Abstract: A critical review of the literature highlighted the need for a new taxonomy encompassing the most relevant barriers stemmed from previous studies, and accounting for interactions and independences of the barriers to avoid overlaps and implicit interactions. Based on an extensive literature review the paper provides a novel approach for barriers to the adoption of industrial energy-efficient technologies, coping with the issues risen by the review of the literature. We developed a taxonomy adaptable to empirical research, and able to evaluate the differences between perceived and real barriers, the effect of the barriers on decision-making processes, and the interactions among barriers. We modeled three types of interactions, i.e., causal relationship, composite effect and hidden effect, in order to start analyzing the dynamics among barriers, and tested the taxonomy in a preliminary investigation. The study proposes a useful instrument both to enterprises and policy-makers to identify critical factors to improve industrial energy efficiency and to open the research to further investigation in this topic.

The potential for optimizing, in both economic and energetic terms, the final waste treatment system in the Netherlands is evaluated in the light of the performance of new technologies. Projections of the final waste supply and waste treatment technologies are combined to construct several scenarios for waste treatment in the year 2010. Technologies include processes currently in the demonstration or pilot phase. It is concluded that final waste treatment could be performed at lower cost and with substantially greater energy recovery than at present. In a minimum cost scenario, the final waste treatment might cost 300/600 MECU/year, compared to 1000/1600 MECU/year in a reference scenario, on the assumption that conventional, but improved waste treatment technologies are used. A maximum energy recovery scenario mightsave 80/90 PJ primary energy per year compared to 39/47 PJ/year for the reference case. Two major competing technologies are gasification, both for biomass waste and integral waste, and fluidized bed incineration. Further development of these technologies integrated with electricity production is recommended. [ABSTRACT FROM AUTHOR]

Sustainable energy development is a complex multi-dimensional concept that can vary in meaning based on the context it is applied in and the perspective of the user. The role of energy in achieving sustainable development was recognized when the concept was first put forward in 1987. However, what that role consisted of was not made clear. Since then, the concept of sustainable energy development has developed to become a prominent policy objective on the international agenda, as evidenced by the introduction of the UN's Sustainable Development Goal 7 on energy. This paper presents an overview of the history of the concept as well as its emerging themes. Through a citation analysis, the most cited open-access publications relevant to the concept were identified. A thematic analysis of these most cited publications led to the identification of four interrelated themes of sustainable energy development; access to affordable modern energy services, sustainable energy supply, sustainable energy consumption, and energy security. The overarching goal of sustainable energy development was defined as furthering sustainability. Equitable access to affordable and reliable modern energy services is integral to sustainable development. A transformation of the current energy system is necessary to reduce its harmful impacts, both on the supply and demand side. This transformation is not possible unless it is economically viable through, for instance, cost-competitive technologies and changes in energy pricing to reflect the external costs of energy. • Sustainable energy development is a young multi-dimensional concept. • Common themes of sustainable energy development are identified. • Access to modern energy services for all is essential to further sustainable development.

Sustainable energy development has become an international policy objective and an integral part of sustainable development. It is necessary to develop a robust and comprehensive set of indicators to monitor progress towards sustainable energy development. This analysis aimed to assess established indicator sets for sustainable energy development. The characteristics of a comprehensive and robust indicator set were identified to enable such an assessment and used as a basis for six assessment criteria; transparency of indicator selection and indicator application, conceptual framework, representative, linkages, and stakeholder engagement. A total of 57 indicator sets were found that monitor progress towards sustainable energy development or some aspects of it. All but one of these indicator sets were found to be lacking in some aspect, especially regarding a lack of transparency and consideration of linkages between indicators, presentation of an imbalanced picture, and no involvement of stakeholders during indicator development. The only indicator set that met all criteria were Energy Indicators for Sustainable Development developed jointly by multiple international agencies. Nonetheless, several flaws in this set were identified. The Energy Indicators for Sustainable Development could be considered as an initial basket of indicators for further refinement in the context where they will be applied to ensure their policy relevance and usefulness. The refinement process would benefit from more stakeholder input to take into account the specific context and make sure that there is a balance in the representation of the three dimensions of sustainable development. • Sustainable energy development is a policy objective that needs robust indicators. • The characteristics of robust and comprehensive indicator sets were identified. • Most current indicators for sustainable energy development are found lacking. • Energy Indicators for Sustainable Development are a good first building block.

The industry sector is a major energy consumer and GHG emitter. Effective climate change mitigation strategies will require a significant reduction of industrial emissions. To better understand the variations in the projected industrial pathways for both baseline and mitigation scenarios, we compare key input and structure assumptions used in energy-models in relation to the modeled sectors' mitigation potential. It is shown that although all models show in the short term similar trends in a baseline scenario, where industrial energy demand increases steadily, after 2050 energy demand spans a wide range across the models (between 203 and 451 EJ/yr). In Non-OECD countries, the sectors energy intensity is projected to decline relatively rapidly but in the 2010–2050 period this is offset by economic growth. The ability to switch to alternative fuels to mitigate GHG emissions differs across models with technologically detailed models being less flexible in switching from fossil fuels to electricity. This highlights the importance of understanding economy-wide mitigation responses and costs and is therefore an area for improvements. By looking at the cement sector in more detail, we show that analyzing each industrial sub-sector separately can improve the interpretation and accuracy of outcomes, and provide insights in the feasibility of GHG abatement.
