Determinants of Households' Investment in Energy Efficiency and Renewables

Many studies on household energy efficiency investments suggest that a wide range of seemingly profitable investments are not taken up. This paper provides novel evidence on the main factors behind consumer choices using the OECD Survey on Household Environmental Behaviour and Attitudes. The empirical analysis is based on the estimation of binary logit regression models. Empirical results suggest that households’ propensity to invest in clean energy technologies depends mainly on home ownership, income, social context and households’ information. Indeed, home owners and high-income households are more likely to invest than renters and low-income households. On the other hand, social context, such as membership in an environmental non-governmental organisation, and households’ knowledge about their energy spending and use may play a relevant role in technology adoption.
