Introduction : Biofuels, extracts of cereals or other foods, are experiencing a growing interest including as a substitute for fossil energy. However, the use of edible products for biofuel production has recently been classified as a crime against humanity, as it contributes to rising food prices on the world market and the intensification of the phenomenon of famine because all family with weak pension will have difficult to access for all of this food. Biofuels, fuels from renewable energy enjoying growing global interest in recent decades, including as a substitute for fossil energy that represents an unstable market, its impact on the environment, and that it is an energy that is not sustainable. Biofuel are asking in the world market come from all kinds of sugars, mainly maize, sugar cane, sweet potato, sorghum (for manufactures Ethanol). eg biodiesel, which is produced mainly in Germany and France, it comes from the transesterification induced by ethanol or methanol, oils extracted from rapeseed, sunflower, soybean or palm oil.
In this few years ago, with the UN targets for reducing greenhouse gas emissions, many countries have adopted different objective for replacement of fossil fuels with biofuels; in Europe, 5.75% of the energy

Of these, growth demographics, increasing demand for energy combined with the decline of fossil fuels and increasing demand for meat products in developing countries as a result of the evolution of societies. In addition to the factors mentioned above, the supply and demand have recently influenced by different international policies that attempt to achieve sustainable development goals and gas emission reduction of greenhouse gases through the production and integration of biofuels on their territory. For example, biofuel production targets in Europe 2015 are about 130 billion gallons and the United States for 2022 is almost 140 billion
As an emergency response coordinator for a refinery it is vital to understand what hazards are associated with the products found in a crude oil refinery. Routine and non-routine maintenance will need to be done in order to maintain a working and operating oil refinery. This can create complicated situations or scenarios, because numerous contractors may be brought in for different repairs. This can lead to accidents in some cases because of the wide range of things going on in the refinery. Training and communication will be vital for a safe work environment with multiple entities working. Documentation of the training will also be crucial.
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; ...
Our energy needs have significantly changed since the first Industrial Revolution that took place in the period from about 1760 to sometime between 1820 and 1840. Before this time period, our energy needs were modest. For heat, people relied on the energy of the sun, but when it failed them, they burned wood, straw and dried dung. For transportation horses and the power of the wind was used in sails. For agricultural work animals were used to do the jobs that could not be done with man labor. By harnessing the power of steam and wind simple machines could be run to grind our grain and pump our water. The Second Industrial Revolution, also called the Technological Revolution is considered to have begun around the time of the introduction of the Bessemer steel in the 1860s. This technological Revolution is considered as the second phase of the Industrial Revolution that resulted in factory electrification, mass production, the creation of production lines and the development of machine tools. With the appearance of the low cost automobile and the wide spread of electricity our society's energy needs have changed forever. Since the modest beginning of the oil industry in the mid 19th century, petroleum has risen to global dominance leading to mass consumption as the primary fuel to generate electricity, heat, to power our homes, cars and to support economic growth. Unfortunately, as a consequence of industrialization, atmospheric CO2 levels started to rise in proportion to the usage of fossil fuels. This trend raises some concerns about the well being of our environment, and researchers around the world started to look for alternative, cle...
“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.
Introduction:The idea of biofuels is a old concept, reaching as far as the ending of the 19th century. Solid in its idea but flawed in its presentation. Biofuels are a alternative energy to fossil fuels that are made from natural methods such as plants and crops and are key in solving the apparent flaws of fossil fuels. While fossil fuels have been in use for over a century, Biofuels have now risen to the popularity and been exposed to the press. At one point of time biofuel were being considered by some of the most brilliant minds ever in human history such as Henry Ford and Rudolph Diesel who believed that biofuels had the potential to be the new evolution s on only to reappear a century later. Now the world faces the struggles of global warming and the depletion of fossil fuels slowly dimming by day. Throughout the last century biofuels have proven to have a place in our society as a new alternative fuel source. Specializing in Being Natural and healthier than fossil fuels, biofuels have had a rough beginning against its competitor due to key situations such as pricing, Side effects, to fuel power. However the idea was passed on a to the later generations, and continued to pasand prolong usage. However through the last decade they have been highly advertised by politicians and Government officials claiming it to be the future of a powerful working society, and to help in making a new energy free world. Through belief Some even claiming that “By 2050, a new generation of sustainable biofuels could provide over a quarter of the world’s total transport fuel, according to a recent report by the International Energy Agency” (last name). With such improvement biofuels should be the obvious answer to providing a better future to th...
