This is how cities in the future will get their energy

In the global effort to fight climate change, cities have some of the greatest potential– and the greatest imperative — to make a difference. With an increasing global migration into the world’s urban areas, which are expected to support at least two-thirds of the total human population by 2050, experts have argued that cities have no choice but to transition toward low-carbon systems if they’re going to remain sustainable.

Energy will need to be a primary focus of that effort. From the expansion of renewable energy sources to the adoption of cutting-edge energy efficiency and storage technologies, cities have the opportunity to drastically reduce their carbon footprints.

This is the focus of a new paper, published Thursday in the journal Science, that discusses the ways cities can integrate renewable energy, as well as energy-saving technologies, into the urban landscape. This can be a challenge, given that cities — with their closely packed buildings and dense populations — don’t always lend themselves to traditional renewable techniques. It’s not exactly practical to fit an acres-long solar panel array in the middle of Shanghai, for instance, or to place a 200-foot-tall wind turbine in downtown New York City.
