While these policies are commendable, and are indeed attracting many private investors, existing studies document how social and environmental justice concerns are often overlooked—sometimes causing local contestations against energy projects. However, to date, there has been less attention given to cases where procedural justice elements (e.g., access to information, access to meaningful participation, access to justice, and respect for local culture) led to a successful land negotiation for energy development without outright conflict. Using a case study in Kenya, this article aims to bridge this gap by showing how a fair application of various elements of procedural justice in land consultation has facilitated the establishment of the Kipeto wind farm. This qualitative research is based on semi-structured interviews that took place from February to March 2023, with a follow-up visit in December the same year, supplemented with review of secondary data sources.</p><h3>Results</h3><p>The results indicate that for energy projects to be accommodated in and by communities, access to land must be properly negotiated, particularly with the actual landowners whose livelihoods are most likely to be implicated by the project. Second, local people’s perception of what they regard as a <i>‘just’</i> or ‘<i>fair</i>’ process of land consultation constitutes the basis for their acquiescence and compliance.</p><h3>Conclusion</h3><p>Ensuring a ‘just’ procedure in land consultation with the actual landowners is a key strategy to avoid conflicts. Land investors, governments, and policy-makers who interface and negotiate with communities must ensure the provision of procedural justice, particularly in contexts where local livelihood is tied to land and where land is individually owned. Although the findings suggest a positive case of wind energy development in Kenya, the project is barely 4 years old; things may change overtime if agreed conditions are not met as specified in the MoU. Therefore, additional follow-up research is needed to ascertain the extent to which both KEL and landowners live up to their promises.</p></div>","PeriodicalId":539,"journal":{"name":"Energy, Sustainability and Society","volume":"14 1","pages":""},"PeriodicalIF":4.6,"publicationDate":"2024-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://energsustainsoc.biomedcentral.com/counter/pdf/10.1186/s13705-024-00482-z","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141884060","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In both academic literature and non-academic discourse concerning the energy transition, resilience is frequently mentioned as an additional objective or requirement. Despite its frequent use, resilience is a very malleable term with different meanings in different contexts.</p><h3>Main text</h3><p>This paper seeks to identify how resilience is understood in the field of the energy system and whether there are similar aspects in the different ways the term is understood. To this end, we review more than 130 papers for definitions of energy system resilience. In addition, we use different aspects to categorize and examine these. The results paint a diverse picture in terms of the definition and understanding of resilience in the energy system. However, a few definition archetypes can be identified. The first uses a straightforward approach, in which the energy system has one clearly defined equilibrium state. Here, resilience is defined in relation to the response of the energy system to a disturbance and its ability to quickly return to its equilibrium. The second type of resilience allows for different equilibriums, to which a resilient energy system can move after a disruption. Another type of resilience focuses more on the process and the actions of the system in response to disruption. Here, resilience is defined as the ability of the system to adapt and change. In the papers reviewed, we find that the operational definition of resilience often encompasses aspects of different archetypes. This diversity shows that resilience is a versatile concept with different elements.</p><h3>Conclusions</h3><p>With this paper, we aim to provide insight into how the understanding of resilience for the energy system differs depending on which aspect of the energy system is studied, and which elements might be necessary for different understandings of resilience. We conclude by providing information and recommendations on the potential usage of the term energy system resilience based on our lessons learned.</p></div>","PeriodicalId":539,"journal":{"name":"Energy, Sustainability and Society","volume":"14 1","pages":""},"PeriodicalIF":4.6,"publicationDate":"2024-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://energsustainsoc.biomedcentral.com/counter/pdf/10.1186/s13705-024-00478-9","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141865322","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These conditions present trade-off challenges between higher sustainability requirements, maintaining production capacity and new revenue opportunities. Optimization methods, such as linear programming (LP), are essential for determining the ideal substrate mixture and profitable solutions amidst multiple market conditions, plant-specific process constraints, and substrate properties.</p><h3>Methods</h3><p>We updated a substrate mixture optimization model within an assessment framework for the repowering of existing biogas plants (BGPs), which focuses on the operator’s perspective. By integrating multiple German biomethane markets for various BGPs, we assessed changes in the substrate mixture, GHG emissions, contribution margins, and constraint parameters to derive conclusions for operators and future framework design.</p><h3>Results</h3><p>Integrating market revenues and constraints can increase contribution margins by 12–55%. Additional gains can be achieved by considering multiple markets simultaneously but limited to a few BGPs. The plant-specific LP solution space and used benchmark market are decisive. The former limits the potential of high substrate-specific contribution margins, which has a significantly higher impact than the relation between plant-specific characteristics and process constraints. The advanced fuel market is currently the lead market for biomethane, incentivizing GHG-emission extensive substrates, decreasing gas production and GHG emissions but increasing levelized cost of energy (LCOE) and partially CO<sub>2</sub> abatement costs.</p><h3>Conclusions</h3><p>The key to improve profitability and to supply an increasing biomethane demand while fulfilling new requirements is a large LP solution space. Increasing market options, substrate availability, and digestion system capacity achieve this on the operator’s side. Policy makers could reduce normative requirements such as the maize cap or double counting of advanced fuels and favor high but uniform GHG requirements. Operators can prepare robustly for the future substrate mixture by adding digester volume and pre-treatment tech, ensuring long-term and diverse substrate availability, and contracts with flexible components. Although current market conditions can improve specific GHG emissions, they do not necessarily increase manure usage when other options, such as straw, are viable.

Policy measures directed at reducing car traffic in particular are often met with indifference and resistance.

However, their realisation is contingent upon framework conditions and policy settings, which are often included in accompanying narrative scenarios. This paper therefore proposes refocussing the model-policy logic towards directly modelling policy effects. Applying this approach to the case of German passenger transport, I focus on demand-side policies and use open-source databases and models to develop a module for the translation of policies into model parameters.</p><h3>Results</h3><p>Separate model runs were used to test a ceteris paribus policy reference scenario for 2035, the marginal impacts of modelled single policy effects, and a joint policy package scenario. Relative to the reference, demand-side policies show significant impacts: an annual reduction of 355 bn person-kilometres (30%) and a reduction of car-owning households from 95 to 90% in rural areas and from 76 to 64% in urban areas. The resulting mode shift decreases car-driven kilometres by 400 bn and increases public transport by 45 bn per year. This may reduce GHG emissions by an additional 30 Mt (or 33%) relative to the reference in 2035.</p><h3>Conclusions</h3><p>Transport demand policies can significantly mitigate GHG, calling for a stronger policy focus beyond the much-studied shift to electric vehicles. While further research and model development are needed, the feasibility of policy scenario modelling increases its utility for policy-making.</p></div>","PeriodicalId":539,"journal":{"name":"Energy, Sustainability and Society","volume":"14 1","pages":""},"PeriodicalIF":4.9,"publicationDate":"2024-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://energsustainsoc.biomedcentral.com/counter/pdf/10.1186/s13705-024-00467-y","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141430147","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
