The use of plug-in electric vehicles in ride-hailing services is expected to have substantial emission reduction benefits. However, these benefits depend on the energy fuel mix in the grid and vehicle usage. Here we employ high-resolution data from Uber and Lyft in California to provide insights into the use of electric vehicles in ride-hailing. The growth in electric vehicle use has been rapid in the past two years and a proportionally small number of electric vehicles are already using a large share of electricity provided by the public charging infrastructure. Concerns about the ability of electric vehicles to provide the same level of service as gasoline vehicles has been overstated: we found no statistical difference between the two technologies for services provided to ride-hailing companies. Lastly, the potential environmental and emission reduction benefits are approximately three times higher for electric vehicles being used in ride-hailing compared with those of regular vehicle usage in California.

预计在乘车服务中使用插电式电动汽车将带来巨大的减排效益。但是，这些好处取决于电网中的能源燃料组合和车辆使用情况。在这里，我们使用来自加州Uber和Lyft的高分辨率数据，以深入了解电动汽车在乘车服务中的使用。在过去的两年中，电动汽车的使用量一直在快速增长，并且已经有相当一部分电动汽车使用了公共充电基础设施提供的大部分电力。人们对电动汽车提供与汽油汽车相同水平的服务能力的担忧被夸大了：我们发现，为乘车公司提供的两种服务技术之间没有统计差异。最后，
