AN AHP-GIS BASED APPROACH FOR SITE SUITABILITY ANALYSIS OF SOLAR-WIND PROJECTS IN SANTA MARTA, COLOMBIA

This paper presents an analysis to determine the suitable areas for the implementation of solar-wind projects in Santa Marta, Colombia. For this, an approach that integrates the decision-making tool of the Analytical Hierarchical Process (AHP) with Geographic Information Systems (GIS) was used. To identify the selection criteria, the existing literature and the renewable resources available in the study area were considered. Seven sub-criteria were identified (solar irradiation, wind speed, protected areas, armed conflict, indigenous reservations, populated zones and roads), which were weighted with the AHP by 15 experts with experience in projects with renewable energies. After performing a consistency analysis, it was found that 5 experts were consistent, while another 5 were discarded for being highly inconsistent. A consistency correction method was implemented for the remaining 5 experts, in order to have 10 experts for the weighting process. Each sub-criterion represents a map of the study area, which were superimposed in a GIS environment to implement the weighting obtained with the experts. A global map for the implementation of renewable energy projects, considering environmental, social and local infrastructure criteria was obtained. The map was classified into five categories: not suitable, marginally suitable, moderately suitable, highly suitable and optimally areas.Keywords: Renewable Energy, Analytical Hierarchical Process, Energy Planning, Geographic Information SystemsJEL Classifications: Q20, D70, Q42, D81DOI: https://doi.org/10.32479/ijeep.11266

Višekriterijumska ocena obnovljivih izvora energije u Srbiji

The development of today's economies is inconceivable without energy. However, fossil fuel reserves are declining, climate change is accelerating and some changes in the energy sector are needed. Renewable energy sources are a potential solution for many scientists and practitioners. However, the planning and implementation of renewable energy projects requires consideration of a number of criteria, which is why multicriteria decision-making methods are often used to evaluate renewable energy sources/technologies. Goal of this paper is to evaluate four types of renewable energy sources (photovoltaic, hydro, biomass and wind energy) in Serbia. Analytical hierarchical process and seven criteria were applied. Based on the obtained results, hydro sources are ranked the best. Also, a sensitivity analysis was conducted to determine whether changes in the priority of criteria would cause changes in the range of alternatives. It was found that major changes in priorities are needed for changes to occur, so it can be concluded that the results obtained are relevant.

The empirical failures of attaining the societal benefits of renewable energy development projects in Sub-Saharan Africa

Abstract The number of renewable energy (RE) projects that have been implemented in Sub-Saharan Africa (SSA) has soared over the past couple of years. The number of projects to be implemented within the coming years is expected to rise considerably. However, the societal benefits of RE projects implemented in SSA have not been studied thoroughly. This study attempts to: (i) uncover the differences between the expected and the realized societal benefits of utilizing renewable energy technologies (RETs) in SSA, (ii) reveal any empirical failures in realizing those benefits and (iii) create awareness towards the sustainable implementation of RE projects. Within the realm of publicly-funded projects, we aim to provide solutions that assist these and future projects to meet their societal benefits. We investigate 29 projects that have been implemented in ten SSA countries taking into account direct experiences of the local users and project developers. We find that most of the projects investigated in this study have few to no societal benefits within a short period of time after the “cutting the ribbon” event. To counteract this, we present corresponding recommendations.

Effect of Taiwan's energy policy on unit commitment in 2025

This study presents the effect of Taiwan's energy policy on its unit commitment in the year 2025. Taiwan's energy policy has been changing since 2005, since when it has required the decommissioning of nuclear power plants in response to the crisis in Fukushima, the adoption of the Kyoto Protocol, and the increase of renewable sources of power generation to 20% of its energy mix. The paper models the unit commitment for the Taiwan power system under Taiwan's energy policy. The study compares unit commitments in 2018, summer 2025, and winter 2025 using AMPL Software with the CPLEX 12.9.0 Solver. The results show that the net demand curve will change by 2025, forming a “duck – curve” model due to the high penetration of renewable energy. The daily carbon dioxide emission in 2018 for five percent (5%) spinning reserve is 392,151,000 kg. The said amount is larger than in winter 2025 when it will be 311,314,000 kg indicating the importance of the full implementation of renewable energy projects in helping to reach Taiwan's goal to limit carbon dioxide emission by 2025. Pumped storage scheduling changes from conventional pumping in the early morning to pumping from around noon to late afternoon due to the high penetration of renewable energy. The construction of combined-cycle units will have a critical role in the achieving of the spinning reserve capacity goal set by the Taiwan government, to avoid the importation of energy and to maintain the energy security of the country.

