Summary: The presence of prosumers with distributed renewable energy is considered effective for enhancing the resilience of the power sector. The current transmission charge, designed to recover transmission investments and routine costs, may shift costs to traditional consumers if more consumers become prosumers, leading to a death spiral. This study examines the impact of prosumers on transmission charge and market outcomes, considering their optimization problem. The findings refute the belief that the transmission charge necessarily increases with the proportion of prosumers in the market, as the bulk power market can benefit from lower power prices due to prosumers' renewable production with low marginal costs, while strategic prosumers may cause the transmission charge to increase by reducing procurement from the bulk energy market.

Summary: China has been advocating and developing renewable electricity to protect the environment and achieve sustainable development. This study investigates the influencing factors of non-renewable and renewable electricity production in China and compares them. The empirical results show that economic growth and electricity production capacity have a long-term relationship with renewable and non-renewable electricity production, while aging only has a long-term relationship with renewable electricity production. Furthermore, a short-term causal relationship exists between economic growth, aging, electricity production capacity, and renewable and non-renewable electricity production.

Summary: This paper introduces a stochastic planning algorithm for the operation of a multi-microgrid (MMG) in an electricity market considering the integration of stochastic renewable energy resources (RERs). The algorithm investigates optimal operation of resources and energy storage by forecasting various uncertainties and using Cournot equilibrium and game theory to model the interactions between the MMG and electricity market. The proposed algorithm is shown to result in above 8% cost reduction in the MMG, highlighting the importance of modeling the interaction between MMG and electricity market under high integration of uncertain RERs.

Summary: Ultra-high voltage direct current (UHVDC) transmission enables efficient large-scale long-distance delivery of renewable energy, but the construction of its infrastructure consumes significant amounts of material and energy. The carbon tradeoffs are often ignored, hindering a comprehensive evaluation of the climate benefits. By collecting field construction data from fifteen 500 kV transmission projects and applying a Life Cycle Assessment framework, this study estimates the infrastructure-induced emissions of nine recently constructed UHVDC projects in China to be 16.7 Mt CO2, which is negligible compared to the annual reduction of 305.2 Mt CO2 contributed by these projects delivering renewable electricity at full load over a 40-year service lifetime. The tradeoff results may change with advancements in energy storage technology or CCUS application.

Summary: Growth in wind and solar energy since 2008 has had a limited impact on reducing average annual wholesale electricity prices in the United States, with the decline in natural gas prices playing a larger role. Recent retirements of thermal power plants in the U.S. are primarily due to low natural gas prices, rather than the growth of wind and solar energy.

Summary: The value of electricity generated from wind and solar sources decreases as supply increases, varying over time and across regions. Strategies to mitigate this value decline need to be carefully targeted, with factors like output profile, transmission congestion, and curtailment influencing the value. In regions where wind or solar contribute approximately 20% of electricity generation, their value can be 30% to 40% lower than the regional average value of a flat output profile.

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.
