What do the people gain from the energy transition?


Shaping the energy transition according to the citizens‘ needs is essential for our work at the 100 prozent erneuerbar stiftung. What we know: The citizens in Germany want the energy transition. What we don’t know: What role can, want and should they play?

Will they shape the energy transition?
Will they remain supply cases without major changes because „The power comes from the socket.“?
Do they have to accept everything that the legislator and companies are planning?

We must assume that all of these three options describe very much possible and probable roles. Though it’s anything but arbitrary who – especially how many people – play which role. It’s crucial for the success of the energy transition that the people act a part they feel comfortable in.

Anyone who doesn’t want to shape the transition can remain in the classic role of a consumer. But what about those that are affected but are forced into this role? And what about the people that don’t want to be a supply case but a designer for the energy transition but can’t just do that?

In short: Our central question is „What do the people gain from the energy transition?“
The 100 prozent erneuerbar stiftung works out answers in their projects and cooperations.


Goals and values

Our goal: An energy supply consisting of 100 percent renewable energy that’s decentralized and collaborative. Because we want the energy transition for everyone!


We experience a new motivation to participate in many different contexts. We want to cultivate this motivation for the energy supply while integrating people that have faced energy issues with distance and indifference. Energy concerns everyone – because it is relevant for everyone. We want to make energy more perceptible and accessible and encourage the people to participate.


Decentralized means that the energy is produced where it’s consumed: close to communities in the city or in the country. A decentralized energy system is oriented towards the need on-site and offers integrative solutions – technical as well as economical. It mainly enables one thing: participation. We see systematic, technical, economic and especially social advantages in the de-centrality.

100 percent renewable

A safe, eco-friendly, independent from imports and in terms of price stable energy system – that’s what the transition from a fossil to a regenerative energy supply stands for. Transition means to reinvent the energy system and include the people. And of course, replace climate-damaging power plants with renewable energy.


The statute is the basis of our work at the foundation. It regulates our foundation’s goal and organization. Every year we account for our work at the foundation in form of our annual report and annual accounts at the supervision and service administration body in Trier. The statute is only available in German.

“My motto is: 100% dedication for 100% renewable energy. That’s why I am commmitted to that in many fields; because it’s not enough to install systems. We need creative ideas!”

It started with an orange tie and the imprint “100% renewable”: With this statement, back in 2007 very provocative, Matthias Willenbacher initiated the 100% renewable campaign to advertise an energy system consisting of the sun, wind and co. Out of this campaign he founded the 100 prozent erneuerbar stiftung in 2010. Matthias Willenbacher is an entrepreneur, investor and founder of juwi one of the biggest project developers for renewable energy systems in Germany and wiwin GmbH that was started by the juwi Invest GmbH. The studied physicist is also the author of the bestseller “Mein unmoralisches Angebot an die Kanzlerin” and contributed to the movie “Die 4. Revolution – Energy Autonomy”.

Harald Uphoff
Managing Director

Harald Uphoff has been managing director of the foundation since September 2021. In November 2022 he was appointed chairman of supervisory board of Bündnis Bürgerenergie (BBEn). The biologist was deputy managing director of the German Renewable Energy Federation (BEE) and at the same time managing director of the Bundesverband Deutscher Wasserkraftwerke e. V. (BDW), a member association of the BEE. Most recently, Harald Uphoff was head of the conflict avoidance department at the Kompetenzzentrum Naturschutz und Energiewende. As a mediator and moderator, professionally implemented participation processes in renewable energy projects are particularly important to him. This is the only way to achieve the necessary rapid expansion of renewable energies in the future.

Unsere Jahreshefte geben einen umfassenden Einblick in unsere Stiftungsarbeit. Wir arbeiten rein operativ. Das bedeutet, dass wir ausschließlich eigene Projekte finanzieren und durchführen. Die Projekte sind dem Stiftungszweck, dem Schutz der Umwelt durch erneuerbare Energien, verpflichtet. Die Erfüllung des Stiftungszweckes wird durch die Aufsichts- und Dienstleistungsdirektion Trier geprüft.


Wir vergeben regelmäßig Stipendien für Forschungsvorhaben im Bereich der Erneuerbaren Energien. Aktuell fördert die 100 prozent erneuerbar stiftung folgende Vorhaben:
