Introduction –   World Biofuel Day is celebrated annually on August 10 to highlight the importance of biofuels that are produced from algae, agricultural waste, animal waste, and industrial waste in our daily lives. Biofuel is produced in a short time, either in gaseous or liquid form, and is sustainable, environmentally friendly, biodegradable, and renewable

Biofuel is a fuel that is produced in a short time from the biomass and is preferable to the slow natural process, which involves in the formation of fossil fuels such as oil. Biofuel may be produced from domestic, industrial, or agricultural biowaste and plants. Biofuels are mainly used for transportation, but they can also be used to generate electricity and heat. It is produced in a short time in either liquid or gaseous form. Biofuels are renewable, sustainable, environment-friendly, and biodegradable.

History – World Biofuel Day is observed annually on August 10 to honor German inventor, Sir Rudolf Diesel, who discovered the diesel engine and ran his engine by using peanut oil in the year 1893. Sir Rudolf Diesel was the first individual, with his remarkable experiment, to predict that the possibility of vegetable oil would replace fossil fuels. Thus, this international day is celebrated on August 10 annually to highlight their achievement.

Significance – Biofuels are used in reducing the dependence on crude oil and promote a clean green environment that is good for your health. The use of biofuels also generates employment in rural areas with additional income. It will lower carbon emissions. which meet the requirements of energy in the 21^st century. Biofuels are also used to fulfil and enhance the demands of transportation in big cities. This global day celebrates the activities of the government to develop and strengthen the biofuel sector in our country. The main purpose of this international day is to promote the use of biofuel by governments that help to reduce dependence on crude oil and encourage a green environment worldwide.
