What are some examples of alternative fuels?
It depends upon who you ask and what you are asking about. When you are asking about electrical production we generally refer to “alternative energy” rather than “alternative fuel.” “Alternative” simply means different than what is normal. It does not necessarily mean “economical,” “renewable” or “sustainable.” As this is the alternative Fuel Vehicles section, if you are asking about vehicles then “fuel” probably means some form of energy carrier from another source. Ultimately Nuclear fusion on the sun is the source of all our energy except volcanic geothermal, tidal, and nuclear fission power. Traditional fuels are gasoline and diesel from crude oil. Alternatives would include: There is a process where gasoline or diesel can be made chemically from components in the air. It is only about 5% efficient.
