I posted last week that I would be attending DistribuTECH and asked about Green ICT there. How credible is the sustainability vision of Smart Grid, Smart Buildings, etc. if the Smart community does not attend to the sustainability of the Smart infrastructure?
We noted in a 2008 post about the SMART 2020 report that while ICT emits GHGs, its potential to reduce them in other sectors was 5X greater. Now, a follow-up report - SMARTEer2020 - calculates ICT's leverage at 7X.
What is a battery? A device to store energy and convert it to electricity on demand? This is an important question as ICT facilities and infrastructure elements increasingly rely on sophisticated battery-based systems such as UPS. Potentially greener alternatives are emerging to chemical batteries, with flywheels appearing to have the most momentum for ITC facilities going into 2013.
Let's start by reviewing the role energy storage devices play in ICT. A 2011 APC white paper lists three applications:
Verne Global continues to publish useful information about why customers value green data centers. Automobile manufacturer BMW is the latest customer profiled by the company.
Microsoft has announced plans to spend $5.5 million to build a zero-carbon data center pilot project in Wyoming. A source of very low carbon electricity is key to such projects. Microsoft's power generation fuel? Municipal sewage!
Two Green ICT threads have converged in the natural disasters of Japan's earthquake/tsunami and America's hurricane Sandy. One is how energy-efficient gear, infrastructures, and practices can contribute to more sustainable ICT. The other is how efficient ICT can combine with renewable energy sources to deliver education, medicine, and other basic services to areas with little or no dependable electricity. From this converge comes a vision of sustainable ICT with is both efficient and resilient.
There are many examples of where a focus on equipment utilization can be more sustainable than other green ICT tactics. Here are some examples.
Google offers frequent updates on its Green ICT progress. Here is the most recent, along with past updates.
Photos, inside and out, of Google's data centers. Note that most locations include a reference to some green initiative.
This has not been detailed on Google's useful blog, but Grist reports that "Google’s new $700 million data centers in Taiwan will make ice at night, when electricity is significantly cheaper, and use it to cool the buildings during the day."
Google announced in January 2012, "All of our U.S. owned and operated data centers have received ISO 14001…certification. We’re the first major Internet services company to gain external certification for those high standards at all of our U.S. data centers." Here are some of the specifics.
A Microsoft/Accenture/WSP report compared three applications used in-cloud and on-premises. A Google report takes a similar look at Google Apps. Both claim CO2e reductions ranging above 80%. Pike Research says the move to cloud computing will decrease overall data center GHG emissions by 28%. The most recent report, a WSP/NRDC study, reinforces these themes but offers balancing perspectives.
