How much more efficient can a car become ? It’s not as much of a change as going from horses to cars.

Average efficiency of a car in 1970 was 11 MPG. Today we are at an average of 25 MPG (and that's only because gas is still too cheap) and many non-electric cars get up to 40 MPG. Newer electric cars like the Model 3 are at about 130-150 MPG.

As the transition to electric cars accelerates, our energy use will see a significant decline. Transportation makes up 35% of our total energy use in the US. Going from an average of 25 MPG to a conservative 50 MPG will have major impacts on our energy sector.

Electric cars are only a fraction of transportation energy costs. Electric trailer trucks and electric airplanes are far less feasible because of the poor energy density of batteries.

I’m also talking about the cost of the car itself. Sure there are improvements but they are not improving at the rates they used to.

An electric car is still too expensive for a lot of people around the world.
