This online visualization was developed in 2014 by Elioth, to popularize the concept of urban metabolism for policymakers, project leaders and citizens, by showing how energy, material and water flows are set in motion to support the life of the city : how much electricity, gas, oil, heat, consumer goods, food, and water enter Paris each year? Does the city export more goods than waste? How dependent is the city from energy imports? Is self-sufficiency possible for such a big city ?
