Why is ethanol not widely used for vehicles all around the world?

Well, it isn't as efficient, it only works in some cars and the USA made a deal with OPEC years ago that said we wouldn't. We promised not to research alternative fuels in exchange for a promise to always keep us fully supplied with oil. So, in order to switch from fossil fuels to alternative sources we would have to find a more efficient fuel, build a lot of new types of cars to use it and fight OPEC and American oil companies every step of the way. Those companies don't want to lose the money they are making and they have a lot of pull in Washington right now. But, buses in China run on natural gas, there are a lot of cars in Australia that use liquid propane and here in the US we have electric and solar cars in the south-west and California and a lot of bio-diesel in Hawaii. So, there are other options out there and people are using them.
A:Because it takes more energy to PRODUCE ethanol (in the form of diesel fuel in tractors and combines used to grow the corn) than you can get FROM the ethanol. We have to find smarter ways of producing biofuel, that isn't taking the food out of the mouths of the poor. A:It takes way too much land to be a real resource. If the US switched to ethanol the amount of land it would take to produce the corn would cover an area the size of the entire northeast down to Ohio assuming that we don't use the fuel to make the corn and we can grow crops all year round and that no natural disasters will occur such as a hailstorm or flood which would devastate the crop.Wiki User

∙ 12y agoBritain is not a major producer of cotton. Since they cannot produce or import the corn needed to supply ethanol cost effectively, it would not be logical for them to use ethanol to fuel their cars.

What is ethanol used for?
Ethanol is used for fuel, or other various things.(That is not an answer!)Ethanol is a biofuel. BIOFUELS are widely considered a way to reduce greenhouse gases from fossil fuel use and thereby reduce human-caused global warming.Although ethanol is a common form of alcohol, the largest single use of ethanol is as a motor fuel and fuel additive.Compared to petrol, ethanol cuts poisonous gas emissions (carbon monoxide, nitrous oxides, sulfur dioxide) and produces fewer greenhouse gases that cause global climate change. Added to petrol, ethanol also reduces ground-level ozone formation by lowering the poisonous emissions from petrol combustion.Ethanol is made by fermenting and then distilling starch and sugar crops -- maize, sorghum, potatoes, wheat, sugar-cane, even cornstalks, fruit and vegetable waste.Many countries produce ethanol - the main ones being: Brazil, United States of America and China.Today, almost half of Brazilian cars are able to use 100% ethanol as fuel produced from domestically grown sugar cane. But environmentalists warn that the demand for sugar cane is a disaster for the Amazon rain forest as huge areas are cleared for agricultural use.Expanding large-scale agriculture to grow sugarcane, critics say, will worsen the loss of species diversity, water-quality problems, and habitat fragmentation in some of the world's most biologically diverse regions.Other opponents, environmentalists and livestock farmers say that increased ethanol production won't meet energy goals and may damage the environment, while at the same time causing worldwide food prices to soar as food crops are turned into ethanol.Other researchers report that the production of ethanol consumes more energy than it yields.One of the advantages of producing ethanol is very little is wasted. With sugar cane, for example, the leftover pulp is utilized in power plants as a surprisingly efficient fuel to produce electricity.Use these links for more information about Bioethanol:http://www.sciencenewsforkids.org/articles/20060412/Feature1.aspCrops as an Energy Source-Bunneh
