Background

This research study applied the 'Integrated Energy Landscape Approach and the Ecosystem Services Framework' to formulate a pre-proposal for a Positive Energy District in the Hoogkerk Zuid neighborhood in Groningen, the Netherlands.

Results

The proposed energy saving and energy generation interventions are sufficient to cover the energy usage of the district, while an energy surplus is generated. The pre-proposal has been developed within a participatory process, organized by the authors in close collaboration with key local stakeholders. The identification of local ecosystem services served as a crucial starting point for this study, while it also served for the basis for analysing the subsequent trade-offs and synergies derived from the proposed energy transition interventions. Then, a sustainable business case model was developed based on this Positive Energy District pre-proposal. The main outcome of the model lies in the value creation through cost savings from not using traditional energy sources and selling electricity to the grid. In addition, the economic value of the preserved ecosystem services and of the synergies generated by the pre-proposal are also included in the model.

Conclusions

Beyond the local case, the results lay the groundwork for more systematic studies on merging the methodologies of Positive Energy District development, the Ecosystem Framework and the Integrated Energy Landscape approach. Finally, by adding the benefits of ecosystem services and synergies as a significant contributor in the financial analysis and decision-making process, this study opens the door to a new approach to the evaluation of sustainable projects.

本研究应用“综合能源景观方法和生态系统服务框架”,为荷兰格罗宁根Hoogkerk Zuid社区的正能量区制定了一个预先建议。结果提出的节能和发电干预措施足以覆盖该地区的能源使用,同时产生了能源盈余。预提案是在参与性过程中制定的,由作者与当地主要利益相关者密切合作组织。确定当地生态系统服务是本研究的关键起点,同时也为分析拟议的能源转型干预措施所产生的后续权衡和协同效应提供了基础。在此基础上,构建了一个可持续发展的商业案例模型。该模式的主要成果在于通过不使用传统能源和向电网出售电力而节省成本来创造价值。此外,保留的生态系统服务的经济价值和预先建议产生的协同作用也包括在模型中。除了本地案例,研究结果还为将正能量区开发方法、生态系统框架和综合能源景观方法相结合的系统研究奠定了基础。最后,通过将生态系统服务和协同效应作为财务分析和决策过程中的重要因素,本研究为可持续项目的评估开辟了一种新的方法。

Background

The circular economy represents a vision of ever-increasing importance for policy making. In this paper, the circularity of transportation fuel production systems is explored, as energy carriers are seldom the focus of existing methods. A theoretical framework for understanding the circularity of energy carriers was devised based on the renewability and secondary fractions of inputs and the recycling of outputs, which cover both biological and technical cycles. Based on this framework, and with input from actors working in the field of transport fuels, a six-step method was developed to assess the circularity of energy carriers. The method uses a life cycle perspective for assessing energy carriers across their life cycle.

Results

This method was applied to four production systems in the Swedish context: hydrogenated vegetable oil (HVO) from tall oil, ethanol from forest residues, biomethane from household food waste, and battery–electric mobility. The results showed that all studied biofuels have a high degree of circularity due to the use of secondary materials as a feedstock. The biomethane system scored the highest percentage, with a circularity score of 81%, while the HVO and ethanol systems only reached a score of 75% and 45%, respectively. The battery–electric system, on the other hand, performed worse at only 17% circularity due to the low degree of circularity in the battery production. One “greening” scenario was tested for each production system to explore the impact of possible future improvements.

Conclusions

The results showed that second-generation biofuels align well with the circular economy concept as they upcycle low-value resources into high-value products. At the same time, electric mobility requires a higher degree of material recirculation to further align it with the circular economy. Furthermore, all production systems indicated improvement potentials and should, therefore, be aimed at increasing their recirculation rates and use of renewable resources. In conclusion, this article gives valuable input into the broader decision process to determine which fuels should be promoted during the transition away from fossil fuels, as circularity is one aspect to be considered.

