Low Energy: Estimating EV Electricity Use - Working Paper vs Peer Review

We provide the first at-scale estimate of electric vehicle (EV) home charging. Previous estimates are either based on surveys that reach conflicting conclusions, or are extrapolated from a small, unrepresentative sample of households with dedicated EV meters. We combine billions of hourly electricity meter measurements with address-level EV registration records from California households. The average EV increases overall household load by 2.9 kilowatt-hours per day, less than half the amount assumed by state regulators. Our results imply that EVs travel 5,300 miles per year, under half of the US fleet average. This raises questions about transportation electrification for climate policy.  - National Bureau of Economic Research

Editor's Note: ​This is a excellent example of why a working paper is NOT a peer-reviewed paper.  The researchers did not measure vehicle miles traveled.  They did not determine if the sample population was installing solar at the same time.  They did not account for charging away from home.  They did not determine if there were energy use changes in the home.  

Yet, the authors drew conclusions.  This probably won't make it past peer-review without heavy editing.... which will destroy most of the conclusions.
