Advantages And Disadvantages Of Biofuels

Thirdly, the cost of biofuel is high because its production and infrastructural cost is humongous. To create biofuel, large tracts of land need to be cleared for setting up the plant. This is not feasible because of global economic meltdown whose one major disadvantage is the rising food prices. If the land that could be better used for producing the much needed food crops, there is no need to use the same land for generating biofuels (FAO 07). Furthermore, the cost of establishing and running a biofuel plant runs into billions. Where would the money come from? Of course, the people have to pay for them, doubly, first for purchasing biofuel and secondly in the form of taxes. Ironically, the common man cannot afford such expenses given the current economic situation, which if not controlled will create more problems in the future like unemployment, an issue more important than debating biofuels and diesel fuels (Stern 07).

Anything containing oil has been an increasing problem to the environment and to people. The toxicants that the oil produce harms people with their health. In the film Fuel, the director Josh Tickell talks about how crops can produce fuel, which produces cleaner air and is safer for the public. There are also other ways that Biofuel could be produced, such as adding human waste onto algae. The way that society utilizes oil is hurting the world, which in fact is affecting the human population and environment, but people only realize it until it is too late. With biofuel people would not be in danger and it could be produced without struggling to find oil.

The current technology in it’s infant stage isn’t capable of clearing the blockage to clean sustainable energy. According to a study by University of California, it is estimated that it will take 131 years to replace gasoline and diesel fuel which leave 90 years energy gap between end of conventional oil and alternative energy. Even if we start aggressively replacing biofuel, it will take much longer than the expected 30 to 40 years of known oil left so it is reasonable to conclude that it’s unlikely we will stop drilling and mining for oil even with all its known environmental and health risks. We can’t stop drilling but we can try to minimize the cost to our environment and our health through technological innovations but it will required great pressure from the people. We can’t rely economic forces to drive for innovation in energy because economic forces don’t account for 20 or 30 years ahead or any environmental factors; it simply cares only for short term profits. As long as oil remains relatively low, it will be business as usual because unless alternative energy can competitive in the market, it’s advancement and breakthrough will not occur. Biofuel have the potential to replace some of our fuel needs but replacing fields for fuel crops is challenge to our food supplies especially the future food crisis is an equally challenging problem in itself.

Some of the disadvantages are that it's very expensive, its difficult to store and transport, and its flammable and its impossible to detect leaks. However, biofuels have none of these problems.

Initial research has shown that biodiesel, liter for liter, generates about 90 percent of the heat of traditional fossil fuels, and the resulting air emissions are significantly lower in sulphur, carbon monoxide, and hydrocarbons. Burning these fuels also does not contribute to global warming. Fossil fuels increase the amount of carbon in the atmosphere because the carbon they release upon combustion has been locked away for millennia. The carbon released by the combustion of biodiesel first had to be removed from the atmosphere by the plant that produced the oils it was derived from. Thus, no net gain occurs when said carbon is released. Biodiesel is also safer for people and the environment since it is non-toxic and biodegradable. Oil spills will no longer be multi-million dollar environmental catastrophes.

Biofuels are biologically derived fuels obtained in a renewable way from organic waste. These organic remains usually come from sugar, wheat, corn or oilseeds. They all reduce the total volume of CO2 emitted into the atmosphere as they absorb it as they grow and emit virtually the same amount as conventional fuels when they burn, resulting in a closed cycle process. Biofuels are often mixed with other fuels in small proportions, 5 or 10%, providing a useful but limited reduction of greenhouse gases. In Europe and the United States, legislation has been in place requiring suppliers to mix biofuels to certain levels. This legislation has been copied by many other countries that believe that these fuels will help to improve the planet through the reduction of gases that produce the so-called 'Greenhouse Effect '.

To solve the rigorous threat to earth from global warming, bio-fuels serve as the most feasible source of energy all over the world. The environmental and economical performance of bio-fuel as compared to fossil fuel was analyzed by full Life Cycle Analyses (LCA) in Spain. The Spanish government CIEMAT, carried out two LCA’s so as to compare ethanol-ethanol mixtures with gasoline, and biodiesel-biodiesel mixtures with fuel oil according to ISO 14040-43 standards, these standards evaluate energy and mass balance for two or more objects. It was concluded that carbon dioxide emission during utilization of bio-fuel are lower than fossil fuel and bio-fuel requires less primary energy to be processed than fossil fuels. Bob Dinneen, President and CEO of the Renewable Fuels Association submitted the letter to the editor of The Gazette in which he marked that “On an environmental level, conventional ethanol is reducing greenhouse gas emissions by 34% compared to petroleum, including hypothetical land use change emissions” (qtd. in renewable fuel association). As the raw material for

For over forty years now, scientists and researchers have been tirelessly searching for an alternative to fossil fuels. Biofuels have become an interesting contender in the search for the replacement of the non-renewable energy source. Biofuels have been used throughout history for over thousands of years. There is a large debate over biofuels and its true impact on the environment. Those involved in the discussion debating whether biofuels have any real overwhelming benefits compared to fossil fuels could argue for its usage. According to recent research performed by the University of Michigan, biofuels may not be the best alternative for fossil fuels. Regardless of its impact on the environment, biofuels are becoming more popular particularly when the price of oil rises.

