Does Biodiesel A Good Replacement For Fossil Fuels?

Is biofuel a good replacement for fossil fuels?

Fossil fuels are a fuel made from plant and animal matter that have been compressed over millions of years. These fuels consist of coal, oil and gas and when burnt to create energy, they produce gases that damage our atmosphere. To cut down on these gases other types of fuels have to be used one of these replacements for fossil fuels is biofuel.
Coal has to be crushed then burnt whereas oil and gas can be directly burnt.
The process of burning fossil fuels for energy is; Fuel is burnt to heat water into steam which is then used to turn turbines to then turn generators which produces electricity.

Biofuel
The process of burning biofuel is the same as fossil fuels apart from the fuel is a …show more content…

Biodiesel is used by itself but bioethanol has to be mixed with petrol to be used. Biodiesel can be used in most diesel engines, and also emits less hydro1carbons than petroleum diesel. It is also as efficient as petroleum diesel. Biodiesel is made of plant oils and animal fats such as canola oil and used cooking oil and even things such as algae. Some of these things are not that useful and making them into fuels gives them a use which cuts our production of greenhouse gases.

Biodiesel is a hydrocarbon with 17 carbon atoms which includes an ester group at the end of the chain. This hydrocarbon is the end product of an interaction of triglyceride and methanol. The interaction between the two leaves fatty acid esters at the end of a hydrocarbon chain, which is the biodiesel, and glycerine which can be used in food processing. The ester group is the difference between petrodiesel and biodiesel. Using bio diesel reduces the amount of sulfur emissions but increases the amount of nitric oxide …show more content…

Another advantage of using a biofuel is that the plants used to make the fuel take in some of the carbon dioxide produced when burning the fuel reducing the amount of carbon dioxide that ends up in the atmosphere. Biodiesel can also be blended with other fuels such as petrodiesel, this reduces the gas emissions of the fuel but also keeps its energy output high. Biodiesel has better lubricity then petrodiesel, meaning it prevents wear on parts such as the fuel injector. There is more oxygen in biodiesel which makes it easier to burn. Also this means less carbon monoxide is produced but, this means more carbon dioxide is produced because of the extra oxygen. This amount is still less than the amount produced when petrodiesel is burnt.

There is also a disadvantage to this though. The fuels are made from plants and these plants have to be grown, replacing areas of which are used for growing food for us. A disadvantage of using a biodiesel blend is that the more biofuel in the blend the less energy that can be produced. Biodiesel has a higher freezing temperature then petrodiesel meaning it is not a very good choice of fuel in colder climates or

The advancement product will not only advance the automobile industry but also improve the conditions of the environment as a whole. The Gas Replacer is a transition package that allows a gasoline-powered engine to transition to operate on biofuels. Biofuels are a renewable energy source derived from living matter, like plants and crops. Biofuels are naturally replenished and supplied so they are continuously available and provide an ecologically better alternative to traditional gasoline.

Ethanol Mandate's Effect On The Beef Industry

987 Words | 4 Pages

Ethanol is a type of biofuel produced from organic matter such as corn, sugarcane, wheat, sorghum, and other grains. The exact feeds that are used to help finish cattle and bring beef from the pasture to your plates. Ethanol is then placed in gasoline as an additive, equaling about a 10 percent Ethanol to 90 percent gasoline ratio. Ethanol not only burns cleaner than gasoline, but also supports the energy Independence Act since we do not have to rely on other countries to supply the corn. The connection between Ethanol production and beef began here in 2007.

Alberta's Economic Benefits Of Changing Over To Ethanol Fuel

788 Words | 4 Pages

Looking at the difference of ethanol fuel and gasoline, the benefits of ethanol fuel by far outweigh gasoline. With ethanol fuel being made from biomass the amount of greenhouse gas emissions is greatly reduced from those of gasoline emissions. This is allowed to happen because when ethanol fuel is burned, it is burned in almost complete combustion making the emissions much more clear and less harmful to the environment. With a reduction of greenhouse gas emissions the benefits to the environment are huge. Our economy would be allowed to spend less money on environmental factors and more for the people.

Pros And Cons Of Corn To Replace Fossil Fuels

538 Words | 3 Pages

One pro of ethanol it that it is sustainable; we can be nearly certain that the corn will continue to grow back and we will have a continued energy source. Another pro is that ethanol releases less greenhouse gas into the atmosphere as compared to fossil fuels (Hill et al., 2006). The cons of ethanol as compared to fossil fuels are also to be considered. As previously stated it could cause a food shortage that would affect a great number of the world’s population. Another con is that ethanol has a lower net energy yield as compared to fossil fuels; that is, by the time the corn is grown and converted to fuel, so much energy has been used in the process that only 25 percent is gained back (Hill et al.,

The Diesel Engine: The History Of The Compression Engine

The reason that fuel also has made the diesel engine and the diesel production better is because there has been so many things that the world has invented to make less fuel miles and also can make you go through more fuel or less fuel. Diesel fuel is a bi produced of gas. The primary use of diesel fuel is in diesel engines. The invention of the diesel engine is credited to Rudolph Diesel, who filed the first diesel engine patent in 1892. His use of peanut oil (rather than a petroleum product) to fuel an engine--demonstrated at the 1889

This is helpful for when you need to be fuel efficient and if it is a vehicles engine, it helps for when you are going to need for the machines engine to burn diesel very slowly, while getting the job done. Many farmers, or any business owners or workers who are away working for long periods of time, would most rather have a diesel engine vehicle rather than a regular gasoline engine. This is because they know that diesel engines are reliable, and last longer on fuel. Most people, who drive diesel trucks, will argue that they are many times better than gas trucks. There is a big percentage of people who purchase diesel trucks, and after that, they never turn to purchase a gas truck ever again.

How Should Biofuels Be Banned In The United States?

On another note biofuels require a large amount of energy to produce and makes it seem like an endless cycle of wasting energy. Evidence of this is that in order to get one gallon of gasoline in terms of energy output, it would require 1 ½ gallons of ethanol a type of biofuel (James and Powell). This means that ethanol is not as efficient as gasoline. This would cause a large amount of waste because more needs to be grown in order to supply the united states fuel supply. Therefore in order to reduce waste, biofuels should be banned in the United States.

Fossil Fuels Pros And Cons

1281 Words | 6 Pages

Although there are a number of proven benefits of substituting fossil fuels with biofuels, no fuel sources are entirely positive or negative. Pros: ❀ Renewable - Fossil fuels are considered non-renewable as they take millions of years to form and the reserves are depleting quicker than new reserves are being formed. This is not the case for biofuels as they can be constantly restored, since they can be produced from biomass which can be cultivated and harvested during the human lifespan. ❀ Economic Security - Large reserves of crude oil do not appear in every country, and so biofuels provide an opportunity for countries to enhance economic security by reducing their expenditures and dependence on oil imports.

Politics- Perspective 2: Renewable energy should not replace fossil fuels because of its many benefits. Environment- When fossil fuels (Oil, Coal etc.) burn, they release many pollutants into the atmosphere and they also release carbon which mixes with oxygen to make carbon dioxide (CO2). The only thing that CO2 is good for is plants in general, because plants absorb CO2 in the day to produce oxygen.
