Summary: States in the US have varying efforts to address climate change. Strong state climate policies can reduce CO2 emissions without harming the economy, but it's unlikely that these reductions will meet the Paris Climate Accord goals. This study develops an aggregate index of state climate policies and finds that a higher climate policy is associated with a reduction in CO2 emissions, both in the electricity sector and economy-wide.

Summary: Renewable energy quota in China is allocated at provincial level using a zero sum gains data envelopment analysis (ZSG-DEA) model and entropy model, with the rationality evaluated by an environmental Gini coefficient. The allocation results successfully transfer the responsibility of renewable energy quota from western provinces to eastern provinces.

Summary: This paper examines the trade-off between the cost and effectiveness of renewable portfolio standards (RPS) and proposes a coevolution model to explore the impact of incentive mechanisms on RPS. The simulation results show that RPS effectiveness gradually increases with the coevolution of the renewable energy system, while its cost initially increases before later decreasing. However, path-dependence of market players' behavior hinders further improvement in cost-effectiveness.

Summary: A Renewable Portfolio Standard (RPS) is a policy instrument aimed at increasing the production of clean energy technologies by mandating a minimum market share, with its cost-effectiveness depending on the market structure and level of competition. Research shows that deregulated markets minimize subsidy requirements for clean energy technologies with lower penetration rates, while regulated markets do so for higher market share mandates. Identifying a critical market share can help policymakers design more cost-effective RPS mandates in both regulated and deregulated markets.

Summary: This paper identifies the irreplaceable role of users in renewable energy consumption and proposes a method to guide users to optimize their electricity consumption behavior by constructing a RPS assessment value transmission model and optimizing the RPS value allocation mode. Simulation analysis shows that the user-side RE contribution identification method effectively determines the user's contribution to RE consumption, and the RPS value allocation mode can optimize users' power consumption behavior and promote RE consumption.

Summary: The study found that lower RPS coordination among regions results in increased U.S. natural gas exports to Canada, increased U.S. natural gas prices, and decreased net U.S. natural gas exports to Mexico in the long term. Moreover, international coordination of RPS in the electricity sector leads to smaller price discrepancies in the U.S. natural gas market when compared to the reference scenario.

Summary: Renewable energy transitions at global and national scales are slower than expected, leading regional and localized entities to take action themselves. Over 200 communities in the US have pledged to achieve 100% renewable energy, but there are still uncertainties and significant gaps in the plans. A study showed that only 40% of communities had public action plans, indicating shortcomings in energy transition plans even at the community scale.

Summary: This study proposes a simulation model to investigate the complex relationship between China's consumption side renewable portfolio standards (RPS) and domestic nationwide carbon emission trading (CET) scheme. The results show that both mechanisms can facilitate the expansion of renewable electricity, but the quota goals need to be reasonably set, and more demand incentive mechanisms are required for the tradable green certificates (TGC) market.

Summary: Multiple studies have examined the impact of state-level renewable portfolio standards (RPS) on renewable electricity generating capacity and found that the conclusions are not robust. The 2009 American Reinvestment and Recovery Act has had a significant, positive impact on renewable electricity generating capacity. State-level RPS are not sufficient to reduce greenhouse gas emissions from the electricity sector without federal action.

Summary: The commonly held belief that a poorly conditioned covariance matrix affects the sensitivity of mean-variance optimized portfolios is questioned in this research. The inclusion of a budget constraint in the optimization problem challenges this explanation. The empirical analysis shows that the derived bounds for portfolio changes can greatly overstate the actual maximums. These results are explained by the original derivations.

Summary: This paper analytically studies the long-run effects of renewable portfolio standards on electricity prices and finds that the effects depend on the nature of the long-run average cost. The paper also discusses the differences between the long-run effects and the short-run effects, as well as the effects of increasing the stringency of an existing standard versus introducing a new standard.

Summary: This paper proposes a multiobjective equilibrium model to develop an annual power plan for a single province in China. A case study in Guangdong province is conducted to demonstrate the practicality and efficiency of the model, with comparison analysis against the current plan. The study finds that the optimal model can achieve higher proportions of renewable electricity and non-hydro renewable energy consumption, while reducing generation costs and CO2 emissions. In addition, policy suggestions are provided for provincial governments to better implement renewable portfolio standards.

Summary: The COVID-19 pandemic has exacerbated energy insecurity among low-income populations in the United States, particularly increasing the likelihood of energy insecurity among Black and Hispanic households, those with young children, individuals requiring electronic medical devices, or living in inefficient or poor conditions. These conditions exist under normal circumstances, but the pandemic seems to have worsened the overall incidence of energy insecurity.

Summary: Critics argue against government investment in clean energy, claiming that governments should not pick winners, green subsidies promote rent-seeking behavior, and failed companies indicate failed policy. However, these arguments are flawed and should not dictate the direction of energy investment policies.

Summary: This study examines household energy insecurity during the first year of the COVID-19 pandemic in the United States. The researchers find high levels of energy insecurity, particularly during the early months when the economic impact was the greatest. They also identify disparities among different groups, with people of color, those with very low income, young children, individuals relying on electronic medical devices, and those living in inadequate housing conditions being more likely to experience energy insecurity. Furthermore, these groups were more likely to face persistent energy insecurity throughout the first year of the pandemic.

Summary: The study finds that low-income households employ various coping strategies in order to pay their energy bills, some of which pose physical and financial risks. Vulnerable households and those living in deficient housing conditions are more likely to engage in multiple coping strategies. These findings have significant implications for improving public policies.

Summary: Small industrial sources, such as concrete batch plants, contribute to air pollution problems by releasing large amounts of particulate matter (PM). A study on 131 concrete batch plants in Harris County, Texas, revealed that these plants collectively emit significant amounts of primary PM2.5 and PM10, leading to health damages and raising environmental justice concerns. The findings emphasize the need for increased monitoring, emissions reporting, and consideration of cumulative impacts from small pollution sources.
