Summary: Transitioning towards low-carbon energy systems requires increasing residential Photovoltaic (PV) contribution through PV self-consumption, which can be supported by adopting PV self-consumption policies and incorporating batteries. However, it is crucial to assess and mitigate the technical impacts of PV policies on distribution networks. Implementing a two-stage planning framework that optimizes PV and battery sizes, and evaluates impacts on distribution networks through Monte-Carlo simulations, is essential for achieving sustainable energy goals.

Summary: This paper examines the impact of tax incentives in the form of bonus depreciation on investment quality. Through analyzing the expiration of tax incentives in eastern Germany and a representative panel of West German establishments, we find that bonus depreciation significantly reduces investment quality. In the short run, the average quality of investments, measured by the responsiveness of future revenue and other proxies for cash flow to current investment, decreases by 15.2-23.8%, while in the long run, it decreases by 31.8-41.4%. Our research suggests that this negative effect of tax subsidies is more pronounced in regions with higher tax rates, during periods of high unemployment, and for large or low-productivity establishments. Overall, while prior literature has shown that tax incentives increase investment quantity, tax incentives such as bonus depreciation substantially reduce the quality of investments.

Summary: China aims to peak carbon dioxide emissions by 2030 and achieve carbon neutrality by 2060. Shore power, also known as cold ironing, is a commonly-used technology to reduce emissions from berthing vessels in port cities. This paper investigates the optimal capacity of shore power berths (SPBs) by considering the choice behaviors of vessels with power receiving facilities (VWs) on SPBs and traditional berths (TBs). The government adopts environmental incentive (EI) and infrastructure subsidy (IS) mechanisms to promote capacity investment in SPBs and reduce total emissions, with IS being the most effective.

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.

Summary: Economic costs are a major political obstacle to investing in climate change mitigation and adaptation measures. The method of financing plays a crucial role in determining public opposition to government green investments, with debt financing being less opposed than broad-based taxes. This study suggests that credit market tools, such as green bonds and debt for climate swaps, can be politically efficient in increasing support for green financing. Carbon taxes and wealth taxes are found to be the most preferred options.
