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.

Finding the Greenest Tablets

The availability of tablets suitable for Green ICT purchasing has declined percipitously over the past year. We could identify only three manufacturers offer one model each. The sluggish global market for tablets may account for manufacturers' lack of interest in certifying new models.

Finding the Greenest Office Equipment

Many Green ICT certification and registration programs cover categories of office equipment other than the major ones for which we publish separate articles. (See list to the right.) Our latest update revealed no new categories and no overall increase in the number of models available. We also note an EPA-recognized toner cartridge remanufacturing initative.

Finding the Greenest Mobile Phones

A full update of this survey is planned for June. In the meantime, we are noting an achievement by USA carrier Sprint.

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.)

Finding the Greenest Computer Monitors and Projectors

There are hundreds of green-certified computer displays available and available models in most categories have increased since 2017. Here is how to find the most sustainable displays, including projectors, listed by international certification services.

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.

Newsweek's Green Rankings: ICT Comapnies Lose Dominance

ICT companies show less dominence of the top slots than they did five years ago. This is true in both US and Global rankings.