From the home to factories, families and industries are reliant on the use of nonrenewable fossil fuels to feed the needs of the everyday human. Fossil fuels are the main source of energy over clean, renewable sources such as the use of wind, solar energy, and water to power our homes, schools, and industries. In fact, about 85% of energy use comes from fossils fuels. The main reason being that using fossil fuels is cheaper than wind and solar energy. “For nearly two centuries, fossil fuels have been the cheapest source of energy” and widely abundant (Marburger, A global framework: international aspects of climate change). However, overtime fossil fuels will disappear due to the lack of time to replenish itself with the human races rapid use of it. Despite its current status of availability, there are many controversial issue in using fossil fuels; the most prominent issue being that it is the cause of rapid climate

Technically, the method is not thought of as a biofuel because it was not produced from a crop. Ethylene is used and it is produced through catalytic cracking. This is an addition reaction that is exothermic and is shown through the equation: CH2=CH2(g) + H2O(g) → CH3CH2OH(l) ΔH = - 45kj
As a result, the parliament agreed to the climate change bill in 2008, which aims to emissions reductions (Giddens, 2008). One of the UK government targets is to reduce the carbon dioxide emissions by at least 60% by 2050 compared with 1990 level, and 26% to 30% by 2020 ibid. Furthermore, the government has an obligation with EU to achieve 15% of its energy including electricity, transport fuels and heating, to be from renewable sources by 2020
As the world population grows and consumption per person increases, the demand for food is rising. To an extent, fossil fuels have made an increase in food production achievable, but the finite supply is rapidly depleting. Over the last 50 years, global food production has tripled (Mosier et al. 2004). Despite this, an estimated 870 million people were undernourished in 2010-2012 (FAO 2013) while in 2008, 5...
Both biodiesel and ethanol are derivatives of biomass that have been processed to create a liquid biofuel. Both types of biofuels have been touted as secure and environmentally safe alternatives to fossil fuels, however the research verifying these claims is extensive but often contradicting. In the following paper, the efficiency and quality of the two types of biofuel will be discussed. The effects of variables such as source materials and production techniques on efficiency and quality will be considered. Due to the limited scope of this paper however, only generalized net analyses of ethanol and biodiesel production will be considered. The production of ethanol requires one of two source materials, cellulose or sucrose, both of which are complex sugars. Currently, corn and sugar cane are the primary source materials for ethanol; however it can be produced from any plant cellulose. Ethanol is created using chemical and non chemical processes. These processes include liquefication, saccharification, fermentation, and distillation (Malca and Freire, 2006).
Energy, especially from fossil fuels, is a key ingredient for all sectors of a modern economy and plays a fundamental role in improving the quality of life in less developed economies. In 2007, India is ranked fifth in the world in terms of energy demand; accounting for 3.6% of total energy consumed, and is expected to grow at 4.8% in the future. India imports 70% of the oil it uses, and the country has been hit hard by the increasing price of oil, uncertainty and environmental hazards that are concerned with the consumption of fossil fuels. In such context, bio energy constitutes a suitable alternative source of energy for India, as large amounts of raw material are available to be harnessed.
Some of the ways we try to combat Climate Change differes from region to region and culure to culture. One of the remedies that seems to be adapting all around the world is the use of biofuels instead of using fossil fuels. People believe that instead of digging up and using oil and petroleum, our best solution to combat greenhouse gases emitted by fossil fuels is to plant soybeans, sugar cane, palm oil and use that as a replacement. More cars are flex fuled, and use ethenol mixed with petroleum to lessen the use of oil since oil prices are only going to increase with the decreasing amount that is
With the increases in the global population and the increase need to feed this population, comes the great debate in how governments of the developed and developing world must tackle this important issue. In his article, The Politics of Hunger: How Illusion and Greed Fan the Food Crisis, Paul Collier examines the root causes of the food crisis and three ways (the slaying of giants) governments can easily come in finding a solution in the near-term, middle-term and long-term. The root causes, as outlined by Mr. Collier, are the increasing demand for food and increases in food prices. First, Collier states, “the first giant that must be slain is the middle to upper-class love affair with peasant agriculture.” In other words, increasing commercial agriculture and farming. Second, Collier states that the lifting of the genetically modified foods (GM crops) ban by Europe and Africa will allow a decrease in global food prices. Lastly, he states the United States must lift the subsidies on corn produced for biofuel and find an alternate biofuel source (like Brazilian sugar cane), thus decreasing the price on corn produced for food while increasing overall grain production.
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/ &
