Macroeconomic Indicators Used to Study the Efficiency of Investments in Renewable Energy Field

This paper aims to analyze the main indicators used to express the efficiency of renewable energy investments at macroeconomic level. Based on three econometric models, we present the calculation method of these indicators, along with interpretation. In the study are included countries with very high and high human development, member states of the European Union. Results indicate that all countries have a good economic efficiency of investments in renewable energy, but low social efficiency. As for the environmental efficiency of renewable investments, the findings reveal that only six European countries manage to direct their efforts to mitigate carbon dioxide emissions and in this way to have a high environmental efficiency of investments.
