Development of bioenergy will be a key component for meeting increasing energy demands while mitigating global warming. With the intent of identifying current topics of major interest and development of research directions in the field of bioenergy under climate change, we conducted a bibliometric analysis and network analysis from a country perspective based on 3050 articles published since 1999 derived from the Scopus database. The results indicated that USA, UK, and Germany led other countries in terms of number of publications (1006, 366, and 280 articles, respectively) and h-index (greater than 50) in this research area. The USA has also produced a large number of articles in highly respected journals. Compared with developed countries, some developing countries (e.g., China, India, and Brazil) have a larger proportion of publications which are cited less than 10 times and researchers who have academic age of 1 year. The number of publications dealing with some of these research topics coming from developing countries has lagged behind the number of similar publications coming from developed countries. In spite of this, research on sustainable energy systems is still needed for developing countries to further establish feasible systems that can effectively promote global economic development and strengthen climate change mitigation efforts.
