We modeled how much energy drone delivery would use, and how it would be different from the ways packages are delivered now. Reducing the need for trucking by delivering some packages with electric drones could save fuel, and potentially carbon emissions. About one-quarter of transportation emissions, the equivalent of 415 million metric tons of carbon dioxide, comes from medium- and heavy-duty trucks, the kinds of vehicles that deliver freight to warehouses, businesses and consumers’ homes. But transportation is still largely powered by fuels made from oil and is now the largest source of greenhouse gas emissions in the U.S. electricity sector has been rapidly transitioning to generating power with fewer greenhouse gas emissions. But in other cases, using trucks – especially electric-powered ones – would be more efficient and cleaner. We found that in some cases using electric-powered drones rather than diesel-powered trucks or vans could reduce energy use and greenhouse gas emissions. uses energy, and the resulting environmental effects. Our new research has measured how that shift would change how the U.S. Companies including Amazon, UPS, Google and DHL are already exploring ways to deliver packages with drones instead of trucks. Most of them belong to people flying them for fun, but a growing number are used commercially. There are more than 1 million drones registered in the U.S.
