Candelise C, Saccone D, Vallino E, 2021, An empirical assessment of the effects of electricity access on food security, World Development, Vol: 141, Pages: 1-14, ISSN: 0305-750X
Energy access, as defined in SDG 7, is a consistent component of decent livelihood and is therefore strictly connected to the fulfillment of the broad goal of sustainable development. While it may have significant impacts on various dimensions of development and sustainability, this study focuses on its effect on the level of food security of the overall population (SDG 2). Although there are many reasons to suppose that electricity access is positively related to food security, such impacts are expected to accrue through both immediate and income-mediated routes whose size and prevalence are unknown. The immediate impacts of electricity access on food security refer to the effects on food production (availability) and on food conservation and preparation (utilization). Income-mediated impacts include cross-sectoral productivity increases and the creation of new economic activities, generating new income that, in turn, would improve the economic access to food.
Wierling A, Zeiss JP, Lupi V, et al., 2021, The contribution of energy communities to the upscaling of photovoltaics in Germany and Italy, Energies, Vol: 14, Pages: 1-16, ISSN: 1996-1073
<jats:p>Energy communities (EC) are among the new actors in the energy market, playing an important role in the uptake of photovoltaics (PV) in European markets. This paper estimates their aggregate contribution to the low-carbon energy transition in terms of installed capacities for PV and evaluates their economic performance comparing with market prices. We compiled a database of PV facilities with 3672 entries for Germany and 64 entries for Italy. Our statistical analysis does not support an economic under-performance of EC. The aggregate contribution of EC currently amounts to 600–838 MWp installed capacity in Germany and 10.6 MWp installed capacity in Italy, which makes 1.2–1.7% and 0.07% of all PV installations in Germany and Italy, respectively.</jats:p>
Few S, Djapic P, Strbac G, et al., 2020, Assessing local costs and impacts of distributed solar PV using high resolution data from across Great Britain, Renewable Energy, Vol: 162, Pages: 1140-1150, ISSN: 0960-1481
Highly spatially resolved data from across Great Britain (GB) are combined with a distribution network modelling tool to assess impacts of distributed photovoltaic (PV) deployment up to 2050 on local networks, the costs of avoiding these impacts, and how these depend upon context. Present-day deployment of distributed PV, meter density, and network infrastructure across GB are found to be highly dependent on rurality, and data on these are used to build up three representative contexts: cities, towns, and villages. For each context, distribution networks are simulated, and impacts on these networks associated with PV deployment and growth in peak load up to 2050 calculated. Present-day higher levels of PV deployment in rural areas are maintained in future scenarios, necessitating upgrades in ambitious PV scenarios in towns and villages from around 2040, but not before 2050 in cities. Impacts of load growth are more severe than those of PV deployment, potentially necessitating upgrades in cities, towns, and villages from 2030. These are most extensive in cities and towns, where long feeders connect more customers, making networks particularly susceptible to impacts. Storage and demand side response are effective in reducing upgrade costs, particularly in cities and towns.

Candelise C, Ruggieri G, 2020, Status and evolution of the community energy sector in Italy, Energies, Vol: 13, Pages: 1-22, ISSN: 1996-1073
Community energy (CE) initiatives have been progressively spreading across Europe and are increasingly proposed as innovative and alternative approaches to guarantee higher citizen participation in the transition toward cleaner energy systems. This paper focuses the attention on Italy, a Southern European country characterized by relatively low CE sector development. It fills a gap in the literature by eliciting and presenting novel and comprehensive evidence on recent Italian CE sector developments. Through a stepwise approach it systematically maps and reviews Italian CE initiatives, to then focus the attention on three specific case studies to further explore conditions for development as well as of success within the Italian energy system. The analysis presents an Italian CE sector still at its niche level, characterized by small initiatives largely dependent on national photovoltaics (PV) policy support. It also points out how only larger initiatives, able to operate at national scale, developing multiple projects and differentiating their activities have managed to continue growing at the time of discontinuity of policy support and contraction of the national renewable energy market. Recent EU and national legislative development might support revived development of CE initiatives in Italy.
Gregg JS, Nyborg S, Hansen M, et al., 2020, Collective action and social innovation in the energy sector: a mobilization model perspective, Energies, Vol: 13, Pages: 1-24, ISSN: 1996-1073
This conceptual paper applies a mobilization model to Collective Action Initiatives (CAIs) in the energy sector. The goal is to synthesize aspects of sustainable transition theories with social movement theory to gain insights into how CAIs mobilize to bring about niche-regime change in the context of the sustainable energy transition. First, we demonstrate how energy communities, as a representation of CAIs, relate to social innovation. We then discuss how CAIs in the energy sector are understood within both sustainability transition theory and institutional dynamics theory. While these theories are adept at describing the role energy CAIs have in the energy transition, they do not yet offer much insight concerning the underlying social dimensions for the formation and upscaling of energy CAIs. Therefore, we adapt and apply a mobilization model to gain insight into the dimensions of mobilization and upscaling of CAIs in the energy sector. By doing so we show that the expanding role of CAIs in the energy sector is a function of their power acquisition through mobilization processes. We conclude with a look at future opportunities and challenges of CAIs in the energy transition.

