Modern district heating (DH) systems are one of the most promising heat supply solutions to reach the goal of fully decarbonised energy systems. The research goal of this paper is to evaluate the impact of installation of individual metering in DH systems on energy savings and emission reduction by application of machine learning algorithms and to predict how would this particular system upgrade measure influence the energy consumption and emissions. The research is focused on DH systems in Croatia. The results showed that dominant variable is the installation rate of individual metering devices (i.e. heat cost allocators - HCAs) and, for maximum energy saving, it should strive to 100% within a building. In that case, decrease in annual specific heat consumption in average building connected to a district heating system in Croatia is expected above 40 kWh/m2. Developed regression models show that apartments with installed HCAs could achieve about 40% reduction in heat consumption, compared to the apartments without HCAs.

The COVID-19 and the resulting global energy crises highlighted the importance of decarbonization and the necessity of shifting the economy from fossil fuels towards renewable energy sources. Sustainable energy transition is also a key element of circular economy, social welfare and justice. In this paper we developed an indicator set and we compiled a composite indicator to measure the performance of the EU Member States regarding the sustainable energy transition between 2007 and 2019. Our results show significant differences which do not follow the usual East-West division of the integration. Both convergence and divergence can be revealed.

In the next ten years, the Baltic countries ― Estonia, Latvia, and Lithuania ― are planning large investments in renewable power generation and transfer capacity, substantial phase-out of fossil-based power generation, and desynchronization from the Russian electricity grid. In this article, the operational impacts of these changes on the Baltic energy system from 2017 to 2030 are studied with an open-source Backbone energy system model. The operation of Estonian, Latvian and Lithuanian power and heat, transport, and building sectors are optimized simultaneously on an hourly level, and results are analysed with operational, environmental, economic, and security indicators. Results suggest that the planned transition would support Baltic targets in renewable generation (from 45% to 92%) and self-reliance (2.3 TWh increase in domestic power generation and 5.5 TWh decrease in natural gas imports) with a moderate impact on system costs. However, an increase in transport CO2 emissions could risk national non-ETS targets. The hourly operation of the system, with a high share of wind and solar, is based on active use of storages and interconnectors. Model results raise concerns about the amount of Estonian dispatchable capacity, the commercial feasibility of Latvian natural gas CHP’s, and the high ramping rates of Lithuanian interconnectors.

The planning procedure for district cooling as an urban system was presented and carried out using the example of the Tallinn city centre. The following steps were described in detail: cooling demand determination, cooling generation planning and cooling transition analysis. Based on the three proposed methods (average specific cooling load, satellite imagery analysis of a specific building, counting the number of fans in dry coolers and the combination method), the cooling capacity of the evaluated district was estimated at 63.2 MW. In terms of cooling generation, the analysis shows that seawater for free cooling can cover up to 55% of the annual cooling consumption. Electric chillers and absorption chillers that use surplus heat can cover the rest of the district cooling demand. The district cooling network was designed for three scenarios: with one generating unit, with two generating units and a looped network. Despite the fact that the looped network is the most expensive option, this type of solution is considered feasible as it will make it easier to connect new consumers.

This 34th volume of the International Journal of Sustainable Energy Planning and Management includes papers from the 2021 conference on Sustainable Development of Energy, Water and Environmental Systems (SDEWES) held October 10-15, 2021, in Dubrovnik, Croatia as well as the 7th International Conference on Smart Energy Systems held September 21-22 in Copenhagen, Denmark and two normal papers. A focus area of this issue is district heating and district cooling systems, with articles addressing resources for district heating and cooling systems, impacts of having individual district heating metres for consumers and approaches to analysing district heating systems. Another focus area is stakeholder involvement where two groups of researchers focus on stakeholders from an energy island perspective as well as from a positive energy district perspective. Both groups note the importance of factoring in stakeholders when devising transition plans. Plans for increasing the penetration of renewable energy sources for the Estonian, Latvia and Lithuanian systems are analysed using the Backbone model, finding modest increases in system costs. Lastly, an article sets up an indicator system for assessing environmental performance of European Union member states ranking, e.g., Estonian, Latvia and Lithuanian as moderate (Estonia and Latvia) to weak (Lithuania) in terms of sustainable energy performance score, based on 2019 data.

