I would need a source and a spreadsheet. No other energy source (other than nuclear) has the energy density of a fossil fuel. Fossil fuels are also incredibly stable to store and handle. This means refueling can be done very efficiently. Charging electric cars for long range use is not at all convenient, yes, this gets to your battery technology argument. The power infrastructure to allow every car to be electric is virtually impossible to build, **especially** if you feel the grid has to be green as well. In a cold climate, EV range is cut almost in half, due to running the electric heater, while ICE vehicles use the waste heat of combustion to warm the cab. The manufacturing of EV is also much more toxic to the environment than ICE vehicles. I would be interested to see more categories to compare ICE to EV.