Candelise C, 2016, The application of crowdfunding to the energy sector, Crowdfunding for Sustainable Entrepreneurship and Innovation, Publisher: Business Science Reference, Pages: 266-287, ISBN: 9781522505686
Crowdfunding in energy begins as a response to reduced investments (both governmental and private) into the transition to decarbonized energy systems and to the spread of innovative business models and approaches conductive of greater participation of citizens and communities in distributed renewable energy projects. This chapter presents results of a worldwide overview of the use of crowdfunding in the energy industry. Evidence gathered from available energy crowdfunding platforms highlight a very new, but quite dynamic sector. The crowdfunding tool has been applied in most of its forms, ranging from peer-to-business lending to pure donation, with strong environmental and social mission and the explicit aim of increasing participation of citizens in sustainable energy investment. Evidence also shows that, despite maintaining their environmental and clean energy focus, some energy platforms have begun to move from niche, grass root initiatives into larger projects and collaboration with energy private sector and institutional finance.
Westacott P, Candelise C, 2016, Assessing the impacts of photovoltaic penetration across an entire low-voltage distribution network containing 1.5 million customers, IET Renewable Power Generation, Vol: 10, Pages: 460-466, ISSN: 1752-1416
Deployment of grid-connected photovoltaics (PV) in the UK has increased rapidly. By 2014 there were over 650,000 installations (over 5 GWp), spread over different market segments (on site of existing domestic and non-domestic electricity demand customers, or connected directly to the network, e.g. solar farms). This rapid deployment and diverse market segmentation raises questions about impacts upon the electricity network. Here the authors present a novel geographical information system framework which maps current PV deployment and electricity demand to sensitive spatial resolution and by market segment. This is used to understand how current PV deployment affects power flows between the high-voltage (HV) and low-voltage (LV) network. The analysis reveals that overall, current LV PV generation is significantly below summer daytime LV demand – with over half of the areas investigated showing electricity demand five times greater than peak PV generation. Interestingly a small number of areas exhibit peak PV generation greater than demand, where reverse power flow from LV to HV may occur. The framework is hence capable of identifying the areas where network impacts are likely to occur and will also be useful to consider how integration strategies, such as energy storage and demand response could facilitate further PV deployment.

Westacott P, Candelise C, 2016, A Novel Geographical Information Systems Framework to Characterize Photovoltaic Deployment in the UK: Initial Evidence, Energies, Vol: 9, ISSN: 1996-1073
Globally, deployment of grid-connected photovoltaics (PV) has increased dramatically inrecent years. The UK has seen rapid uptake reaching over 500,000 installations totalling 2.8 GWpby 2013. PV can be installed in different market segments (domestic rooftop, non-domestic rooftopand ground-mounted “solar-farms”) covering a broad range of system sizes in a high number oflocations. It is important to gain detailed understanding of what grid-connected PV deploymentlooks like (e.g., how it deployed across different geographic areas and market segments), and identifythe major drivers behind it. This paper answers these questions by developing a novel geographicalinformation systems (GIS)-framework—the United Kingdom Photovoltaics Database (UKPVD)—toanalyze temporal and spatial PV deployment trends at high resolution across all market segments.Results show how PV deployment changed over time with the evolution of governmental PVpolicy support. Then spatial trends as function of local irradiation, rurality (as a proxy of buildingand population density) and building footprint (as a proxy for roof-area) are analyzed. We findin all market segments, PV deployment is strongly correlated with the level of policy support.Furthermore, all markets show a preference to deploy in rural areas and those with higher irradiation.Finally, local clustering of PV in all market segments was observed, revealing that PV is not spreadevenly across areas. This work reveals the complex nature of PV deployment, both spatially and bymarket segment, reinforcing the need capture this through mapping.

Houari Y, Speirs J, Candelise C, et al., 2013, A system dynamics model of tellurium availability for CdTe PV, Progress in Photovoltaics: Research and Applications, Pages: n/a-n/a, ISSN: 1099-159X
The routine availability of key component materials has been highlighted as a potential constraint to both extensive deployment and reduction in production costs of thin-film photovoltaic (PV) technologies. This paper examines the effect of material availability on the maximum potential growth of thin-film PV by 2050 using the case of tellurium (Te) in cadmium telluride (CdTe) PV, currently the dominating thin-film technology with the lowest manufacturing cost. The use of system dynamics (SD) modelling allows for a dynamic treatment of key Te supply features and prospects for reductions in PV demand via material efficiency improvements, as well as greater transparency and a better understanding of future recycling potential. The model's projections for maximum Te-constrained CdTe PV growth by 2050 are shown to be higher than a number of previous studies using static assumptions—suggesting that a dynamic treatment of the resource constraints for CdTe inherently improves the outlook for future deployment of this technology. In addition, the sensitivity analysis highlights certain complex correlations between the maximum potential CdTe growth by 2050 and the rated lifetime of PV modules as well as the reported size of global Te resources. The highest observed sensitivities are to the recovery rate of Te from copper anode slimes, the active layer thickness, the module efficiency and the utilisation rate of Te during manufacturing, all of which are highlighted as topics for further research.

Gazis E, Candelise C, Winskel M, 2013, Cost Leadership or Diversification? Assessing the Business Strategies of PV Manufacturers Using Case Studies from the USA and the UK, 28th European Photovoltaic Solar Energy Conference and Exhibition
The recent explosive growth of the PV sector combined with the multiple technological advancements have allowed for extensive experimentation in terms of applications and business models. This paper follows on a previous market assessment and offers a mapping of the various business strategies adopted by PV firms. It investigates real case-studies to analyse the benefits and dangers related to diversification through product and market differentiation. Finally it provides insights for the growth potential of such firms taking into consideration not only the techno-economic characteristics that are intrinsic to each one, but also the wider socioeconomic environment. The analysis combines literature research with original empirical evidence gathered using interviews with PV experts and comparative firm-level case studies. It then draws upon innovation studies, technological transitions and business literature to provide a novel analytical framework for the understanding of the factors facilitating or hindering the successful commercialisation of innovative PV applications. This work is part of the EPSRC’s Supergen PV21 Consortium (PV Materials for the 21st Century) and as such it draws upon leading expertise in TF PV technologies.
