GCSE Physics - Biofuels #12

The video discusses biofuels, which are fuels made from recently living organisms, distinguishing them from fossil fuels. Biofuels are considered renewable and carbon neutral, as they absorb CO2 during growth. They are cost-effective and can be mixed with fossil fuels, allowing use without new infrastructure. However, biofuels pose challenges, such as land conversion, deforestation, and CO2 emissions from production processes. Despite these issues, biofuels can be a viable alternative to fossil fuels when used appropriately.
