Book excerpt: The book is a study of the cooperation of Brazil and India on renewable energy. It is based on a research project on the energy sector of both the countries. It discusses the agreements in the energy sector between the two countries and the renewable energy policies developed in four decades. A scientific and technological mapping, a brief study of competitiveness and a primary research were carried out in order to find out the weaknesses and the opportunities for cooperation in renewable energies. This Publication will undoubtedly provoke the reader to reflect on the importance of cooperation given the growing protectionism not only in terms of energy security, but also in terms of investments in new technologies considering energy transition scenario. For Brazil and India, intensifying the dialogue is more than a strategy of visibility and the search for greater space in worldwide geopolitics.
