The right idea at the right time -
Company with positive energy

Company profile

An idea becomes a company. The company history begins in 1996 with the foundation of Vento Ludens by Horst Walz. The intact nature there fits the company philosophy of our family business: Embedded in the community, we are a trustworthy employer for the people from our region. With an eye for the environment and a corresponding inner attitude, we realize innovative projects with state-of-the-art technology.
The idea of generating energy through wind power turns into a vision: independence from fossil fuels and nuclear energy. In order to successfully advance this vision, after a short time we expand our range to include solar energy. Since the foundation of the company, we have continuously developed our expertise in the field of wind energy and photovoltaic systems.

From this knowledge, the next logical step is the expansion of our technologies into the field of hydropower plants. The exchange and the close connection with the Vento Ludens subsidiary in Switzerland, founded in 2009, contribute decisively to our success. We not only handle projects in the field of renewable energies, but also make a significant contribution to sustainable energy supply with our plants. We combine our forces in a targeted manner in order to make a significant contribution to the energy supply with enthusiasm and dedicated work.
Nature gives us all the resources we need to do this. We use them.
Mindful. Efficient. Respectful.