循环经济代表了一种对政策制定日益重要的愿景。由于能源载体很少是现有方法的重点,因此本文探讨了运输燃料生产系统的循环性。基于可再生性和投入的次级部分以及产出的再循环,设计了一个理解能量载体循环性的理论框架,涵盖了生物和技术循环。基于这一框架,并结合运输燃料领域工作人员的意见,开发了一种六步方法来评估能源载体的循环性。该方法使用生命周期视角来评估整个生命周期的能量载体。该方法应用于瑞典的四种生产系统:从塔尔油中提取氢化植物油(HVO),从森林残留物中提取乙醇,从家庭食物垃圾中提取生物甲烷,以及电池-电动交通。结果表明,由于使用二次材料作为原料,所有研究的生物燃料都具有高度的循环性。生物甲烷系统的循环度得分最高,达到81%,而HVO和乙醇系统分别仅达到75%和45%。另一方面,由于电池生产的低循环度,电池-电力系统的表现更差,只有17%的循环度。每个生产系统都测试了一个“绿化”场景,以探索未来可能的改进的影响。结果表明,第二代生物燃料很好地符合循环经济概念,因为它们将低价值资源升级为高价值产品。与此同时,电动交通需要更高程度的材料再循环,以进一步与循环经济保持一致。此外,所有生产系统都显示出改进的潜力,因此应着眼于提高其再循环率和利用可再生资源。总之,本文为更广泛的决策过程提供了有价值的输入,以确定在从化石燃料过渡期间应该推广哪些燃料,因为循环是需要考虑的一个方面。

Background

Sustainable development is not possible without sustainable energy, and while renewable energy minigrid and microgrid systems are regarded as a promising solution for achieving energy transition and supporting rural development in the global south, the complex relationship between the adoption of renewable energy systems and land tenure systems within rural communities remains a critical aspect that has often been overlooked in this context. This study addresses this gap by examining how small-scale community-based renewable energy systems influence land tenure transformations and whether shifts in land tenure patterns drive changes in renewable energy adoption and management strategies.

Results

This research adopts a qualitative comparative case study methodology, examining six community-based solar energy projects in Ethiopia, Uganda, Kenya, Namibia, Indonesia, and Peru. Using an adapted socio-ecological systems framework based on Ostrom’s principles, the study analyzes six outcome parameters: governance, land tenure, socio-spatial relations, economic dependencies, perception, and behavior. The findings reveal complex interactions between land tenure and renewable energy adoption, demonstrating that the introduction of renewable energy systems has the potential to reshape land tenure paradigms. Specifically, changes in socio-spatial relations and economic dependencies were identified as key factors that influence community responses to renewable energy projects. These shifts also affect local governance structures, perceptions, and community behavior towards both land and energy systems.

Conclusions

The results highlight the need for a comprehensive understanding of the interactions between land tenure and renewable energy initiatives to foster effective rural development. Recognizing these dynamics can inform policy and practice, ensuring that renewable energy interventions are aligned with local land tenure realities and contribute to sustainable socio-economic transformations.

背景:没有可持续能源就不可能实现可持续发展,虽然可再生能源微型电网和微电网系统被认为是实现能源转型和支持全球南方农村发展的有希望的解决方案,但在这种情况下,采用可再生能源系统与农村社区土地权属制度之间的复杂关系仍然是一个经常被忽视的关键方面。本研究通过考察小规模社区可再生能源系统如何影响土地权属转变,以及土地权属模式的转变是否推动可再生能源采用和管理战略的变化,解决了这一差距。本研究采用定性比较案例研究方法,考察了埃塞俄比亚、乌干达、肯尼亚、纳米比亚、印度尼西亚和秘鲁的六个社区太阳能项目。利用基于Ostrom原则的适应性社会生态系统框架,该研究分析了六个结果参数:治理、土地使用权、社会空间关系、经济依赖、感知和行为。研究结果揭示了土地权属与可再生能源采用之间复杂的相互作用,表明可再生能源系统的引入有可能重塑土地权属模式。具体而言,社会空间关系和经济依赖关系的变化被确定为影响社区对可再生能源项目反应的关键因素。这些转变也影响了地方治理结构、观念和社区对土地和能源系统的行为。研究结果强调,为了促进有效的农村发展,需要全面了解土地所有制与可再生能源倡议之间的相互作用。认识到这些动态可以为政策和实践提供信息,确保可再生能源干预措施与当地土地权属现实保持一致,并有助于可持续的社会经济转型。

Background

This paper aims to analyze, synthesize and evaluate the main differences, similarities, advantages, and disadvantages of the narratives of green economy (GE), circular economy (CE) and bioeconomy (BE) models within a sustainability framework. The article seeks to provide a critical comparison of the notion of three models, related in their concepts, approaches and tools, as well as establish and analyze the strategies that lead to a change in the dominant paradigms in sustainability applications.

