Augmenting recent coverage of the topic of regional energy planning, this chapter introduces an Integrated Regional Energy Policy and Planning Framework (IREPP), which is conceptually comprehensive and also enhances feasibility of implementation. This framework contains important concepts of sustainable energy planning, including integrated resource planning, soft energy path, distributed generation using decentralized energy technologies, and energy-environment-economy-equity balance (E4). The IREPP also includes implementation feasibility analysis and highlights the importance of monitoring and evaluation. In the second part of this chapter, the IREPP is applied to the case of Jeju. Jeju's “Mid- and Long-Term Roadmap of Renewable Energy Planning” intends to promote renewable energy applications in order to build a carbon free energy system. This chapter evaluates Jeju's overall Roadmap via the lens of IREPP, assesses the rationale and feasibility of achieving its individual renewable target set for 2050, and, additionally, reviews progress made in some individual targets as of 2014.

Regional energy planning, which considers the unique pattern of local energy needs and local energy resources can be a tool to mitigate fossil fuel-triggered problems and enhance sustainability. Many researches underline the importance of regional energy planning but there exists some room for improvement in the planning approaches. This chapter introduces an Integrated Regional Energy Policy and Planning Framework (IREPP), which is conceptually comprehensive and also enhances feasibility of implementation. This framework contains important concepts of sustainable energy planning, including integrated resource planning, soft energy path, distributed generation using decentralized energy technologies, and energy-environment-economy-equity balance (E4). The IREPP also includes implementation feasibility analysis and highlights the importance of monitoring and evaluation. In the second part of this chapter, the IREPP is applied to the case of Jeju, the southernmost island of Korea. Jeju’s “Mid- and Long-Term Roadmap of Renewable Energy Planning” intends to promote renewable energy applications (a 50 percent target in 2050) in order to build a carbon free energy system. This study evaluates Jeju’s overall Roadmap via the lens of IREPP and also assesses the rational and feasibility of achieving its individual renewable target.

In recent years, most countries in the Middle East and North Africa (MENA), including Jordan, Morocco and Tunisia, have rolled out national policies with the goal of decarbonising their economies. Energy policy goals in these countries have been characterised by expanding the deployment of renewable energy technologies in the electricity mix in the medium term (i.e., until 2030). This tacitly signals a transformation of socio-technical systems by 2030 and beyond. Nevertheless, how these policy objectives actually translate into future scenarios that can also take into account a long-term perspective up to 2050 and correspond to local preferences remains largely understudied. This paper aims to fill this gap by identifying the most widely preferred long-term electricity scenarios for Jordan, Morocco and Tunisia. During a series of two-day workshops (one in each country), the research team, along with local stakeholders, adopted a participatory approach to develop multiple 2050 electricity scenarios, which enabled electricity pathways to be modelled using Renewable Energy Pathway Simulation System GIS (renpassG!S). We subsequently used the Analytical Hierarchy Process (AHP) within a Multi-Criteria Analysis (MCA) to capture local preferences. The empirical findings show that local stakeholders in all three countries preferred electricity scenarios mainly or even exclusively based on renewables. The findings demonstrate a clear preference for renewable energies and show that useful insights can be generated using participatory approaches to energy planning.

Abstract Integrating renewable energy technologies in a single system is becoming more reliable to meet electrical demand of remote locations. Here, integration and the optimal use of various available energy resources in a stand-alone microgrid are investigated. An integrated renewable energy system (IRES) approach has been proposed and analyzed using homer software. Seven scenarios with different combinations of energy sources and storage systems have been investigated based on their levelized cost of energy (LCOE) supply and net present cost (NPC). The proposed IRES, which includes photovoltaic (PV), wind, and biogas, gives the least LCOE as $0.207/kW h without any policy intervention. This LCOE reduces to $0.12/kW h with policy intervention and consideration of carbon abetment cost. Moreover, sensitivity analysis has been carried out with variation in load, solar radiation, and wind speed. The NPC is found to be most sensitive to the variation of load and least sensitive to the variation of wind speed.

The bioceanic Amazon corridor represents a development opportunity for the Peruvian and Brazilian economy but this economic evolution is linked to the production and use of energy. Energy is a conditioning factor of economic growth and development and the application of conventional (or alternative) energy systems is strongly influenced by both quantitative and qualitative trends in energy consumption. Decentralized production of energy is necessary, and new decentralized energy technologies based on renewable sources could provide additional income opportunities, decreasing environmental risk along Amazon corridor, and providing clean fuel and electricity. It’s necessary that the bioceanic Amazon corridors call for the application of energy systems related to the renewable local resources in coast, mountain and forest. In Peru, firewood is the principal energy source for cooking and heating and this fuel is used in inefficient combustion system that increases the impact on ecosystems. Typical Peruvian biomass source are wood, agricultural residues, agro industrial waste and municipal solid waste. The most obvious it’s the availability of agricultural and agro industrial residues that could be used as a biomass fuel source in modern plant to produce electricity. Today, there is a growing interest for ethanol production from sugar cane, but it couldn’t be applied along bioceanic corridors; therefore it is necessary to integrate other renewable sources.

