Compared with cars, SUVs consume more energy per vehicle mile. Consequently, SUVs emit more carbon dioxide per vehicle mile than do cars. However, in the United States, the typical occupancy is higher for SUVs than for cars. The issue of interest in this study was the resultant energy usage per occupant distance. In other words, does the higher occupancy of SUVs compensate for their higher energy consumption per vehicle distance when considering energy consumption per occupant distance? The analysis used the following data for cars and for SUVs: Average real-world vehicle fuel economy for model year 2017 vehicles (based on the information from the Environmental Protection Agency ) Average vehicle occupancy in 2017 for privately operated household vehicles (from Oak Ridge National Laboratory ) The results are shown in the table below. Sivak occupancy The final step of the analysis (with the results shown in the last row of […]
