Summary: The article proposes a new method for attributing changes in aggregate intensity index, which satisfies factor reversal test, time reversal test, and reciprocal attribution rate test by transforming intensity into a multiplicative formula that does not depend on the denominator weight. The proposed method is verified and compared with existing methods through numerical illustration, sensitivity analysis, and actual case studies, demonstrating its applicability and economic significance.

Summary: As the share of renewable energy increases in the energy-mix, tracking the dynamics and determinants of energy intensity (EI) is a crucial issue in energy economics related to power resilience. A novel generalized Divisia index (GDI) model combined with the Tapio index is proposed to decompose the intensity factors, with a case study of China's power sector from 2000 to 2020. The results show that although energy efficiency has improved during the period of 2000-2020, the complexity of reducing EI has increased from 2006-2010 to 2016-2020, and provincial EI exhibits a distribution trend of high in the north and low in the south, high in the east and low in the west. The decomposition results indicate that energy consumption is the main factor contributing to EI increase, while energy structure and technology are the major forces contributing to EI mitigation. Most provinces show a decoupling status between power output/energy consumption and EI, but the decoupling situation is unstable and the difficulty of decoupling has increased since 2016-2020.

Summary: This study investigates the driving forces behind energy intensity changes in Chinese cities using production-theoretical decomposition analysis. The results suggest that technological change and capital-energy substitutions are the main factors contributing to the decrease in energy intensity, while technical efficiency has a moderate impact on the increase in energy intensity. Different cities show significant variations in energy intensity changes, with double and triple drivers prevalent. The study further categorizes cities based on differences in energy intensity and energy efficiency changes, revealing key measures to reduce energy intensity and potential misjudgment by policymakers regarding energy efficiency performance.

Summary: This paper decomposes the electricity intensity in the European Union from 1995 to 2019 into structure, efficiency, and electrification components, showing that the impact of efficiency component is greater than expected and requires continued technological innovation. The electrification component contributes to the increase in electricity intensity, while the structural element has a minor influence. Country-specific efficiency policies may be considered given the distinct values and particularities of each EU-28 country.

Summary: Energy consumption is crucial for economic development and carbon emissions. This study develops a new method to analyze the progress of carbon intensity change in 79 economies from 2007 to 2014. The findings show that developing countries with high energy consumption are more energy efficient, while high energy consumption developed countries and low energy consumption developing countries have made significant technological progress. The decrease in global carbon intensity is mainly due to the reduced potential energy intensity effect, while energy technology and efficiency gaps have contributed to an increase in carbon intensity.

Summary: To achieve sustainable development goals, China has increased its target of reducing carbon intensity and made digitalization a crucial support for sustainable development. However, the impact of digitalization on carbon intensity reduction is still unclear. This study evaluates the digitalization level of 30 provincial regions in China and examines the spatial spillover effects of carbon intensity and the role of digital infrastructure and inputs in carbon intensity reduction. The findings demonstrate that digitalization drives sustainable development.

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.
