Green fuel refers to environmentally friendly and sustainable energy sources that reduce the carbon footprint and minimize environmental impact. Derived from renewable resources like biomass, algae, and organic waste, green fuels aim to replace traditional fossil fuels. One notable example is biodiesel, produced from plant oils or animal fats, offering a cleaner alternative to conventional diesel with lower greenhouse gas emissions. Similarly, bioethanol, derived from crops such as corn or sugarcane, serves as a greener substitute for gasoline. Hydrogen, when produced through renewable methods like electrolysis using wind or solar power, is another crucial green fuel. These alternatives contribute to mitigating climate change by curbing dependence on finite fossil fuels and promoting a more sustainable energy landscape, aligning with global efforts to transition towards eco-friendly and carbon-neutral energy solutions.
