Recommended: Essay on biofuels
Biofuel is obtained from lifeless or living microbial resources. Also, various plants and plant-derived materials are used for biofuel manufacturing. In order to be considered a biofuel, the fuel must contain over 80 percent renewable resources. An important process to generate energy, photosynthesis, is the main route through which oxidised carbon (carbon dioxide) is decreased in the daytime and oxidised back to carbon dioxide to generating energy in the night. Biofuel is originally derived from the photosynthesis process and can therefore often be referred to as a part of solar energy source.
Biofuel can be used as substitutes for conventional fuels e.g. petro fuels. Mainly, biofuel contains hydrogen and methane which are particularly derived from the microbial material. And these are...
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; ...
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...
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...

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
Biodiesel is considered an environmentally friendly alternative because it reduces the amount many toxic substances. Plants such as soybeans require carbon dioxide from the air to produce their stems, roots and leaves. During biodiesel production from soybean oil, carbon dioxide is produced and released in the atmosphere. Carbon dioxide is considered a green house gas (GHG). However, this cycle of GHG emission does not neccersarily contribute to the atmospheric carbon dioxide levels. This is because the next soybean crop will reuse the carbon dioxide emitted for its growth. Another important environmental benefit is that biodiesel reduces particulate matter (PM), hydrocarbon (HC) and carbon monoxide (CO) emissions. These benefits occur because biodiesel contains 11% oxygen by weight. Oxygen allows the fuel to burn better, resulting in fewer emissions from unburned fuel. And lastly, biodiesel fuels do not contain any sulfur and does not have an unpleasant smell when it is emitted from vehicles.
Microbial Fuel cells are extremely versatile, being able to work in a number of different environments with many different conditions. They can use almost all types of waste as long as it’s possible for it to organically decompose; it also does not require a further input of electricity or power. It does however require certain parts and certain bacteria, though many different types are currently being tested out in different research institutes to see which one is the most successful. This is a solar-based alternative energy as the bacteria consume the glucose that arri...
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.
Pros and Cons of Biodiesel Every day, oil is a topic that will make its way in the news, water dispenser chit-chat, and even family dinner conversations. Gasoline such is an essential part of people's daily comings and goings that it is difficult not to be affected by the increase of petrol prices, the fear of exhausting fuel reserves, and the effects petroleum has on the planet. All this concern over oil has brought out more interest in alternative fuels, including biodiesel. Biodiesel is one of the major biofuels, fuels made from biological ingredients rather than fossil fuels. Biodiesel is usually made from numerous natural resources, like plant oils or animal fat, through a series of chemical reactions.
The production of biofuels requires the cultivation, processing, and transportation of appropriate crops. Food production shares many of these same needs, and this conflict of resources has been the subject of numerous debates. The cultivation of crops for biofuels increases the consumption of natural resources and contributes to world hunger by redirecting the use of edible grains (Pimentel, et al., 2009, 9). We will look at 3 major points of debate on biofuel production: influence on food production, use of natural resources, and effect on the price of food.
Methane is produced in natural environments in a process called methanogenesis which is used by microorganisms as an energy source CO2 + 8 H+ + 8 e− → CH4 + 2 H2O. It is a fo...
Over the last two centuries, humanity has become increasingly reliant on fossil fuels. Over that time, the consequences of constantly burning fossil fuels have accumulated into a threat to industrialized cities. The burning of fossil fuels causes acid rain to shower on cities and ecosystems around the world, tormenting their inhabitants. The increasingly deadly pollution caused by the burning of fossil fuels has caused the deaths of many people around the world by causing respiratory problems. Not only has the pollution worsened, but the supply of fossil fuels is not limitless – as humanity’s reliance increases the supply decreases, and that is all the more reason to break humanity’s reliance on fossil fuels. Fossil fuels should be replaced with cleaner alternatives because fossil fuels cause environmental hazards, are non-renewable, and are detrimental to human health.
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.
The concept of this essay is to stress that biofuels are a viable and sustainable energy source than fossil fuels, showing its advantages but not ignoring its disadvantages which also enlightens us about the cleaner and renewable natural resources. Biofuels is an alternative source of energy which can end the global dependence on fossil fuels.
