Transforming Dermatologic Imaging for the Digital Era: Metadata and Standards

Imaging is increasingly being used in dermatology for documentation, diagnosis, and management of cutaneous disease. The lack of standards for dermatologic imaging is an impediment to clinical uptake. Standardization can occur in image acquisition, terminology, interoperability, and metadata. This paper presents the International Skin Imaging Collaboration position on standardization of metadata for dermatologic imaging. Metadata is essential to ensure that dermatologic images are properly managed and interpreted. There are two standards-based approaches to recording and storing metadata in dermatologic imaging. The first uses standard consumer image file formats, and the second is the file format and metadata model developed for the Digital Imaging and Communication in Medicine (DICOM) standard. DICOM would appear to provide an advantage over using consumer image file formats for metadata as it includes all the patient, study, and technical metadata necessary to use images clinically. Whereas, consumer image file formats only include technical metadata and need to be used in conjunction with another actor—for example, an electronic medical record—to supply the patient and study metadata. The use of DICOM may have some ancillary benefits in dermatologic imaging including leveraging DICOM network and workflow services, interoperability of images and metadata, leveraging existing enterprise imaging infrastructure, greater patient safety, and better compliance to legislative requirements for image retention.

Optimal carbon capture and storage contracts using historical CO 2 emissions levels

In an effort to reduce carbon dioxide (CO 2 ) emissions to the atmosphere, carbon capture and storage (CCS) technology has been developed to collect CO 2 from emissions generators and store it underground. Recent proposed legislation would limit the volume of emissions generated from power sources, effectively requiring some sources to participate in CCS. Both emissions sources and storage operators require incentives to enter into contracts to capture excess emissions at the source, and transport and store the CO 2 underground. As the level of emissions from power plants is stochastic and carryover into future time periods is expensive, we develop a newsvendor model to determine the optimal price and volume of these contracts to maximize the expected profit of the storage operator and encourage the participation of multiple emissions sources. Because the storage operator has a limit on the amount of CO 2 that can be injected each month, this limit affects the allocation of the optimal contract amounts between the emitters. Furthermore, the distribution of emissions and relative costs of transportation also influence the optimal policy. In addition to analytical solutions, we present data-driven methods for using correlated emissions data to determine the optimal price and volume of these contracts.

Teens, Tweets, and Tanning Beds: Rethinking the Use of Social Media for Skin Cancer Prevention

The incidence of skin cancer is rising in the U.S., and melanoma, the deadliest form, is increasing disproportionately among young white women. Indoor tanning is a modifiable risk factor for all skin cancers and continues to be used at the highest rates in young white women. Adolescents and young adults report personal appearance–based reasons for using indoor tanning. Previous research has explored the influences on tanning bed use, including individual factors as well as relationships with peers, family, schools, media influences, legislation, and societal beauty norms. Adolescents and young adults also have high rates of social media usage, and research is emerging on how best to utilize these platforms for prevention. Social media has the potential to be a cost-effective way to reach large numbers of young people and target messages at characteristics of specific audiences. Recent prevention efforts have shown that comprehensive prevention campaigns that include technology and social media are promising in reducing rates of indoor tanning among young adults. This review examines the literature on psychosocial influences on indoor tanning among adolescents and young adults, and highlights ways in which technology and social media can be used for prevention efforts.

New Directions: GEIA’s 2020 Vision for Better Air Emissions Information

We are witnessing a crucial change in how we quantify and understand emissions of greenhouse gases and air pollutants, with an increasing demand for science-based transparent emissions information produced by robust community efforts. Today’s scientific capabilities, with near-real-time in-situ and remote sensing observations combined with forward and inverse models and a better understanding of the controlling processes, are contributing to this transformation and providing new approaches to derive, verify, and forecast emissions (Tong et al., 2011; Frost et al., 2012) and to quantify their impacts on the environment (e.g., Bond et al., 2013). At the same time, the needs for emissions information and the demands for their accuracy and consistency have grown. Changing economies, demographics, agricultural practices, and energy sources, along with mandates to evaluate emissions mitigation efforts, demonstrate compliance with legislation, and verify treaties, are leading to new challenges in emissions understanding. To quote NOAA Senior Technical Scientist David Fahey, "We are in the Century of Accountability. Emissions information is critical not only for environmental science and decision-making, but also as an instrument of foreign policy and international diplomacy." Emissions quantification represents a key step in explaining observed variability and trends in atmospheric composition and in attributing these observed changes to their causes. Accurate emissions data are necessary to identify feasible controls that reduce adverse impacts associated with air quality and climate and to track the success of implemented policies. To progress further, the international community must improve the understanding of drivers and contributing factors to emissions, and it must strengthen connections among and within different scientific disciplines that characterize our environment and entities that protect the environment and influence further emissions. The Global Emissions InitiAtive, GEIA (http://www.geiacenter.org/), is a center for emissions information exchange and competence building created in 1990 in response to the need for high quality global emissions data (Graedel et al., 1993). While the past two decades have seen considerable progress in developing, improving and assessing emission estimates, emissions continue to be a major contributor to overall uncertainty in atmospheric model simulations. Moving forward, GEIA aims to help build emissions knowledge in a rapidly evolving society by: 1) enhancing understanding, quantification, and analysis of emissions processes; 2) improving access to emissions information; and 3) strengthening the community of emissions groups involved in research, assessment, operations, regulation and policy.

