This issue presents some of the latest findings within energy planning research and form a special issue from the 2021 5th Annual Conference of the Portuguese Association of Energy Economics as well as for the 2020 Sustainable Development of Energy, Waste and Environmental Systems conference series. The work presented probes into the effects of the European emissions’ trading system on innovation, and the development of the Chinese wind power industry. Notable is also an analysis of people at Portuguese universities revealing lesser knowledge of renewable energy technologies but a more positive attitude towards this among women – and vice versa among men. EnergyPLAN-based energy systems analyses with cases from Iran and Serbia are presented, and different indicators for energy systems analyses are deliberated in a Mexican context. Marine energy developments in Columbia, the United Kingdom, Canada and Denmark are discussed with a focus on siting and barriers. Also, barriers against solar energy exploitation in Indonesia are explored as are barriers against energy savings in Nigeria.

Just in the immediate neighborhood of European Union (EU), Republic of Serbia as one of Western Balkan (WB) countries is lagging behind in the energy transition regardless technological advances and policy instruments available. EU created a momentum for the energy transition acceleration with the European Green Deal, which is forwarded to the WB through the Energy Community secretariat as Green agenda and in general, the response in the form of National Energy and Climate Plans (NECPs) is expected in the short to midterm. Republic of Serbia’s Low Carbon Development Strategy with Action plan (LEDS) and current Energy Strategy will be analyzed, commented and improvements suggested for the acceleration of the energy transition, based on the newest findings from the simulation-based optimization techniques using the sectors coupling approach. Furthermore, integrated assessment modeling (IAM) techniques, exploring the climate and energy cross impacts with the more details will be included. The purpose of the research is to provide the decision makers in Serbia with the best available insights regarding sustainable energy systems planning tools, possible shortcuts for delayed planning activities and Serbians with better chance to benefit from adoption of these strategies in faster transition.
就在欧盟(EU)的近邻，塞尔维亚共和国作为西巴尔干(WB)国家之一，无论技术进步和政策工具如何，它在能源转型方面都落后于欧盟。欧盟通过《欧洲绿色协议》(European Green Deal)为加速能源转型创造了势头，该协议通过能源共同体秘书处作为绿色议程提交给世界银行，总体而言，预计将在中短期内以国家能源和气候计划(NECPs)的形式作出回应。基于使用部门耦合方法的基于模拟的优化技术的最新发现，将分析、评论塞尔维亚共和国的低碳发展战略与行动计划(led)和当前的能源战略，并提出加快能源转型的改进建议。此外，将包括综合评估模型(IAM)技术，探索气候和能源交叉影响的更多细节。这项研究的目的是为塞尔维亚的决策者提供关于可持续能源系统规划工具的最佳见解，为延迟的规划活动提供可能的捷径，并使塞尔维亚人有更好的机会在更快的过渡中采用这些战略。

Countries with emerging economies face a significant challenge when developing strategies to move towards a low emission energy system and keep their economies growing. The power System plays a crucial role in these strategies and by the correct measurement of its sustainability is possible to identify which alternative improves sustainability the most. This article proposes indicators for the evaluation and assessment of the sustainability of Mexican Power System planning scenarios put forward by two government administrations with a study horizon to 2030. The scenarios are characterized by the program of additions and retirements of generating capacity along the period of 2019 to 2030, and eventually, optimal dispatch was obtained to accomplish the hourly demand. Sustainability indicators were developed and calculated to evaluate the energy security, energy equity and environmental sustainability dimensions. Subsequently the indicators were fed to the Position Vector of Minimum Regret Analysis as multicriteria decision analysis. By analysing the results, it is highlighted that the expansion of power grid capacity, as well as the hourly availability of hydro plants improve the sustainability of the Mexican Power System. The comparison between both scenarios’ performance, based on the Energy Trilemma, indicates that the current government’s planning is slightly more sustainable.

Despite high expectations for the sector, most marine energy technologies remain in the research and development, or at best demonstration, phase. The industry is in a period of stagnation, and requires new approaches to overcome the challenges that inhibit widespread deployment. Small-scale initiatives have proven to be a successful means of developing other renewable technologies but their role in supporting marine energy is not well researched. This paper provides a review of the barriers and opportunities presented by different policy landscapes, financial support mechanisms, markets, key actors, and wider regulatory and governance issues. Semi-structured interviews with marine energy stakeholders from the UK, Canada and Denmark were used to explore the role of small-scale marine energy projects, and were supplemented by interviews with the general public in England. This showed that while marine energy is appropriately scalable for local projects, financing remains a major hurdle. Discretionary local authority finance, as well as other novel options such as crowdfunding, tends to be relatively modest, supporting the argument for small-scale projects. A market for smaller devices exists, particularly for remote communities currently dependent on expensive energy from oil-fired generators. There remains a significant role for small-scale projects in testing the technology, contributing to reductions in cost and environmental risk. Current processes for environmental impact assessment can present a significant hurdle for small projects, but proportionate, adaptive assessments are evolving. Finally, community ownership and public participation have the potential to increase advocacy for the industry, with multi-actor partnerships presenting a positive way forward.

