Summary: Research shows that subsidies for household-level wind and solar PV systems tend to benefit more affluent socioeconomic groups, while payments to community energy projects tend to flow more consistently into areas of higher deprivation, particularly in the case of community solar. This suggests that community energy has successfully brought the benefits of low-carbon technologies to areas of lower income and higher deprivation, providing important lessons for policymakers interested in promoting a just transition.

Summary: This paper investigates the impact of support policies on the invention and diffusion of solar PV technology, and whether this impact is heterogeneous and counteracting, in order to assist policy makers in formulating a better policy mix. The policies examined include Feed-in-tariffs (FITs), Public R&D stock and flow, Environmental tax, and Environmental Policy Stringency Index. Assessing policies on multiple dimensions is crucial as there is a risk that policies may promote one aspect of technological progress, such as invention, but hinder diffusion. The study utilizes a Schumpeterian technological development approach on a panel dataset covering 23 European countries from 2000 to 2019. Two econometric approaches are employed, with a negative binomial regression model used to evaluate inventions and a panel data fixed effect regression used for the diffusion model. The empirical findings suggest that no counteracting policy effects were found.

Summary: Household solid fuel use is detrimental to health and the environment. The Indian government's PMUY subsidy has successfully promoted the adoption of LPG by millions of households. However, there is limited understanding of the decision-making process to reduce solid fuel use after transitioning to cleaner fuels. This study found that factors such as household wealth, social status, education level, and the prevalence of LPG use in the village are positively associated with LPG consumption and the discontinuation of solid fuel use. On the other hand, factors such as distance to LPG refill delivery, household size, and the PMUY subsidy are negatively associated with the share of LPG use.
