Most liquid fuels in widespread use are derived from the fossilized remains of dead plants and animals by exposure to heat and pressure in the Earth's crust. However, there are several types, such as hydrogen fuel (for automotive uses), ethanol, jet fuel and biodiesel which are all categorized as a liquid fuel.
Fossil fuels are an incredibly dense form of energy, and they took millions of years to become so. And when theyâre gone, theyâre gone pretty much forever. Itâs only a matter of time. There are three different types of fossil fuels â oil, gas and coal. Clearly, our reserves of these are finite - it's a matter of when they run out - not if.
