Limitations and opportunities of using Hotmaps online heat atlas in heat energy planning : a case study of a Hungarian rural area
No full textRationalising the production and use of thermal energy would be the key to energy transition. However, in most rural areas heat planning and just transition is challenging. Energy geography solutions such as innovative online heat atlases, like Hotmaps are valuable tools for estimating household heat demand at municipality level. The aim of this study was twofold, firstly to validate the Hotmaps database with the help of field-obtained actual consumption data and to determine its usability for local thermal energy planning. Secondly to develop and test a complex methodology supporting the definition of a heating energy mix in a highly diverse landscape and energy mix in a Hungarian rural study area facing coal phase-out. The results confirmed that settlements with residential heat demand above 5,000 MWh/a could rely on the Hotmaps, however, mapping the local heating energy mix can only be done by field data collection, especially where the ratio of the solid fuels is over 50%. The heating energy mix can vastly vary even within a small geographical area which underlines the importance of in-situ rural energy mapping and makes clear the need to develop such complex but replicable methodologies as this paper has
Charging facilities - Municipalities pave the way for accurate data: The Danish municipalities have taken the lead with data model, conceptual clarification, and collecting data from charging operators in a joint public database
No full textKommunerne ville skabe en ny normal for ladestanderdata i 2022. Der var brug for:
Transparens i et nyt marked, som var på vej mod kritisk infrastruktur
Gratis adgang – uden abonnement og apps
Ladestandere til biler, men også til mikromobilitet, for vi skal jo hellere cykle end køre bil
Forvaltningsdata af høj kvalitet, som kan genbruges til slutbrugerdata, fx i turismeapps
KL startede derfor i 2022 et dataprojekt, der skulle skabe de første standardiserede, fællesoffentlige ladestanderdata. Projektet er nu i mål og er gået i drift ultimo 2024.The Danish municipalities wanted to create a new normal for charging station data in 2022. There was a need for:
- Transparency in a new market that was moving towards critical infrastructure
- Free access – without subscriptions and apps
- Charging stations for cars, but also for micromobility, because we would rather cycle than drive cars
- High-quality administrative data that can be reused for end-user data, e.g. in tourism apps
KL therefore started a data project in 2022 that was to create the first standardized, public charging station data. The project is now completed and has been operational from the end of 2024
Tourists are flocking north – this requires more map data: More tourists are coming to Denmark, and tourism is becoming increasingly important for the municipalities' economy and jobs. At the same time, municipalities must take care of nature and avoid mass tourism. This requires more joint public tourism data.
No full textTurismeaktører arbejder ofte på tværs af kommuner, gerne i hele regioner eller endda på nationalt plan. Uanset størrelse og organisering har turismeaktørerne det til fælles, at de efterspørger standardiserede, pålidelige data om naturområder, infrastruktur, faciliteter og seværdigheder. Disse data anvendes til visualisering i apps, opslagsværker og i fysiske kort. Det er derfor en fordel, hvis data er standardiserede på tværs af kommuner, og let kan overføres regelmæssigt til deres webløsninger og apps.
Der har de seneste år været en stærkt stigende interesse for den fællesoffentlige, tværkommunale database, GeoFA (Geografiske Fagdata i GeoDanmark), som destination for kommunernes data. Adskillige nationale, regionale og lokale aktører bruger GeoFA, eller er i dialog med os om standardisering og registrering af flere og bedre data i GeoFA.Tourism actors often work across municipalities, often across entire regions, or even at national level. Regardless of size and organization, tourism actors have one thing in common: They demand standardized, reliable data about natural areas, infrastructure, facilities, and attractions. This data is used for visualization in apps, reference works and in physical maps. It is therefore an advantage if data is standardized across municipalities and can be easily transferred regularly to appropriate web solutions and apps.
