Why is powering an electric car via electric from fossil fuels better than powering a vehicle with fossil fuels directly?
In: Technology
Because eletcric cars are significantly more energy-efficient than gas cars are. Whereas gas cars [manage about 12-30% tank-to-wheels efficiency, electric cars manage 77% grid-to-wheels efficiency](https://www.fueleconomy.gov/feg/evtech.shtml). While this metric is somewhat overstated because the losses in fuel conversion have already taken place before it reaches the grid, a caomparison of carbon intensity per mile [shows that electric vehicles still end up with a significantly lower per-mile carbon footprint](https://www.ucsusa.org/sites/default/files/attach/2015/11/Cleaner-Cars-from-Cradle-to-Grave-full-report.pdf).
