Recommended: Fossil fuel alternative
The increased use of nonrenewable fossil fossil fuels which are nonrenewable and awareness about environmental changes has been led to the development of fossil fuel alternatives such as biofuels which is , a renewable resource. From In the past few years, the researchers have been applied various methods and examined various feedstock biomass feedstock’s such as corn, sugar cane, canola, soybean and lignocellulosic crops for the production of biofuels. The primary drawback of these first and second generation biofuels are the high usage of agricultural land. which This can lead to the a food crisis, high water usage, and high production time. The An alternative solution to the current situation is is the production of biofuels from microalgae. Microalgae are single single-celled organisms that grow in a wide range of aquatic environments , from fresh water through saturated saline and have the higher lipid content compared to what?. MicroaAlgae have the capacity to produce and accumulate energy-rich oils, have natural ability to accumulate oil in its dry biomass. The genetic diversi...
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).
Biogas is a clean environment friendly fuel. Raw biogas contains about 55–65% methane (CH4), 30–45% carbon dioxide (CO2), traces of hydrogen sulfide (H2S) and fractions of water vapours.
Both gasoline and ethanol have been around since the time of Henry Ford. Gasoline has been the more accessible of all of them. Ethanol and natural gas have been gaining more support over the years and now gasoline contains ten percent ethanol. Propane is mostly used in fleet vehicles. Cars today can run on gasoline with a little ethanol, but too much ethanol can severely damage a vehicle. Only flex fuel vehicles can handle more than ten percent ethanol in a system. Natural gas vehicles are starting to come onto the market. All three fuels have their pros and cons, but the ultimate decision is up to the consumer.
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.
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...
The dependency on fossil fuels is a pressing issue for not only America, but the whole world. People everywhere continue to search for solutions to the growing problem by taking steps to create a cleaner environment, reduce the price of fuel consumers pay and most importantly, protect the nation’s security from foreigners. America, being one of the leading consuming nations of fossil fuels, is negatively affecting the environmental, economic and political aspects pertaining to its dependency on non-renewable resources.
Fuel is material such as coal, gas, or oil that is burned to produce heat of power. Energy is an indirectly observed quantity. It is often understood as the ability a physical system has to do work on other physical systems. Fossil fuels are the natural substances made deep within the Earth from the remains of ancient plants and animals. Fossil fuels can be created when organic deposits from millions of years ago break down and decompose. This material can then be burned to create energy. Fossil fuels include coal, peat and petroleum oil.
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.
Reading up information and searching for clues (which were not extremely easy), turns out to have broadened my knowledge on Nature and Biomimicry itself and that there are so many people already using wind turbines to harvest the winds energy and know how the world can be saved. Therefore I have come to the conclusion and have seen that my hypothesis has been proven right.
Biodiesel is a non-petroleum based abettor ammunition which consists of the address alkyl esters of continued alternation blubbery acids acquired from renewable lipid sources. Biodiesel is about produced through the acknowledgment of a vegetable oil or beastly fat with booze in the attendance of a agitator to crop glycerin and biodiesel (chemically alleged methyl esters).
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
Biogas has been found to be a sustainable source of energy which is creates less emissions compared to coal and oil (1). Due to everyday needs and wants of the growing populations of the world, natural resources have been used and over used to a point where they are no more as available, such as fossil fuels in Kristianstad(2). This unfortunately creates concern for the future however, an alternative source of energy has been found and is being implemented in the Swedish city so that the strain on the over use of natural resources can be relieved(3). Biogas is produced from biomass and it is the best sustainable plan as a source of energy and a way to be more environmentally conscious(4).
Developing countries are characterized by rapid industrialization and a high population growth. As a result, the amount of generated organic wastes has increased. With the predominant methods of waste disposal, incineration and landfilling, there are problems associated. Incinerators produce flue gases containing bioaerosols, which cause environmental pollution. Though the use of landfills has been termed as efficient and to some extent environmentally friendly, most developing countries lack sufficient landfill capacities to handle the generated waste effectively. For example, according to the research conducted by Gautam, Baral and Herat (2009), when Gorkana, the largest landfill in Nepal got filled up, the waste management authorities started dumping wastes along the banks of River Bagmati. Conversion of organic wastes to biogas through anaerobic digestion offers the best solution to organic waste management (Zhang et al. 2014). Similar trend is seen in Malaysia where the landfills are almost reaching their life span due to improper management (Jereme 2013). This technology does not only provide disposal solution but also acts as an alternative to the existing sources of energy thus boosting the overall available energy for economic activities (Zhang et al. 2014).
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.
Why do we need to rely on renewable sources? Most of the energy that we use today come from fossil fuels such as natural gas, coal, and oil. All of these resources are non-renewable, it can finish one day. In order to have a better world and a healthy environment for the future, people are trying to obtain energy from natural resources instead of non-renewable sources. In the lecture “Renewable energy resources” (2014), Mistry focuses on some advantages and disadvantages of renewable energy. There are different kind of resources that we can use in order to produce renewable energy. Solar power, wind power, hydroelectric power are just some of the kinds of renewable energy that might be the best options to obtain energy because they come from
