TL;DR: In this article, the concept of 4th Generation District Heating (4GDH) was defined, including the relations to district cooling and the concepts of smart energy and smart thermal grids.
1,654 citations
TL;DR: In this article, the authors present the development and design of coherent smart energy systems as an integrated part of achieving future 100% renewable energy and transport solutions, which can potentially pave the way to a bioenergy-free, renewable energy- and transport system.
882 citations
TL;DR: It is quantified how benefits exceed costs by a safe margin with the benefits of systems integration being the most important.
373 citations
TL;DR: In this paper, an integrated cross-sector approach is used to determine the most efficient and least-cost storage options for the entire renewable energy system concluding that the best storage solutions cannot be found through analyses focusing on the individual sub-sectors.
Abstract: It is often highlighted how the transition to renewable energy supply calls for significant electricity storage. However, one has to move beyond the electricity-only focus and take a holistic energy system view to identify optimal solutions for integrating renewable energy. In this paper, an integrated cross-sector approach is used to determine the most efficient and least-cost storage options for the entire renewable energy system concluding that the best storage solutions cannot be found through analyses focusing on the individual sub-sectors. Electricity storage is not the optimum solution to integrate large inflows of fluctuating renewable energy, since more efficient and cheaper options can be found by integrating the electricity sector with other parts of the energy system and by this creating a Smart Energy System. Nevertheless, this does not imply that electricity storage should be disregarded but that it will be needed for other purposes in the future.

TL;DR: Based on a review of 11 municipal energy plans, the authors examines to what extent municipal energy planning matches national 100% renewable energy strategies, and suggests that the role of municipalities as energy planning authorities needs to be outlined more clearly in, e.g., strategic energy planning which integrates savings, efficiency and renewable energy in all energy sectors.

TL;DR: The article as discussed by the authors proposes a variety of methodological and topical areas, along with 75 research questions, that could deepen and broaden energy research, connected in part to all of the articles in this special (inaugural) issue of Energy Research & Social Science.
Abstract: Social science related disciplines, methods, concepts, and topics remain underutilized, and perhaps underappreciated, in contemporary energy studies research. To make this case, the article offers both quantitative and qualitative data. It begins with the quantitative part, providing a content analysis of 4444 research articles involving 9549 authors and 90,079 references (from a smaller subsample) published in three leading energy journals from 1999 to 2013. Within this vast sample, only 19.6 percent of authors reported training in any social science discipline, and less than 0.3 percent of authors reported disciplinary affiliations in areas such as history, psychology, anthropology, and communication studies. Only 12.6 percent of articles utilized qualitative methods and less than 5 percent of citations were to social science and humanities journals. The article then shifts to the qualitative part, where it proposes a variety of methodological and topical areas, along with 75 research questions, that could deepen and broaden energy research, connected in part to all of the articles in this special (inaugural) issue of Energy Research & Social Science (ERSS). Readers from all disciplines are encouraged to read it—especially the parts dealing with areas and concepts outside of their own areas of expertise.
1,066 citations
TL;DR: In this paper, the authors present the methodology and results of the overall energy system analysis of a 100% renewable energy system, which includes hour by hour computer simulations leading to the design of flexible energy systems with the ability to balance the electricity supply and demand.
1,032 citations
TL;DR: In this paper, two national energy systems are modelled, one for Denmark, including combined heat and power (CHP) and the other a similarly sized country without CHP (the latter being more typical of other industrialized countries).