Defining an industrial heat pump: A review & synthesis

Clear and understandable definitions of advanced energy technologies are not common and often confuse those who are not experts. This review paper addresses a critical issue in the field of heat pumps: the ambiguity surrounding the term “industrial heat pump.” The term, as discussed in various literature and media, often leads to misconceptions about the capabilities and applications of heat pumps, particularly in industrial contexts. This review paper seeks to refine and unify the definition of industrial heat pumps by analyzing existing academic and commercial literature, industry reports, and classifications. Unique identifiers explored for the definition of an industrial heat pump include the use of waste heat, operating temperature ranges, size specifications, and specific end-use applications. The study reveals differences in how industrial heat pumps are defined in academic and commercial contexts, highlighting the need for a standardized definition to facilitate better communication among manufacturers, policymakers, and end users. This is especially important considering recent legislative efforts such as the HEAT Act, which seeks to promote industrial heat pump adoption. The proposed definition aims to provide clarity while supporting the effective deployment of industrial heat pumps. With proper adoption, the definition will help promote the role of industrial heat pumps in achieving energy efficiency goals in the industrial sector. The intended impact is for the definition to serve as a foundational reference for future research and policy development.

Addressing trend-related changes within cumulative effects studies in water resources planning

Summarized herein are 28 case studies wherein trend-related causative physical, social, or institutional changes were connected to consequential changes in runoff, water quality, and riparian and aquatic ecological features. The reviewed cases were systematically evaluated relative to their identified environmental effects; usage of analytical frameworks, and appropriate models, methods, and technologies; and the attention given to mitigation and/or management of the resultant causative and consequential changes. These changes also represent important considerations in project design and operation, and in cumulative effects studies associated therewith. The cases were grouped into five categories: institutional changes associated with legislation and policies (seven cases); physical changes from land use changes in urbanizing watersheds (eight cases); physical changes from land use changes and development projects in watersheds (four cases); physical, institutional, and social changes from land use and related policy changes in river basins (three cases); and multiple changes within a comprehensive study of land use and policy changes in the Willamette River Basin in Oregon (six cases). A tabulation of 110 models, methods and technologies used in the studies is also presented. General observations from this review were that the features were unique for each case; the consequential changes were logically based on the causative changes; the analytical frameworks provided relevant structures for the studies, and the identified methods and technologies were pertinent for addressing both the causative and consequential changes. One key lesson was that the cases provide useful, “real-world” illustrations of the importance of addressing trend-related changes in cumulative effects studies within water resources planning. Accordingly, they could be used as an “initial tool kit” for addressing trend-related changes.

Spheres of public conversation: Experiences in strategic environmental assessment

This paper draws on earlier research, a national review of Scottish SEA practice and a survey of practitioners and stakeholders engaged in SEA and spatial planning in one Scottish city-region, to explore claims being made in the academic literature for Strategic Environmental Assessment (SEA) as a tool for deliberative plan-making. We consider whether there is evidence that Scottish SEA practice is helping create more inclusive plan-making processes in light of recent legislative changes, thereby fulfilling one of the expectations of Scottish Government. The macro analysis found that although there are opportunities for stakeholders to engage in the Scottish SEA process the level in practice is extremely low, a finding which mirrors experience in England and elsewhere. The more detailed micro analysis reveals a more nuanced picture within the spatial planning system, however, suggesting the existence of two distinct spheres of public conversations, one characterised by active dialogue about the environmental effects of alternative strategies amongst public sector stakeholders and the other involving non-governmental stakeholders and community groups in a much more limited way. The paper concludes with a discussion of possible explanations for this outcome, concerning asymmetric incentive structures and the application of power, and a consideration of the implications in relation to the competing discourses of SEA. -- Highlights: • We examine the extent to which Scottish SEA is helping promote inclusive plan-making. • Low levels of stakeholder engagement generally in Scottish SEA. • Stronger SEA dialogue amongst public agencies than with the wider community. • Importance of incentive structures and power capture in framing SEA public conversations.

