These people point out that it's also not that you must plug it in, but that you can plug it in, and that makes a huge difference. If you can plug it in, you don't have to use electricity that comes from coal-fired plants.
Hybrid cars are unlike battery electric vehicles because the batteries used in hybrid cars do not have to be charged by an external source. Instead, in order to get a charge, kinetic energy is generated by way of regenerative braking. Furthermore, some hybrid cars make use of their own combustion engine to create electricity. The combustion engine does this by spinning an electrical generator. The spinning does one of two things. It can either recharge the battery or in a more direct way, it can give power to an electric motor. This motor is what then drives the vehicle.
So in the event that we have an energy crisis, Americans should really use the time to bond and create a unified fight against conflict over oil in U.S. Hybrids cars are the way to beat the energy crisis, and if the the countries still start to fight each other over oil, at least America will know they tried to stop things by investing in hybrid cars.
A hybrid cars battery can run out
