The role of renewable energy sources in residential electricity prices: A club convergence analysis across selected European countries

Abstract

ABSTRACT This research analyses the convergence of residential electricity prices in 22 European countries between 1995 and 2019. The findings reveal the existence of two sub-convergent clubs of residential electricity prices. Half of the countries studied belong to the club with higher residential electricity prices, while the other half belong to the lower-price club. Household income increases the probability of belonging to the club of lower residential electricity prices. An increase in heating degree days decreases the probability of belonging to the club of lower residential electricity prices. A similar effect is observed for the price of non-renewable energy sources used in electricity production. Further, although a country’s likelihood of belonging to the club of lower residential electricity prices diminishes with a rise in the share of renewable electricity production, the converse pattern is obtained at the residential level, such that residential renewable electricity share has a beneficial effect. Our findings suggest that households have benefitted in paying lower prices for renewable sourced electricity. Therefore, this research indicates that ongoing clean energy initiatives and the availability of affordable substitutes for conventionally generated electricity are being realized to a certain extent, improving electricity markets for the countries we analysed.
