green" and "clean" energy?

Volcanoes and Data Centers

I wrote last year about Verne Global's selection of Iceland as a location for a green data center based on the country's location-specific attributes. Recent news about the large ash emissions from the Eyjafjallajokull volcano prompted me to check back with the company. Lisa Rhodes, VP of Marketing and Sales at Verne Global, offered insight on both siting and operational issues.
