... Other research aggregates the sub-regions, so that the world can be represented by 23 regions [37], or an integrated analysis for Europe-Eurasia-MENA [38] or the East Asian Super Grid [39], all in full hourly resolution and interconnected. The 9 major regions are: Europe [40], Eurasia [41], MENA [42], Sub-Saharan Africa [43], India/ SAARC [32], Northeast Asia [30], Southeast Asia and Pacific [44,45], North America [46] and South America [47,48]. Solar PV is represented in the model by ground-mounted optimally tilted and single-axis tracking PV power plants and prosumer rooftop systems, enhanced by batteries in the cases of financial attractiveness for the prosumers. ...
... More detailed results are shown for all 145 sub-regions globally aggregated to the nine major regions for Northeast Asia, Southeast Asia and India/SAARC (Fig. 4), Europe and Eurasia (Fig. 5), MENA and Sub-Saharan Africa (Fig. 6) and North America and South America (Fig. 7). Detailed information on all 145 sub-regions can be found in the respective publications [30,32,[40][41][42][43][44][45][46][47][48]. ...

Conference Paper
The global energy system has to be transformed towards high levels of sustainability for executing the COP21 agreement. Solar PV offers excellent characteristics to play a major role for this energy transition. Key objective of this work is to investigate the role of PV for the global energy transition based on respective scenarios and a newly introduced energy transition model developed by the authors at the Lappeenranta University of Technology (LUT). The available energy transition scenarios have no consensus view on the future role of PV, but a progressive group of scenarios present results of a fast growth of installed PV capacities and a high energy supply share of solar energy to the total primary energy demand in the world in the decades to come. These progressive energy transition scenarios can be confirmed by the LUT Energy system model. The model derives total installed solar PV capacity requirements of 7.1 – 9.1 TWp for today's electricity sector and 27.4 TWp for the entire energy system in the mid-term (year 2030 assumptions set as reference). The long-term capacity is expected to be 42 TWp and due to the ongoing cost reduction of PV and battery technologies, this value is found to be the lower limit for the installed capacities. The cost reductions are taken into account for the year 2030, but are expected to further proceed beyond this reference year. Solar PV electricity is expected to be the largest, least cost and most relevant source of energy in the mid-to long-term for the global energy supply.

Die nationalen und internationalen Energie- und Klimaziele erfordern tiefgreifende Veränderungen, einen strukturellen Wandel und rechtzeitiges politisches Handeln. Eine Vielzahl an Studien verschiedener Institutionen beschreibt Szenarien, in denen diese Ziele und eine weitreichende Dekarbonisierung erreicht werden können. Im Rahmen dieses Projekts wurden 36 Studien und insgesamt 57 Szenarien untersucht und entlang eines Katalogs an Kriterien systematisch ausgewertet. Die gesammelten Daten wurden in einer Datenbank aufbereitet. Die zentralen Ergebnisse werden in der vorliegenden Analyse beleuchtet.
