Foundations of Biofuels and Fossil Fuels

Definition of biofuels and production pathways

Transport accounts for a large share of energy use, and the choice between options matters for economy and climate. Biofuels are fuels derived from biomass—plants, wastes, and residues—that can replace or supplement traditional petrol and diesel. Production pathways include fermentation to ethanol, transesterification to biodiesel, gasification to synthesize fuels, and anaerobic digestion to yield biogas. Fuel choices matter!

• Fermentation to ethanol
• Transesterification to biodiesel
• Gasification to syngas and Fischer–Tropsch fuels
• Anaerobic digestion to biogas

In South Africa, feedstocks like sugarcane, maize, and sunflower support local biofuel projects, aligning with the biofuels vs fossil fuels pdf discussion of renewables, carbon balance, and practical deployment. Fossil fuels are energy-dense hydrocarbons—crude oil, coal, and natural gas—formed over millions of years and extracted via drilling and mining, then refined into gasoline, diesel, and other products.
