City-integrated renewable energy for urban sustainability

Science - Urban PlanetJuly 2016: A recent issue of the journal Science published a number of articles around the theme Urban Planet.  One of the papers published was entitled: City-integrated renewable energy for urban sustainability (link to full text). The paper takes a high-level overview on a range of key carbon reduction opportunities at the city-level.

“To prepare for an urban influx of 2.5 billion people by 2050, it is critical to create cities that are low-carbon, resilient, and livable. Cities not only contribute to global climate change by emitting the majority of anthropogenic greenhouse gases but also are particularly vulnerable to the effects of climate change and extreme weather. We explore options for establishing sustainable energy systems by reducing energy consumption, particularly in the buildings and transportation sectors, and providing robust, decentralized, and renewable energy sources. Through technical advancements in power density, city-integrated renewable energy will be better suited to satisfy the high-energy demands of growing urban areas. Several economic, technical, behavioral, and political challenges need to be overcome for innovation to improve urban sustainability.”
