Materiality is one of the most unknown aspects of digitalisation. It results in enormous infrastructures located all over the planet and even in its orbit that need immense amounts of mineral and energy resources. Explore these and other “dark sides of the cloud” with us!


When we think of the cloud, we imagine it as something ethereal, light and dematerialised. We don’t visualise the millions of devices, thousands of kilometres of cables, gigantic data storage, and processing centres, or the satellites that make up its immense infrastructure. We don’t conceive the enormous amount of mineral, water, and energy resources required for its operation. Nor the environmental impacts resulting from their production and disposal.

Digital technologies have undoubtedly brought great advances for humanity. However, if we want to continue to benefit from them in the future, as well as from a healthy environment, we must delve deeper into that dark side of the cloud and correct its pernicious effects. This is especially relevant at the present time, with European post-covid policies pushing for digitalisation as a key element for economic recovery. And not only that, this endeavour aims to face multiple crises, including the global supply crisis; the energy crisis aggravated by the war in Ukraine; and an increasingly worrying climate and environmental crisis.

These will be discussed in this series, as well as alternatives for a more energy-efficient, sustainable and long-lasting digitalisation.



The series “The dark side of the cloud. The environmental impact of the virtual” is organised by the Green European Foundation (GEF) in collaboration with Fundación Transición Verde and La Casa Encendida.

It will take place on 20 and 27 October and 3 November, from 18:00 to 19:30 (CEST) and consists of the following round tables.



The event is online, open and free with prior registration through this form. The activity will take place in a Zoom room. Once registration has been completed, and before each session, a confirmation email will be sent with the access details for the meeting.

Simultaneous translation service Spanish-English will be available in all sessions.
