This study evaluates whether residential rooftop solar can serve as a preventative solution to energy insecurity among low- to moderate-income households.
We found that solar leads to large, robust and salient reductions in five indicators of energy insecurity.
Moreover, the benefits of solar ‘spill over’ to improve a household’s ability to pay other energy bills.
The results suggest that rooftop solar may be an effective tool for policymakers who seek to reduce energy insecurity.