Geographic information system (GIS) software has been essential for visualising and determining heating and cooling requirements, sources of industrial excess heat, natural bodies of water, and municipalities. Policymakers highly encourage the use of GIS software at all administrative levels. It is expected that the heating and cooling demand will continue to increase. For a reliable heat and cooling supply, we must identify heat sources that can be used to provide heat or for removing surplus heat. We propose a method for identifying possible heat sources for large heat pumps and chillers that combines geospatial data from administrative units, industrial facilities, and natural bodies of water. Temperatures, capacities, heat source availability, as well as their proximity to areas with high demand density for heating and cooling were considered. This method was used for Estonia, Latvia and Lithuania. Excess heat from heat generation plants and industries, sewage water treatment plants, and natural heat sources such as rivers, lakes and seawater were included. The study’s findings provide an overview of possible industrial and natural heat sources, as well as their characteristics. The potential of the heat sources was analysed, quantified, and then compared to the areas of heating and cooling demand.

Utilization of landfill gas for electricity generation should be an attractive option for Ukraine in light of the country’s rapidly growing municipal solid waste problem, the influx of intermittent renewable electricity into the national grid, and renewable energy adoption commitments. However, the deployment of landfill gas power plants has been slow vis-à-vis other alternative energy technologies despite the existing government incentives. This article aims to help understanding this trend by investigating the economic feasibility of landfill gas power plants. The research focuses on determining the Levelized Cost of Electricity of these electricity generation facilities and comparing it to the feed-in tariff available to landfill gas electricity producers. The results show making an investment into a landfill gas-fired power plant is an appealing strategy due to a potential high and quick return on investment at 5.1 years. This leads to the ultimate conclusion that economic feasibility is not a cause for the slow adoption of landfill gas as a source of renewable electricity generation in Ukraine. In addition, the article identifies several potential barriers to landfill gas electricity generation deployment to be investigated in future research.

Abstract Global energy demand is increased due to industrial development. Currently, fossil fuels, with more than 85%, are the most prominent source of energy in Iran, and their consumption has been raised, but it has destructive impacts on the environment and human health. This study aims to model and techno-economically assess renewable energy heating for replacing natural gas in Qazvin city. The natural gas domestic demand was quantified, followed by consumption forecasting for 15 years. Six different scenarios were investigated to assess renewables’ potential to meet the city heat demand for the next 15years. The study uncovers that the best practice scenario can reduce natural gas consumption and increase renewable energies share. Finally, the proposed scenario was analyzed economically and environmentally. Results revealed that the return on investment would occur in 3 years by exporting the saved natural gas. Also, Iran can reduce CO2 emissions by about 1 million tons by the year 2029.

Energy conservation is an all-encompassing principle (building economics, behavioural, technological and educational) whose cumulative effects can result to improvement in energy access, energy availability and sufficiency, quality of life and retractive impacts on climate change and reduction in carbon footprint of a country. With the current global realities of COVID-19 pandemic, energy conservation has become one of the systemic resilience strategies necessary to manage dwindling energy supplies and financial shocks. However, as simplistic as it sounds, energy conservation as a behaviour of household consumers is a complex phenomenon that has persisted throughout the century. While strategic policies and long-term planning have promoted and re-orient consumers in some developed and developing countries towards energy conservation behaviour, there is no paradigm shift from energy wastage to energy conservation among consumers in Nigeria’s residential sector. This paper therefore discusses the factors that constrains energy conservation among household electricity consumers, unearths precursors and enablers of energy conservation with peculiar appeal to Nigeria. Policy implications and strategies of entrenching energy conservation culture are also outlined.

The offshore wind energy sector is showing a growing interest because the increment of global energy demand and the commitment to reduce the CO2 emissions. The need to identify new wind offshore areas have motivated the development of methods where several quantitative and qualitative factors are considered. Then, this study reviewed these factors to establish a priority order to know when they could be analyzed within 3 main stages (pre-feasibility, feasibility and final decision). As a result, this research organized tha main factors in the 3 stages and performed a pre-feasibility analysis for assessing potential offshore areas considering technical-environmental features such as spatial classification, temporal variability (magnitude and direction) and geographical restrictions. The Colombian Caribbean coast was selected as study case, and 3 areas were identified according to their wind climate variability, in which 10 locations showed high potential for developing offshore wind projects. The north and central zone of the Colombian Caribbean coast were identified as the most suitable areas with mean annual wind-speed over 10 m/s with low magnitude and direction variability, two factors considered extremely important for the wind power generation.
