Biofuels

Biofuels, derived from living matter, are alternatives to fossil fuels like petrol and diesel. They are produced by fermenting crops such as corn and sugar cane. While biofuels are cost-effective and can offset greenhouse gas emissions, their production can also lead to environmental and socioeconomic issues, such as pollution from fertilizers and increased food prices. The debate between using crops for food or fuel is ongoing. Future advancements, like second-generation biofuels, may offer more sustainable solutions by utilizing crop waste. Balancing environmental impacts and food needs is crucial for biofuels to become a truly green energy source.

What are biofuels primarily made from?
