Global Green ICT Update: Asia-Pacific

Short updates from Asia-Pacific. Click here for regional Green ICT updates from around the globe. Click on 'Asia-Pac' tag above for all news about the region. Our latest item looks at mobile growth in the region.

The New York Times reported in July 2016 about China's growing Bitcoin mining industry. The article's energy-consumption figures suggest that 40% or more of global Bitcoin mining now takes place in China. Photos show these mining centers looking more like aging industrial buildings than gleaming modern data centers, but energy-sourcing issue are the same everywhere. We've noted how energy availability plays a big roll in siting data centers and Chinese Bitcoin mining is no different. "[One operator] said he had become an expert in finding cheap energy, often in places where a coal plant or hydroelectric dam was built to support some industrial project that never happened. The Bitcoin mining machines in his facilities use about 38 megawatts of electricity, he said, enough to power a small city."

"Energy Harvesting" Powers Small Wireless Devices

We've been tracking the potential of "energy harvesting" to power devices without conventional batteries or grid connections since 2011. The latest market entrant demonstrates this segment continues to expand.

Freevolt from Drayson Technologies Limited "...provides power for Low Energy Internet of Things (LE-IoT) devices. Its a...technology that harvests radio frequency (RF) energy from wireless and broadcast networks such as 2G, 3G, 4G, WiFi & Digital TV... Freevolt technology can extend device lifetime by constantly trickle charging the battery and removing the need for battery swaps or plug-in charging." Freevolt was recognized as a 2016 Sustainia 100 solution. The Sustainis citation noted the technology's potential for ICT4D. "Freevolt enables the cable-free installation of connected devices in hard-to-reach or dangerous location, bringing off-grid charging to rural markets."

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.

Broadband Access Can Drive Citizen Participation in the Smart Grid

One of the six goals in the US National Broadband Plan (NBP) is

Goal No. 6: To ensure that America leads in the clean energy economy, every American should be able to use broadband to track and manage their real-time energy consumption.

The Role of ICT in CleanTech

Clean Tech is technology that reduces the consumption of resources (like energy) and the emission of toxins (like CO2e).

All aspects of Clean Tech will depend on ICT - information and communications technology. You can see below some of ICT's potential across a spectrum of Clean Tech applications.

It is important that the huge growth of the ICT infrastructures necessary to do all this are as sustainable as possible. Clean Tech needs Green ICT to stay clean, itself.