In the United States biofuel production has grown a lot over the last two decades. In 1995 production was at 500,000 gallons, by 2005 it was 75 million gallons, and by 2006 it was at 224 million gallons [Biofuels ‘13]. The main plant used in the United States biofuel production was the soybean [Biofuels ‘13]. Currently 4 percent of the world’s demand for primary energy comes from biofuels. The more popular and more well-known hydropower only provides 2 percent of the world’s primary energy demand [Maugeri ‘10]. Most modern cars can use up to a 10 percent biofuel mix in their engines without any modifications, though some cars called flex-fuel can use 100 percent biofuel or gasoline [Maugeri ‘10]. One big advantage to using biofuel is that it produces a higher octane rating than gasoline which helps improve engine performance [Maugeri ‘10]. Biofuels currently cost a little more to make compared to gasoline at about a ten to eight ratio respectively [Sanders ‘10]. Hopefully with more farms producing the components for making biofuels hydroponically it can help drive the price down to where it can be competitive with gasoline and one day completely replace it.

However, fossil fuels have important roles in safeguarding the agricultural sector by providing the chemicals required for the production of nourishments for excellent crops fertility, and insecticides for killing parasitic animals which reduce food demands. Thus, this improvement can help reduce hunger around the world, as it provided about 60% of the world’s food consumption (Goklany 2013). As shown below, fossil fuels invest several raw materials that is required for the harvesting of food supply (PB&J

Nowadays, biofuels have become essential for future economic development and environmental protection. Primarily, their environment-friendliness and low carbon emissions are emphasized as the main advantages. However, in reality, few investigations were made to find out the disadvantages of such renewable alternative, and it may bring much more negative impacts than its advantages.

An advantage biofuel has which will benefit the society is it’s cost benefit. The current cost of biofuel is approximately the same amount for gasoline, however the overall benefits of using biofuel is much higher. Biofuels are cleaner fuels meaning that they produce fewer emissions when burning. The biofuel industry is expected to fuel economic development in poor rural countries, allowing these 3rd world countries to develop with more economic stability as it also creates room for employment. Also, biofuel will also increase the demand for suitable biofuel crops, which enables economic stimulation in the agriculture industry particularly in rural countries.

Carbon dioxide, the chief byproduct of fossil fuel combustion, is a potent greenhouse gas that remains in the atmosphere indefinitely. In the U.S., the burning of coal for electricity pumps more than 2.4 billion metric tons of carbon dioxide into the atmosphere every year, according to the Energy Information Administration. People ask what about the cars? How do they affect the environment? The average American passenger car spits out 11,450 pounds of carbon dioxide every year. There are 246 million cars in the U.S. To cut down on carbon dioxide emissions, governments, car manufacturers and utility companies have been seriously pursuing alternative energy sources. Among the leading contenders are biofuels - renewable, clean-burning fuels made from plant- and animal-based source materials like corn, soybeans, discarded vegetable oil or animal fat. We hear a lot about biofuels and fossil fuels in the news, but sometimes the two terms can get tangled in our minds. Are fossil fuels really made from fossils? Can a regular car fill up on biofuels? Are there any clean-burning fossil fuels, like natural gas?.

In the world of global warming, all kinds of pollution and fuel shortages going on, renewable and clean/ green energy is increasingly the ideal solution of energy related problems we have to solve one way or another. Biofuel is one of the mainstream and highly supported solutions nowadays, an idea to make renewable fuel by living organisms such as fiber, corn, vegetable oil or sugar cane. Unlike nonrenewable fossil fuels over extracted by people causing various environmental problems like generating a considerable amount greenhouse gas, current technology already lets renewable fuel like biofuels to shrink a certain amount of greenhouse gas production, making it a more ‘clean’ source of energy.

Many including Rothkopf, Grunwalf, and Ruiz-Marrero claim that biofuel is not the solution but rather will become a problem. They claim that if biofuel was produced in large quantity then agriculture would convert from food to fuel. According to the World Bank, over seventy five percent of the rises in food prices is directly caused by biofuel. Indonesia is the leading producer of palm oil, a major biofuel. In order to increase productivity, the people destroyed thousands of trees to plant palm tree. The destruction led to an increase in carbon production. Indonesia moved from the 21st most carbon producer to the third. Another major producer of biofuel is Brazil. If Brazilian farmers were to deforest the Amazon rainforest, it could cause a fifty percent increase in global warming. Through the world, deforestation accounts for over twenty percent of carbon emission. A gallon of biofuel requires the same amount of grain as a person would eat in a year. The switch from food to fuel would cause a worldwide food shortage and an increase in world hunger.
