Abstract
The object of the study is public-private partnership projects in green energy in developing countries. The problematics of the study is based on the intersection of the current problems of improving energy efficiency and environmental friendliness of energy innovations. The problem of analyzing such projects was solved with the following results: The findings of the study indicate the importance of country income as a factor influencing investment in public-private partnership projects in green energy. The analysis indicates the importance of the country's income as a factor influencing the established technological structure of public-private partnership projects in the green energy sector. It is proved that energy efficiency significantly depends on the technological structure of public-private partnership projects in green energy. The obtained results are explained by assuming the dependence of public-private partnership projects in green energy on the income level of the economy, based on Wallis one-way analysis of variance and cross-tabulation. Mann-Whitney U test was used to explain the dependence of energy efficiency on the technological structure of such projects. The particularity of this study is the analysis of the technological structure of public-private partnership projects in green energy, taking into account the specifics of developing countries and the application of their clustering. This research is of practical significance in the possibility of applying the results obtained by the authorities for the creation and implementation of public-private partnership projects in the field of green energy, as well as by energy companies implementing new technologies using water, wind and solar energy.
