This is solar-powered base station on top of a mountain in Lapland (Finland).
Remote ICT infrastructures are embracing renewable energy for everything from earthquake mitigation in Japan. CO2e reduction in India to . Fuel/power costs appear to have gone down since 2009 for off-grid mobile operations, but are still significant. Asia leads world in current renewable base stations and in growth potential. One operator - Indus Towers - now has 20,000 zero-diesel sites.
Electronic media infrastructures and gear are important components of global ICT as movies, television, music, and books all go digital. This post offers a global sampling of sustainability in e-media. A green production app is our latest find.

Location is becoming increasingly important to the sustainability of ICT facilities. We've been tracking facilities in North American and Europe which try to leverage geographic features for greener operations. Our latest examples in the North America section of this post show how under-utilzed grid power is also making some locations attractive.
were critical of Apple's environmental stance a few years ago, saying that the company was positioned to be a leader rather than a a foot-dragger. Since then, the company has made significant strides, such as improvements to its take-back recycling programs*. On the downside, issues about its Chinese contract manufacturing operations have been slow to be resolved. Recent actions toward addressing labor issues need to be matched with ones addressing environmental issues. Factory pollution takes a toll on both workers and neighbors and a July 2013 report alleges problems still persist. Yet Apple continues to improve its environmental position in China - producing solar power is its latest initative.
"E-waste" and "cyber waste" describe the unwanted systems and components of our industry. Green organizations and facilities mitigate their e-waste impacts by repurposing and recycling equipment when scheduled for replacement. Despite all the focus on e-waste over the past decade, it continues to pollute communities around the world and threatens global ICT infrastructures. Yet no one cal agree on how much is actually out there.
ICT gear depends on materials whose supply is increasingly affected by environmental and political factors. This gives rise to a complex set of issues ranging from resource scarcity to conflict minerals.
We documented how the e-waste America ships overseas returns to threaten it's citizen's health. Now, we've learned how that e-waste also threatens America's national security.
A 2010 version of this post was titled "No One Can Agree on Typical PUE". I wrote, "As more data centers measure their PUE, managers ask what is typical? The industry does not seem to agree, so a wide range of numbers is 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.
Three years of very enlightening survey results from Digital Realty, including the 2014 data, confirm that the 2012 analysis. The only lower (better) average PUE came from Microsoft.
Supercomputer manufacturers have always vied to build the most powerful machine. Recently, they have sought to increase energy efficiency, as well. Yet innovation appears to be slowing. The most recent ranking still shows the top performer to be China's Tianhe-2, a position it obtained in June 2013. (Tianhe translates as "Milky Way" in English.) An american supercomputer installed in Switzerland is the most energy-effieicnt of the Top 10 machines.
