Development of Energy from Renewable Sources and Energy Intensity of the Economies of Central European Countries in the Context of the Europe 2020 Strategy

The hypothesis resulting from Europe 2020 Strategy was examined in the present article. It concerns the reduction of greenhouse gas emissions through decrease of energy consumption of economies and the increase of share of renewable energy sources. The econometric models were used to calculate the forecast of greenhouse gas emissions for 2020. Due to the fact that explanatory variables of models reveal the collinearity, the ridge regression was used to estimate parameters. However, the achieved results indicate to too low target definition. Through the statistic and econometric methods it will be possible to do it more thoroughly and as a result it will enable better control over the realization.