Choosing the lesser of two evils?

In the face of climate change, the transition to a low-carbon energy system has become increasingly urgent. However, the implementation of renewable energy projects is often contested. Now research shows that residents of wind energy communities prefer their local wind project over other means of electricity generation.

Spatial targeting, synergies and scale: Exploring the criteria of smart practices for siting renewable energy projects

Policies and strategies to develop renewable energy and the rates of successful deployment vary from country to country. Academic literature is rife with examples of recurring problems and malpractice in the implementation of renewable energy projects. We could see each national and sectoral effort as an ‘experiment’ in the early phase of our attempted transition to a low carbon energy system. What lessons can we learn from a comparative analysis of these experiments? This paper seeks to draw generic lessons not from what has gone wrong but from national case studies that stand out in a best way. Through a European academic network, we have selected and analysed 51 ‘smart practice’ case studies of renewable energy development from 20 countries. We present the outcomes of both qualitative and quantitative analysis of these case studies (smart practice criteria) and discuss a set of generic findings concerning specific types of smart practices and problems of potential transferability of projects to other regions. With regards to policy relevance, the findings can be used for evaluating portfolios of renewable energy projects developed to date and for setting guiding principles for project design, spatial planning and consent by means of cross-national learning and fertilization.

Business models and innovativeness of potential renewable energy projects in Africa

Abstract This study provides an overview of potential renewable energy (RE) projects for Africa. Pan African University master students were asked by their lecturer to characterize African projects they had in minds in uniform tables. Items of the project investment plan include project synopsis, the sponsors, market analysis and strategy, project scope, regulation and environmental information, project costs, financial projections, business model, and project innovativeness. Students' RE projects are assessed with emphasis put on employed business models and project innovativeness. Criticalities for the implementation of these projects are discussed in African contexts providing outlook for future investment opportunities in the African continent. The work provides insights from the local students' perspective for the various stakeholders interested in RE project investments in Africa. Useful suggestions formulated directly by young Africans are presented which may contribute to improved risks management when these or other potential RE projects will be deployed. Inputs from local people on how they understand the process of implementing RE projects in Africa might be interesting for investors seeking information about suitable ways for RE project deployment. Students characterize local contexts and identify numerous barriers for deployment of RE systems in Africa. Overall, this study explains the potential lying in renewable energy harvesting in Africa, seeks to emphasize major barriers for implementation of RE projects as well as investigates investment opportunities to implement economically feasible RE projects for cleaner and climate friendly energy future of this continent.

Entrepreneurship based on Intermodal Transport for the Installation of a Wind Turbine in Isolated Regime

Abstract The complex activities for the implementation of renewable energy projects (RES) need a well-documented entrepreneurial plan to find qualified suppliers for the development of RES projects. The activities of the chain links in RES projects, respectively, the transport of heavy components, require a collaborative logistics system to be continually monitored. The requirements stringency imposed for the implementation of wind energy projects inevitably implies infrastructure, implementation and logistical constraints. Special parts of the wind turbine can be difficult to handle due to their fragility, weight or size and therefore it requires special treatment when transported. This work, based on the Analytic Hierarchy Process (AHP) method, respectively through a decision model provides an entrepreneurial plan for the intermodal transport needed to assembly a wind turbine in isolated regime, where there are challenges related to the high transport distance, low road standard and rough climate.

An Interactive Planning Support Tool for Addressing Social Acceptance of Renewable Energy Projects in The Netherlands

The implementation of renewable energy policies is lagging behind in The Netherlands. While several Dutch cities have ambitious goals for reducing greenhouse gas (GHG) emissions, the implementation of renewable energy projects has been rather slow. The main reasons for this are the limited institutional capacities of local decision-makers, low levels of social acceptance of renewable-energy technologies, and limited opportunities for engagement of communities in decision-making processes. In order to address these issues we have developed an interactive planning support tool named COLLAGE for stakeholder participation in local renewable-energy planning. The goal of this paper is to analyze whether the COLLAGE tool helps to increase community engagement in renewable-energy projects and planning by increasing awareness and addressing social learning issues related to renewable-energy options. We tested the tool in a series of workshops with stakeholders and citizens from the city of Enschede, The Netherlands. The workshop results show that the tool helped involve stakeholders and communities in deciding where to locate renewable-energy facilities. It increased community members’ awareness of the benefits of and requirements for renewable energy by disclosing the spatial consequences of overall municipal goals. We conclude that the COLLAGE tool can be an important building block towards new local energy governance.

