What is "alternative fuel"?

Alternative fuel refers to any fuel other than gasoline or diesel that is used to power vehicles. These fuels include electricity, hydrogen, natural gas, propane, ethanol, and biodiesel. They are often considered better for the environment because they can produce fewer harmful gases and reduce the use of oil-based fuels. Some alternative fuels, like electricity and hydrogen, can power vehicles without releasing harmful gases, while others, like ethanol and biodiesel, are made from renewable sources, helping to lower dependence on nonrenewable fuels.
