I recently switched to an electric car and I've read a justifiably heated debate online about electric vehicles. So in this short video, we'll start with the physics of the two engines and the energy that powers them. Then, since many are wondering whether an electric car is worth it, we'll do a numerical comparison between car purchase, road tax, maintenance, and fueling. Let's look at the physics of the two engines. In a combustion engine, we start with the chemical energy of the fuel—gasoline or diesel—that is burned. This chemical reaction, called combustion, releases energy in the form of heat. The gases inside the engine heat up, expand, and push the pistons... and that's how kinetic energy is generated; the car moves! In an electric motor, the battery provides us with electrical energy that is transformed into mechanical energy using the laws of electromagnetism. That is, the interactions of currents and magnets inside the engine become turning axles, moving wheels, and kinetic energy! Let's look at the physics of energy. Thermal cars have an overall efficiency of 15-30% *yes, because the remaining 70% or more is wasted*; electric cars have an efficiency of 75-85%. What does that mean? When it comes to electric cars, we're used to thinking in kilowatt-hours, which is a unit of measurement for energy, so let's make this comparison. In Italy, 1 kWh of gasoline costs about 20 cents, and 1 kWh of electricity about 25 cents. So the advantage of electric cars isn't that energy costs less, it's simply that you can travel much further with that kilowatt-hour. Now let's look at the 4-point comparison: car purchase, road tax, maintenance, and refueling.
