**We’d be better burning gas to charge the batteries in an electric vehicle - but let’s not use gas at all.** The [source](https://matter2energy.wordpress.com/2013/02/22/wells-to-wheels-electric-car-efficiency/) below is really well written blog. Goes into the maths. “Tank to Wheel” efficiencies: - Tesla claims 75%, the author suspects it’s more like 70% - Internal Combustion Vehicles are 16% Those numbers don’t take into account the losses from the original source of the energy. These do… “Well to Wheel” ( [[Embodied Energy]]) efficiencies: - Natural Gas → Generator → Transmission → Car Battery → Wheels = ~30-40% - For a conventional car this number is gated by the Tank-to-Wheel number, even if well-to-tank was 100% efficient. Altogether: > Very basically, if we took the gasoline you put into your car and burned that in a turbine, then sent that power to your electric car, the overall efficiency of the system would double. > > _**Double**_. **** # More ## Source [Wells to wheels: electric car efficiency](https://matter2energy.wordpress.com/2013/02/22/wells-to-wheels-electric-car-efficiency/) ## Related - [[Electric Motor Efficiency]] - [[I.C.
