With the increasing global demand for energy and growing concerns about climate change, the search for sustainable and environmentally friendly energy sources has become a critical priority (John et al. 2025). Biofuels, derived from biological materials such as plants, algae, and organic waste, have emerged as a promising alternative to fossil fuels (Ameen et al. 2022a). Among various renewable energy options, biofuel production stands out due to its potential to reduce greenhouse gas emissions, support rural economies, and ensure energy security. This chapter is focused on the best methods of biofuel production, analyzing their efficiency, environmental impact, and technological advancements. By understanding the strengths and limitations of different biofuel production techniques, we can move closer to a cleaner, more sustainable energy future (Rozina et al. 2022).
