Energy transition in islands constitutes a major challenge. Apart from a necessity, it can also be a great opportunity for sustainable social and economic development. Toward this direction, a new, promising movement has emerged recently in Greek islands. Straight from the roots of the insular population, development of energy communities comes as the result of increased awareness of local people, raised also by the legacy of lighthouse projects and initiatives. Kythnos, Ikaria, Sifnos, Tilos, Agios Efstratios, Crete, and Chalki, are all islands that have embraced the implementation of successful, local-scale innovation projects and/or initiatives, generating meaningful results across different energy aspects and contributing to positive social change. Our study provides an overview of the broader energy transition aspects in Greek islands, discusses the impact of the aforementioned exemplary cases, and further elaborates on the model of energy communities. According to our analysis, leveraging on the experience of lighthouse projects and initiatives, and on the dynamics of the emerging energy community movement, could lead to increased social and economic benefits for the insular populations, to broad public acceptance, and to minimum environmental impacts for the islands’ natural ecosystems.

In the context of the slowly progressing energy transition, a number of renewable energy initiatives have been emerging in the Netherlands. These initiatives represent alternatives to the dominant functioning of the energy system, and as such, may come into conflict with it. Transitions involve system destabilisation and conflict between the incumbent regime and the initiatives originating in niches. In order to assess the transformative potential of such initiatives, this paper addresses the question: what kind of conflicts and tensions arise from renewable energy initiatives, and what strategies do they develop to overcome or avoid them? Combined with a business model perspective, transition thinking enabled a better understanding of how the initiatives organise themselves, and where the points of friction with their institutional context emerge. We suggest that the instances of conflict may function as an indication for the state of the energy transition and the transformative potential impact of such initiatives. The instances discussed in this contribution relate to existing support schemes, technology choices, and the overall organisational networks of the emerging sector.

Renewable energy cooperatives envision and manifest an alternative way of organising within the energy system (and beyond). Yet, despite their growth, it is uncertain whether such initiatives are able to increase and deepen their impact, leading the transition to an environmentally sustainable and socially just energy system. This paper presents insights from a strategic dialogue co-organised with the Dutch national interest group of renewable energy cooperatives “ODE Decentraal”. We used transition management as action research methodology to organise the dialogue to understand and support the transformative potential of the cooperative energy movement. The dialogue helped to clarify the challenges and possibilities for scaling energy cooperatives beyond the niche, supporting at the same time the participants to reflect, strategize and develop a shared transition agenda. This contribution presents and analyses our intervention and its impact, also specifically evaluating the potential of transition management to facilitate social learning processes, reflexivity and the development of strategic actions. Our intervention confirmed the hypothesis that actors in the niche often focus too much on the competition with the regime for individual goals, thereby failing to collectively strategize and engage with incumbent regimes in a systematic way.

Combined heat and power (CHP) plants using biomass are considered important to substantially increase the share of renewables in the total energy supply and meet ambitious climate targets. The analysis focuses on the links between the size of bio-fuelled CHP plants and their techno-economic and environmental performance, as well as social acceptance. In an exploratory way, this paper compares the performance of six bioenergy plants in the Netherlands in these three key areas, thereby focusing on the link between the size of biomass plants and overall performance in an integrated multi-dimensional manner. The findings show that economic and environmental performance does not necessarily improve with scale and, in effect, several large-scale biomass plants score low in several environmental indicators. In addition, we find that there is often limited data availability on economic, environmental and social characteristics of biomass plants in the Netherlands, despite the fact that their operations are largely supported by public funds.
