Summary: This study examines the environmental and comfort value of renewable energy sources, and introduces their economic value. The results show that in Hungary, the value of environmentally-friendly nature exceeds the convenience factor. Additionally, there is a strong dependency on firewood and natural gas among the Hungarian population. Social capital supply, income level, access to information, and environmental awareness in Hungary are highly correlated.

Summary: This study explores the impact of pricing strategies on cleaner residential heating in China and finds that cost-plus pricing is theoretically the most favorable approach but faces implementation challenges. As an alternative, a modified marginal-cost pricing strategy is proposed, which achieves similar emission reductions with higher operability and robustness.

Summary: Accurate short-term heat load prediction values of different buildings in a residential district are crucial for optimal control of the heat network. This study introduces building ontology parameters and utilizes the Lasso method to analyze and select the influencing factors of heat load. A hybrid short-term heat load prediction model, combining the adaptive T-distributed Satin Bowerbird algorithm with the convolutional neural network, is proposed. The results demonstrate that the introduction of building ontology parameters significantly improves the prediction accuracy of future heat load.

Summary: This paper explores the cognitive process of consumer decision-making based on the theory of bounded rationality, analyzes how product shape affects consumption decision-making using eye-tracking technology, and further explores the design principle of product form. The results demonstrate that users' perceptual cognition has a driving effect on consumption behavior, product form, as a key factor affecting users' perceptual cognition, influences consumer decision-making by influencing the degree of approach motivation, and the principles of product form design can be more consistent with user image preferences by establishing the mapping relationship between product form elements and user images. This study provides useful suggestions for how to increase the purchase behavior of users from the perspective of bounded rationality.

Summary: This paper examines the impact of real-time pricing and load automation on residential distribution systems. The study finds that implementing real-time pricing can result in an aggregate welfare gain of 39 USD per customer and year. However, it also notes that RTP and load automation may significantly increase peak system load. Introducing a market-based demand management system can further enhance welfare gains and reduce grid investment.

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: Russia's weaponization of gas supplies shook the energy security of Central and Eastern Europe in 2022. The region responded by increasing alternative energy supplies and developing new gas supply routes. Renewable energy, nuclear energy, and hydrogen play important roles in the long-term. Mitigating the impact of this shock requires the EU to prioritize the integrity of its energy market.

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.

Summary: This study estimates the willingness to pay of Indian urban consumers for a continuous supply of electricity using contingent valuation method. The findings show that the amount consumers are willing to pay depends on the duration of power outages, with households preferring shorter outages. Income and environmental attitude also positively influence higher willingness to pay. These insights can inform policymakers in designing more reliable and customer-centric energy generation and distribution models.

Summary: The study finds that oil price shocks have a negative impact on Africa's energy transition, particularly in rural areas and net crude oil exporting countries. However, oil price shocks cannot explain the urban-rural differences in clean energy access. Therefore, increasing investment in clean energy and technologies in rural areas is necessary to enhance the resilience of the energy sector to oil price shocks.

Summary: The Renewable Energy Certificate (REC) is considered an innovative technology for building a green society. 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.
