Summary: This study examines the socioeconomic factors influencing energy poverty in clean cooking in Bangladesh. It analyzes household characteristics that drive the choice of cleaner cook stoves and cooking fuels among different population segments. The findings reveal that houses with better ventilation tend to use less clean fuels and more primitive stoves. Renters, on the other hand, use cleaner fuels and technologies. Female or older-headed households have lower adoption rates of cleaner cooking solutions. Household wealth positively correlates with the choice of cleaner cooking options. Education and electricity access do not necessarily lead to higher adoption of cleaner cooking. Urban areas, particularly the capital city, show higher usage of cleaner cooking solutions. The study recommends increased distribution of cleaner fuels and stoves in rural regions and among lower income communities to achieve the national clean cooking target.

Summary: In this study, we investigate the lower thermal conductivity of beta-Ga2O3 thin films grown by MBE. We compare experimental results with numerical predictions and find that the presence of boundary scattering and defects significantly affect the thermal conductivity of the thin films. By considering various types of defects in the calculations, we identify that crystals with gallium vacancies and stacking faults exhibit thermal conductivities closer to the experimental values. These findings provide insights for improving the thermal conductivity of MBE-grown samples.

Summary: This paper aims to analyze the energy transition pathway for a fossil fuel rich developing country, taking into consideration national and international oil availability. The results indicate that without taking action, energy scarcity is inevitable by 2040, leading to economic decline. However, the increasing use of fossil fuels can be partially reduced through policies promoting energy efficiency and renewable energy. Nonetheless, it is crucial to implement ambitious policies in the short term to mitigate the effects of replacing oil as an energy and income source.

Summary: This research focuses on the development of biogas sector in Colombia, a developing country. The study finds that Colombian research mostly concentrates on agricultural waste substrates, inocula, and co-digestion, while full-scale digesters' performance research is lacking. A survey reveals that 79% of the installed digesters in Colombia are psychrophilic low-cost tubular digesters. The existing regulations for biogas in Colombia are not suitable for low-cost digesters and are borrowed from developed countries, disregarding the national context. The research presents five case studies analyzing the barriers and opportunities for AD technology, driven slowly by national networks comprising farmers, NGOs, and academia.

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.

Summary: This paper investigates China's energy trade stability using a survival analysis approach. It finds that the energy trade linkages between China and 153 other countries are complex and unstable, with short periods of trade with many countries. Geopolitically risky regions, such as the Middle East and Africa, have the lowest trade stability. Climate risks have significant effects on energy trade stability. The paper proposes several policy options to improve energy trade stability in China, with special attention to increasing global climate risks.

This study investigates the impact of REC purchases on stock return and volume in Taiwan between 2017 and 2021. The findings suggest that REC purchases have a positive effect on stock returns of manufacturing firms but not service firms. The frequency of REC purchases is also an important factor in the relationship between REC purchase and firm value. Additionally, the study reveals that public attention to environmental pollution plays a crucial role in positive stock returns and volume, while ESG disclosure is negatively associated with returns and volume.

Summary: This paper addresses the challenges of governing energy procurement from a mix of non-hydropower renewable energy sources supplied by independent producers. Building on political economy analysis and five case studies of independent producer projects from Ethiopia, it seeks to understand the root causes of the protracted delays and limited extent of procurement by independent producers. The key contestations lie in managing long term contracts, risk, uncertainty and in developing the institutional and human capacity to transition.