Looking beyond incentives: the role of champions in the social acceptance of residential solar energy in regional Australian communities

ABSTRACTResearch into renewable energy adoption is increasingly identifying that the successful implementation of renewable energy projects is influenced by a combination of market, community and socio-political acceptance of renewable energy technology. This research uses case studies in two regional Australian communities to examine the social acceptance of residential solar energy, in particular under the influence of financial incentives and social interactions. Fifty-five semi-structured interviews with members of the local community, industry and government were undertaken between May and October 2015. Respondents were asked about their perceptions and knowledge of solar energy and incentives to support its adoption, and their interactions with actors important in the diffusion process. Responses indicated that financial incentives motivated solar adoption; however, social interactions in the communities also contributed to decision-making. In one case study, a local “solar champion” built a private solar farm to demonstrate the technical feasibility of solar, assisted community members with physically installing their own systems and helped community members to maximise the financial benefits of their solar installations. This solar champion contributed to this community having an earlier and more rapid rate of small-scale solar adoption compared with the second case study community. The second case study community included two individuals interested in promoting solar energy; however, they were less integrated with the community’s process of adopting solar, resulting in community members experiencing substandard installations and consequent distrust of the solar industry. This research concludes that local context influences solar adoption through complex interactions among market, community and socio-political acceptance.

Public estimates of support for offshore wind energy: False consensus, pluralistic ignorance, and partisan effects

Meeting future energy demands will require large-scale implementation of renewable energy projects. If one of these energy sources—offshore wind—becomes a common sight off coastlines, consideration of local public opinion and action will be critical. Previous research from the social sciences has lacked depth in examining the underlying factors that shape public opinion towards offshore wind development. The current research brings a new perspective to the literature by showing that how members of the public perceive support among others relates to their own opinions of offshore wind energy. We report results from two surveys. The first focused on opinion formation relating to offshore wind in general among New England residents, while the second focused on a specific offshore wind project in Rhode Island. We find evidence that both supporters and opponents of offshore wind underestimate levels of support among others, indicating a pluralistic ignorance effect and false consensus effect, respectively. We also find distinct patterns of perceived support among self-identified Republicans and Democrats. The findings hold important implications for policymakers and developers in understanding the nature of public support and opposition for offshore wind energy, particularly with respect to individuals’ willingness to publicly engage with offshore wind projects.

Failures & generic recommendations towards the sustainable management of renewable energy projects in Sub-Saharan Africa (Part 2 of 2)

Renewable energy (RE) generation is expected to become the main source of energy in Sub-Saharan Africa (SSA) over the next century. However, more often than not, the sustainability aspect of these projects is a characteristic that is not clearly defined in terms of projects implemented in SSA. The rate at which projects fail is creating a negative impact towards the full acceptance of renewable energy technologies (RETs).The aim of this paper is to comprehensively explore the reasons of failures and provide recommendations towards the sustainable management of RE projects in SSA. We accomplish this by combining findings from past literature on the failures of RE projects in SSA with an ethnographic approach and practical experience in the implementation of RE projects in Sub-Saharan Africa. We propose the following solutions: (i) transparency, (ii) ownership, (iii) shared responsibility and (iv) community involvement. We further present hermeneutic recommendations that should be taken into account by stakeholders towards implementation of any sustainable renewable energy project.

