Ethanol fuel pros and cons alternative fuels like ethanol have become a significant source of fuel there are, of course. 2015 energy balance for the corn-ethanol industry : 1 investigates whether ethanol energy balance still improves and reviews some process energy sources. Ethanol fuel is renewable and sustainable being a renewable source of energy, the raw materials need sunlight for ethanol to be produced there are even companies that work on bypassing the harvesting of plant crops to produce ethanol.
Corn ethanol was first considered as a fuel source by harry ford and other auto-makers they predicted that ethanol would become the world's fuel supply. Compared with conventional unleaded gasoline, ethanol is a particulate-free burning fuel source that combusts cleanly with oxygen to form carbon dioxide and water use of ethanol, produced from current methods, emits a similar net amount of carbon dioxide but less carbon monoxide than gasoline. Ethanol fuel is cost effective compared to other biofuels ethanol fuel is the least expensive energy source since virtually every country has the capability to produce it corn, sugar cane or grain grows in almost every country which makes the production economical compared to fossil fuels.
Like all other fuels ethanol fuel also has certain advantages and disadvantages that will be more discussed throughout this article one of the most obvious advantages of ethanol fuel is the fact that ethanol fuel is a renewable energy source, meaning that is not exhaustible like the fossil fuels are.
