create tons of pollution transporting and refining it, to finally waste 70% of it burning it in our cars when we could simply use that electricity directly to power electric vehicles, eliminating the pollution from refining and burning oil in inefficient internal combustion engines. It is obvious ...
Coal is the dirtiest fuel of them all. Most of the energy in coal comes from combining carbon with oxygen to make carbon dioxide. And coal plants are notoriously inefficient; even the most modern ones (supercritical combustion) produce electricity at only 43 percent efficiency. In contrast, mode...
The motor simply turns but since it is being turned by the wheels, it is generating electricity. If you apply this energy to a load such as a resistor, it is converted to heat and there is a corresponding resistance to motion at the motor shaft (like a brake). In a hybrid vehicle, ...
