  abstract  = {This paper analyses international cooperation in alternative energy production research and development. Therefore, patents of the technological domain, registered at the European Patent Office from 1997 until 2016, are analysed. International cooperation is considered when patents involve co-assignment or co-inventorship comprising two or more different countries. Generally, international R\&D cooperation tends to be increasing over time in alternative energy production. In total, 2234 co-patents from 87 countries are identified. Through social network analysis the cooperative relationships between countries are examined. The most significant states of the network are the United States of America and Germany. Innovative clusters and strong partnerships are identified. Alternative energy technologies that involve international cooperation most extensively are harnessing energy from manmade waste, solar energy and bio-fuels. The paper clarifies which countries are cooperating with each other for what purpose. The findings can be used for establishing R\&D strategies in the domain of alternative energy production.},
