Consumption of renewable energy sources results in minimal production of greenhouse gases. However, the key issue of the environmentally efficient use of renewable energy sources remains a key question.
The main aim of this article was to assess whether the production of energy from renewable energy sources is environmentally efficient in the region of four selected European countries. Regarding this objective, the following European Union countries were selected: Germany, Austria, Poland and the Czech Republic.
In order to achieve the main research goal, the regression analysis method for several variables was used. The results of the analysis suggested that the growth of consumption of renewable energy sources and biofuels by one thousand tons of oil equivalent, the volume of emissions from all sectors will increase by 0.0048 thousand tons (4.8 tons) on average .The system of emission allowances was rather environmentally inefficient at the low price of allowances and in the monitore
