Update of the review: Cultivation of energy crops in Poland against socio-demographic factors

Abstract

The article presents some of the socio-demographic factors conditioning the production of biomass in Poland. It considers urban-rural and rural gminas that grew energy crops for biomass production in the years 2007-2009 (836 gminas in 2007, 756 in 2008 and 618 in 2009). The article tries to answer the question whether there is a relation between the age of the inhabitants, their opinion on Poland's accession to the European Union and the education level of the local authorities and the area of energy crops in a given gmina. The research uses the correlation coefficient and the analysis of segmented regression.
