According to a recently published scientific study, delivery by drone requires up to 94% less energy than delivering the same package by a diesel-powered van. Even a small electric car is less economical per delivered package than a drone. Only an electrically powered cargo bike is slightly more energy efficient.

Energy model

The results of the study were published in the scientific journal Cell. According to the researchers, there is an increasing need for knowledge about the energy requirements of drone-based delivery methods compared to other delivery methods such as large and small delivery vans, electric cars, and electric cargo bicycles.

Therefore, the researchers created a database containing data from 188 drone delivery flights, varying package weight, flight speed, and altitude. The average distance was 2 km as the crow flies. An energy model was then made based on that data, so the results could be compared with regular delivery options.
