Interviewer
Gaming is a resource-intensive industry. What can Germany do to improve sustainability in
this sector?
Michael Kellner
Parliamentary State Secretary at the Federal Ministry for Economic Affairs and Climate Protection, Germany
Well, a very small point, but also one with a huge effect: use green electricity for this. […]

Or simply gift gamers photovoltaic cells on their roofs.
Is that enough?

•RQ1 How can the power consumption of video games be measured?
•RQ2 How high is the power consumption and efficiency of individual components
(e.g., graphics or physics) inside video games?
•RQ3 Which technical factors influence the power consumption of video games?
•RQ4 How can we inform and educate stakeholders about the power consumption of
video games in the most beneficial way?
•RQ5 How can video games and video game engines integrate organic computing
techniques to adapt to different environments and usage scenarios, resulting in a
more sustainable and reduced resource usage?
•RQ6 How can stakeholders be enabled to customize the power consumption
behavior of video games?
Research Questions
5FDG 2025 - Achieving Green Computing in Video Games Using Power Measurements and Organic Computing Techniques - Julien Lukasewycz
1. Energy Awareness
Establish a baseline of current power
consumption in video games
•Develop a method and tool able to
measure the power consumption of
video games and their components
•Measure the power consumption of
concrete video games and identify
factors influencing it
•Create a broad research data set and
statistics
Approach
6FDG 2025 - Achieving Green Computing in Video Games Using Power Measurements and Organic Computing Techniques - Julien Lukasewycz
2. Informedness
Make power consumption data usable
by developers and players
•Identify the information needed and the
most effective visualization style of
power data for developers and players
•Use measurement data in combination
with estimations or benchmarks to
predict power consumption
•Implicitly trigger a learning effect by
associating decisions and their effects
on power consumption
Approach
7FDG 2025 - Achieving Green Computing in Video Games Using Power Measurements and Organic Computing Techniques - Julien Lukasewycz
3. Self-Adaptability
Video games autonomously adapt
their power consumption based on
their state and environment
•Use organic computing techniques that
delegate and limit resources based on
the given task
•Make video games more adaptive to the
specific hardware components of the
device
Approach
8FDG 2025 - Achieving Green Computing in Video Games Using Power Measurements and Organic Computing Techniques - Julien Lukasewycz
4. Customizability
Let developers and players influence
the self-adaptability behavior
regarding power consumption
•Developers configure the initial power
usage behavior of the video game
during development
•Players customize these initial
configurations to better match their
device, environment, and preferences
using simple decision questions or more
complex power settings

The End (at least of this talk)
11FDG 2025 - Achieving Green Computing in Video Games Using Power Measurements and Organic Computing Techniques - Julien Lukasewycz
Thanks!
I wish everyone a fantastic conference!
1. How can prototypical concepts be integrated in (released) closed-source video
games and video game engines?
2. How could cooperation in research projects be achieved, and which concrete party
or type/genre of video game might be the most open for collaboration?
•Which incentives or benefits can be offered to parties to get involved with the topic?
3. Furthermore, how can measurements inside closed-source video games be
conducted?
•Which alternative approaches could be applicable?
•How can measurements (using profilers) be done in real time and inside the exported video
games?
You may also provide me with general feedback, improvements, or extensions and hint at possible challenges that might arise.
