Summary: To achieve carbon neutrality and sustainable development goals, the transition to renewable energy is occurring in the energy system, with hydropower being a significant form. However, hydropower is vulnerable to climate anomalies, such as droughts, resulting in energy droughts. This study analyzes the spatiotemporal characteristics of energy droughts over the Yangtze River basin and finds that there are about 10 energy droughts per year during 2007-2021, with a mean duration of 7 days/event and a 26% reduction in daily developed hydropower potential (DHP). The occurrence of energy droughts is influenced by El Niño-Southern Oscillation (ENSO), and the propagation from meteorological droughts to energy droughts takes several days.

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.
