Over the past years, planet Earth has been warming up. According to NASA's Goddard Institute for Space Studies, average temperatures have risen around1.4 degrees Fahrenheit/0.8 degrees Celsius since 1880. In fact, the rate of warming is increasing. It was reported by a number of climate studies that the last two decades were the hottest in 400 years. Global warming is a major threat to the planet. It is agreed that humans have caused most of the past century's warming by releasing greenhouse gasses, as we power our electronic lives. The “greenhouse effect” is performed when the gasses let out into Earth’s atmosphere trap heat from the sun. Through the burning of fossil fuels, humans are enhancing the greenhouse effect and increasing the temperatures of the planet. Although the greenhouse effect is what keeps the planet warm, thereby supporting life, too much would also result in severe issues. Now, with the increasing rate of greenhouse gases emissions, frozen glaciers are melting, sea levels are rising, and wildlife is scrambling to keep up with the fast pace. Above that, weather can also become more and more extreme. Something has to be done.
As stated earlier, the burning of fossil fuels to produce energy is one of the largest contributors to global warming. This non-environmentally friendly energy source has to be replaced in order to keep the world going. There is a type of energy source that seems easy to create and doesn’t require radical changes: Biofuels. Biofuels are a greener version of diesel and oil. They are any solid, liquid, or gas fuels produced from organic matter; the range of organic materials used for biofuel production includes plants such as corn, sugar cane, soy, and wheat; vegetable oils and animal fats; ...

... and soil scientist at the USDA Agricultural Research Service Corn stover has been historically left in the field as cover to reduce soil erosion and for conserving soil nutrient contents. The immediate environmental concern of using corn stover for biofuel production is soil erosion. In addition, when we take a look at the big picture, the 0 carbon emission theory is wrong, as it does not take into account the vast amount of carbon released into the atmosphere from land conversion. Global warming is inevitable. The disadvantages definitely outweigh the advantages.
In conclusion, the fact that biofuel is renewable unlike other natural resources such as coal, nuclear fuels, and petroleum makes it an excellent energy solution. However, there are still several major problems that need to be fixed before biofuel is recognized universally and used on an industrial scale.

In conclusion, Corn Ethanol Biofuel has many negative and positive effects. It has a negative effect because it releases greenhouse gases but positive effects as well because it is inexpensive to produce and use, and is a renewable source. The future of corn ethanol is uncertain: “Corn-based ethanol will most likely not be the staple fuel source in the future, as it is only a short term solution and poses problems in the long run. Ethanol contains 33% less energy than gasoline, and corrodes engines that it is used in. Average production and final sales are 62 cents/gal higher than conventional gasoline. Even though political support is waning, Congress will most likely not abandon corn ethanol.” ("Future of Corn Ethanol.) I think corn ethanol
In the United States we have been looking into alternative energies to reduce our dependence on oil and help reduce our carbon footprint. One method the EPA has come out in support of is ethanol production. Ethanol is considered a green fuel because it recycles the burned carbon each time new crops are grown. In theory ethanol is a good stepping stone between using gasoline and zero emission power sources. However biofuels are still young technology that has many problems before it can be useful. The EPA is in full support of biofuels and has mandated that by 2020, 36 billion gallons of biofuels are to be produced in America. Currently almost all of America biofuels comes in the form of corn based ethanol which is extremely inefficient and can cause sustainability problems. Due to this reason only 15 billion gallons of the mandated biofuels can be form corn based ethanol. The rest of the biofuel must come from non-corn based alternatives such as cellulosic ethanol which the EPA projects to create all most all of the 21 billion remaining gallons of ethanol. Cellulosic ethanol uses the cellulose that is in all plants matter to create ethanol. Cellulosic ethanol is far more efficient than corn ethanol because you can use the whole plant and it sets no limitation on what type of plant matter can be used. Even though the EPA projects that these number will be achievable, due to current setbacks and efficiencies cellulosic ethanol will not be able to meet this output within the time constraints and a goal of 2034 years would be more realistic in the long run.
