How Will We Meet the Energy Demands of the Coming Megacities

05.08.2015 | Singularity HUB | www.singularityhub.com

Odds are you live in a city. In fact, more than half the world today lives in cities and by 2050, it's expected that two-thirds of the world will be residing in cities.

While smaller cities struggle to modernize to support the influx of people, who are often poor and looking for work and essential services, the scale of need for megacities (defined as 10+ million people) is at least an order of magnitude in difference. In the last 25 years, the number of megacities in the world has grown from 10 to 28, home to nearly half a billion of the human race. By 2030, the number is expected to increase to 41.

Megacities are rising

But the rise and swell megacities will come at a price: energy needs will be enormous. How those needs are met will have significant and potentially detrimental effects on the environment. Today, things look dire-even though 6.7% of the global population currently live in megacities, their energy demand produces 12.6% of world's solid waste.

Speaking at a recent Executive Program hosted by Singularity University, Faculty Chair of Energy & Environmental Systems Gregg Maryniak suggested a progressive solution to the energy demands of the coming megacities: space-based solar power.
