Summary: Household electricity consumption levels and timing are significantly influenced by household characteristics such as dwelling type, heating technology, use of electric vehicles, and the number and age of household members. Flat rate pricing in Denmark currently shows limited cross-subsidies between residential customer groups, indicating that introducing real-time pricing for Danish residential customers could improve economic efficiency without significant redistribution concerns.

Summary: We use panel data to analyze the demand for residential rooftop solar and the impact of net energy metering compensation. Our findings indicate that rooftop solar demand is highly price elastic and income elastic. We also find that there is a strong substitution effect between rooftop solar and utility-provided electricity due to poor residential rate design. Net energy metering has a significant positive impact on the demand for residential rooftop solar, leading to an increase in demand and bypassing of utility-supplied electricity.

Summary: This paper examines the response of urban and rural residents in a China's northwestern province to temperature changes in terms of electricity consumption, and uncovers its impact on daily electricity consumption inequality between these two groups. The study findings show that the urban response function exhibits a U-shaped distribution, while that of rural residents demonstrates a fluctuating upward trend. When the daily mean temperature falls below 24°C, the gap between urban and rural electricity consumption increases. During the Spring Festival, the negative effects of extremely low temperatures will be reduced, while at the end of October, they will be increased.

Summary: Accurate forecasting of time-varying electricity demands is crucial in residential buildings, as it impacts the load curve in the utility grid. This study in Kuala Lumpur, Malaysia, conducted field measurements in 19 dwellings to analyze electricity usage and indoor thermal environment. Variations in total electricity consumption were observed among different income groups, while AC electricity consumption remained consistent, possibly due to usage patterns during sleeping hours.

Summary: This paper investigates the relationship between electricity efficiency and residential electricity consumption and finds a rebound effect, where a portion of energy savings from efficiency improvement is offset by households' behavior adjustments. The study also reveals that residential income, population density, and temperature deviation play vital roles in electricity consumption, while household size significantly affects the magnitude of the rebound effect.

Summary: Analyzing residential load profiles and usage patterns is crucial for demand-side management and energy-saving strategies. This paper presents detailed research on electricity consumption and profiles in Dubai based on dwellings' characteristics and smart meter data. The households were grouped using K-Means clustering, and consumption patterns were organized and identified. Classification algorithms were applied to predict household patterns based on characteristics. The analysis revealed peak demand variations and identified key characteristics driving electricity demand patterns.

Summary: This study investigates the impact of energy policies on the energy performance of residential properties in nineteen districts of Portugal from 2014 to 2021. The empirical results show that income per capita has a negative effect on highly energy-efficient properties and a positive effect on properties with low energy efficiency. Codes and standards energy policies have a positive effect on both high and low energy-efficient properties. Fiscal and financial incentive policies have different effects on properties with different energy efficiency levels. Information and education policies have a positive effect on both high and low energy-efficient properties. Consumer credit per capita has different effects on properties with different energy efficiency levels.

Summary: In India, four-wheel battery-electric vehicles have higher greenhouse gas and sulfur dioxide emissions compared to other conventional or alternative vehicles. Electrified buses and three-wheelers are the best strategies for reducing greenhouse gas emissions, but they are also worse in terms of sulfur dioxide emissions. In one state, electrified two-wheelers have lower sulfur dioxide emissions than gasoline vehicles.

Summary: The current policies for decarbonizing existing buildings through the circular economy principles need practical measures tailored to local conditions for increased effectiveness. The lack of standard practices for assessing buildings' refurbishment strategies towards energy efficiency and circular economy principles is a challenge. To address this issue, this paper proposes a new framework for refurbishing circular buildings based on circular procurement and a lifecycle perspective. The framework fosters dialogue between local authorities and private stakeholders and incorporates building mapping, selective disassembly, (re)design, and (re)build practices, providing opportunities for policy-based incentives. Applying the framework in Portugal demonstrates its potential in identifying critical moments in the refurbishment process to implement new circular economy policy actions at the building level, aligning with local construction permitting procedures and utilizing resources and incentives offered by the local administration, such as tax incentives.

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: 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.

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.