“All Biofuels Are Not Created Equal” is a very informative article that everyone should be aware of. The authors of this article show how biofuels can be made to benefit Earth. Our ecological footprint is so big that everyone requires 2.5 Earths to maintain the same lifestyle. What does this reveal? It reveals that Earth’s resources are being diminished. This means that the world needs to do something to prevent this so Earth can last for future generations. The way that biofuels are being made is not very effective in helping this problem. This is because it either requires deforestation or the burning of fossil fuels, which the world is trying to stop. Instead of using corn or sugar cane as ethanol, alternative crops should be used because it will benefit our environment the most.
Biofuels, fuels that provide energy using relatively recent organic sources, have been around just as long as cars have. In fact, the first cars ran on peanut oil. Henry Ford, founder of a multimillion dollar American car company, planned to fuel his massively successful Model T’s with ethanol (National Geographic 2013.) However, this revolutionary idea was swept under the rug when the discovery of massive petroleum deposits kept gasoline and diesel cheap and affordable. As 2014 rolls around, consumers are starting see that the amount of petroleum in the Earth is shrinking and the same story goes for their wallets (Avro 2012.) Not only does burning gas and diesel empty out the wallet, it is also slowly covering the Earth with a warm carbon dioxide blanket that causes global warming. Transportation, which is the third largest emitter of greenhouse gasses (Biofuel Association of Australia 2013), is dependent on finite amounts of gas and diesel for its energy needs so it is very important we move towards a more renewable and sustainable fuel source. Biofuels, both ethanol and biodiesel, have the potential to fuel transportation efficiently and drastically reduce the carbon footprint, thus reducing the warm blanket of carbon dioxide on the Earth.
With the ever‐rising prices of fossil fuels and the realization that our supply is severely limited, the need for an alternative energy source is rising steadily. Clearly the most efficient of the alternative options lies in bio fuels because they are naturally grown and thus have an unlimited supply, have virtually zero emissions, and can be us...
Fossil fuel plays leading role in upsetting environmental and climatic protection. Our earth is at catastrophic risk by the exploitation of fossil fuels. Therefore, Pressure is on to find viable alternatives for energy to save bring a clean revolution. In that case, Bio-fuels make an attractive alternative for energy than fossil fuels. Various provocative questions need discussion that what are the attractive differences between both the fuels, why fossil fuel dependence are to be actually minimized? Why Biofuel magnetizes the environmentalists and people as viable substitute to fossil fuels? What is the scope of Bio-fuel for safer world in upcoming years? Above all, It will be conferred that why Biofuel is better than fossil fuels.
“The fuel is produced in a thermal/mechanical processor called a biomass fractionator. In a matter of minutes, the fractionator converts biomass like crop residues, algae, soft wood chips and rapid growth crops like switchgrass into multiple gas streams and into biochar. The gas can be upgraded to gasoline In a one-step catalytic conversion process.” (Rocke 1). The idea of this fuel source is also very cheap. It runs for about $1.50 per gallon. Finally, the use of Biochar can be shipped at in gallon tanks very easily. Aside from the cost and shipping efficiency, ‘According to one prominent study (Woolf et al, 2010), sustainable biochar implementation could offset a maximum of 12% of anthropogenic GHG emissions on an annual basis. Over the course of 100 years, this amounts to a total of roughly 130 petagrams (106 metric tons) of CO2-equivalents. The study assessed the maximum sustainable technical potential utilizing globally available biomass from agriculture and forestry. The study assumed no land clearance or conversion from food to biomass-crops (though some dedicated biomass-crop production on degraded, abandoned agricultural soils was included), no utilization of industrially treated waste biomass, and biomass extraction rates that would not result in soil erosion” (International Biochar Initiative
In reality the fuel used by everyone today is made from corn and could plant corn forever, but eventually it will cause land exhaustion, making it harder to grow any crop at all. Once the land is dried and unable to reproduce anymore food or supply, there will be no more oil production left in the world. This not only increases the process of fuel making, but it also increases the price range, because the modern oil is enriched, and thick, oil like that is hard to reproduce, but it would be easier if the nations switch oil to Low-Carbon fuel, this type of oil helps save more money because it is just taken and recycled like paper plates or plastic water bottles. Also making of this oil is quicker, in terms of reproducing it faster and selling it for quite cheap/low price. The US government has mainly relied on corn for it's biofuel, which in return can only harm and damage the local or other nations environment. Some people might ask, is it the governments fault or is science to be blamed for this lack of knowledge on gaining a low-carbon fuel? Science is not blaming ,because since the government uses corn for almost every single thing, Scientists do not really have the chance to experiment. The society isn't ready to invest in a such high risk of loosing money. Many people think that the reusable fuel is filthy, unclean, and cannot be reused, but what they don't realize is that re-using fuel can not only protect the environment but also decrease the pollution levels that are harming the earth, and if people invest now they'll earn more back, by saving it from gas.