Main text

The emerging green, circular and bioeconomy approaches focus on proposing strategies that lead to sustainability. This study shows that despite their notable conceptual differences, a model that adapts to rapid changes in the needs and limitations of natural resources is common across all approaches. However, in terms of analysis and application, they are not always clear because of the complexity of differentiating approaches, conceptual incorporation frameworks and analytical tools. The results show that, in the environmental dimension, the circular economy and bioeconomy focus on resource management, whereas the green economy starts by analyzing ecological processes to reduce environmental risk and ecological scarcity. In the economic dimension, the circular economy aims to decouple economic growth from environmental pressure, whereas the bioeconomy emphasizes the processing and enhancement of biological raw materials to foster new value chains.

Conclusions

The findings of this paper clarify the limits, synergies, and differences in sustainability between the concepts of the green economy (GE), the circular economy (CE) and the bioeconomy (BE), and address gaps in the literature. These concepts continue to be limited by their economic growth; limits in the interrelation between the biosphere and individuals; and specific assessments of the environmental, social, and economic aspects of sustainable management.

本文旨在分析、综合和评价可持续发展框架下绿色经济(GE)、循环经济(CE)和生物经济(BE)模型叙事的主要异同、优缺点。本文试图对三种模式的概念进行批判性的比较,这些模式在概念、方法和工具上都是相关的,并建立和分析导致可持续性应用中主导范式变化的策略。新兴的绿色、循环和生物经济方法侧重于提出导致可持续性的战略。这项研究表明,尽管它们在概念上存在显著差异,但所有方法都有一个适应自然资源需求和限制迅速变化的模式。然而,在分析和应用方面,由于不同的方法、概念整合框架和分析工具的复杂性,它们并不总是明确的。结果表明,在环境维度上,循环经济和生物经济侧重于资源管理,而绿色经济则从分析生态过程入手,降低环境风险和生态稀缺性。在经济层面,循环经济旨在将经济增长与环境压力脱钩,而生物经济则强调对生物原料的加工和强化,以培育新的价值链。本文的研究结果阐明了绿色经济(GE)、循环经济(CE)和生物经济(BE)概念在可持续性方面的局限性、协同作用和差异,并解决了文献中的空白。这些概念继续受到其经济增长的限制;生物圈与个人之间相互关系的限度;以及对可持续管理的环境、社会和经济方面的具体评估。

Background

Dramatic reductions in anthropogenic CO2 emissions are needed to mitigate the impacts of rapidly accelerating climate change. In Sweden and Finland efforts to realize the political ambitions to meet international climate objectives, and promote the growth of ‘green’ industries, have focused on rapid expansion of wind farms, but in both countries wind power developments have been controversial. These controversies are especially prominent in the northern regions of the countries which have become hotspots of wind power development. In this article, we focus on these regional wind power debates with the aim to extend scholarly understanding of the spatial justice dimensions of how ‘just’ and ‘green’ transitions unfold. We do this by examining representations of the ways in which the effects of regional wind power development, their management and the ‘right’ places for wind power are debated in 372 articles in Swedish and Finnish regional news media published during 2020–2023.

Results

In regional media representations, wind power is discussed in terms of a wide range of experienced and potential impacts. Negative impacts including harm to the environment, biodiversity and human health are discussed. Yet, the positive effects are emphasized, including contributions to national policy goals and the regional socioeconomic benefits of the emergence of a green, low-carbon economy in both the Swedish and Finnish articles. However, envisioned means for managing wind power development in a fair manner differ: compensations and the right to municipal veto are strongly highlighted in the Swedish articles, while Finnish articles focus on the integrity of democratic processes and planning. As the green transition continues to unfold, northern regions are increasingly being represented as the ‘right’ places for wind power, both from outside and within those regions.

Conclusions

Our findings highlight the perceived importance of local and regional socioeconomic benefits and local self-determination for positive perceptions of large-scale wind power developments in our focal administrative and legal contexts. Local and regional histories and encounters with earlier resource development continue to shape reactions to and interpretations of resource development projects in contemporary Euro-Arctic North.

