Abstract Future smart cities metrics have complex and interdisciplinary targets. Energy portfolio and the ratio of self-consumption / sufficiency are key performance indexes for city long-term sustainability. Targeting 100% renewables production for mitigating climate change threats ask also for challenging solutions. As Europe is not enjoying the Sunbelt climate but still showed clear commitment towards high renewables penetration, the paper addresses the feasibility of a scenario targeting electrical energy production with 100% renewables and complete self-sufficiency in the so-called Sub-Sunbelt region. A preliminary study, for specific cities in the Sub-Sunbelt region, is analyzed in terms of key performance indexes related to renewables production and self-sufficiency. For this, selected cities from the Sub-Sunbelt region (from 35° to 50° latitude north) in Greece, Italy, Spain, Portugal, Romania, Austria, Germany and France have been chosen, by also making a comparison with sunny Sunbelt based cities Rabat, Dubai and Cairo. The study suggests that self-sufficiency and resilience with solar based renewables is reachable in Sub-Sunbelt regions, and that important renewables-based H2/CH4 long-term storage and consumption resources are also needed, while the Sunbelt regions can become exporters of renewables-based H2/CH4 by using their surplus energy during the summer time. © 2019 IEEE.