Biodiesel products like ethanol is very ineffective as compared to gasoline and you are always forced to mix it with some little amount of gasoline to make it efficient. It’s also important to note that long term of ethanol is not recommended as it can damage the engine.
Biofuels have been around as long as cars have. At the start of the 20th century, Henry Ford planned to fuel his Model T’s with ethanol, and early diesel engines were shown to run on peanut oil. But discoveries of huge petroleum deposits kept gasoline and diesel cheap for decades, and biofuels were largely forgotten. However, with the recent rise in oil prices, along with
...l production from food crops is not economically viable, thus the biofuel production from lignocellulosic plants is less likely to be. There are uncertainties regarding if the lignocellulosic crops are really going to decrease the water consumption of ethanol production. And finally, biofuel production can cause food insecurity within the producer countries and sometimes it can be expanded to the rest of the world due to the increase of prices.
According to The Fourth Assessment Report of the Intergovernmental Panel on Climate Change, “Temperature records from as far back as 1850 show that the globe has on average warmed by 0.8 degrees celsius, and further analysis has shown that since the 1970s each decade has been warmer.” (IPPC, 2007). It is expected to keep getting warmer according to IPPC and they also are estimating that the average temperature will be 2.5-4.7 degrees celsius higher in 2100. It has also been found that climate change is due to the greenhouse effect which is also produced from human activity. Greenhouse gases in the atmosphere have increased so rapidly since the Industrial Revolution that they are now changing our climate very quickly. High levels are collecting heat that is being reflected from the land and ocean and is making the air and water temperatures warmer because it is preventing it from escaping the Earth’s atmosphere. In order to keep this from happening human activities such as fossil fuel, deforestation and the conversion of land for agricultural use needs to be used
Coal and crude oil are non-renewable resources. They take an extreme amount of time to form and due to that, they cannot be replaced once they have all been used up. However, when it comes to the biofuels, they are produced from plant material and are renewable. There are two types of biofuels: Biodiesel, which is made from rapeseed oil and other plant oils and is used in diesel-powered vehicles without needing any modifications to the engine, and Bioethanol, which is a liquid fuel that burns quite well and is made by fermenting sugars from sugar cane, wheat and other plants. In this essay, whether or not biofuels are becoming an increasingly important alternative to traditional forms of energy under environmental and economic benefits and
More farmers are now planting crops for biofuel, resulting to an intense drop in food production. According to experts this promising alternative energy source is seemingly causing a global decrease of food supply. As the demand for biofuels increases, more industrialized countries are offering encouragements and subsidizing farmers to grow crops for fuel rather than for food. The biofuel production method was also anticipated to be carbon neutral, as the crops would absorb the carbon dioxide released when the biofuel was burned. However crops for fuel are now grown at such a rate that they need more energy to cultivate, grow and harvest. By the time it reaches households, it would have consumed more energy and released more greenhouse causing substances than the feared fossil fuels would have. The fact that emissions are released during production, processing, fertilizer application and as a result of land use change is highly ignored. Somehow biofuels can sidetrack less harmful and clean resources like renewable energies such as solar and wind energy. Large scale cultivation of biofuel crops, unlike small scale, locally produced and biofuel owned farms are commonly challenged by problems such as severe use of water, chemicals, fertilizers and pesticides. These also often lead to pollution, depleting and degrading available water resources which can cause famines. According to contrary believe of analysts, it has also shown that there is not enough farming land on earth to produce biofuel crops to meet the huge energy needs encouraged by our current and unmaintainable ways of living. http://www.greenerideal.com/science/0516-biofuels/ &
