Renewable Energy comprises of 0.5 % Ethanol which is produced from crops like sugarcane and wheat. Ethanol is a clean-burning high-octane motor fuel and is used for heating purposes as well as in automobiles. However, as you can see the production of Ethanol is minor in comparison to the Energy production from Hydro power or Biomass.
The consumer need of sugar and wheat is first fulfilled in each country, and what ever is left over as the residue is further processed to Ethanol. Every year the US produces the highest amount of Ethanol in alignment to which it has started manufacturing flexible cars which can operate on Ethanol as well as “Gasohol”.
At the moment Ethanol is produced mostly from wheat and sugarcane. Progress is being made to enhance its products primarily in the USA.
