Through an analysis of U.S.-oriented energy equity literature and recently developed tools and frameworks for decarbonization, this paper provides the first comparison of U.S. national versus subnational perspectives on defining disadvantaged communities, their energy equity concerns, and relevant metrics in the context of decarbonization.

The Minnesota Paradox has been identified in indicators with complex, structural social determinants: income, employment, educational outcomes, incarceration rates, home ownership, and even drowning. In this paper, we ask if similar disparities exist in access to shared infrastructure systems, focusing on the electric system, an essential service delivered by heavily regulated public utilities. We examine disparities in access to electricity service across three dimensions: utility disconnection, service reliability, and availability of the grid to host distributed energy resources. We quantify disparities across Census block groups by leveraging unique, high-resolution datasets that have only recently been made publicly available. We find significant and pervasive evidence of the Minnesota Paradox across utility disconnection and service reliability. Across a battery of regression models, we find that living in neighborhoods with a greater concentration of people of color is associated with a statistically and practically significant difference in the likelihood of disconnection from service due to non-payment and the experience of extended power outages. We also find a positive association between communities with larger populations of people of color and hosting capacity, suggesting a potential opportunity to affirmatively address disparities in energy insecurity in the energy transition. These findings shed light on the pervasive nature of the Minnesota Paradox in the electric system, which underscores the pressing need for policy initiatives to rectify deep-seated inequalities and ensure all communities have equitable access to universal basic utility service and reliable, clean energy.</p></div>","PeriodicalId":35642,"journal":{"name":"Electricity Journal","volume":"37 6","pages":"Article 107423"},"PeriodicalIF":0.0,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141839295","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Kyoto Protocol and the Paris Agreement aimed to address climate change by promoting sustainable clean energy technologies. The UN conference in the United Arab Emirates in December 2023 concluded with an agreement marking the end of the fossil fuel era. All these developments aim to address climate change through the use of clean energy technologies while maintaining economic growth. The connection of climate change with the developing model has gained significant importance on countries’ adjusted plans for climate change. The fossil fuels have a negative impact on economic growth of Greece, implying a continuous dependence from non renewable energy sources and a burden of economic expansion. The reliable estimation of the consequences of climate change on growth, both spatial and temporal, constitutes a decisive parameter for the adjusted plan not only in short term level but also in a long term horizon. Focusing on the improvement of energy efficiency, on the maximization use of renewable energy sources in Greece, on the emphasis given to technologies and fuels storage as well as alternative technologies of energetic and industrial sector, the achievement of energetic and climate transition designed on Greece will be feasible on a long term strategy. The results showed that the growth of renewable energy sources to produce electric energy is necessary for the sustainable growth of Greece. Specifically, the results of ARDL model showed that the renewable energy sources have a positive impact on economic growth in Greece in the long run, and the non-renewable energy sources have a significant effect on economic growth in the short run. These results imply that the aim for investments on renewable energy sources from policy makers should be direct mainly on regions with high levels of carbon dioxide emissions due to lignite combustion.</p></div>","PeriodicalId":35642,"journal":{"name":"Electricity Journal","volume":"37 6","pages":"Article 107421"},"PeriodicalIF":0.0,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S1040619024000563/pdfft?md5=791627ba450b843c861c0ea87aa44c98&pid=1-s2.0-S1040619024000563-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141480494","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the political ecologies of solar power are uneven.

Conversion from overhead to underground systems due to security and climate change factors will increase the risk of FCOs due to site conditions. The failure in collaboration by front-end planning (FEP) teams can increase risk of FCOs due to missing scopes, errors in design, lack of existing field condition evaluation, constraints on the project schedule, or unexpected field conditions, among other causes. This study involved development of a quality control process that enables members of the FEP team to vote their confidence levels about risk control of FCOs before proceeding to final design. The proposed process utilized Analytical Hierarchy Process (AHP) methodologies to distribute the weights of stakeholder votes based on responsibilities for each category of FCOs to obtain an integrated metric of FEP team confidence. Data from an operational electric power utility was used to provide a case scenario approach and to illustrate the method. Three actual projects were analyzed to assess how well the process would have worked for them. The novelty of the proposed model is to enhance the effectiveness of collaborative working relationships across teams during the FEP process and to provide a quality control metric to capture risk of FCOs in the early phase to minimize cost overruns in the project execution phase.</p></div>","PeriodicalId":35642,"journal":{"name":"Electricity Journal","volume":"37 6","pages":"Article 107424"},"PeriodicalIF":0.0,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141961099","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our results demonstrate that the interconnection line operates with a remarkably high utilization rate, ranging from 98.90 % to 99.95 % across all analyzed scenarios. This high utilization rate suggests that the project holds significant economic potential, with estimated net present values ranging from $1,786 million to $3,019 million at a discount rate of 7 %. Furthermore, from the sensitivity analysis on carbon price, discount rate, and transmission capacity, we show how the financial outcome of the project is affected by the change in these parameters. Finally, we discuss the consequence of imposing an additional constraint on the carbon emission to our model and then, minimizing the overall carbon emissions subject to keeping the overall cost without the interconnection.
