Are Large ICT Companies Large Users of Renewable Energy?

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.

Finding the Greenest Set-top Boxes

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.

Latest Apple TV Box is Most Energy Efficient Yet

Apple TV STBThe 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 Makes Individual Business Groups Accountable For Carbon Neutrality

Carbon Neutral logoMicrosoft is "…making the commitment to become carbon neutral beginning with our Fiscal Year 2013 (which begins July 1st [2012])." 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.

How Green is the Microsoft Surface?

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.

PUE Still Above 2.0 for Most Data Centers

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.

Green ICT at DistribuTECH 2013?

steam plume from geothermal generationI 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?

ICT's Potential to Reduce GHG Still Outweighs Its Own Emmissions

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.

Non-Chemical Batteries Emerge for ICT Facilities and Infrastructure

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:
