使用自动化无人驾驶飞行器（无人机）运送商业包裹有望成为一个新的行业，大大改变货运部门的能源使用。在这里，我们发现目前的电池技术的多直升机的实用范围约为4公里，需要一个新的城市仓库或停靠站网络作为支持。我们发现，尽管无人机每包装公里消耗的能源比送货卡车少，但所需的额外仓库能源和无人机每包装行驶的更长距离大大增加了生命周期的影响。尽管如此，在大多数情况下，小型无人机包裹递送的影响低于地面递送。研究结果表明，如果精心部署，无人机送货可以减少货运部门的温室气体排放和能源使用。为了实现无人机交付的环境效益，监管机构和公司应该专注于最大限度地减少额外的仓储和限制无人机的大小。使用无人机运送商业包裹有望成为一个新的行业。在这里，作者表明，当无人机的尺寸和额外的仓储要求受到限制时，用无人机取代卡车送货可以减少温室气体排放和能源使用。
The use of automated, unmanned aerial vehicles (drones) to deliver commercial packages is poised to become a new industry, significantly shifting energy use in the freight sector. Here we find the current practical range of multi-copters to be about 4 km with current battery technology, requiring a new network of urban warehouses or waystations as support. We show that, although drones consume less energy per package-km than delivery trucks, the additional warehouse energy required and the longer distances traveled by drones per package greatly increase the life-cycle impacts. Still, in most cases examined, the impacts of package delivery by small drone are lower than ground-based delivery. Results suggest that, if carefully deployed, drone-based delivery could reduce greenhouse gas emissions and energy use in the freight sector. To realize the environmental benefits of drone delivery, regulators and firms should focus on minimizing extra warehousing and limiting the size of drones. The use of drones to deliver commercial packages is poised to become a new industry. Here the authors show that replacing truck delivery by drones can reduce greenhouse gas emissions and energy use when the drone size and additional warehousing requirements are limited.
