World Biofuel Day is celebrated on August 10 in remembrance of Sir Rudolf Diesel, who created the diesel engine. Biofuels are environmentally friendly fuels whose use would go a long way in reducing carbon emissions.

• On August 8, 1893, Sir Diesel successfully used peanut oil to run a mechanical engine for the first time.
• With this, he was able to foresee the possibility that fossil fuels could be replaced by vegetable oil as a practical source of energy in the coming century. 
• To commemorate this achievement, the date was chosen to observe World Biofuel Day and has been celebrated by the Ministry of Petroleum and Natural Gas since 2015.