背景:为了减轻迅速加速的气候变化的影响,需要大幅度减少人为的二氧化碳排放。在瑞典和芬兰,为了实现实现国际气候目标的政治雄心,并促进“绿色”产业的发展,他们的努力都集中在风力发电场的快速扩张上,但在这两个国家,风力发电的发展一直存在争议。这些争议在已成为风电发展热点的国家北部地区尤为突出。在本文中,我们将重点关注这些区域风电辩论,旨在扩展对“公正”和“绿色”转型如何展开的空间正义维度的学术理解。为此,我们研究了瑞典和芬兰地区新闻媒体在2020-2023年期间发表的372篇文章中对区域风力发电发展的影响、管理和“正确”风力发电地点的讨论方式。结果在区域媒体报道中,风力发电被广泛地从经验和潜在影响的角度来讨论。讨论了对环境、生物多样性和人类健康的危害等负面影响。然而,瑞典和芬兰的文章都强调了积极的影响,包括对国家政策目标的贡献以及绿色低碳经济的出现所带来的区域社会经济效益。然而,以公平的方式管理风力发电开发的设想手段有所不同:瑞典的条款强烈强调了补偿和市政否决权,而芬兰的条款则侧重于民主进程和规划的完整性。随着绿色转型的继续展开,北方地区越来越多地被认为是风力发电的“正确”地点,无论是外部还是内部。我们的研究结果强调了地方和区域社会经济效益和地方自决对我们重点行政和法律背景下大规模风电开发的积极看法的重要性。当地和地区的历史以及与早期资源开发的接触继续塑造对当代欧洲-北极北部资源开发项目的反应和解释。

Background

The biogas niche is usually approached from a top-down perspective, and its actors are considered a unanimous advocacy group in the national policy discourse. This setting downplays the diversity of actors and their opinions at a subnational level.  In this study, ten biogas actors from the farm-level, industry, regional administration, and potential end-users in the Finnish region of Northern Savonia were interviewed. The actors’ perceptions of the national and regional biogas sectors were explored.

Results

The national biogas policy framework appears discontinuous, and statements regarding biogas targets are perceived as ambiguous, thus lacking creditability at a local level. The economic feasibility of rural biogas production places a strong boundary condition for the local biogas system. When moving from the national to a local level, individual actor’s perception of the optimal value chain becomes highlighted. Extending the actor network beyond the regional context was deemed vital for the long-term stability of the locally emergent biogas ecosystem. As municipalities can influence both production and consumption domains, they were called to play a more active role in constructing local biogas systems.

Conclusions

The results of this study provided three insights: (1) social, political, and environmental drivers influence the biogas sector in addition to techno-economic drivers; (2) drivers and constraints are perceived differently by actors in agricultural biogas production than by actors in distribution and end-use; and (3) the local biogas niche contains partly divergent perceptions of how the biogas system should be organised. Connecting actors early through joint planning and formulating case-by-case business models may help mediate any conflicts of interest.

沼气生态位通常是从自上而下的角度来看待的,它的参与者被认为是国家政策话语中一致的倡导团体。这种情况淡化了国家以下一级行为者及其意见的多样性。在这项研究中,来自芬兰北部萨沃尼亚地区农场、工业、地区管理和潜在最终用户的10位沼气参与者接受了采访。探讨了参与者对国家和区域沼气部门的看法。结果国家沼气政策框架似乎不连续,关于沼气目标的陈述被认为是模糊的,因此在地方层面缺乏可信度。农村沼气生产的经济可行性为当地沼气系统提供了强有力的边界条件。当从国家层面转移到地方层面时,个体行动者对最优价值链的感知变得突出。将行动者网络扩展到区域范围之外,对于当地新兴的沼气生态系统的长期稳定至关重要。由于市政当局可以影响生产和消费领域,因此要求它们在建设地方沼气系统方面发挥更积极的作用。结论:(1)除技术经济驱动因素外,社会、政治和环境驱动因素也对沼气行业产生影响;(2)农业沼气生产参与者对驱动因素和制约因素的认知不同于分销和最终利用参与者;(3)当地的沼气生态位包含了对沼气系统应该如何组织的部分不同看法。通过联合规划和制定个案业务模型,尽早将参与者联系起来,可能有助于调解任何利益冲突。

Background

Domestic energy consumption contributes to over a quarter of the UK’s carbon emissions, understanding how it is driven can be helpful for delivering a fair energy transition to net zero. Energy usage is noted as a spatial phenomenon, however, the spatial variability of how it is driven is rarely considered in existing UK studies. To contribute to this research gap, this study examines the spatial variations in the relationship between domestic energy consumption and its driving factors using the local spatial statistical modelling technique multiscale geographically weighted regression (MGWR). With explanatory variables on dwelling and household characteristics, this study analyses data at Lower Layer Super Output Area (LSOA) level on the study area, Nottingham, a somewhat socio-economically deprived city that also has the UK’s largest district heating (DH) system supplying low-carbon residential heating.

