About this event

Domestic renewable energy systems have enjoyed considerable government support in Europe and the United States. Yet despite their ubiquity there is a gap in evaluating their effectiveness. We examine the impact of the 2017 Home Energy Loan & Grant Scheme (HELS) in Scotland using administrative data on the universe of domestic solar photovoltaic installations in the United Kingdom since 2008. Exploiting the devolved nature of renewable energy support policy in the UK we implement a matching strategy between Scottish and English locales to provide a causal assessment of the scheme's effectiveness. Our findings are three-fold. First the HELS increased domestic solar photovoltaic installations. Second the HELS' funding ceiling biased installation sizes downward. Third a complementary distributional analysis reveals that the vast majority of the HELS benefits accrued to the top three deciles by house value.


Participants are expected to adhere to the Events Code of Conduct.