The Chinese energy transition, as a shift from fossil fuels to renewable energy sources, involves the dynamic growth of wind power’s importance in a national energy mix. The development of the wind power industry in this country is intertwined with the implemented policies that translated to the significant increase in energy generation from this power source and the growth of trade volumes of wind power products. This research aims to review and analyse the China's policy that impacted wind power development in 2000-2019. The author aims to evaluate the efficiency of implemented policies and strategies from the perspective of the new structural economics assumptions and the revealed comparative advantage of the Chinese wind energy products. In addition to the review of scientific literature and policy documents, as well as analysis of the relevant trade and energy indicators, the method applied in this research is a calculation of the Revealed Comparative Advantage (RCA) index. The results provide pieces of evidence that despite the substantial development of the Chinese wind power industry on a national scale, this country still has not revealed a comparative advantage globally. However, the results also suggest that the Chinese wind power industry is on the right track to achieve export specialisation soon. Furthermore, the China's policy for wind power development matches the new structural economics assumptions. The presented insight into studied industry blazes the trail for other countries, which consider following the Chinese development path by shaping the growth of leading-edge industries and the energy transition process throughout various state interventions.

Energy literacy is seen as one of the most powerful tools, available to ordinary people, to contribute to a more sustainable world. Since women tend to be considered the main caregivers, due to their maternal instinct, being generally more attentive, more altruistic, and more concerned with the future of their children, are women more involved in the transition to a more sustainable future? To answer this question, we seek to assess the literacy levels of Portuguese university members and explore the differences between men and women. Using the Heteroskedastic Ordered Probit, we found that women tend to have lower levels of knowledge about energy, but a more positive and sustainable attitude and behavior.

District heating systems have a great potential for supporting the energy transition towards a renewa-ble energy system, and could also be an option in less dense populated urban districts and rural communities with a medium heat density. In these cases, distributed thermal energy storages at each building could improve the overall system performance by enabling a leaner sizing of the piping sys-tems due to peak-shaving and reducing the heat losses of the distribution grid. But how can distribut-ed storages already be considered within the design of the district heating network itself? And what are the quantitative benefits with respect to the district heating piping system? This paper answers these questions and presents an open-source optimisation approach for designing the piping network of a district heating system. This includes the optimisation of the network topology, the dimensioning of the pipes, and the consideration of distributed storage options. A linear mixed-integer program-ming model with a high spatial resolution including heat storages at each customer has been imple-mented. Within the QUARREE100 project, the approach is demonstrated on a real world case of an existing district with 129 houses in the provincial town Heide in Northern Germany. In the scenario with 1 m³ heat storages, the thermal losses of the district heating network can be reduced by 10.2 % and the total costs by 13.1 %.

Small-scale development of renewable energy has been identified as one possible solution to meet future energy needs and is well aligned with the general European trend towards further development of community energy projects. Increased local energy production will move energy plants closer to habitation, placing aspects related to social acceptance at the center stage [1, 2]. Until recently, small hydro power [3] projects in Norway have been owned by local farmers and others with property rights to rivers. As the profitability of these projects has decreased, international investors have taken interest in SHP projects as part of their long-term investment strategy. In this paper, we study what influences social acceptance of SHP projects in Norway based on interviews and qualitative data from different SHP projects in Norway. We find that community energy projects often are attributed positive qualities when ownership is local. Thus, we argue that there is a need to consider more thoroughly how to organize ownership of small-scale renewables in the future, if it is to uphold its position as a popular and viable solution to meet future energy needs [3].

This research analyzes the changes to electricity generation and demand in Japan following both the Global Financial Crisis and Disaster of March 2011. Monthly electricity demand and generation data for all regions of Japan from April 2005 to March 2016 were reviewed to identify differences in disruption-response between different types of electricity users. We apply inferential statistics to identify underlying trends, which we find are dominated by differences in user scale response. Higher capacity users reduced demand in response to the Global Financial Crisis, whereas smaller domestic scale users reduced electricity demand after the Disaster. Analysis reveals that regions within the 50Hz grid that were directly impacted by the Fukushima event and resulting load restrictions showed a statistically significant sustained reduction in monthly electricity demand post-disaster. However, Kansai and Shikoku, regions that are both outside the area directly impacted by the Fukushima event, also showed the same sorts of sustained significant reductions. By considering two disruptions to the same sociotechnical system we can draw conclusions that add to the discourse of electricity use behaviors, which informs both disaster response planning and policy for the broader issues of electricity demand reduction for climate stabilisation. In particular, the results highlight the importance of tailoring engagement and intervention actions to the preferences and needs of different types of electricity users.

To combine a variety of different heat generating technologies, static design methods will not be sufficient to design future heat supply systems. New energy system design approaches are being developed with consideration of fluctuating renewable energy sources, different subsidy measures, as well as CO2-emission reduction targets. The motive of this study is to develop a new methodology to design and optimise an energy system considering these constraints. The methodology is developed based on the Open Energy Modelling Framework (oemof) and applied on a sub-urban region in northern Germany. Local specifics of energy source potentials are taken into account. It adapts the boundary conditions of a German federal funding program for innovative heat supply networks “Heating Network Systems 4.0.” Federal funding restrictions of combined heat and power systems and self-consumption are also considered. An economic optimisation was conducted considering a variety of energy sources. Cost optimal energy system design was computed regarding investments costs, energy prices and annual CO2-emission restrictions. The integration of combined heat and power (CHP), photovoltaic (PV) and heat pump (HP) systems in combination with storage size optimisation can reduce CO2-emission of heat production by approx. 69% compared to the current state of heat production.
