An improvement in the standard of living and a fast civilization progress in the 21 st century result in a constantly growing demand for energy. The share of renewable energy sources (RES) in the total energy generation and consumption is increasing due to the limited nature of fossil fuels and their adverse impact on the environment. The paper examines the correlation between selected socioeconomic variables and the number of RES and evaluates the potential impact of these factors on introduction of RES in all districts (powiat – second tier administrative unit) of the Świętokrzyskie Voivodeship (Poland). The following socioeconomic variables were used: surface area of agricultural land, surface area of land under surface flowing water, surface area of wasteland, population density, unemployment rate, number of unemployed persons registered for over a year, total EU funds acquired, per capita income, and EU funds acquired per capita. Moreover, the paper presents the current use and methods of acquiring RES, split into types in the studied area. The research method was the Spearman’s rank correlation. The study resulted in a determination of the strength and direction of correlation between the tested variables and in an attempt to answer the question: what variables, if any, affect the introduction of RES in the studied area?
