Abstract This study investigates the effects of renewable energy determinants on various renewable energy resources. The empirical results are based on data from 31 mainly Asia-Pacific countries observed from 2000 to 2018. Different diagnostic tests indicate the existence of spatial effects in the renewable energy model. The spatial Durbin model with the time-period and spatial fixed effects was selected for analysis. Scrutinizing empirical studies suggest a lack of theoretical consensus on how renewable energy determinants work. By examining how RD however, such effects are incremental for solar, wind, bioenergy, and geothermal energy resources. In an environment with a low level of R&D, financial development has positive effects on hydropower generation and negative impacts on other renewable energy types. However, the expansion of R&D expands reverses such effects gradually. The different results are obtained for different countries at different levels of R&D. Furthermore, trade openness has been a positive factor in the development of hydropower, solar and geothermal energy resources. The results also revealed the negative (positive) impacts of GDP per capita in neighboring countries with a higher (lower) level of R&D on the development of renewable energy of the origin country.
