Fuel cells, including those powered by biogas, are a growing part of sustainable ICT infrastructures.
We have been tracking the adoption of the Bloom Energy Server for ICT over the past three years. We've noted Bharti Infratel's use of fuel cells to replace diesel generators at off-grid telecom sites India. Here are more products and deployments; the most recent post is about Nokia's fuel cell technology.
Most Green ICT attention focuses on the datacenter. Five years of work consistently holds that datacenters represent a minority of total ICT energy consumption and carbon emissions.
Microgrids - small electricity generation and distribution networks - are becoming an increasingly common way to support ICT in remote areas. What distinguish a true remote ICT microgrid from a locally-powered remote piece of ICT gear like a base station? A microgrid is an integrated network consisting of one or more power generating systems, storage, control electronics and a diverse load. Imagine interconnected solar PV and with diesel generation backup powering not only that base station but also a community charging station for phones and tablets and a school's wireless router. To the extent that ICT microgrids support a significant proportion of renewable generation, they contribute to Green ICT and help bring urgently-needed sustainability to ICT4D. Here is a look at the big picture. Future updates will include implementations.
GSMA's Global Mobile Awards' Green Mobile Awards are for "mobile industry organisations that are focused on the reduction of environmental impacts through eco-friendly, innovative policies, products, programmes or initiatives, as well as organisations outside of the industry that utilise the mobile platform to communicate, innovate or drive eco-friendly programmes, services and initiatives." Here's a look at the 2009-2013 winners and at the trend toward greener mobile base stations.
Hong Kong's Green ICT Awards started in 2011, making them the oldest ongoing Green ICT recognition program* in the Asia-Pacific region. The roster annual winners illustrate the diverse nature of the area's ICT-savvy users and their Green ICT practices.
TV Whites Spaces (TVWS) are portions of the broadcast spectrum that, depending on your perspective, either are valuable unused frequencies or are usefully buffering against adjacent channel interference. The potential for TVWS to deliver wireless services is a major controversy in the United States between the wireless community and the broadcast community. Microsoft and Google are both using Africa to demonstrate the viability of delivering connectivity via TVWS with projects launched in early 2013. Microsoft launched another white spaces project in late 2013.
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.
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.
A number of sustainability rankings in the US and Europe let us take a look at how telecom providers perform compared to each other and to broader tech sectors. Sprint-Nextel is best in the United States. Sprint's take-back program was ranked tops in the US in 2012 and was the only carrier in the top quartile of Greenpeace's 2013 Cool IT Leaderboard. France Telecom, KPN and Vodafone have received consistently good marks with global rankings.
A MarketsandMarkets report says, "The global volume of e-waste generated is expected to reach 93.5 million tons in 2016 from 41.5 million tons in 2011 at a CAGR of 17.6% from 2011 to 2016." Three strategies for dealing with an organization's aging ICT gear are scrap, external reuse, and internal reuse. Internal reuse offers a growing number of increasingly sophisticated options while external reuse is revealing some unintended consequences.