A review of EIAs on trade policy in China: Exploring the way for economic policy EIAs

During the discussion on the “Environmental Protection Law Amendment (draft)” in 2011, it was decided to drop the proposed clauses related to environmental impact assessments (EIAs) on policy, which means that there remained no provisions for policy EIAs, and China's strategic environmental assessment system stayed limited to the planning level. However, considering that economic policy making is causing significant direct and indirect environmental problems and that almost every aspect of governmental policy has an economic aspect, EIAs on economic policies are of the utmost urgency. The purpose of this study is to review the EIA work that has been carried out on trade policy in China through four case studies, and illustrate how trade policy EIAs can be helpful in achieving better environmental outcomes in the area of trade. Through the trade policy EIA case studies we try to argue for the feasibility of conducting EIAs on economic policies in China. We also discuss the implications of the case studies from the point of view of how to proceed with EIAs on economic policy and how to promote their practice. - Highlights: • SEA system is incomplete and stays limited to the plan EIA level in China. • EIA on economic policy is of utmost importance for all the developing countries. • Four case studies of trade policy EIA in China are reviewed for policy implications. • Departmental competition for political power impedes economic policy EIAs in China. • Legislative regulation on policy EIA is the first thing needed to overcome barrier.

Including the temporal change in PM{sub 2.5} concentration in the assessment of human health impact: Illustration with renewable energy scenarios to 2050

This article proposes a new method to assess the health impact of populations exposed to fine particles (PM{sub 2.5}) during their whole lifetime, which is suitable for comparative analysis of energy scenarios. The method takes into account the variation of particle concentrations over time as well as the evolution of population cohorts. Its capabilities are demonstrated for two pathways of European energy system development up to 2050: the Baseline (BL) and the Low Carbon, Maximum Renewable Power (LC-MRP). These pathways were combined with three sets of assumptions about emission control measures: Current Legislation (CLE), Fixed Emission Factors (FEFs), and the Maximum Technically Feasible Reductions (MTFRs). Analysis was carried out for 45 European countries. Average PM{sub 2.5} concentration over Europe in the LC-MRP/CLE scenario is reduced by 58% compared with the BL/FEF case. Health impacts (expressed in days of loss of life expectancy) decrease by 21%. For the LC-MRP/MTFR scenario the average PM{sub 2.5} concentration is reduced by 85% and the health impact by 34%. The methodology was developed within the framework of the EU's FP7 EnerGEO project and was implemented in the Platform of Integrated Assessment (PIA). The Platform enables performing health impact assessments for various energy scenarios. - Highlights: • A new method to assess health impact of PM{sub 2.5} for energy scenarios is proposed. • An algorithm to compute Loss of Life Expectancy attributable to exposure to PM{sub 2.5} is depicted. • Its capabilities are demonstrated for two pathways of European energy system development up to 2050. • Integrating the temporal evolution of PM{sub 2.5} is of great interest for assessing the potential impacts of energy scenarios.

Environmental Impact Assessment in the Visegrad Group countries

Highlights: • Comparison and evaluation of EIA systems in the V4 countries are presented. • Strengths and weaknesses of EIA systems based on a questionnaire survey are stated. • The function and efficiency of the EIA application in the V4 countries are analysed. • Irregularities and shortcomings of EIA systems in the V4 should be eliminated. The Environmental Impact Assessment Directive (EIA Directive) has created a reference framework for the implementation of the system of Environmental Impact Assessment (EIA) into the legal systems of the Member States of the European Union, including the countries belonging to the Visegrad Group (V4): Poland, Slovakia, the Czech Republic and Hungary. The Directive was the basis for the introduction of compulsory stages of the EIA process in the V4. The stages were then adapted to national requirements, including thresholds of the qualifying criteria of projects at the screening and scoping stages. The EIA system in the analysed countries has been growing, changing and being modified together with the political and economic changes of the last 30 years. Although all Visegrad Group countries are members of the EU and should harmonize the provisions of the EIA Directive and its amendments, there still exist singularities in each country's national EIA legislation, in terms of complementarities among the V4 countries, access to information resources, protection of natural resources, mitigation of socio-environmental impacts, or transboundary impact assessment. The article compares and evaluates the EIA systems in the four countries, specifies similarities and differences in the implementation of administrative proceedings and points out opportunities to strengthen the system. It presents selected results of a study conducted in 2013 within the framework of the international project “Assessment of the quality of the environment in the V4 Countries” (AQE V4). This paper indicates examples of good practice in the EIA systems and the obtained results are compared regarding the amendments to the current European Union EIA Directive.