Results

The study reveals domestic energy consumption is driven by factors at different spatial scales with spatially varied or even spatially heterogeneous patterns. Specifically, higher domestic energy consumption is affected differently across local areas by larger percentages of dwellings with 4 or more bedrooms, unemployment, terraced dwellings, whilst by smaller percentages of social-rented housing tenures and central heating type of district heating. The impacts of dwelling energy efficiency, median household income, percentage of households with 3 or more people, fuel poverty, and central heating with renewable energy, vary across different local areas. Therefore, while there are identifiable relationships between these factors and domestic energy consumption, they differ by locality, and aggregated level analysis may fail to accurately to capture these patterns.

Conclusions

Nuanced local patterns of how domestic energy consumption is driven suggest placed-based approaches and more local deliberation to devise policies may be more suitable than “one-size-fit-all” policy plans to achieve the envisioned outcomes of rapid and fair domestic energy decarbonisation and just energy transition to net zero.

国内能源消费占英国碳排放量的四分之一以上,了解它是如何驱动的,有助于实现向净零的公平能源转型。能源使用被认为是一种空间现象,然而,在现有的英国研究中,很少考虑能源使用方式的空间变异性。为了弥补这一研究空白,本研究利用多尺度地理加权回归(MGWR)局部空间统计建模技术,分析了国内能源消费及其驱动因素之间的空间差异。通过住宅和家庭特征的解释变量,本研究分析了研究区域下层超级输出区(LSOA)水平的数据,诺丁汉是一个社会经济程度较低的城市,也拥有英国最大的区域供热(DH)系统,提供低碳住宅供暖。结果国内能源消费受不同空间尺度因素驱动,存在空间差异甚至异质性格局。具体而言,在不同地区,较高的家庭能源消耗受到较大比例的4间或更多卧室住宅、失业、排屋的影响,而受到较小比例的社会租赁住房和集中供热类型的区域供热的影响。住宅能源效率、家庭收入中位数、3人以上家庭比例、燃料贫困和可再生能源集中供暖的影响因地区而异。因此,虽然这些因素与家庭能源消费之间存在可确定的关系,但它们因地区而异,综合水平分析可能无法准确地捕捉到这些模式。结论:国内能源消费驱动的本地模式表明,基于地方的方法和更多的地方审议来制定政策可能比“一刀切”的政策计划更适合实现快速和公平的国内能源脱碳和公正的能源净零转型的预期结果。

Background

This paper seeks to explore the roles of distribution system operators (DSOs) in future energy systems. Measures to combat climate change have led to a transition in the energy sector, where old system fundamentals are becoming obsolete, which results in changing rules for incumbent actors, such as DSOs. These actors must uphold heavily regulated operations within their distribution networks, while landscape trends are changing with a growing number of prosumers and distributed energy resources. To understand these future roles and increase the preparedness for future scenarios and facilitate thinking beyond current lock-ins, action-oriented workshops were held with two Swedish DSOs, departing from pre-developed future imaginaries, structured through transition theory. Researchers were actively involved in the workshops, to guide the participants in the discussions and to provide additional knowledge from transition processes. This was structured through transition theory, mainly in terms of linking transition management fundamentals to the topics in the workshops and basing the workshop discussions on an imagined future socio-technical system-wide approach using four focus areas.

Results

Results included descriptions of roles within future energy systems and their connection to specified value logics from different target groups which would, from the DSO perspective, create value in a future energy system. Roles included sustainable developer, facilitator for increased collaboration, balancing actor, and communicator. In addition, competence requirements were outlined concerning the described roles. The future logic was also described in a conceptual value model for an active DSO in a prosumer-oriented energy system, creating value in all different value logics. Moreover, it provided the steps necessary to develop a pathway aimed at the transformation of DSOs.

Conclusions

The study provided a constructive approach for DSOs to prepare for a future, more prosumer-oriented and flexible energy system, avoiding being locked in current system thinking and focusing on necessary roles and competencies suitable for a DSO. In addition, the utilization of the value logics approach helped place the prosumers in a differentiated manner, which can have implications for strategies among DSOs to create the necessary relations and collaborations for an efficient and value-creating future energy system.

