Only about 12%–30% of the energy from the fuel you put in a conventional vehicle is used to move it down the road, depending on the drive cycle. The rest of the energy is lost to engine and driveline inefficiencies or used to power accessories.| www.fueleconomy.gov
EVs are 60% to 73% efficient, depending upon drive cycle (77% to 100% efficient if the energy recaptured from regenerative braking is counted).| www.fueleconomy.gov
