ong>Answer:A biofuel is a FUEL that is produced through contemporary processes from biomass, rather than a ... and TECHNICAL issues relating to biofuels production and use, which have been debated in the popular media and scientific journals.

Explanation:Advantages

Blending petrol or diesel with biofuels can have noticeable advantages. Although biofuels aren’t as efficient or powerful on their own, when they’re blended with conventional fuels they can improve performance and fuel economy. Some biofuels are derived from plants, which will have reduced the amount of carbon dioxide in the air. However, the benefit might not be as high as you might think, considering the fertilisation, transportation and manufacturing costs that have gone into the process.

Another advantage of biofuel is, in many cases, a lower cost. Ethanol TENDS to be cheaper than petrol, so blending the two successfully could be cheaper. Biofuel is renewable, too, as creating more simply requires more plants grown or more natural waste. Oil supplies - and therefore petrol and diesel - will eventually run out, pushing up prices in the future. Biofuel should remain cheap as it’s easier to PRODUCE and plentiful.

Biofuels can ALSO be produced locally, leading to an increase in jobs and a reduction in transportation emissions.

Disadvantages

No fuel is perfect, and there are some biofuel disadvantages - especially if plants are grown specifically. Biofuel production is currently equivalent to just a tiny fraction of global energy demand, which means a huge amount of land, water and fertiliser is needed. The land used for biofuel production could also be used for crops and food production, while the oils needed may come from rainforests and other endangered habitats.

If you’re planning to use biofuel for cars or goods vehicles, make sure the biofuel is good quality. Poor fuel can lead to a lot of problems, including engine blockages and corrosion. In colder weather, biofuel can sometimes become waxy.