本文旨在探讨配电系统运营商(dso)在未来能源系统中的作用。应对气候变化的措施导致了能源部门的转型,旧的系统基本原理正在过时,这导致了现有参与者(如dso)的规则发生了变化。这些参与者必须在其分销网络中维持严格监管的运营,而随着产消者和分布式能源数量的增加,格局趋势正在发生变化。为了了解这些未来的角色,增加对未来情景的准备,并促进超越当前锁定的思考,与两个瑞典dso一起举办了以行动为导向的研讨会,从预先开发的未来想象出发,通过过渡理论构建。研究人员积极参与讲习班,指导与会者进行讨论,并从过渡过程中提供额外的知识。这是通过过渡理论来组织的,主要是将过渡管理基本原理与讲习班的主题联系起来,并将讲习班讨论建立在设想的未来社会技术全系统方法的基础上,使用四个重点领域。结果包括对未来能源系统中角色的描述,以及它们与来自不同目标群体的特定价值逻辑的联系,从DSO的角度来看,这些目标群体将在未来能源系统中创造价值。角色包括可持续开发人员、促进协作的推动者、平衡参与者和沟通者。此外,还概述了关于所述角色的能力要求。在面向产消能源系统中主动DSO的概念价值模型中也描述了未来逻辑,在所有不同的价值逻辑中创造价值。此外,它还提供了必要的步骤,以发展一条旨在改变发展中国家社会组织的途径。结论该研究为DSO为未来更加以产消费者为导向和灵活的能源系统做准备提供了建设性的方法,避免被当前的系统思维所锁定,并关注适合DSO的必要角色和能力。此外,价值逻辑方法的使用有助于将产消者以差异化的方式放置,这可能对dso之间的战略产生影响,从而为高效和创造价值的未来能源系统创建必要的关系和合作。

Background

The shift from fossil fuels to renewable energy sources brings substantial changes in land use. Germany, with limited land availability, needs a spatial framework to allocate renewable energy while safeguarding biodiversity and ecosystem services. This process should include public participation at the local level. Respective models have been developed for decision support on wind turbine allocation but methods are still lacking for solar parks. This paper aims to identify the safe operating space for solar energy supply that is inclusive and compatible with humans and nature. We propose criteria for Germany with different classes of legal legitimization to define the local decision space. The method is applied in the exemplary case of the federal state of Lower Saxony and the two municipalities—Springe and Wedemark.

Results

The results show that this decision space is sufficiently large to involve both the local public and decision-makers in determining the energy mix and siting of renewable plants. In Lower Saxony, 13% of the state's area (611.932 ha) has low spatial resistance to solar parks. With a reference plant's power density of 1.01 MW/ha, this land could generate up to 667 TWh/a, far exceeding the share needed for Lower Saxony’s contribution to Germany’s projected energy demand in 2050. This provides flexibility for regional and local stakeholders to shape their energy landscape within the bounds of downscaled national climate targets and human- and nature-compatible development. In addition, co-benefits with other extensive land-use objects, such as groundwater protection, can be provided on these sites.

Conclusions

Our findings offer valuable guidance for regional planning boards and encourage public participation in the decision-making process by providing transparent information about the spatial options and limits of solar development. The model can improve planning, since different planning levels could access and utilize the scalable data. Equal criteria at all levels increase the intersubjectivity and comprehensibility of approval decisions and thus also the legal certainty of land designations for solar parks.

从化石燃料到可再生能源的转变带来了土地利用的重大变化。德国土地资源有限,需要一个空间框架来分配可再生能源,同时保护生物多样性和生态系统服务。这一进程应包括公众在地方一级的参与。在风力发电机组配置决策支持方面,已经建立了相应的模型,但在太阳能发电园区的决策支持方面还缺乏相应的方法。本文旨在寻找包容、兼容人与自然的太阳能供电安全运行空间。我们针对德国提出了不同类别的法律合法化标准来界定地方决策空间。该方法应用于联邦下萨克森州和两个市(springe和Wedemark)的示例案例。结果该决策空间足够大,可让当地公众和决策者共同参与能源结构和可再生能源电厂选址的决策。在下萨克森州,该州13%的面积(611.932公顷)对太阳能公园的空间阻力较低。参考电厂的功率密度为1.01兆瓦/公顷,这片土地的发电量可达667太瓦时/年,远远超过下萨克森州2050年对德国预计能源需求的贡献。这为区域和地方利益相关者提供了灵活性,使其能够在缩小的国家气候目标和人类与自然兼容的发展范围内塑造其能源格局。此外,可以在这些场址上与其他广泛的土地利用对象,例如地下水保护,提供共同利益。研究结果为区域规划委员会提供了有价值的指导,并通过提供有关太阳能开发的空间选择和限制的透明信息,鼓励公众参与决策过程。该模型可以改进规划,因为不同的规划级别可以访问和利用可伸缩的数据。各级的平等标准增加了批准决定的主体间性和可理解性,从而也增加了太阳能公园土地指定的法律确定性。

