“The G7 internship program has provided me with exposure to wind energy far beyond my expectations. From the first day at G7 I was encouraged to take over own responsibilities and deal with various aspects of each project. Field works, workshops, access to information and the possibility to share my own ideas and contribute value to the company have brought me to a point where I feel fully integrated into G7 and identify myself with its vision.

The international, collegial but sharp focused working environment keeps on feeding my interests and the team is giving me the opportunity to grow in every field, on both a professional and personal level while in the mean time enjoying pioneering of wind energy in South Africa. All in all I am very happy to be offered this once in a life time opportunity.”

Kyler Bruno

“The skills I developed and the knowledge I gained interning with G7 Renewable Energies exceeded my expectations. As a finance student, I knew accounting and the development of financial projections. The Clean Energy field was completely unfamiliar to me, although the energy industry has been a subject I wanted to learn about for some time before coming to G7. Following the closing of my time with G7, I am now comfortable explaining to someone, who is unacquainted with the process of developing clean energy projects, the mechanics of producing a proposal in response to a request for proposal. Correspondingly, if I ever had a particularly challenging task, the G7 team was always there to support me. In summation, my experience with G7 was impactful enough to influence me to pursue a career in the energy industry.”

Milena Lazard

Within the scope of my civil engineering studies in France, I had to do an internship of 12 weeks in a foreign country. Thank to Nicolas and Killian, I had the opportunity to be an engineering intern of G7 Renewable Energies.

This three-month internship has been a fully enjoyed experience. G7 team has allowed me to gain lot of knowledge about wind farm development. This friendly and very professional team has not let me be a simple intern; I have been involved in every aspect of their work.
They have trusted in my work and let me discover each step of wind project development. When I was confused about one aspect, they were here to explain me all detail I needed to get my work successful.

Most of the time, I was working by myself, they were just here to give me advises and I felt like a member of the team. Finally, I learned all aspects, which have to be taken into account to get the wind farm operational. During this internship, I also discovered a new country, a new way of living and I improved my English. This professional experience is, for the time being, the most amazing period of my life. I feel lucky I had this opportunity.

I would like to thank all the members of G7 Renewable Energies!
