Using delivery drones in cities consumes MORE energy than vans, according to new research

A new study has found that using delivery drones in dense urban environments might actually consume more energy than a conventional delivery van. Thomas Kirschstein, an economist at Martin Luther University in Halle-Wittenberg, Germany, developed a simulation to compare how energy efficient different delivery methods would be in a large and crowded city. He compared a delivery drone, electric van, and diesel van as they traveled through a digital recreation of Berlin to see which required the least amount of fossil fuel to complete equivalent delivery routes. The clear winner were electric vans, which consumed more than 50 percent less energy than diesel vans. The biggest surprise, however, came from drones, which turned out to be the most energy hungry of all the delivery methods, consuming as much as 10 times the amount of energy that the electric vans did.
