Solar Power Potential of City Linked to Its Roadways

New study finds links between a city's solar potential and it's road systems. 

As reported by Charles Q. Choi of IEEE Spectrum:

Inspired by studies on the relationships between blood vessel networks and a body's size and metabolic rates, study author Sara Najem, a physicist at Lebanon's National Center for Remote Sensing in Beirut, investigated what connections might exist between different elements of a city's infrastructure, such as its road network and its solar potential. "I am always seeking to draw analogies between living systems and cities," Najem says. Najem will detail her findings in the journal Physical Review E. 

Najem analyzed the road networks and the number of buildings in 10 cities: Beirut; New York; Boston; San Francisco; Boulder, Colorado; Cambridge, Massachusetts; Portland, Oregon; Washington, D.C.; and Vitacura and Lo Barnechea in Chile. She simulated the amount of sunlight rooftops in these cities received based on the footprints of their buildings and their elevations, areas and topography.
