The effect of residential solar on energy insecurity among low- to moderate-income households

Abstract

Each year, millions of Americans experience energy insecurity, or the inability to afford enough energy to meet their basic needs. This study evaluates whether residential rooftop solar can serve as a preventative solution to energy insecurity among low- to moderate-income households. Using a national, matched sample of solar and non-solar households based on detailed and address-specific data, we find 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. Energy insecurity is a major concern in the USA, but rooftop solar may be an effective tool for reducing this insecurity of vulnerable households. New research finds that rooftop solar leads to a large reduction in energy insecurity, particularly among low- to moderate-income households in the country.
