Climate change is the defining issue of our time (United Nations, 2018). Renewable energy, combinedwith energy efficiency, can potentially be the most effective solution to address energy-relatedGreenhouse Gas (GHG) emissions. This work covers global, regional and national strategies to acceleratedeployment of renewable energy in power, transport and industry, using a variety of methodologies toaddress sectoral challenges and account for sectoral specificities. These sectors jointly represented 85%of energy-related emissions in 2016 (IRENA, 2019a).The thesis is structured around four focus areas. Foci 1-3 investigate the key components of an energytransformation jigsaw that looks at key sectors in which renewable energy can be integrated: i...
