Explain how biofuel is better than fossil fuels.
Biofuels are better than fossil fuels in several ways. Firstly, biofuels contain higher hydrogen and oxygen and less carbon compared to fossil fuels. This composition improves the combustion of biodiesel and reduces particulate emissions from unburnt carbon, making them cleaner burning fuels.
Secondly, biofuels are produced from biological products such as living organisms or waste generated from biological products. This makes them a renewable source of energy, unlike fossil fuels which are non-renewable. Additionally, biodiesel can be directly used in regular diesel engines without making any changes or modifications to the engines.
Biotechnology offers viable options for biofuel production as it is environment-friendly and uses natural systems, providing a sustainable alternative to fossil fuels.
Explanation
The answer draws from multiple sections of the textbook context. The first paragraph uses information about the chemical composition of biofuels (higher hydrogen and oxygen, less carbon) and its environmental benefits. The second paragraph highlights the renewable nature of biofuels and the practical advantage of biodiesel being compatible with existing engines. The third paragraph references the broader context about biotechnology offering environment-friendly alternatives to non-renewable fossil fuels.
