"Alternative fuel" is an imprecise term that seeks to contrast certain fuels with what might called traditional fuels. Traditional fuels would include coal, oil, gas, and wood as a few examples. It is not possible to produce a definitive list of products but here are some suggestions.
Carbon based alternative fuels might include ethanol from bio-mass, recycled bio-mass from agriculture or forestry operations, peat dug from soils rich in organic matter.
Non carbon based alternative fuels include solar energy used to produce electricity or hot water, wind, waves, tidal energy, hydro-electric, hydrogen and more.
Nuclear power can sometimes be considered to be an alternative energy source or a traditional one.
i think that's she thinks is why do they have to have alternative fuels that's just watse of time
No. Alternative energy means energy sources other than fossil fuels.
Alternatives fuels are fuels that are not made from fossil fuels (coal, oil and natural gas).
Biofuels, Algae fuels ect.
Electricity
Yes, there are several alternative fuels that can be used as substitutes for oil, such as natural gas, biofuels (like ethanol and biodiesel), hydrogen, and electricity. These alternative fuels can help reduce greenhouse gas emissions and dependence on traditional fossil fuels.
There are several alternative fuels for a diesel engine. Some alternatives include Biodiesel and vegetable oil.

There aren't many cars powered by alternative fuels because some cost more and are hard to make and other fuels don't get you very far.
