Scientists applied a model where rooftop PV and electric vehicle batteries are integrated into the energy system of nine Japanese cities. Their findings suggests that such a system could meet more than half of every city's total energy demand by 2030, and as much as 95% in some cases. The model also reveals opportunities to cut both pollution and energy costs for urban populations in Japan.A new study from Japan develops a model for cities to maximize their use of rooftop PV electricity, using the batteries in electric vehicles to balance the grid. Applied to nine different Japanese cities (Kyoto, ...Den vollständigen Artikel lesen ...
