The environmental impact of software and hardware systems has become a pressing concern. While mainstream operating systems like macOS and Windows provide proprietary tools to analyze energy usage, Linux—the cornerstone of open-source computing—lacks comparable capabilities. To address this gap, we present PowerLetrics, an open-source framework enabling detailed, per-process energy footprint analysis on Linux systems.

Our study in collaboration with Prof. Dr. Verena Majuntke from HTW Berlin and dena (German Energy Agency) has been published!

The content is the analysis and recommendations for action for politics, companies, research and civil society on how green coding can contribute to sustainable digitalization and reduced electricity consumption.

Our Green Metrics Tool has been awarded the Blue Angel for resource and energy efficient software! Details: Blog article / Product page on Blauer-Engel.de

Unser Pitch bei den WSA Awards für Green Coding Solutions und das Green Metrics Tool.

Wir sind stolz und glücklich 🤩, bekannt zu geben, dass die Green Coding Solutions GmbH einer der diesjährigen Gewinner des Green Screen Catalyst Fund ist! Als eines von 15 Unternehmen, die aus über 350 Bewerbungen ausgewählt wurden!

Damit wird die Entwicklung eines unserer Tools zur Evaluierung des Energieverbrauchs im Linux-Kernel - und damit die Einsicht und Quantifizierung der Energiekosten von Software auf Prozessebene - ermöglicht und weiter unterstützt.

Vielen Dank an die Green Screen Coalition 🌱 (Ariadne, Ford Foundation, Internet Society Foundation, Mozilla Foundation, Green Web Foundation, Critical Infrastructure Lab und die Mercator Foundation) für die Finanzierung dieses bahnbrechenden Fonds 🙏.

We have been tasked by the dena (Deutsche Energie Agentur) to make a hopefully groundbreaking study on Green Coding als Standard in der Softwareentwicklung für eine stromsparende Gestaltung der Digitalisierung.

In the Tagesspiegel background feature, our CEO Arne Tarara talks about the CO2 and energy costs of AI models and how to deal with them. how these are dealt with. Transparency is key to managing the risks properly.

In the Süddeutsche Zeitung dossier entitled “Deep Dive: Initiative promotes focus on green coding” we are interviewed on our ambitons and goals with the Eco Compute 2024.

“Ecocompute: The devil is in the details”

Datacenter-Insider.de is giving a detailed Re-Cap on our Eco-Compute conference in 2024. Worth a read

We were interviewed at Grüne-Startups.de about the content and concept of the Eco-Compute conference. Why is the approach with digital sustainability in hardware and software so unique and what are our goals for April.

In the e-tailment feature, we talk about green coding, especially in online stores. Where leverage points are, but also new approaches to stand out from the competition with a sustainable and CO2-conscious store.

In this Gründerszene feature, we talk about green coding specifically for start-ups. What you should pay attention to when setting up an IT startup and wanting to avoid CO2 emissions with digital products.

The increasing energy consumption of software and hardware systems has become a significant concern due to its environmental impact and operational costs. While operating systems like Windows and macOS have proprietary, undocumented energy analytics functionality, this feature is still lacking in Linux. In this paper we introduce PowerLetrics, an open-source framework designed to monitor and analyze power consumption metrics on a process level on Linux.

The environmental impact of software is gaining increasing attention as the demand for computational resources continues to rise. In order to optimize software resource consumption and reduce carbon emissions, measuring and evaluating software is a first essential step. In this paper we discuss what metrics are important for fact base decision making. We introduce the Green Metrics Tool (GMT), a novel framework for accurately measuring the resource consumption of software. The tool provides a containerized, con- trolled, and reproducible life cycle-based approach, assessing the resource use of software during key phases. Finally, we discuss GMT features like visualization, comparability and rule- and LLM-based optimisations highlighting its potential to guide developers and researchers in reducing the environmental impact of their software.

Conference publication at HotCarbon 2024 - We present a paper to reduce the energy consumption of LLM inference by using specialized open source models selected by a classifier beforehand.

Veröffentlichung in Future Generation Computer Systems - Das Green Software Measurement Model integriert Ergebnisse von 12 Gruppen von Forschern und Praktikern. In unserem Teil beschreiben wir, wie professionelle Energie- und CO2-messungen mit modernen container-nativen Open-Source-Werkzeugen durchgeführt werden können.

Publication in the GI conference proceedings of EnviroInfo 2023 - Software Life Cycle Assessment (SLCA) is gaining attention for its environmental impacts in production, deployment, usage, and disposal. Unlike LCA for physical products, SLCA is still evolving in software.

Concepts Towards a Life Cycle Assessment of Software - We are sketching out how software emissions over it’s whole lifecycle can be attributed with current tools and methodologies including future challenges and issues.
