Cryptocurrency Mining Is a Significant Component of ICT Electricity Consumption

We've tracked the growing environmental impact of cryptocurrencies like Bitcoin since 2013. It now appears that the cryptocurrency mining's GHG footprint is equal to that large cities. This is not good news for the planet.

We previously cited an estimate that put 2006 energy consumption of search engines at about that of the United States city of Las Vegas. It now appears that cryptocurrency mining can make a similar claim about its GHG footprint. Science Daily reported in June 2019 on the findings from a team of researchers at the Technical University of Munich (TUM). "The use of Bitcoin causes around 22 megatons in CO2 emissions annually -- comparable to the total emissions of cities such as Hamburg or Las Vegas." One reason this number is so high is the location of mining operations. "...the team was able to localize 68 percent of the Bitcoin network computing power in Asian countries, 17 percent in European countries, and 15 percent in North America." Asian electricity production tends to be more coal-based than other regions.

Green ICT Innovations

Researchers and businesses are advancing innovative ideas with potential for mainstream Green ICT. These range from products and services available today to futuristic concepts for tomorrow. The latest is Dell's gold recycling program, including the creation of jewelry from motherboard gold.

Green ICT Conferences

The most comprehensive directory of Green ICT conferences, workshops and other events around the world. Latest additions are events in France and Croatia.

Vertatique has started a listing of calls for papers for Green ICT publications.


Number of Green ICT Conferences Continues to Plunge Worldwide

The number of Green ICT conferences and workshops to decline, now to only half as many as in 2013. They have almost disappeared from North America and Asia/Pacific, with Europe hosting over half. The good news is that we listed one in Africa and one in the Middle East.

More Efficient Supercomputers

Energy efficiency is becoming more important to supercomputers, as ever more powerful machines consume ever more energy. Japan and the United States lead energy-efficient supercomputing. (A liquid immersion ExaScaler module of the top machine - Shoubu system B - is pictured to the left.)

How Fast Is Global E-waste Growing?

The most recent update on global e-waste from a consortium of international organizations gives us new data about the problem's scope and grow. Per-capita e-waste growth is slowing, the overall amount is growing with the world's population.

E-Device Metals Sourcing Bigger Problem Than Just Conflict Minerals

The issues around the use of metals in e-devices is more complicated than just the matter of conflict minerals. A recent report suggests devices might be more sustainable if they used more plastics and less metals.

Greenest Telecom Providers

An update to this topic shows there are fewer resources available to evaluate the sustainability of telecom company operations. Sprint and AT&T are the 'best' USA companies, but are ranked well below other ICT companies, including global telecoms. BT Group is the global green leader.

Green ICT Progress in Primary/Secondary Education

Our latest update is about a missed opportunity for Green ICT purchasing. Click on the 'education' tag and you'll see more examples of Green ICT being applied educational institutions of all levels around the world..

The Importance of Location for Green Data Centers

Location is becoming increasingly important to the sustainability of ICT facilities. We've been tracking activities which try to leverage geographic features for greener operations. This article focuses on Europe and Asia. (Another focuses on North America.) Our latest update highlights the relationship between renewable energy availability and overall desirability for siting data centers.
