Marc-Joel Fortelny, M.Sc., was born in 1986 in Vienna. During his school days he soon explored various sciences. Ultimately he chose economics at the University of Vienna as his most favored specialization with a focus on Macroeconomics, Public Utility Management and International Management - the "Master of Science" was completed in 2013. From the age of 16 to 24, several internships and freelancer projects in the energy industry provided the necessary experience for career and research. Therefore the topic of this book is inspired and based upon insights into the energy environment.