Variable Renewable Energy Sources

Although it can be complex to integrate variable renewable energy sources such as wind power and photovoltaics into an energy system, the potential benefits are large, as it can help reduce fuel imports, balance the trade, and mitigate the negative impacts in terms of climate change. In order to try to integrate a very large share of variable renewable energy sources into the energy system, an integrated energy planning approach was used, including ice storage in the cooling sector, a smart charging option in the transport sector, and an excess capacity of reverse osmosis technology that was utilised in order to provide flexibility to the energy system. A unit commitment and economic dispatch tool (PLEXOS) was used, and the model was run with both 5 min and 1 h time resolutions. The case study was carried out for a typical Caribbean island nation, based on data derived from measured data from Aruba. The results showed that 78.1% of the final electricity demand in 2020 was met by variable renewable energy sources, having 1.0% of curtailed energy in the energy system. The total economic cost of the modelled energy system was similar to the current energy system, dominated by the fossil fuel imports. The results are relevant for many populated islands and island nations.

Exponential Population Growth

The exponential population growth will put great pressure on natural resources, agriculture, energy systems and waste production. New business models and innovative technological approaches are necessary to tackle these challenges and achieve the energy transition targets set by the European Commission. Renewable energy technologies and processes such as solar photovoltaic, solar thermal and anaerobic co-digestion have become a subject of interest and research as a solution that could be fully implemented in industries and solve several environmental and economic problems. This paper discusses the possibility of integrating and complement these technologies to maximize renewable energy production and circularity. The review was performed with a funnel approach aiming to analyze broad to specific subjects. Beginning with a literature review on the various definitions of circular economy, bioeconomy, and circular bioeconomy, ultimately proposing a single definition according to an industrial and academic scope combination, followed by a systematization and assessment of data and literature regarding energy systems present state and projections. The next phase was to assess data and literature of the fruit and vegetable processing industry from an energy consumption and biowaste production perspective to consequently discussing technologies that could help manage problems identified throughout this review. This paper culminates in propounding an Integrated Renewable Energy System conceptual model that promotes energy and waste circularity, envisioning how industries could be designed or redesigned in the future, coupled with a circular bioeconomy business model.

Micro-district heating networks based on cogeneration plants and renewable energy technologies are considered efficient, viable and environmentally-friendly solutions to realizing smart multi-energy microgrids. Nonetheless, the energy production from renewable sources is intermittent and stochastic, and cogeneration units are characterized by fixed power-to-heat ratios, which are incompatible with fluctuating thermal and electric demands. These drawbacks can be partially overcome by smart operational controls that are capable of maximizing the energy system performance. Moreover, electrically driven heat pumps may add flexibility to the system, by shifting thermal loads into electric loads. In this paper, a novel configuration for smart multi-energy microgrids, which combines centralized and distributed energy units is proposed. A centralized cogeneration system, consisting of an internal combustion engine is connected to a micro-district heating network. Distributed electric heat pumps assist the thermal production at the building level, giving operational flexibility to the system and supporting the integration of renewable energy technologies, i.e., wind turbines, photovoltaic panels, and solar thermal collectors. The proposed configuration was tested in a hypothetical case study, namely, a University Campus located in Trieste, Italy. The system operation is based on a cost-optimal control strategy and the effect of the size of the cogeneration unit and heat pumps was investigated. A comparison with a conventional configuration, without distributed heat pumps, was also performed. The results show that the proposed configuration outperformed the conventional one, leading to a total-cost saving of around 8%, a carbon emission reduction of 11%, and a primary energy saving of 8%.

Optimally selection of an appropriate mix of renewable sources for supplying electricity of remote areas has been always an important challenge for policy makers. Also, in recent years, the great advantages of Demand Side Management (DSM) programs such as postponing investments in construction of new plants and/or desirably modification of electricity consumption pattern has turned great attention of energy planners to these programs. Moreover, the issue of global warming has caused the need for reduction of human use of fossil fuels and switching to employing green energy sources. To address the mentioned concerns, in this paper, an integrated mathematical formulation for selecting the best mix of renewable energy technologies is proposed. In this study, DSM considered as a competitive option against supply-side alternatives for making energy planning decisions. Additionally, by considering real data from a case in Iran, the effects of considering energy import and export has been taken into account. To validate the model, for smaller-scaled test problems the model has been solved by Lingo 8.0 software while for solving larger instances of problems (real scale of case study) a novel genetic algorithm (GA) is devised. The numerical results indicate that DSM policies have made use of their maximum capacity and resulted in significant improvements, especially in terms of reducing consumption and suitably changing the load shape.

Decentralized Energy

Until recently, the prevailing idea was that for the functioning of the energy system it is necessary to be composed of large plants and for energy to move from the centre of production to cities and places of consumption. With the advent of decentralized energy production systems and new technologies for their use, the original model is changing more and more. EU Directive 2018/2001 on the promotion of the use of renewable energy sources (RES) designates “prosumers”, i.e. at the same time both producers and consumers of renewable energy, as well as RES communities, while EU Directive 2019/944 introduced the term “citizen energy communities”, i.e. civil energy communities, provided that this Directive, in addition to the distributive production of electricity from RES, also includes electricity from other sources. EU member states are obliged to adopt their own regulations regarding the implementation of the directives, and after that the appropriate incentive measures. The Energy Communities initiative offers citizens new opportunities in terms of active involvement in energy issues. As they are decentralized RES-based projects, they promote the practice of sustainable energy production and consumption, as well as energy storage and exchange within the community. Traditionally passive consumer becomes an energy “prosumer”, a co-owner of a RES plant and a member of the energy community. There are thousands of so-called RES cooperatives in Europe, which are the most common organizational form of energy communities and can play an important role in the process of decentralization of the energy system. The transition to decentralized energy production has many advantages, namely: the use of local energy sources, increased security of local energy supply, shorter transport distances and reduced losses in energy transmission, encouraging community development and creating local jobs. The purpose of this paper is to bring closer to the general public in Serbia the concept of energy communities, what they are and what their role is, with most of the work dealing with energy communities in the EU.
