The determinants of renewable energy usage intentions using theory of planned behaviour approach.

Public acceptance is a crucial factor for the development of renewable energy. Therefore, the enhancement of intention to use renewable energy is required in seeking promotion of renewable energy. Thus, the aim of this study is implementing the theory of planned behaviour in order to analyse the main determinants of intention behind using the renewable energy in Lithuania, as one of the Central and Eastern European countries (CEE). The results show that respondents mostly prefer to use solar energy. Meanwhile the fewest citizens intended to use biomass and hydro energy. Referring to the results of regression analysis, the level of development of renewable energy and financial abilities influenced the intention to use renewable energy the most. Subjective norms also significantly and positively determined the intention to use renewable energy. Meanwhile attitudes to renewable energy had no effect on intention to use renewable energy. Only interaction of environmental concern and attitude to renewable energy significantly contributes to intention to use renewable energy. Therefore, this study contributes to the overall discussion on renewable energy usage and its proliferation in the European Union, specifically in the CEE region. • Applying the theory of planned behaviour evaluation of determinants of intention to use RES. • Respondents mostly prefer to use solar energy and the least intended to use biomass. • The level of development of RES and financial abilities influenced the most the intention to use RES. • Subjective norms positively determined the intention to use renewable energy. • Interaction of environmental concern and attitude contributes to intention to use RES.
