The History of BIOFUEL One of the first inventors to convince people to use a biofuel called ethanol was a German named Nikolaus August Otto. The diesel engine and the Model T were designed to run on Biofuels like peanut oil or one made from hemp respectively. During war times when oil was hard to acquire, Biofuels made their way into England and Germany with alcohol made from potatoes and a mix of grain alcohol with petrol.

Rudolph Diesel, on August 10, 1893, first demonstrated the use of peanut oil to run his compression ignition engine. This date has since come to be known as International Biodiesel Day.

Types of Biofuels Bioalcohols – Mainly ethanol, they can be used to run vehicals but their output of energy is slightly lower. Another use of ethanol is in fireplaces, it can burn without a chimney. Biodiesel – Biodiesel is a mix of oil and diesel. It is compatible with any diesel engine. Green diesel – diesel created from renewable feedstock rather than fossil feedstock. Its uses include the same as ordinary diesel and biodiesel. Vegetable oil – Is processed into biodiesel or cleaned of water and particles for use as a fuel. Mainly used for cars.

Types of Biofuels cont Bioethers – enhances engine performance, reduce engine wear, and reduce toxins that are put into the atmosphere. Solid biofuels – includes wood, sawdust, grass, charcoal, agricultural waste, energy crops, and manure. Can be used for heat and electricity.

Uses of Biofuels We use Biofuels to power cars and industries just like oil. We use vegetable oil in old diesel engines and we also mix vegetable oil with diesel to make biodiesel. We are able to make cars than run on ethanol and sugars as well as other alcohols. Solid biofuels and ethanol can be used to create heat by burning them.

Uses Cont. Solid biofuels can be used to create electricity by boiling water to create steam that moves a turbine creating electricity. Almost all biofuels can be used as fuel for cars and especially diesel engines.

Change throughout history Wood would be burned for heat before people even knew about the existence of Fossil Fuels. Since then, many other functions have been discovered. The Main Function of Biofuels today is for fuel for vehicles.

Energy Cost ● There are 76,000 BTU of energy in a gallon of ethanol compared to 116,090 BTU in a gallon of gasoline. ● Gasoline is cheaper per mile, but ethanol is better for the environment. ● The cost effectiveness of biofuels depends on what’s being used to create the biofuel. However, biofuel is actually somewhat expensive when the costs of transportation and production are considered. ● There isn’t really a cost of maintenance as biofuels, unlike other alternative resources, are done after one use.

Efficiency Ethanol, as stated earlier, is not as efficient as its gasoline counterpart. However biodiesel and diesel are very similar to each other. Just a Reminder 76,000 BTU/Gallon = Ethanol 116,000 BTU/Gallon = Gasoline

Efficiency Cont. Biofuels come from organic matter. Is recycled, since it comes from animal waste and plants (dead and alive). Can be used as oil using conversion. Providing heat o It provides more heat in a room than other methods o can conserve more, since a small amount can burn longer than most methods. Disadvantages o it will cause massive deforestation o it will raise food prices (corn and soy prices)

Positive effects Has low carbon emissions into the atmosphere. It is cheaper to produce and convert. Can convert home waste into energy. Doesn't require a radical change to convert. helps prevent engine knocking. Carbon Dioxide released is equal to the amount plants intake, making it much better for the environment than other methods.

Negative effects Increasing food prices! Will lead to a depletion in food supply and increase prices. More habitats lost and a decrease in biodiversity. May cause huge environmental issues and will not be sustainable. Will not be affordable to do. Carbon emissions emitted to the atmosphere.

Future Of Biofuel can be stored as a solid biomass. recovery energy is equal to present day energy consumption amount. questionable amount of energy can be provided at rate of depletion. Is renewable, but depends on environment conditions. Estimated that in 2030, biofuel crops can produce about 100,000 MW of electricity. total provide for whole country would take 50 million acres of 128 million that would available in 2030.

Reason for future use Biofuels should be used because the most natural. It can run an automobile and can be used as a massive heat source. It can use Organic house waste (recycle). doesn't produce CO2 into the atmosphere. In the case of combustion, it is less harmless than other gases.
