The aim of this study is to demonstrante Estonian Energy Roadmap 2040 modelling process, taking into account energy consumption in accordance with the expectation and improvement of the living standard. In the frame of this study the evaluation of the possibility for Estonian Energy sector to become carbon neutral by 2040 have been presented. The roadmap to climate neutrality models three sectors: electricity, heating / cooling and transport together, aiming at reducing overall energy consumption, sustainability, security of national supply and the implementation of balanced economic principles. Balanced economic principles in this case mean high resource efficiency and reduced ammount of subsidies. Results of modelling show dnergy demand, energy mix and carbon emissions for these sectors in 2030 and 2040 and are compared with these indicators in 2021.The study estimates the amount of investment required to achieve carbon neutrality of Estonian energy sector. In assessing the future economy, the total environmental impact of activities, the preservation of the well-being of the Estonian population and economic reasonableness are examined in parallel with traditional economic indicators.

This paper explores the correlation between respondents concerns regarding climate change, their eagerness to adopt an AFV and their responsiveness to incentives. Seen as the solution for a cleaner mobility and greenhouse gas reduction in urban areas globally, alternative fuel vehicles (AFV) still own a modest market share in Europe. Among many reasons, the purchase price seems to be one of the most challenging to overcome. Incentives are considered a solution to mitigate the price barrier. The results of a survey carried out by the authors to 444 respondents led the authors to conclude that participants agree that AFVs contribute to tackle climate change. They also deduced that the vehicles price represents an offside for the lower-income households. Furthermore, the study revealed that the latter are less prone to buy an alternative fuel vehicle than higher-income families (59% against 80%). The authors also inferred that generally, households are more receptive to incentives or benefits based on up-front discounts or exemptions, directly impacting price and immediate savings, such as taxes exemption (value added tax and circulation tax), fuel discounts and purchase incentives. However, some differences were observed between income segments. For instance, the reduction or exemption of loan interests is among the most popular incentives for lower revenues, whilst higher revenues favour scrappage and non-financial incentives. Finally, in line with other studies, as upper incomes are less dependent on incentives and benefits to carry out the purchase, the authors put forward a differential and progressive approach for incentive instruments targeting lower revenues, allowing broader and equitable access to low carbon technology.

Knowledge about the demand of renewable thermal energy is essential for the integrated planning of sustainable cities. Planners and decision-makers need high-quality and comprehensive data for rapid and decisive action. However, little to no corresponding information is available for the status quo or possible development scenarios. Thus, new methods for urban building energy modelling and simulation with high resolution and accuracy are needed. In this paper, we present the research we conducted on the thermal energy demand of a city district in Graz, Austria. We developed a novel bottom-up, white box, multi-tool workflow for performing large-scale and high-resolution modelling, simulation and analysis of urban buildings in different development scenarios. We calculated the demand for heating, cooling and hot water in full-year dynamic building simulations and assessed the results quantitatively and spatially. Our results in the Scenario 2050 show that despite massive densification of the building stock by 88%, the calculated heat energy demand rises only by 4%; while the cooling demand soars by 432%. All results are available as hourly mean values and annual totals and in easy-to-understand spatial map representations, thus supporting stakeholders to meet the net-zero CO2-equivalent emission targets of Graz.

This paper examines a Renewable Energy Community (REC) made up of 10 dwellings that collectively self-consume energy produced by a photovoltaic field connected to a water purifier. Each dwelling heat demand is satisfied by means of Heat Pump (HP) coupled with Thermal Energy Storage (TES), which can be managed to perform load shifting and increase collective-self-consumption (CSC). Techno-economic analyses are performed accounting for HPs' COP variation with temperature and part load operations, as well as TES heat dispersion. A new centralised control strategy for HPs is proposed and a sensitivity analysis is performed to assess the impact of varying TES system capacity. The results show that the centralised strategy can increase the CSC by 12-30%, with TES sizes of 100-1000 litres respectively. But the electricity consumption of HPs increases by 2-5% due to higher storage system temperatures causing worse average COPs by 2.3-0.6% and higher thermal losses by 29-58%. As a result, REC's energy independence rise, as does the amount of CSC incentives, but electricity bills also increase. Comparing these trends shows that CSC incentives should be adjusted according to energy prices to ensure cost-effective outcomes for all stakeholders and encourage the adoption of similar centralised control strategies.

This paper draws on three recent case studies which have shown encouraging economic results in meeting net zero carbon emissions targets through Smart Local Energy Systems (SLES) in different localities across England, based on the GreenSCIES model. The blueprint for the GreenSCIES SLES was developed in Islington, London, and consists of a 5th generation ambient loop district heat network using wasteheat from a large data centre, and includes electric vehicle charging, storage and solar PV. This allows for heat sharing between buildings and applications for heat recovery from local sources. In Sandwell, Birmingham, where the heating demand is nearly ten times higher than the cooling demand the design is based on a 4th generation heat network with wasteheat from a local metal foundry and some cooling supply and heat storage in the aquifer. A study in Barnsley, Sheffield, explored wasteheat from a local glass factory and considered mine workings for providing seasonal storage of heat for resilience to a single source industry. This scheme could be further expanded, increasing the available carbon emissions savings. These examples provide feasible and economic SLES projects demonstrating the importance of collaboration between researchers, local government and industry. They also illustrate adaptations of the original GreenSCIES concept providing pathways towards net zero carbon for a diverse range of urban locations with different housing density and waste heat sources.