Stakeholder perceptions of Environmental Management Plans as an environmental protection tool for major developments in the UK

Insufficient implementation and the lack of legislative requirements for follow-up measures following the approval of projects are consistently highlighted as major shortcomings of Environmental Impact Assessment (EIA). Although adopted over 15 years ago by the World Bank, Environmental Management Plans (EMPs) were only semi-formalised in the UK in 2008 and arguably provide a continuous link or ‘bridge’ between the EIA process pre-consent and an Environmental Management System (EMS) post-consent. Drawing on twenty-one semi-structured interviews with stakeholders and thematic analysis of their responses, and a broad-scale practitioner survey, this study aimed to assess the effectiveness of EMPs as an environmental protection tool across the project lifecycle for major developments. The findings revealed a mixed picture of EMP effectiveness in practice, with EMPs only partially fulfilling a bridging role between EIA and EMS. There is no ‘gold standard’ terminology for EMPs, all having slightly different uses, thus presenting different focuses to different stakeholders and further enhancing variation in practice. For many stakeholders, the effectiveness was simply not known, due to the lack of communication and follow-up that still exists. EMP–EMS linkages were shown to be effective from the developer's perspective when a single organisation has involvement across all project phases, though weaknesses occur when multiple parties are involved. Among other stakeholders, knowledge varied significantly; whilst some were in agreement that the linkages worked, many were unaware of the connections and thought of them as two quite separate tools. Stakeholders advocated for the need to make EMPs a legal requirement; for improved communication between stakeholders during EMP implementation and increased documentation of project outcomes; and for EMPs to be consistently written by environmental professionals. Furthermore, weak links in the current process may be improved by providing detailed guidance for organisations on the potential for EMP–EMS linkages, with the additional aim of encouraging stakeholders to broaden their current specialist knowledge on environmental protection tools. - Highlights: • We assessed the effectiveness of Environmental Management Plans (EMPs) for major developments, focusing on delivery of mitigation and monitoring. • EIA and Environmental Management Systems (EMS) post-consent are weakly linked. • The use of EMPs varies significantly in practise, partly due to the range of terminology used. • Linkages are hampered by poor communication and follow-up • More detailed guidance on how EMPs can successfully link with EMS is required.

Bottom-up responses to environmental and social impact assessments: A case study from Guatemala

In this article we take a closer look at resistance to the practice of Environmental Impact Assessment (EIA) in mining and energy projects in Guatemala. Collectivities resisting mining and hydropower projects in Guatemala are increasingly using the evaluations of EIAs conducted by international independent professionals. Reaching out to international experts is facilitated by local communities' engagements in transnational networks bringing together activists, NGOs, scientists, journalists and others. We argue that resistance movements resort to international professionals to challenge the limits imposed on them by the national legislation and institutional arrangements as well as by the way in which EIAs are performed in the country. Further, the engagements in networks that facilitate access to knowledge contribute to strengthen the legitimacy of communities' claims. Challenges to and complaints about EIAs are ways in which affected communities try to reclaim their right to participate in decision-making related to their local environment and the development of their communities. Both complaints about EIAs and the use of transnational networks to attain better participation in decision making processes at local levels, illustrated in this study for Guatemala, are common responses to the advancement of extractive industries and hydropower development across Latin America. The widespread of initiatives to challenge EIAs involving international experts in the region show that EIAs have become a sort of a transnational battleground. - Highlights: • Communities’ opposition to extractive projects is rooted in lack of participation in decision-making, including EIAs • Experts’ evaluations of approved EIAs confirm communities’ claims of poor practices in the public sector • Research presented here shows that local communities linked to transnational networks are able to scale up their demands.

