Advantages of using ethanol as fuel

A. It is a carbon-neutral activity

C. It does not produce toxic gases when burnt

D. It can be mixed with conventional petrol to make gasohol

Disadvantages

B. It takes a lot of plant materials to produce the ethanol

Explanation:

It has been proven that blending ethanol with conventional petrol produces gasohol and this helps to reduce the harmful emissions of CO, hydrocarbons, etc. This then means that vehicles that run on ethanol produces fewer harmful emissions than those that run on gasoline. For ethanol, it produces a no net carbon dioxide emissions.

Ethanol is considered to be atmospheric carbon neutral when the combustion of ethanol is made from biomass (such as sugarcane and corn). Ethanol is made plant materials like grains and crops that possess high starch. Also, it can be made from sugar content such as sugar cane, sorghum, corn, barley and sugar beets.
