Abstract

The utilization of renewable energy sources (RES) by the Bulgarian households is studied in this article. A representative study of the Bulgarian population results in hypotheses, investigating the relation between socio-demographic issues and the use of alternative energy sources. The dependence of investments in green energy on key factors such as income and electricity costs was estimated qualitatively by means of statistical methods. An estimation was made of RES investments, recommending to use the latest energy technologies in households in order to meet the national target of 16% share of RES in gross final consumption of energy, as set out in Directive 2009/28/ЕC of the European Parliament and of the Council of 23 April 2009.
