Abstract. This study examines the causal relationship between economic growth and renewable energy consumption using data for 28 countries of European Union, taken from Eurostat database for years from 1995 to 2015. In addition, motivated by EU Directive 2009/28/EC, the tendency of the share of renewable energy consumption into the final energy consumption is analysed. Various panel data techniques implemented in EViews are used. The empirical results suggest a positive impact of renewable energy consumption on economic growth, and emphasize bidirectional or unidirectional Granger causalities between the two macroeconomic indicators, for each country in the panel. These results justify the political decisions of EU concerning the necessity of increasing the renewable energy consumption, and prove that this type of energy consumption has a strong positive impact on economic growth. Thus, the inclusion of such policies in future EU and national strategies is further motivated. Finally, by means of linear regression, an increasing trend was found for the ratio between renewable energy consumption and final energy consumption for all but one of the EU countries.

This study analyses the relationship between per capita greenhouse gas (GHG) emissions, gross domestic product, gross inland energy consumption, and renewable energy consumption for a panel of 28 countries of European Union in the period 1990–2016. Two theoretical models, a quadratic and a cubic one, are used to estimate the shape of the environmental curve and to test the Kuznets hypothesis. The panel cointegration approach proved the existence of long-run equilibrium relations among the four macroeconomic indicators. Empirical estimations, using panel data techniques, as well as heterogeneous regression for each individual country in the panel, show non-conclusive evidence for the environmental Kuznets curve (EKC) hypothesis. The least square estimates, with the variables in log per capita form, reveal that the inverted U-shaped EKC hypothesis is verified for the panel and for 17 of the 28 EU countries. Estimates of the cubic model show that the environmental curve has an inverted N-shaped form. These results do not hold when the values are in non-logarithmic form. In addition, the estimations for all models show that an increase of gross energy consumption leads to an increase of GHGs, while an increase of renewable energy consumption leads to a reduction in GHG emissions.

European Union Directive 2009/28/EC established that the share of renewable energy in the final energy consumption should reach a target of 20% by 2020 in European Union (EU) countries. This study analyses the tendency of this share using data for EU 28, taken from the Eurostat database for the period 1995-2016. First, after a brief statistical and economic analysis of the three macroeconomic indicators at EU level, five regression models (polynomial, ARIMA) were used to estimate the evolution of the share of renewable energy consumption into the final energy consumption, all of them showing an increasing trend for this indicator. The positive impact of the EU Directive in increasing this share was proved by means of a perturbed regression model. Forecasts of this share for the 2020 horizon were obtained, all showing that the EU target is yet to be reached. Secondly, four groups of EU-countries were considered, according to the final energy consumption. Empirical estimations of renewable energy share into the final energy consumption showed increasing trend for all groups, while providing forecasts quite different from the EU ones. Also, economic interpretations of the results are performed.

This paper analyzes the impact of the COVID-19 pandemic on economic growth and electricity consumption and investigates the hypothesis of the influence of this consumption on the gross domestic product (GDP) for Romania. Using time series on monthly electricity consumption and quarterly GDP and a multi-linear regression model, we performed an analysis of the evolution of these indicators for 2007–2020, a comparison between their behavior during the financial crisis vs. COVID-19 crisis, and empirically explore the relationships between GDP and electricity consumption or some of its components. The results of the analysis confirm that the shock of declining activity due to the COVID-19 pandemic had a severe negative impact on electric energy consumption and GDP in the first half of 2020, followed by a slight recovery. By using a linear regression model, long-term relationships between GDP and domestic and non-household electricity consumptions were found. The empirically estimated elasticity coefficients confirm the more important impact of non-household electricity consumption on GDP compared to the one of domestic electricity consumption. In the context of the COVID-19 pandemic, the results of the study could be useful for optimizing energy and economic growth policies at the national and European levels.

This study analyzes the evolution and trends of the share of remittances in gross domestic product (GDP) and the influence of migration on remittances in Romania. The analysis on data from Eurostat over 2008–2017 has three components: a statistical analysis, an estimation of evolution of indicators, and an estimation of impact of migration on remittances, using polynomial-time regression and difference equation models, respectively. The results showed that GDP and GDP/capita had a permanent increase, meaning an improvement in the standard of living in Romania, while the other indicators had an evolution with a period of sharp decline triggered by the global crisis, followed by a slow growth. We may conclude that the remittances represented and still represent a relatively stable financial resource for Romania as for the other emerging countries in Europe, affecting in a positive way the standard of living of the citizens, although their value has a tendency to decrease. At the same time, the negative effects of remittances, dependence on money received from migrants and the exodus of “brains” and skilled workers, must be considered, implying the necessity of government policies for a better use of remittances, i.e., mainly for investments and less for consumption.