Reforming EIA systems: A critical review of proposals in Brazil

Environmental Impact Assessment (EIA) systems are under pressure in many countries, driven by a call for efficiency and streamlining. Such a phenomenon is particularly clear in Brazil, where, in the past few years, a number of influential associations put forward documents proposing significant changes to environmental licensing and impact assessment regulations. So far, there is no publicly available information about any initiative towards scrutinizing those proposals. The objective of this study was to critically review the merits and drawbacks of the changes proposed in those documents. The analysis triangulated content analysis, focus group and online survey data. The focus group included ten seasoned Brazilian EIA specialists; the survey, based on Likert-scale and open-ended questions, resulted in 322 valid responses from EIA professionals. Results show that the proposals generally agree that the current EIA system, while playing a key role in mitigating impacts and enhancing project design, needs many changes. Nonetheless, the proposals neither offered solutions to overcome political, technical and budget barriers, nor established a sense of priority of the most urgent issues. Findings from the focus group and the survey signaled that a number of proposed actions might face public outcry, and that those changes that do not depend on legislative action are more likely to be implementable. Previous studies about EIA reform focused mostly on the context of developed countries after changes had taken place. This study, while addressing the perspective of a large developing country in a “before-reform” stage, shows that capacity-building is a key requirement in EIA reform. - Highlights: • Brazil's EIA system is under strong pressure for change. • Findings corroborate ineffectiveness in current system. • There are tensions as to the best approaches to overcome problems. • Exact effects of proposals are uncertain. • Low institutional capacity can play strong role in driving EIA reform.

The impact of municipal budgets and land-use management on the hazardous waste production of Malaga municipalities

Economic development and the search for competitiveness have become key issues in regions' economic success. However, despite the direct relationship between economic and environmental management, few land-use plans consider the latter aspect, and city managers delegate the responsibility for environmental impacts to state legislation and private initiatives. This myopic search for competitiveness has meant that a holistic view of environmental issues is often not integrated into municipal decision-making processes. Therefore, this study's objective was to determine the relevant direct and indirect relationships of land management and budgetary procedures of municipalities with overall production levels of hazardous waste. To this end, a primary tourist region, Málaga, was examined in terms of how this waste's environmental impacts can affect the region's vital tourism sector. This research used principal component analysis, regression by ordinary least squares, cluster analysis in two stages and a means test to compare the data for the Province of Malaga's subregions. The results confirm a positive relationship between municipal expenditure and waste production and highlight the environmental benefits of land use involving environmentally non-aggressive crops. The results also reveal a negative relationship between waste production and financial assets and a direct relationship between unproductive land and the production of hazardous waste. The findings also highlight the necessity of raising awareness about the need for collaboration between different agents, especially in the development of inter-municipal strategies.

Evaluation of the environmental impact assessment system and implementation in Myanmar: Its significance in oil and gas industry

Myanmar's political and economic transformation and drastic expansion of foreign direct investment in natural resource sector necessitate systematic safeguards to mitigate impacts from its development activities. Myanmar promulgated the first national EIA law and procedure only recently, in 2016, and the country's institutional and financial capacity is extremely limited to implement effective EIA. This article evaluates Myanmar's EIA system against a set of evaluative criteria developed by Wood (1995) and modified by Annandle (2001). The evaluation was based on the review of the literature, investigation of EIA legislative and administrative framework, and several other sources of data and information. Opinions of professionals from international and government agencies, and researchers are also solicited. The paper then evaluates the rate of EIA disclosure in O&G sector and whether EIA in Myanmar is significance in mitigating the impact of O&G operations on the environment. The review of EIA system indicates that Myanmar generally has sound legal and administrative framework for EIA, however, its practical implementation reveals several major challenges and weaknesses. The presence of more than one standard EIA procedure and lack of inter-departmental coordination and consultation are also major concerns. Overall, the quality of EIA reports and the level of disclosure in O&G sector is higher than that of other sectors in Myanmar. Through the analysis, the paper summarizes the fundamental challenges faced by companies and government, opportunities and good practices in implementing EIA systems and propose recommendations to strengthen EIA performance. The findings of this study expect to contribute to strengthening EIA system and performance in Myanmar and other developing countries, especially in Southeast Asia.

