FOSS Energy Efficiency Project (FEEP)

How can you measure software's energy consumption? And does it make a difference? We are working to make free software more sustainable.

Blauer Engel For FOSS (BE4FOSS)

Eco-labels for products are used widely already. But how can they be transferred to software? What criteria is relevant? We need more pioneers to find out how we can make software sustainable.

KDE Eco - Building Energy-Efficient Free Software

KDE supports the FEEP and BE4FOSS programs to help free and open source communities produce more environmentally friendly software. The projects provide communities with guidelines and support to optimize software to be more energy efficient and have a longer life-span.

Let’s make energy efficient software and digital sustainability part of our community! We can live up to our responsibility for this and future generations!
