Biofuels are alternative fuels derived from renewable biological resources, typically plant-based materials or animal waste. They are considered a sustainable and environmentally friendly substitute for fossil fuels, as they have lower net carbon dioxide emissions and contribute to reducing greenhouse gas emissions.

Biofuels can be broadly categorized into two main types: ethanol and biodiesel. Ethanol is produced by fermenting and distilling crops with high sugar or starch content, such as corn, sugarcane, or grains like barley and wheat. Biodiesel, on the other hand, is made through a chemical process called transesterification, which converts vegetable oils, animal fats, or used cooking grease into a fuel suitable for diesel engines.

These renewable fuels have gained significant attention in recent years due to their potential to reduce dependence on fossil fuels, decrease greenhouse gas emissions, and promote energy security. Biofuels are a key component in efforts to achieve a more sustainable and low-carbon transportation sector.
