Transcript: Biofuel hello class today we will be learning about biofuels. biofuel is a resource that we can get from waste cooking oils, and animal fat its also not toxic. enoy!!! =) Disadvantages There are many disadvantages to bio-fuel like it requires more energy from the fossil fuel to produce. When growing bio-fuel it will reduces farmlands that will increase the price of food which is important for human life. Certain weathers can damage bio-fuel like when a tornado hits, it will destroy the plants that means no more bio-fuel for a long time. Also it cost lots of money to grow the plants since they need lots of fertilizer, seeds and all the other things to required to grow plants. Advantages There is lots of advantages using bio-fuel like its renewable since they can grow the plants every season. It can be made from plants or animals fat and vegetable oil. It is much more better for the environment then fossil fuels. It doesn't contribute to global warming since bio-fuel only releases the carbon dioxide that is absorbed while growing unlike fossil fuel. Unlike solar or wind energy it is easy to switch over to bio-fuel because you don't need to buy special tools(such as installing solar panels) for the use of bio-fuel. Also vegetables wastes from restaurants can be turned into bio-fuel to run vehicles to deliver the supplies. For example McDonalds in the United Kingdom has turn their vegetable oil into bio-diesel to run their fleet trucks. Bio-fuel is enviromentally friendly, easy to use and renewable. Since bio-fuel have much more advantages then fossil fuels we should be using it more often. We have to switch to bio-fuel because once we run out of fossil fuel we are not getting anymore fossil fuel so we need more alternative ways to make energy for the whole world to use. Bio-fuel is a way to solve the energy crisis.


Transcript: Bio fuels have been around since man created fire. Wood is the first type of bio fuel used by people; we used it for cooking and eating. When people discovered electricity they used biofuels before people discovered fossil fuels. When they discovered fossil fuels they realized that it went further and it was cheaper. When Henry Ford designed the model T it ran on hemp derived bio fuel as fuel. But when large supplies of crude oil and petroleum were in the country fewer people were using bio fuels. Bio fuels have been used for many years. Bio fuels are coming back from not being used at all to bio fuels being used for gas around the world. But now Brazil is the biggest ethanol users in the world. Evan Morgan Scientists are taking steps to measure each biofuels actual lifetime emissions to help determine which may have a positive impact on the environment. Also scientists are questioning that biofuel can help slow down global warming. If it does the real cost would be low, but when it does not work the real cost will be high and we will be forced to find a new solution and see if that works. Corn based ethanol’s real price can be a lot of money because they have to pay the farmers to grow the corn. They also have to export it to another place. Since lots of biofuel come from Brazil we have to get it imported here. Brooks Poirier Biofuels in the solid form has been in use ever since man discovered fire. Wood was the first form of biofuel that was used even by the ancient people for cooking and heating. With the discovery of electricity, man discovered another way of utilizing the biofuel. Biofuel had been used since a very long time for the production of electricity. This form of fuel was discovered even before the discovery of the fossil fuels, but with the exploration of the fossil fuel like gas, coal, and oil the production and use of biofuel suffered a severe impact. With the advantages placed by the fossil fuels they gained a lot of popularity especially in the developed countries. Liquid biofuel have been used in the automotive industry since its inception. In the period of World War II, the high demand of biofuels was due to the increased use as an alternative for imported fuel. In this period, Germany was one of the countries that underwent a serious shortage of fuel. It was during this period that various other inventions took place like the use of gasoline along with alcohol that was derived from potatoes. Britain was the second country which came up with the concept of grain alcohol mixed with petrol. The wars frames were the periods when the various major technological changes took place but, during the period of peace, cheap oil from the gulf countries as well as the Middle East again eased off the pressure. One of the first inventors to convince the people of the use of ethanol was a German named Nikolaus August Otto. Rudolf Diesel is the German inventor of the diesel engine. He designed his diesel engine to run in peanut oil and later Henry Ford designed the Model T car which was produced from 1903 to 1926. This car was completely designed to use hemp derived biofuel as fuel. However, with the exploration of huge supplies of crude oil some of the parts of Texas and Pennsylvania petroleum became very cheap and thus lead to the reduction of the use of biofuels. Most of the vehicles like trucks and cars began using this form of fuel which was much cheaper and efficient. With the increased supply the geopolitical and economic interest in biofuel faded away. A serious fuel crisis again hit the various countries during the period of 1973 and 1979, because of the geopolitical conflict. Thus (OPEC), organization of the petroleum Exporting countries made a heavy cut in exports especially to the non OPEC nations. The constant shortage of fuel attracted the attention of the various academics and governments to the issues of energy crisis and the use of biofuels. The twentieth century came with the attention of the people towards the use of biofuels. Some of the main reasons for the people shifting their interest to biofuels were the rising prices of oil, emission of the greenhouse gases and interest like rural development North Carolina buys 5.6 billion gallons of liquid fuels every year. Almost all of this massive volume is imported and adds no value to the state's agriculture, forestry, or manufacturing economy. North Carolina's goal is to produce about 560-600 million gallons of biofuels a year (MGY) from local, renewable resources by 2017. To sustainably replace 10% of the state's petroleum imports will require millions of tons of biomass from cellulosic sources such as energy grasses and wood, providing new opportunities and income to farmers and land owners. Filling up with locally grown and manufactured biofuels blends will allow citizens to empower not just their vehicles, but also the North Carolina economy. Brazil is the biggest country we get most of our of the bio fuel from Brazil Here in the


Transcript: BIOFUEL Biogas Biodiesel Bioethanol Many diesel engines are able to use %100 biofuel hassle free. Others may be better off with a blend of biodiesel and standard diesel Vehicles with certain kinds of engines may require biodiesel conversion kits in order to function efficiently. (varies between $1000-$2000) These kits are also necessary for driving in especially cold conditions. Many newer diesel vehicles warranties will become void with the use of biofuel,due to newer vehicles using engines with higher pressure engines which can cause problems. Due to some areas not having consistent biofuel suppliers, some people have made their own biofuel conversion tanks, using vegetable grease from restaurants. (transesterfication) 1900's Leader in ethanol production In 2007 Brazil produced 32% of the worlds ethanol. US is a large importer - 1.7 million tons in 2006 2/3 from Brazil 1979 dedicated ethanol vehicles -“Did you know? The less oil the United States imports, the less we have to worry about the stability of the countries that supplies that oil. The production of nearly 6.8 billion gallons of ethanol means that the U.S. needed to import 228.8 million fewer barrels of oil in 2007 to manufacture gasoline, or roughly the equivalent of five percent of total U.S. crude oil imports. By choosing ethanol, you can make a difference for our economy.” Biofuel Energy Corp Pioneer Trail, in Wood River, Nebraska. Buffalo Lake, in Fairmont, Minnesota -has 2 plants in USA. Both use existing Cargill facilities. -115 Million gallons per year Wartsila Liquid Biofuel Plants Finnish company active in over 70 countries -uses oil palm, rapeseed, soy, sunflower and jatropha -oils or fats from fish, poultry, and rendering processes – byproducts of food industry that would be waste – also used -Wärtsilä uses straight vegetable oils. No energy consumption for refinement needed.
