What is the most commonly used alternative fuel?

Question

And I would be grateful if u can tell me what it is used for. Thanks for your help!

Answer 1

There are three commonly used alternative fuels: ethanol, biodiesel, and methane.

Ethanol can be produced by fermentation of sugar from crop plants such as sugar cane or corn. Someday it will probably be produced in large amounts from other plant materials. It is a direct substitute for gasoline. Put it in the gas tank of your car and drive away.

Biodiesel is basically vegetable oil. Small diesel engines can be slightly modified to run on the vegetable oil collected from the deep fat fryers of restaurants! Too bad we don't eat a lot more fried food or we could run a lot of cars this way. Right now there is not nearly enough vegetable oil to supply the demand for diesel fuel.

Methane is cooking gas, like in your stove or water heater in your house. THere are thousands of cars and even buses in the USA and other countries that have been modified to run on methane. In a city near me all the cars that belong to the gas company have been modified this way - I think it's about 300 cars and trucks. Methane comes mostly from oil wells, but it can be made from sewage, garbage or wood scraps. However, although we know how to do that, it is still less expensive to buy gasoline. However, if the price of gasoline increases another dollar or two, then it will make sense to use these alternative fuels much more.

Well, most people probably don't know this, but there are thousands of electric cars on the road here in the USA. Here's a website where you can see several hundred EV owners and their cars:

If you count off-road 'fleet' electric cars, golf carts, airport people movers, hi-los, etc, I think electricity is the winner. Also, don't forget subway trains!
