Abstract:

This editorial introduces the main findings from the 29th Volume of the International Journal of Sustainable Energy Planning and Management. The issue includes both contributions to the 2019 Sustainable Development of Energy Water and Environmental Systems conference and ordinary journal submissions. In either case, the research is centred on sustainable development using renewable energy systems – with particular attention to technology assessment, pricing & regulation and systems analyses. Case studies and model development from Austria, Cape Verde, Columbia, and Iran are presented – with varying focal points. Different drive trains for the electrification of the transportation sector are assessed. Lastly, pricing regimes for evolving district heating systems as well as consumer involvement in 4th generation district heating and social factors for implementing building energy conservation policy are considered
