Green Energy Summer School (GESS)

Summer with Renewable Energy and Energy Efficiency

12 - 30 August 2019 in Berlin

The Renewables Academy (RENAC) provides with its Green Energy Summer School (GESS) a unique opportunity to get an exceptional insight into renewable energy sources, the various technologies of harnessing them and how to save the energy captured through energy efficiency. The three-week programme takes place in the summer of each year in Berlin, Germany. Each week offers a different theme of renewable energy or energy efficiency, designed for different target groups, taking into consideration their knowledge on the subject and their background. This year we selected the following themes for you and hope you will join our Green Energy Summer School:

All these are achieved through a blend of up to date theoretical lectures, state of the art practical exercises and field excursions accompanied by a lot of fun and international networking. The "Green Energy Summer School" serves as a platform to study in a team with professionals from many different countries while bringing renewable energy and / or energy efficiency know-how to perfection.
