But with Advantages come disadvantages. Some disadvantages of biofuels are that it can be difficult to collect and grow a lot of fuels at once. Another disadvantage of biofuels is that burning biofuels makes greenhouse gasses like fossil fuels. Also, Waste materials from biofuels are not available all year. While some consider their use "carbon neutral," the machniery required to farm the plants for biofuels does create carbon emissions, this machinery is also typically not powered by biofuels. Research suggests despite this fact, that biofuels help to reduce carbon emissions by 50-60%.Biofuel production is closer to being carbon-neutral than using fossil fuels.
One of the main detractors to the use of biofuels is that setting aside land for biofuel crops means less land for food production. Some foreign countries have said that it is unethical to use crops for biofuel when global hunger is an ever present problem.
In conclusion, Biofuels are a type of fuel made from living things or their waste. If you were to use biofuels in a vehical, they would be called biodeisel and biothanol. Biofuels are made from crops. Biofuels are not carbon-neutral.
