What makes the cooperative model so special – and why is it indispensable for the energy transition? We spoke with Thomas Jorberg about this. The long-standing spokesperson of the management board of GLS Bank and current chairman of the supervisory board at EWS is more familiar with the cooperative concept than almost anyone else. In the interview, he explains the opportunities citizen participation has created for renewables, why cooperation is crucial for the future – and how energy cooperatives can help make green electricity affordable, secure, and socially relevant.
Käthe & Paul: Mr Jorberg, what is your personal connection to energy cooperatives?
Thomas Jorberg: I grew up professionally with the cooperative GLS Bank. The cooperative principle is fundamentally linked to a mission to promote certain goals. This includes investing money in ways that align with those goals. After the Chernobyl nuclear accident, many people – including the founders of Prokon – saw a secure and clean energy supply as part of that mission. The GLS Bank has been involved in this area since the early 1990s.
K & P: What is special about the cooperative model?
Jorberg: The cooperative is the only economic organisational form where, as a shareholder, you don’t take the potential value with you when you leave. There may be a dividend in between and the return of your contribution in the end, but the future value remains within the cooperative enterprise. That means: the cooperative belongs to its members, but it essentially serves the defined promotional purpose.
K & P: You are the Chairman of the Supervisory Board at EWS, which originally started as a citizens' movement. Why was that important?
Jorberg: Citizen participation was the fundamental prerequisite for the rise of renewable energies from sun and wind. The large fossil-fuel-oriented energy corporations had no interest in it and didn’t take it seriously. So, we had to use citizen engagement to demonstrate that renewable energies are a viable alternative – and today we know: the only truly sensible one. Prokon, with the commitment of its members, is also an example of this.
K & P: Recently, the industry has been facing headwinds – politically, but also socially. How do you assess this?
Jorberg: For a while, we had a lot of tailwind – thanks to the Renewable Energy Act (EEG) and improved framework conditions. That has now changed. I see two main challenges for us: Renewable energies need to prove that they can guarantee security of supply. And prices should be such that everyone can afford green electricity. Only then will the topic reach all levels of society. The energy sector clung to centralised structures for too long. For renewables to become reliable and affordable, we need the networking of different generation sources – including hydropower and biomass – as well as decentralised storage solutions and intelligent management of consumption.
"Through economies of scale within a cooperative network, energy cooperatives can demonstrate that green electricity through direct supply is affordable even for average earners."

K & P: Doesn’t that take far too long?
Jorberg: Essentially, it’s an infrastructure issue. The raw materials – wind and sun – are already there, they just need to be converted, transported and controlled. This is about investment, not ongoing costs. Over the past 20 years, we’ve seen such rapid technological development in this field – I’m convinced it can go faster and become cheaper than many claim.
K & P: But someone has to pay for it – and not everyone can afford green electricity even now.
Jorberg: That’s due to segmentation. From landowners to marketing companies, there’s often a gold rush mentality: everyone wants to earn as much as possible at every stage – that drives up the system’s cost, and ultimately everything ends up in the electricity price.
K & P: How can that be solved?
Jorberg: The cooperative mission should cover the entire value chain – from project planning through construction and operation all the way to direct marketing to customers. I envisage a cross-functional collaboration of energy cooperatives, where each contributes its individual strengths. Such an “Associative Energy Cooperative” would have the necessary societal and economic relevance, and could use cost advantages to demonstrate that directly supplied green electricity is affordable even for average earners. If the key players join forces in a cooperative alliance, we could easily reach one million electricity customers. That would also make it attractive for investors. This way, energy cooperatives could become a true benchmark – safe, climate-friendly, peaceful and affordable. Ultimately, it’s also a peace project, because energy policy resilience prevents conflicts over securing resources.
Thomas Jorberg, born in 1957, was with GLS Bank from 1986 until the end of 2022, serving as Spokesman of the Executive Board for the last 20 years. He was honoured as "European Banker of the Year 2021". The graduate economist has been Chairman of the Supervisory Board of EWS in Schönau since 2005 and President of the Board of Directors of Weleda AG since 2021. Jorberg delivered the keynote speech at Prokon's anniversary celebration.
