Set-top boxes (STBs), many with embedded DVRs, have become fixtures in American households. These devices, required for many digital televisions (DTV) services, and are rented from cable, satellite, and telephone companies or purchased from companies like Apple (Apple TV) and Google (ChromeCast). The proliferation of electronic devices have been frustrating household energy-saving measures and STBs, even when not in direct use, are no exception. A December 2013 agreement should result in more energy-efficient STBs.
Bitcoin is an extra-sovereign currency which maintains is scarcity by requiring increasingly complex computer calculations for their creation. This process - bitcoin mining - highlights a number of Green ICT issues. Increased public awareness of Bitcoin could help awareness of Green ICT.
Several companies have been working to create cloud computing volume servers using "wimpy chips". These are low-power, lower-speed chips designed for mobile devices. The idea is that large numbers of these in a server can yield lower energy consumption while maintaining cost-effective performance. The EU has launched an initiative using the wimpy-chip approach, but an American pioneer has shuttered its doors.
The 'education' tag, above, will lead you to all sorts of stories about educational institutions around the world that are incorporating Green ICT technologies and practices. These range from the public universities in the United Kingdom to African schools in cleverly-configured shipping containers. What is missing are signs of wide-spread adoption of Green ICT by America's colleges and universities even where 'green' is the focus. A review of various 'green' lists illustrates the problem.
We launched Vertatique with the statistic that data centers consumes ~2% of global electricity production. We now know that the globe's broader ICT energy footprint is ~8%. The explosion of telecommunications and mobile devices has helped drive the number higher despite gains in ICT efficiency. Here are the facts and figures.
The Great East Japan Earthquake of March 2011 and its tsunami had a huge impact on the country's ICT infrastructure, much of which is still being felt by businesses and consumers. Here is an update on the information and insights we have collected about data centers, communications networks, e-devices, and other ICT topics.
Global consulting company Accenture announced in March 2013 that it "…has been awarded a contract to create the strategic plan to help develop the University of Aizu Revitalization Center. The plan includes construction of a technology lab on the university campus as well as support for projects focused on rebuilding Fukushima as a technology leader. Accenture’s plan calls for the lab design to begin this year, with construction expected to be completed in the spring of 2015. When completed, the lab will feature a next generation data center, an efficient, high-performance center that will consume about 40 percent less electricity than traditional data centers." Telecom Asia notes that "The Revitalization Center was established to aid recovery of the area following the [earthquake]." A September release from Accenture announces that the company has been awarded a contract work on the design the ICT laboratory, itself.

Supercomputer manufacturers have always vied to build the most powerful machine. Now, they routinely increase energy efficiency, as well. The most recent addition to this ongoing article looks at the current top performer, China's Tianhe-2.
We first noted the potential of "energy harvesting" to power devices without conventional batteries or grid connections a couple of years ago. The latest research shows the "Ambient Energy Harvesters" (AEH) market growing at a CAGR of 17%. The latest technology harvests energy from microwave signals.
Apple has been making in big investment over the best couple of years to make its newest data center 100% powered by renewable energy. It has how announced a similar objective for a new US-based manufacturing facility in Arizona. This should contribute to reducing the embodied CO2e in Apple's products.
