Summary: To address climate change and achieve sustainable development, decarbonizing China's electric power system is crucial. This study examines the low-carbon transition and sustainable development of China's power system through 2035. The analysis suggests that rapid electrification will lead to a significant increase in electricity demand, requiring the replacement of coal-fired power generation with renewable energy. Incorporating electricity demand-side management is essential for an effective decarbonization pathway. The results of this study can provide guidance for policy makers in China and other emerging economies.

Summary: Cities are at the forefront of global climate mitigation efforts due to their significant contribution to energy-related CO2 emissions. The 'SolarEV City' concept proposes an integrated system of rooftop photovoltaics and electric vehicles to provide affordable and dispatchable CO2-free electricity to urban dwellers, with potential cost savings and significant reductions in CO2 emissions. Governmental interventions are crucial in enabling the implementation of such systems, highlighting the importance of collaborative efforts among policy makers, communities, industries, and researchers to overcome barriers and promote decarbonization in urban environments.

Summary: Recent research shows that occupancy-based HVAC controls (OBCs) can save energy in commercial buildings, but the adoption of this technology in building energy codes is not widespread. This study evaluates the cost-effectiveness and decarbonization benefits of OBCs and provides guidance for integrating occupancy sensors into building energy code development. The findings reveal that the current cost-effectiveness of OBCs is limited due to the high cost of occupancy sensors, but considering the societal cost of carbon factor can greatly enhance their cost-effectiveness. Furthermore, reducing the cost of occupancy sensors and incorporating OBCs in building energy codes can lead to significant CO2 emissions savings.

Summary: This analysis explores decarbonization opportunities for U.S. refineries and the associated costs. By switching energy sources, implementing carbon capture and storage, and changing feedstock, refineries can reduce CO2 emissions. Only the third option can reduce emissions throughout the entire life cycle of refinery products. Combining all three strategies can achieve negative life-cycle CO2 emissions, with an average cost of $113-$477/MT CO2 or $54-$227/bbl of processed crude, driven by the expensive biocrude feedstock.

Summary: The need for a clean and affordable energy supply is a major challenge of the current century, especially for small islands with limited infrastructure and financing. This study focuses on improving an established energy model framework by adding a tool that estimates the cost of electricity for different technologies and systems. The model is used to predict future energy scenarios for San Pietro island in Sardinia and rank them based on their efforts in achieving an energy transition. The results demonstrate the importance of renewable energy in reducing costs and raise questions about the convenience of large storage infrastructures.

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.
