Even though biofuels are promoted to use widely by the government due to their economic advantages, they are not able to alleviate global warming because in fact biofuels make the emissions increase. It is said that biofuels can reduce global warming significantly as biofuels burning to transportation contain up to 60 per cent less carbon than the emissions from fossil fuels. Nevertheless, John Duggan (2008, para 1) points out that these studies do not consider the emissions in various stages of biofuel production. Thus, relying on biofuels usage to reduce greenhouse gases emissions may lead to increasing in carbon emissions. According to Greenfield (2006, para 3) biofuels do not add carbon into the air because carbon emitted can be reabsorbed by biofuel crops. However, a study by the University of Minnesota show that “....” (Duggan 2008, para 2). Therefore, biofuels cannot be used to solve climate change.
Not only having some limitations but also biofuels can cause some other serious env issues to the atmosphere so biofuels are unlikely to alleviate global warming. By bringing numerous economic benefits for the governments, they promote biofuels crops and this leads to an increasing of land consumption, which contributes to deforestation

Throughout the past few decades sources of renewable energy have been widely discussed due to the harmful impacts fossil fuels have on the environment combined with fluctuating petroleum prices and our growing demand for an ever depleting resource (Fletcher et al. 2011). Over the coming decades it is predicted that there will be an increase in the use of bioenergy systems (McBride et al. 2011). Bioenergy is commonly believed by both policy makers and environmentalists to be one of the…

Over the last century global temperatures have increased rapidly, and this period has been called global warming. However many have disputed how this rapid increase in the change in the temperature have been brought about. There is a general agreement among scientists that the changes in the climate over the last century are as a result of human activities. They have reached this consensus as they have been able to link the sudden change in rate of the temperature increase to the development of industrial activities beginning with the industrial revolution. The industrial activities that our modern civilisation depends upon have raised atmospheric carbon dioxide levels causing a rise in the amount of greenhouse gases that insulate the Earth. These extra emissions of greenhouse gases have led to a thicker layer of greenhouse gases present in the Earth’s atmosphere. The main causes of this rise in greenhouse gas emission are fossil fuels. The burning of these fossil fuels has allowed us to develop, both economically and technologically, which in turn has enabled us to advance as a civilisation. However the use of these fossil fuels has…

Why do we do this? Because our policy makers have come to believe that the air-born plant food carbon dioxide is a “pollutant” (3) that must be reduced or severe damage will be done to the biosphere. Acting on this belief the US government is planning on turning enough food into fuel by 2022 that could feed half the population of the United States! Even if carbon dioxide were a “pollutant” the use of biofuels produces little or no net reduction in carbon emissions since by some estimates it takes more energy to produce a gallon of ethanol than what one gets back from it when it is burned. "Adding up the energy costs of corn production and its conversion to ethanol, 131,000 BTUs are needed to make 1 gallon of ethanol. One gallon of ethanol has an energy value of only 77,000 BTU." (4)…

First of all, the author asserts that the ethanol fuel would not assist to fix global warming problem. Conversely, the lecturer brings up the idea that augmented of ethanol fuel does not adversely affect the environment. In other words, cultivating plants to produce ethanol fuel not only would not ascend the greenhouse gases but also simply compensate disadvantages of burning such gasoline fuel effects on the atmosphere.…

Energy demand is increasing day by day owing to our dependency upon fossil fuels, which is a limited energy source and also poses negative effect on environment due to CO2 removal. Concerns about increased global energy demand, finite natural resources and environmental issues, are thus intensifying the search for sustainable, clean, renewable and eco-friendly alternatives to fossil fuels (Venkata mohan et al., 2008). Renewable energy can be defined as energy that comes from constantly replenished resources such as sunlight, rain, wind, hydropower and fuel cells. Renewable bioenergy is considered one of the new ways to resolve the current global warming problem. Renewable energy generation and waste disposal are two key challenges…

Fossil fuels comprise 80 percent of current global primary energy demand, and the energy system is the source of approximately two thirds of global carbon dioxide emissions as of 2015 (Foster and Elzinga). For decades, people have argued about whether fossil fuels are helpful to the planet and sustainability. Although, there is no right or wrong answer because renewable and non-renewable resources have disadvantages and advantages. There are very many different variables to be considered in this argumentation. Fossil fuels make up most of Earth’s energy.…

Humans are creatures of greed. They take, they eat, they consume, and they use with abandon. On a subconscious level people have become accustomed to ignoring the consequences of their actions because “that is just how the system works.” When it comes to the business of energy and energy consumption, they find themselves in a situation that is more than similar. We as a race use fossil fuels daily, with at least some knowledge on its affects on the environment, and we scarcely bat an eyelash. “How else can I get around?” or “How else can cities be powered?” are common questions when confronted with the idea of living without fossil fuels, as if there is no other way. “Earth provides enough to satisfy every man’s need, but not any man’s greed” (Mohandas Gandhi). We have begun to trek down a dangerous path where we cannot help but rob the earth of its resources and riches without giving back. And despite the fact that there are ways to easily power this world without the assistance of these ancient carbon remains, it is not a viable option; this is because this requires much effort in the realm of change, and changing “the system” would be too costly. Before we can think of a way we can reverse this process and use this excess carbon dioxide to our advantage, people must stop it in its tracks. The human race must adopt biofuels, mainly because they neither contribute to nor take from the problem. Fuels made from Biomass will only release as much carbon dioxide as they absorb, to grow, upon combustion. If people continue on this path we will soon reach carbon-atmosphere levels equivalent to that of when dinosaurs roamed this earth; consequently, we need to stop immediately.…

The sky is falling, the sky is falling! Growing up I heard this phrase in folktales as a “wolf cry”-- a cry that is so ridiculous that nobody would believe it. Now that global warming is a major environmental issue, the saying doesn’t sound so out of place. Most people might say: what is global warming? That’s the question that was running through my mind when I first heard we were watching a documentary on it in my English 130 class. The film is Al Gore’s An Inconvenient Truth and it is about the causes of global warming and what it is doing to our planet. Being an environmentally involved citizen and growing up with conservative Republicans as parents, I was torn between not really liking Gore and this extreme reality that I felt was an impending doom on Mother Earth. The day before my writing class my dad called me and I brought up the fact that I was watching Gore’s film; his reaction was, “I’m paying for you to do that?” I tried to tell him it wasn’t about Gore and when I brought up global warming he claimed it was a scheme to get money and that our wor...…

Petroleum has been a mainstay of the United State's economy for almost a century. However, oil has now been recognized as a strong catalyst for global warming, it is becoming scarce and therefore, an expensive necessity to America's economy. In the recent years many universities and scientists have looked for alternatives to oil in the form of renewable energies. These renewable energy sources would be cheaper in the long run, more efficient and environmentally clean. America as a whole must look into these new forms of renewable energy to determine if they are a practical alternative to the use of petroleum as an energy source. If we do not try to find a clean and efficient alternative to fossil fuels, I am concerned for the future of our world.…

Biofuel is a type of fuel which has energy that is derived from biological carbon fixation and include fuels which are generated from biomass conversion, such as liquid fuels, solid biomass, and various biogases. Biofuel can decrease fuel costs and reduce the CO2 emissions (Jason Hill 2006). Biofuel can be produced by using some of the crops especially corn. The demand of biofuel is increased which is because of biofuel is used as an alternative source of fuel. This is because of the fuel supplies are depleted caused by worse climate. Therefore, when the demand of biofuels increase, it also soared the price of food, especially corn.…
