Biofuel - GCSE Physics Definition

Biofuel refers to a type of renewable energy source derived from organic materials, also known as biomass, such as plants, animal waste, and even algae. These materials can be processed into a variety of fuels, including ethanol, biodiesel, and biogas, that are used to power vehicles, generate electricity, and provide heat.

Unlike fossil fuels, biofuels are considered more sustainable and environmentally friendly because their production and use result in lower net carbon emissions. This is because the carbon dioxide released during their combustion is offset by the CO2 absorbed by the plants during their growth.

As biofuels are part of the GCSE Physics curriculum, understanding their role in energy production helps students appreciate alternative energy solutions and the importance of reducing our carbon footprint.
