How do bio alcohol work as a fuel?

Bioalcohols, primarily ethanol and methanol, are produced through the fermentation of biomass, such as crops and agricultural waste. They serve as renewable fuels by undergoing combustion in engines, releasing energy while emitting fewer greenhouse gases compared to fossil fuels. Bioalcohols can be used alone or blended with gasoline, enhancing octane ratings and improving engine performance. Their production and use contribute to reducing reliance on fossil fuels and promoting sustainable energy practices.