The EU is succeeding in the achievement of climate and energy targets, but affordability of energy services cannot be left behind. The paper assesses the interlinkages between SDG 7’s social, economic and environmental dimensions to understand whether they go hand in hand or back to back. With Eurostat data for 27 countries for the share of households unable to keep homes warm, energy dependency and the share of renewables, we use correlations and scatter (for pairs) and the Venn diagram (for the combination of the three). Results show a diversity of synergistic or trade-off paths, making clear that the solutions to improve the progress in SDG 7 cannot be the same for all Member States and that even the most urgent measures in a domain should not compromise advancements in others. The micro affordability ratios computed and the share of households with affordability problems expose a greater extension of issues than those revealed by EU affordability indicator, confirming the relevance of looking at the problem from different lenses. Moreover, households with elder and living in more isolated areas are found especially prevalent among those with affordability problems. This should be accommodated in policy measures to support those most in need.

This paper aims to present an approach for the planning of carbon low heat supply in a future district heating system based on open data for German cities with existing district heating networks. One focus is on the integration of industrial waste heat and the uncertainty of future waste heat sources as well as restrictions on the use of biomass. For that purpose, knowledge about the energy demand is necessary. In a first step it is shown how the demand around a heating network is estimated with spatial data and a load profile is generated. Local available heat sources are examined according to their suitability and their kind of integration in the heating network. As heat production from different units are optimised, the development of a simulation model will be presented. The simulation is based on the optimisation of the operational costs of the used technologies for heating supply. Different scenarios covering various technologies and economic assumptions are applied. The results show the levelized costs of heating as well as the ecological performance. A sensitivity analysis shows the importance of uncertainties for the economic assumptions. The results showing levelized costs of heating as well as the ecological performance underlining the advantage of excess heat integration.

At the local level, energy communities are at the forefront of the European Green Deal strategy offering new opportunities for citizens to get actively involved in energy markets. The scope of this study is to propose a multi-objective optimization framework to minimize both carbon dioxide emissions and total annual costs in an energy community, considering, within different constraints, a wide availability of decision variables including local renewable energy sources, sector coupling, storage and hydrogen. The methodology involves the coupling of the software EnergyPLAN with a multi-objective evolutionary algorithm, considering 2030 and 2050 as target years and modelling a set of eight types of scenarios, each consisting of 100 optimal systems out of 10,000. The case study is an energy community in the European Alps. The results show, on the one hand, the key role of sector coupling technologies such as cogeneration, heat pumps and electric vehicles in exploiting local renewable energy sources and, on the other hand, the higher costs in introducing both electricity storage to achieve a complete decarbonisation and hydrogen as an alternative strategy in the electricity, thermal and transport sectors.

Energy communities are widely studied from various perspectives, especially in the context of geopolitical events of recent years, when humanity is faced with the need for urgent solutions to promote climate change and alleviate the crisis of energy resources. Although citizens' interest in the use of renewable resources has gradually grown, energy policy support measures for more active participation of society in the implementation of energy efficiency measures are still being implemented with variable success, especially through mutual agreement. Serious games are a rapidly growing tool for awareness and collaboration on a single platform for gamers seeking solutions to energy resource optimization issues. The paper focuses on energy community versus energy use practices, trends, and intervention strategies in multifamily residential blocks, using serious gaming and direct user online feedback. This study uses a multi-player simulation tool to enable the modelling of scenarios for energy efficiency measures for apartment building block residents and energy community target goals for decision-making decisions. User experience and game mechanics were tested on a pre-selected group. The results indicate positive feedback, including a practical application for both energy community and professionals, and provide valuable recommendations for further research and improvement of the tool.

Following decades’ of energy systems interventions, there has been growing concerns about the impact of historical interventions on-the-ground and how they shape changes in energy systems. Who are the key actors and how have they shaped historical energy systems interventions? In this study, an analysis of stakeholders in Nigeria’s electricity sector through a social network mapping lens was conducted. First, a stakeholder mapping based on an interest-influence matrix that shows the degree of various stakeholder interest and influence in shaping decisions and interventions in both centralized and decentralized electricity systems was developed. Secondly, a stakeholder network grid that shows the relations between the various stakeholders (who knows whom) was developed. The study reveals that there are stronger network relations among stakeholders involved in issues and decisions on centralized electricity grid infrastructure which is influenced by the presence of stronger regulations/regulatory instruments. However, these stakeholder relations are weaker in decentralized electricity systems due to less stringent regulations in the decentralized electricity space. The study concludes by highlighting the impact of the stakeholder relations and the interest-influence tussle on the future of electricity systems development in Nigeria.
