City governments can show Green ICT leadership. Paul Kronberger, CIO of Madison (WI-USA), a city of 270,000 residents, tells me the municipality has taken these steps to improve the sustainability of its own operations.
In an ironic turn of events, the e-waste being reprocessed in China is coming home to us through imports. This includes lead1 in our food.
Wearable tech is of interest to Green ICT because it can drive miniaturization and energy efficient. Miniaturization can reduce resource consumption in the creation of ICT gear and reduce e-waste in its disposal. Miniaturization combined with energy-efficiency can enable a host of applications ranging from "smart building" sensors to compact assistive technology. Is more wearable tech all positive? We look at a number of global trends and technologies.
ICT companies appear to be boosting their use of renewable energy. Indicators include the Vestas 2012 Corporate Renewable Energy Index (CREX) and Apple's recent announcement about progress toward its 100% renewable goal.
The US ENERGY STAR program looks only at energy efficiency and not other sustainability factors. About twenty set-top boxes (STBs) or cable, IP, or satellite from seven manufacturers came in at less than 65W in the program's Total Energy Consumption (TEC) metric. This is a big improvement from two years ago, when our top twenty cut-off was 100W.
The Apple TV set-top box (STB), which I own, has always been very energy efficient. It is consistently at top the of EPA's ENERGY STAR STB ratings. Now, a third-party test finds the 2013 edition to be the most efficient Apple TV yet.
Microsoft is "…making the commitment to become carbon neutral beginning with our Fiscal Year 2013 (which begins July 1st )." Top-down enterprise initiatives can founder on local accountability, as when IT departments do not pay their data centers' electric bills. Microsoft is trying to avoid such pitfalls with the internal equivalent of a carbon tax. the 'tax' money is being invested in carbon offset and renewable energy initiatives.
Apple attracted attention in 2012 because its iPad was so tightly assembled that it was not easily recycled. Now, it appears that Microsoft's Windows Surface tablet may be even less easily recycled.
We've worked to achieve a global reach and now welcome 60%+ of our visitors and followers from outside of the United States. In 2013, @GreenICT became the #1 ranked global Twitter feed for #GreenICT and the #2 for #GreenIT by wefollow.com.
We could not have accomplished this without all the support of our site visitors and Twitter followers, particularly those who referenced and retweeted us. Thank you!
A 2010 version of this post was titled "No One Can Agree on Typical PUE". I wrote, "As more data centers measure their PUE, more and more ask what is typical? The industry does not seem to agree, so a wide range of numbers are out there." I updated the post in 2012 with the latest data, concluding that most data centers still appear to be operating above a PUE of 2.0."
I put the question to Vertatique's global Green ICT community in August 2013 via a tweet: "After years of #GreenICT, is there evidence that most #datacenters now operate below PUE 2.0?". This was one of our most-retweeted, but no one came forward with new evidence. Some replied in the emphatic negative. I concluded that the 2012 analysis, below, still stands.
