The purpose of this study is to investigate the relationship between renewable energy and economic growth which is determined by the gross domestic product per capita regarding some of the Mediterranean countries. This study uses data from some Mediterranean countries with medium to high energy consumption levels in 1990–2015 (France, Italy, and Turkey) to ascertain and analyze the multiple effects of renewable energy consumption on economic process. The applied math analysis relies on descriptive statistics, cluster analysis, and divulges that all the variables area unit are related; this means, on the long term, a correlation between the dependent variable quantity of gross domestic product and the independents variables of renewable energy consumption and energy consumption. Moreover, the results show that there's a better correlation between RES’ consumption and the economic growth of some countries that has an upper gross domestic product than with those of lower GDP. The obtained results area unit is consistent with different papers reviewed during this study. Analysis results show the long run linear impact of energy consumption on economic process.
