This presentation focusses on how societies can design and implement renewable energy and decarbonization strategies. The presentation presents and discuss a set of methods and criteria to design Smart Energy Systems, while considering the context of 100% renewable energy on a national level. Countries should handle locally what concerns local demands, and at the same time acknowledge the international context when discussing resources and industrial and transport demands. To illustrate the method, it is applied to the cases of Denmark and European within the context of a global fully decarbonized energy system.
Recently, the Danish Government supported by the Danish Parliament decided for the target of a 70% decrease in Greenhouse gasses by 2030. This presentation includes a list of theoretical and methodological considerations as well as a concrete proposal on how such targets can be implemented. It is highlighted that already now one must think beyond 2030 to prepare for the next step to achieve a full decarbonization by 2040 or 2050. It is also highlighted that a country such as Denmark must consider how to include its share of international shipping and aviation as well as how to design a solution with Denmark’s share of sustainable biomass resources.
Moreover, the presentation includes the results of detailed hourly modelling of the EU “A Clean Planet” scenarios for a fully decarbonized Europe in 2050 and compare it to a “smart energy systems” alternative. The case illustrates how the focus on a fully sector-coupling as expressed in a smart energy systems approach will lead to higher energy efficiency and the identification of a more affordable green transition in Europe.
