**5. Conclusion**

The production of alcohol fuel has gradually increased and become an important industry in various countries such as the United States, Brazil, and China. Methanol was produced from biomass or coal and natural gas while ethanol is mainly produced from food crops or sugarcane molasses by fermentation process. So that, rural area's sugarcane industry is one of the major industrial corridors, meanwhile the agriculture economy was increased and generates employment for more people by the collaborating with sugar industry either directly or indirectly.

After production of methanol or ethanol, it was blended with petrol/gasoline in different proportion like E10 considered as low-level ethanol blends and E85

considered as high-level ethanol blends. Day to day, the usage of alcohol fuels has been rapidly increased due to their positive impacts such as reducing GHG emissions, reduction in the emission of toxic gases, and helping to mitigate climate change. Likewise, it has an impact on sustainable development in economic, social and environmental aspects. Therefore, alcohol fuel can be used as best transportation fuel instead of gasoline, but it is still years far away from extensive adoption. More researches and improvements are necessary if we are to use alcohol as a fuel of the future.