Environmental licensing in Brazilian's crushed stone industries

Highlights: • Failures in environmental reporting compromise the effectiveness of the environmental license process • The infrastructure of environmental agencies must be improved • The participation of society is essential for monitoring industries - Abstract: The crushed stone industries' activities are characterized by the extraction and processing of stones for use as aggregates in construction. The sector causes environmental impacts that can be mitigated by the implementation of control instruments, namely, environmental licensing, whose purpose is to carry out monitoring of potentially polluting activities. In this paper, it was analyzed the environmental studies of three industries located in Monsenhor Gil, Piauí, Brazil, elaborated as requisites for obtaining the environmental and mineral licenses. There were made visits to the State Department of Environment and Water Resources (SEMAR) and to the National Department of Mineral Production (DNPM) to verify the environmental reports and the environmental and mineral licensing processes. There were also made visits to the analyzed industries, with the aim of comparing the information contained in the studies, with the reality and verifying the implementation of the mitigating measures proposed in them, through the observation of the industries operation, and interviews with the responsible managers. Furthermore, it was made a research in the scientific literature, to know the licensing process in other countries, to compare with the Brazilian reality. From the research, in Brazilian industries, it was observed that, although all the legal steps to obtain the licenses have been fulfilled, the environmental reports have elaboration failures, such as the lack of a multidisciplinary team and the fact that some data diverge from the reality, decreasing the reliability of the evaluation of the environmental impacts caused by the projects. Also, the environmental replacement cost is not accounted in the final value of the product, and any of the industries have started the implementation of the proposed mitigation measures since they do not have mineral depletion areas. SEMAR was delayed in issuing licenses within the period established by law, and there are no periodic inspections by both the environmental agency and DNPM. It should also be pointed out that the community did not claim public hearings and there is no participation in environmental education projects, factors that compromise the effectiveness of the environmental licensing process. Regarding the process in other parts of the world, in some countries, such as Uruguay and Paraguay, the agency responsible for licensing and inspection is federal. In Argentina, as in Brazil and USA, states have autonomy to legislate on environmental issues. There is also divergence in the period of execution of the licenses, being 12 months in Brazil, while in Thailand it can be up to 56 days. In Peru, the society participation is much more representative than in Brazil, and there is differentiation in the collection form of environmental compensation fees, among countries. The failures pointed out in the Brazilian process, as well as the system of other countries, can serve as parameters for the improvement of the process' effectiveness, both in Brazil and in other parts of the world, aiming at the conservation of the environment.

Implementing next generation assessment: A case example of a global challenge

IA regime design has evolved significantly over the past 50 years. Current thinking includes a package of next generation approaches such as the incorporation of requirements for regional and strategic IA, the consideration of cumulative effects and alternatives, and the inclusion of sustainability criteria and trade-off rules for decision makers. These suggested changes to IA design largely come from the recognition, through experience, of the weaknesses with current IA laws and regulations and needs to accommodate new understandings, for example about sustainability and complexity. Here, we reiterate the key generic components of next generation assessment that are broadly suitable for application in all jurisdictions with at least moderate assessment capacities, focusing on the necessary process requirements that could be captured in IA law, regulation and policy. Through an illustrative case example of Manitoba, Canada, we show how the components of next generation assessment might be implemented as a package in the context of an existing IA regime. Our application of these principles reveals the value of careful consideration of the current legislative frame as well as needs to cooperate with other jurisdictions. It shows, for example, the importance of experience with using streams of assessment and ensuring meaningful public participation. We conclude that many jurisdictions are likely to find moving consistently to this more comprehensive form of assessment to be a natural progression and that the greatest challenges will probably be in building interjurisdictional cooperation, ensuring good faith application of the sustainability criteria in decision making, and implementing regional and strategic assessments.

Self-consumption for energy communities in Spain: A regional analysis under the new legal framework

European climate polices acknowledge the role that energy communities can play in the energy transition. Self-consumption installations shared among those living in the same building are a good example of such energy communities. In this work, a regional analysis of optimal self-consumption installations under the new legal framework recently passed in Spain is performed. Results show that the optimal sizing of the installation leads to economic savings for self-consumers in all the territory, for both options with and without remuneration for energy surplus. A sensitivity analysis on technology costs revealed that batteries still require noticeably cost reductions to be cost-effective in a behind the meter self-consumption environment. In addition, solar compensation mechanisms make batteries less attractive in a scenario of low PV costs, since feeding PV surplus into the grid, yet less efficient, becomes more cost-effective. Furthermore, an improvement for the energy surplus remuneration policy in the context of the current legislation was proposed and analysed. It consists in the inclusion of the economic value of the avoided power losses in the remuneration.
