Beginning of the journey
Heinrich Gärtner was born in 1972 in the small town of Husum,
Germany, and from the beginning, he was deeply influenced by his
idyllic surroundings. The vast, rolling fields and the gentle whispers
of the North Sea fueled his fascination with nature. Early on in his
life, he realized that nature held the key to our future, and that
realization would become the cornerstone of his life‟s work.
Heinrich Gärtner studies with Ove Peterson at the Weihenstephan
University of the Applied Sciences, holds a degree in agricultural
engineering, and likewise runs an agricultural business.
After completing his engineering studies with top honors, Heinrich
Gärtner co-founded GP JOULE in 2003 with Ove Petersen.

2. It was a pivotal moment in his life, as it marked the beginning of a
journey filled with challenges and triumphs. The company name was
inspired by the physicist André-Marie Ampèr, reflecting their
commitment to harnessing energy responsibly.
GP JOULE and its remarkable journey
It all started with small solar plants, as Heinrich Gärtner and Ove
Petersen had already been putting PV projects into practice on their
farms for a few years. In 2009, the two agricultural engineers
decided to use their knowledge and experience to found a new
company and gave it their initials: GP JOULE.
Their vision for the company was to supply transport and society
with 100% renewable energies, and their stance was to respect all
partners and take on responsibility for the environment and future
generations.
The initial years of GP JOULE were marked by resourcefulness and
an unwavering vision. Heinrich led the initial charge and worked
tirelessly to secure funding for the company„s ambitious projects. His
persuasive abilities and passion for renewable energy convinced
investors that GP JOULE was not just a business venture but a
movement aimed at changing the world.
One of the company‟s first major achievements was the construction
of the Green Hill Wind Farm. This wind farm is located on a
picturesque hill overlooking Husum and soon became an iconic
symbol of GP JOULE‟s commitment to green energy. Heinrich often
said, “The wind that once whispered to me in this town now powers
it.”

3. In 2012, GP JOULE entered the green hydrogen business. The first
wind farm planned by GP JOULE was connected to the grid, and the
first GP JOULE solar parks were opened in Italy and France.
After their initial success, the projects kept coming: GP JOULE
expanded its vision to Canada and the USA, and later to Ireland and
Italy, in order to plan, project, and install solar parks there as well.
The green revolution was everywhere, and it was thanks to GP
JOULE.
As GP JOULE continued to grow, Heinrich‟s leadership was marked
by innovation as the company pioneered advancements in solar
technology and was able to develop highly efficient photovoltaic
systems that were able to convert sunlight into electricity with
unprecedented precision. This innovation made renewable energy
accessible to a broader audience, from homeowners to large-scale
industrial projects.
Heinrich‟s dedication to sustainable development has also led to
groundbreaking partnerships. He collaborated with local
communities to establish Solar Co-ops which allow residents to
collectively invest in solar installations and reap the benefits of
clean energy. These initiatives not only reduced carbon footprints
but also empowered individuals to take control of their energy
future.
In 2023, Heinrich Gärtner assumed the role of Chief Technology
Officer (CTO) of the GP JOULE group. His responsibilities extended
beyond the day-to-day operations of the company, as he became a
global ambassador for sustainable energy solutions. He spoke at
International conferences, sharing his insights on clean energy

4. technology and policy and inspiring governments and organizations
to prioritize renewables.
Under his guidance, GP JOULE has been able to develop cutting-
edge storage solutions that address the intermittent nature of
renewable sources. Their battery systems became integral to the
stability of energy grids, ensuring that clean energy was not only
abundant but also reliable at times.
Heinrich‟s life has come full circle. From the fields of Husum to the
global stage, he demonstrated that a passionate vision, unwavering
commitment, and dedication to innovation could transform
industries and impact the world in a better way. His story was a
beacon of hope, proving that sustainability and success could go
hand in hand.
Today, GP JOULE stands as a testament to Heinrich's legacy, a
legacy that continues to shape the future of renewable energy. As
for Heinrich himself, he remains a revered figure in the field, a
storyteller of change who reminds us that the power to create a
sustainable world lies within our group.