Analysis of renewable energy projects’ implementation in Russia

With the enactment in 2013 of a renewable energy scheme by contracting qualified power generation facilities working on renewable energy sources (RES), the process of construction and connection of such facilities to the Federal Grid Company has intensified in Russia. In 2013–2015, 93 projects of solar, wind, and small hydropower energy were selected on the basis of competitive bidding in the country with the purpose of subsequent support. Despite some technical and organizational problems and a time delay of some RES projects, in 2014–2015 five solar generating facilities with total capacity of 50 MW were commissioned, including 30 MW in Orenburg oblast. However, the proportion of successful projects is low and amounts to approximately 30% of the total number of announced projects. The purpose of this paper is to analyze the experience of implementation of renewable energy projects that passed through a competitive selection and gained the right to get a partial compensation for the construction and commissioning costs of RES generating facilities in the electric power wholesale market zone. The informational background for the study is corporate reports of project promoters, analytical and information materials of the Association NP Market Council, and legal documents for the development of renewable energy. The methodological base of the study is a theory of learning curves that assumes that cost savings in the production of high-tech products depends on the production growth rate (economy of scale) and gaining manufacturing experience (learning by doing). The study has identified factors that have a positive and a negative impact on the implementation of RES projects. Improvement of promotion measures in the renewable energy development in Russia corresponding to the current socio-economic situation is proposed.

Creative Educational Methods in Implementation of Investment Projects in Renewable Energy

Implementation of renewable energy projects (RES) involves very complex processes which are based on the latest creative techniques to give adequate solutions teaching practitioners of this multidisciplinary field. The need for a complex transfer of knowledge at the administrative level, technical level and technological level of RES projects, constitute prerequisites for success in projects implementation of this type. The present paper proposes using creative educational methods for implementing investment projects in renewable energy using a combination of methods of Goldratt. To exemplify bottleneck situations in the management of certain flows within the supply chain of the RES implementation projects, the paper proposes Drum-Buffer-Rope philosophy. In order to underline the effectiveness in fast obtaining and implementing the right solutions along the lifecycle of RES projects, the paper illustrates the steps of Theory of Constraints Thinking Process (TOCTP) integration by problem diagnosing, designing the solutions plan and integrating the solutions plan through the conceptualization of adequate diagrams communication within these types of projects.

The Application of Clean Development Mechanism as a Driver for Renewable Energy Projects in Malaysia

The issue of climate change has long been attributed to the extensive amount of carbon emission through the utilization of fossil fuel as our primary energy source. As this source reaches depletion, the search for alternative and renewable energy options has received much attention on a global scale. The two-pronged approach of renewable energy projects reducing global greenhouse gas emissions through substitution of fossil fuels and prolonging the lifespan of non-renewable energyis deemed as the key to our endeavour for sustainable development. The Clean Development Mechanism under the Kyoto Protocol can act as a tool to provide the financial and technological thrust necessary for effective implementation of renewable energy projects in developing nations. Malaysia, in all its potential, currently utilizes less than 1% of its potential renewable energy capacity despite its recent political and economical advancements in this respect. This paper will assess the untapped potential of renewable energy and status of the CDM in Malaysia, and discuss how the CDM can act as a driver for renewable energy projects in developing nations including Malaysia.

Renewable Energy Technology and Path Creation: A Multi-scalar Approach to Energy Transition in the UK

This paper examines the potential contribution of UK regions for developing and deploying renewable energy technologies to achieve the government target of obtaining 20% of its energy from renewable sources by 2020. The paper argues for a multi-scalar approach to energy transition theory and policy. National-scale processes and policies need to be complemented by regional and local policies in order to discover and incorporate meso-level sources of renewable energy, recognize that niche or path creation is a geographically localized process and mobilize heterogeneous, local actors around common “regional energy visions” to improve implementation of renewable energy projects. After critically reviewing the main theoretical approach to energy transitions, the multi-level perspective, the paper employs patent data to describe the comparative position of UK regions in the renewable energy sector and examines the success of Danish, German and Spanish regions resulting from strong government intervention at the national level supplemented by region-specific strategies. A number of policy strengths and shortcomings are identified in the evolutionary trajectory of the UK energy system including weak technology push and policy pull factors. Finally, the paper reviews existing regional renewable energy policy and speculates on the potential impact of recent changes in spatial and energy policies on the ability to deploy and develop renewable energy sources in the UK.