In recent years, there has been a strong increase in interest in the joint public, cross-municipal database, GeoFA (Geographical Subject Data in GeoDanmark), as a destination for municipal data. Several national, regional, and local actors use GeoFA, or are in dialogue with us about standardizing and registering more and better data in GeoFA
Problem-based Intervention via Task-based Scenarios: Analysis of Practical Skills Acquisition Relations in Vocational Electrical Technology
Full text linkThe inability of vocational electrical technology (VET) students to transit from school-to-work after graduation shows that the practical skills needed for employability are far from being achieved. This has caused an increased unemployment rate among VET students. Hence, this study ascertained the relationships between problem-based intervention via tasks-based conduit wiring scenarios in VET students’ practical skills acquisition (PSA). Specifically, this study determined the sequential mediation effects of intrinsic motivation and ability beliefs on problem-based and practical skills acquisition relationship. A cross-sectional study design was adopted for the study. Data was collected from 78 VTE students that gave their consent to participate. The outcome revealed that problem-based intervention is a positive and significant predictor of VET students’ practical skills acquisition tasks. The result also revealed sequential mediating effects of intrinsic motivation and ability beliefs on problem-based and practical skills acquisition relations. This study is unique in that it examines how intrinsic motivation and ability beliefs sequentially mediate the link between problem-based interventions and the development of practical skills in vocational electrical technology (VET) students. By addressing the critical gap in employability skills through task-based conduit wiring scenarios, it provides novel insights into enhancing school-to-work transitions for VET graduates
A Strategic Plan for Renewable Energy Transition in a Coal Dependent Region using Participatory Backcasting: The Case of South Kalimantan Province in Indonesia
Full text linkIn this study participatory backcasting was refined to combine the use of existing visions in combination with stakeholder engagement and road-mapping and applied to the regional energy transition in Indonesia’s South Kalimantan Province, where the gross regional domestic product strongly depends on coal mining. Based on document analysis, interviews, consultations, and a focus group discussion, we determined necessary changes, driving factors and challenges, and co-created a roadmap towards the preferred Nett Zero Emission vision. The roadmap proposes: (1) to increase the capacity of renewable energy, particularly wind and solar, along with battery energy storage systems; (2) to transform economic activities currently based on coal towards bioenergy hubs and to build a regional economy based on renewable energy; (3) to enhance the quality of data on renewable energy potential, power grid flexibility, and variable renewable plants, and (4) to shift culture and behaviour towards energy saving, energy communities, electrification of lifestyles, and the use of renewable energy in industry. Our study contributes to the literature on participatory backcasting by a case on the clean energy transition in fossil fuel-rich nations in the Global South and advances backcasting by using existing visions instead of generating one or several new visions.

Ruteudvikling i luftfarten – Analyse af sociale faktorers betydning i en datadrevet branche : Artikel
Full text linkRuteudvikling fremstilles og italesættes oftest som en teknisk og økonomisk praksis, hvor fokus primært ligger på forecasting og finansielle beregninger. Denne artikel undersøger, hvilken rolle sociale aspekter spiller i udviklingen af flyruter. Der sættes særligt fokus på betydningen af netværk, relationer, tillid og møder gennem ruteudviklingsprocessen. Artiklens problemfelt er således at analysere, hvilken betydning sociale faktorer har i ruteudvikling og i forhold til deres samspil med de tekniske og økonomiske aspekter. Metodisk er artiklen opbygget som et casestudie, der undersøger ruteudviklingsprocessen for flyruten mellem Aalborg og New York. Den empiriske analyse baserer sig på interviews med centrale aktører, med det formål at belyse samspillet mellem sociale, tekniske og økonomiske dimensioner i processen. Denne empiri danner grundlag for en konceptualisering af en revideret forståelsesmodel for ruteudvikling. Artiklen konkluderer, at sociale faktorer spiller en væsentlig rolle i udviklingen af flyruter. Særligt fremhæves business-casens udvikling, som en iterativ proces mellem flyselskab og lufthavn. I denne tilgang aktiverer lufthavnen sit netværk og sine relationer for at synliggøre efterspørgslen efter nye ruter og dermed tiltrække flyselskaber
