Recommended: Biofuel advantages and disadvantages summary
Nowadays, people around the world are demanding for more sustainable energy source other conventional fuels such as coal, natural gas and fossil fuel for their daily activities. However, conventional fuels are categorized into a non-renewable energy source. Thus, to overcome this problem, an alternative fuel called as biofuel is used to substitute the conventional fuels. Moreover, biofuel can grow in interest in many developing countries by using “modern” use of biomass to produce the clean liquid fuels. The uses of biomass as a biofuel feedstock may offer new employment prospects for people that stay in that region. The biomass that commonly been used in biofuel is called as algae biofuel or oilgae, in which the oil that does not consist of toxic or sulfur contents in it (Demirbas and Fatih Demirbas, 2011).
Biofuels can be produced either by First Generation of Biofuel (FGB), Second Generation of Biofuel (SGB), Third Generation of Biofuel (TGB) or Fourth Generation of Biofuel. FGB is mainly derived from food crops where it had created an issue regarding on competition of food for...
There is a lot of talk about the world’s source of energy going on these days and people are starting to ask questions about our sources of energy. Is it environmentally friendly? Does it make sense economically? For years the world has been highly dependent on fossil fuels that are extracted from the ground. These fuels power things from power plants, cars, plains, and many of the other modern conveniences that we enjoy. There is a lot of energy expended in the extraction and transport of these fuels as well as many negative environmental impacts. Scientists are busy finding alternative ways to power our world that are cost efficient and ecofriendly. One idea that is being explored as an effective replacement is producing oil from algae. Algae have a high content of oil, about 50 percent of its weight, and science is finding a way to use it as a clean fuel source.
It is believed that the world's supply of oil will last until about 2040. If you think about it, that’s not too far in the distance future. Oil is running out fast and we need to think of an alternate energy source. When we burn oil, we release carbon dioxide into the air which causes the earth’s climate to warm; a temperature rise of 3.6 degrees Fahrenheit could have serious if not devastating consequences. In the United States alone 60 percent of each person’s carbon footprint comes from the goods they buy, while the other 40 percent comes from their energy use at home, driving, and flying. That totals out to be about 10 billion tons a year. There are other energy sources but let’s think about the environmental and energy benefits of algae biofuel. Algae was first explored as a fuel alternative in 1978. Gas prices had skyrocketed, and the government was looking to help ease the crisis. The Aquatic Species Program run by the National Renewable Energy Laboratory, researched high oil-output algae for biofuel. After testing 3,000 types of algae, the program concluded that the algae, if...
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...
In Thailand, fruit bundles have to be transported from the plantation to the mills and refineries, which are located in Krabi province. The Thailand government is using palm oil biodiesel to become more sustainable. They are trying to reduce the dependence on import and to improve energy security in the country. After analyzing the life cycle production of methyl ester, it was found that the three major energy consumptions is transportation, fertilizer, and methanol. There should be a reduction in the amount of fertilizer. Biodiesel should be used instead of diesel and fossil fuels, which are often used, for a more environmental friendly way. There should be non-fossil fuels to produce methanol. There should be efficient utilization of co-products, including fibers and shells to improve overall energy output (Pleanjai and
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.
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.
Fuel alternatives for the future are very important because, we need resources for life. We won’t have fossil fuels forever. It is important to start now. If we did not have any fuel alternatives how would the world be?
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.
...ch is used to replace natural gas. He also stated that, among the equipment used to burn the biofuel, the suspension burner have the ability to exceed 99% efficiency and whole-tree burner can reduce the cost of harvesting and handling woody fuels by about 35% (Brown, 2003). Moreover, the usage of bio-energy in long term is to provide a degree of ecological balance and climate change, avoid acid rain, reduce soil erosion and minimize water pollution (Gevorkian, 2007). Therefore, biomass is environmental friendly like solar energy. Based on the research that has been carried out regarding the synthesis of gas from biomass, the gas gasifies in the internal combustion engine. The relative energy density of synthesis gas is higher than the fossil fuel under certain conditions. In addition, the relative flame speed of synthesis gas can reduce the time for spark ignition.
than the industry has seen up to date, with nearly 25% of all natural gas produced now
Fossil fuels are an important part of life. When you turn on the lights, watch TV, or take a shower, the electricity that you are using is being generated by fossil fuels. The three types of fossil fuels are coal, crude oil, and natural gas. They all take millions of years to form, so they are considered to be “non-renewable”- eventually, the fossil fuels will all be used up. One dangerous biological effect of using fossil fuels is ocean acidification. Extracting and transporting fossil fuels can also be very dangerous. Environmentally damaging accidents such as groundwater contamination, land subsidence, and oil spills occur frequently. Global warming is another possible environmental effect. Fossil fuels have a crucial role in modern society, but since they are non-renewable and dangerous, we should reduce our dependence on them and explore alternative energy sources. Wind energy, hydroelectricity, and solar energy are some examples of renewable fuel sources. There are also many things that people can do everyday to save energy (and, in turn, conserve fossil fuels).
Biomass gasification is a process by which biofuel is produced. It has been used for over 180 years but in the last decades it has been reconsidered as an interesting technique due to the fact that oil supplies are decreasing. As mentioned before, gasification is a thermal process. Heat is added up in order to convert the organic mass to biofuel. The biomass usually undergoes drying, pyrolysis, partial oxidation and reduction. Nowadays the configurations used for gasification are three: fixed bed gasifier, fluidized bed gasifier and entrained bed gasifiers. The simplest configuration is the
In the process of extracting energy from the sun, algae may be the best organic intermediary, since they can double their size in a day, making them among the most efficient organisms at converting light energy into biomass. Oil is then extracted from the algae, creating a product almost chemically indistinguishable from light, sweet crude oil, except that it is green in color. From the thousands of algae species, those high in starch are best, since they need a good supply of carbon dioxide to grow at an acceptable clip, and they can feed on nutrients in sewage, raising the appealing prospect of producing fuel while treating sewage. They are aquatic, but can grow isalty or brackish water so they don't have to compete for the land and water needed to grow food crops.
Even though production of biofuels, such as ethanol and biodiesel, is rapidly increasing, their contribution to total fuel consumption will remain limited. Biofuels are sources of energy produced directly or indirectly from organic material including animal waste and plant material. In order to be considered a biofuel, at least 80% of the fuel must be made from renewable materials. There are 3 main types of biofuels: ethanol, biodiesel and biojet fuel. Biofuels are considered to be renewable since they can be replaced as quickly as they are used however biofuels biofuel production requires the use of fossil fuels in the form of fertilizers, agrochemicals,
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.