Social enterprise and renewable energy: emerging initiatives and communities of practice

PurposeAfter years of attempting to develop renewable energy (RE) mainly through large private sector initiatives, the UK government has broadened its approach to provide more support for other actors in this sector. The purpose of this paper is to assess what role social enterprise (SE) activities can play in the development of the RE sector in the UK.Design/methodology/approachThe approach consists of an initial effort to map the sector in terms of project types; and to assess the benefit of supporting SE activities in RE through an empirical case study. Two types of SE‐RE initiatives are examined here, namely a Scottish SE‐RE consultancy (the Highlands and Islands Renewable Energy Company – HICEC) and the various SEs it supports in developing RE projects through grants like the Scottish Community and Household Renewables Initiative (SCHRI).FindingsA typology of enterprise activities in RE is developed, based on activities along the RE supply chain. The case study demonstrates the value of partnership working between HICEC staff and the staff of local SEs, and suggests that the emergence of a community of practice is a key benefit of the SCHRI and the collaborative way in which it was implemented by HICEC. The success of this approach does throw up questions about replicability in different geographical settings.Originality/valueThis is the first paper to explore SE activities in RE. It illustrates that collaborative learning‐by‐doing by individuals across organisational boundaries is key for the successful implementation of RE projects that are new to the UK.

Governmental policy and prospect in electricity production from renewables in Lithuania

In Lithuania, the generation of electricity is based on the nuclear energy and on the fossil fuels. After the decommissioning of Ignalina nuclear power plant in 2009, the Lithuanian Power Plant and other thermal plants will become the major sources of electricity. Consequently, the Lithuanian power sector must focus on the implementation of renewable energy projects, penetration of new technologies and on consideration of the future opportunities for renewables, and Government policy for promoting this kind of energy. Production of electricity from renewable energy is based on hydro, biomass and wind energy resources in Lithuania. Due to the typical climatic condition in Lithuania the solar photovoltaics and geothermal energy are not used for power sector. Moreover, the further development of hydropower plants is limited by environmental restrictions, therefore priority is given to wind energy development and installation of new biomass power plants. According to the requirements set out in the Directive 2001/77/EC of the European Parliament and of the Council of 27 September 2001 on the promotion of electricity produced from renewable energy sources in the internal electricity market [Official Journal L283, 33–40, 27 October 2001], 7% of gross consumption of electricity will be generated from renewable energy by 2010 in Lithuania. The aim of this paper is to show the estimation of the maximum renewable power penetration in the Lithuanian electricity sector and possible environmental impact.

Promotional policy and perspectives of usage renewable energy in Lithuania

The article outlines renewable energy (RE) sources according to the energy efficiency policy in Lithuania as well as practical experience of implementation of RE projects within the framework of the government policy to promote RES use due to the requirement of the European Union. The main goal of the country is to reduce the import of fossil fuel, to improve environment conditions and to reduce the climate change impact. Analysis of implemented RE projects and forecasts for the future projects are also presented. Most of the efforts in Lithuania were aimed at drafting the biomass (wood chips, wood waste, straw, biogas) and small hydro projects and their subsequent implementation. At present the total capacity of wood-chip-fuelled boilers reached above 251 MW. No serious obstacles can be seen for the extension of wood fuel use. At present, new demonstrational projects have been started covering geothermal energy, solar energy, biogas, biofuels for transport and other. In this time, the RE sources comprise 7.69% of national energy balance. Taking into account feasible resources of RE (it is more than 19.85 TWh/year) and the ongoing implementation of projects it is clear that the share of RE sources will constitute 12–13% of national energy balance in 2010 year. The main factor limiting further growth is high investment costs. The electricity production from local and RE sources in Lithuania is mainly based on hydro energy. At this time the wind energy is not used for this purpose. The electricity production from local and renewable energy sources is about 3.22% of the total consumption.

Renewable energy policy in Lithuania

The article outlines renewable energy (RE) resources according to the energy efficiency policy in Lithuania as well as practical experience of implementation of RE projects within the framework of the National Energy Efficiency Programme. The main goals of the programme are to reduce the import of energy resources, to improve environment conditions and to reduce the climate change impact. Analysis of implemented RE projects and forecasts for the future projects are also presented. The use of biomass (wood chips, processing wastes, sawdust, straw, etc.), biogas, as well as small-scale hydro energy sources is increasing in Lithuania. Quite a few plants utilising renewable energy resources were constructed within the framework of co-operation with European Union countries (Sweden, Denmark, German, etc.) along with the establishment of joint companies for production of equipment, facilities, etc. Recently a few pilot projects utilising geothermal, wind, solar and landfill gas energy have been started. Lithuania expected to make an important contribution to reach the goals set by the European Commission's White Paper on RES (increasing the share of renewables in the overall energy balance up to 12% by 2010).
