Understanding the main factors behind the household investments in energy efficiency retrofits (EER) and renewable energy (RE) adoption is essential for designing efficient and effective policies. In the Netherland, a number of factors have been identified as drivers and barriers of EER and RE adoption based on the earlier national household surveys [1]–[3]. However, the results of the regression analyses on the questionnaire survey suffer from high dimensionality (i.e. too many variables) and inability to explain the relationship between variables. To address these shortcomings, we conduct the exploratory factor analysis (FA) to identify the underlying factors behind a number of variables important for EER and EE adoption.
