What are the differences types of biofuel?How are they useful.
Answers
Answer:
Unlike other renewable energy sources, biomass can be converted directly into liquid fuels, called "biofuels," to help meet transportation fuel needs. The two most common types of biofuels in use today are ethanol and biodiesel, both of which represent the first generation of biofuel technology.

We mainly survive on fossil fuel, which is fuel that took millions of years to form. Fossil fuels are geologic deposits that are buried deep underground. They were developed from decayed plants and animals and converted to natural gas, heavy or crude oils. When exposed to pressure and heat from the earth’s core for hundreds of millions of years.
The unfortunate part is that at the rate the world’s population is growing, we are fast depleting fossil fuels, and they are not replenishable in our lifetime. The only solution that remains is to turn to alternative and renewable energy solutions such as biofuels.
Biofuel is fuel that is derived from biomass or algae and plant material and animal waste. Since biomass is replenishable, biofuel is a source of renewable energy, unlike natural forming fuels such as coal, natural gas, and petroleum.
Types of Biofuel
There are three common types of biofuels, which include:
1. Ethanol
Ethanol is pure alcohol or ethyl alcohol and is probably the most common alternative biofuel used in motor vehicles today. Ethanol can be made using different sources, but the most commonly used are sugarcane and corn. IN 2011, the U.S government approved the use of ethanol blends up to 15% for use in motor vehicle models manufactured after 2011. Ethanol blends of up to 10% have been in use for a long time without any need for modifying the engines. The main question all along has been whether ethanol is sustainable as a biofuel alternative.
2. Biodiesel
Biodiesel is becoming more popular, and it mimics the traditional petroleum-based diesel. Biodiesel is, however, derived from recycled cooking grease, animal fat, vegetable oils. Most biodiesel companies tend to collect used cooking oil from restaurants and convert it into usable biodiesel, which can be blended with the conventional petroleum diesel. Some military vehicles, trucks, and buses in the United States use fuel blends composed of up to 20% biodiesel as pure biodiesel may be compromised by frigid weather, causing complications in older engines.
3. Biobutanol
Biobutanol is the lesser-known fuel among the three biofuels, but it has the most potential. Biobutanol is isobutanol made from algae or bacteria, instead of animal or vegetable fats like biodiesel. Standard gasoline engines can use Biobutanol without prior engine modification.