Background

The European Green Deal has rekindled interest in the mining of critical raw materials within Europe’s borders. The Weinebene lithium deposit, near Wolfsberg (Austria), deemed uneconomic as late as the 2000s, has attracted interest from developers because of the widespread demand for the metal for battery technology and in the electro-mobility sector. Based on a multi-scalar analysis, the main objective of this study is to investigate local citizens’ and politicians’ perceptions of potential environmental and socio-economic impacts of the Wolfsberg project. We deploy an interdisciplinary political geology approach that assesses its geological feasibility, social acceptability and the associated power relations, in the light of European debates around so-called ‘green extractivism’.

Results

The exploitation of the lithium deposit seems to be promising from a geological point of view: the Weinebene hard rock, vein-type spodumene deposit was assessed at 12.9 Mt grading 1% Li2O, and the planned mine could provide 10,500 tpa LiOH/year for a period of 20 years, which would be around 4.5% of global production in 2021. However, the main results of the study show that conflicts are emerging around local environmental impacts, for example, the increase of traffic. Such environmental impacts resulting in greater CO2 emissions contradict decarbonisation objectives and ecological transitions. Local youth and politicians have highlighted the possibility of local mineral production, job creation and economic development. Nevertheless, politicians have criticized the company’s communication policy.

Conclusions

The geological analysis suggests adequate lithium resources. Otherwise, the Wolfsberg project is undermined by the lack of an open public dialogue on its future. Local residents and politicians are barely involved in the planning and permitting stages. The company European Lithium is confident of starting extraction soon, but in reality this is still uncertain. More widely, our results point towards the need for a strong degrowth strategy to generally reduce mineral consumption in Europe while also stopping destructive mining projects in the Global South. Local public perceptions have to be taken more into account when it comes to the future of lithium extraction in Europe’s ‘backyard’. Mechanisms need to be developed to fully integrate local residents into decision making processes.

《欧洲绿色协议》重新燃起了人们对在欧洲境内开采关键原材料的兴趣。奥地利沃尔夫斯堡(Wolfsberg)附近的Weinebene锂矿床直到2000年代还被认为不经济,但由于电池技术和电动汽车领域对这种金属的广泛需求,该矿床吸引了开发商的兴趣。基于多标量分析,本研究的主要目的是调查当地公民和政治家对沃尔夫斯堡项目潜在环境和社会经济影响的看法。我们采用跨学科的政治地质学方法,根据欧洲围绕所谓“绿色开采主义”的辩论,评估其地质可行性、社会可接受性和相关的权力关系。结果从地质角度来看,该锂矿床的开发前景很好:Weinebene硬岩脉状锂辉石矿床被评估为1290 Mt, Li2O品位为1%,计划矿山可提供10,500 toh /年,为期20年,约占2021年全球产量的4.5%。然而,该研究的主要结果表明,冲突正在围绕当地环境影响出现,例如交通的增加。这种导致二氧化碳排放量增加的环境影响与脱碳目标和生态转型相矛盾。当地青年和政治家强调了当地矿产生产、创造就业机会和经济发展的可能性。尽管如此,政界人士还是批评了该公司的沟通政策。结论地质分析表明该区锂资源充足。否则,沃尔夫斯堡项目就会因缺乏对其未来的公开对话而受到破坏。当地居民和政治家很少参与规划和许可阶段。欧洲锂公司有信心很快开始开采,但实际上这仍不确定。更广泛地说,我们的研究结果表明,需要一个强有力的去增长战略,以普遍减少欧洲的矿物消费,同时停止全球南方的破坏性采矿项目。当谈到欧洲“后院”锂开采的未来时,必须更多地考虑当地公众的看法。需要建立机制,使当地居民充分参与决策过程。
