Biofuels are becoming an increasingly important alternative to traditional forms of energy
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,

These would be: the cost, the fact that there is an unlimited supply of resources to make the fuel with, it’s a renewable source that benefits our environment and it leads to economic stimulation and. First of all, the cost is an advantage since biofuels have to potential to be significantly less expensive than petroleum or any fossil fuel. This is possible due to the increasing worldwide demand for oil. Meanwhile, the supply for oil is diminishing, making biofuels more desirable whilst the prices are constantly fluctuating. Whereas fossil fuels are limited since they come from specific materials years ago, biofuels are renewable (since you can always produce more if it runs out) and can be manufactured from a variety of materials such as: crop waste, manure and other byproducts. This takes recycling to a new constructive level. Likewise, the amount of carbon emissions will also decrease drastically since when biofuels are used, they produce significantly less carbon and fewer toxins. This also makes them a safer alternative in order to preserve atmospheric quality and lower air pollution. In terms of economic stimulation, the economy will find stability as when using biofuels you can disregard afore mentioned fluctuating oil prices due to change in demand. This is because biofuels are produced locally. This will also lead to multiple job opportunities, resulting less unemployment, which is incredibly advantageous economically. Biofuel productions will also increase the demand for certain crops therefore, providing economic stability to the agriculture
Pimental D and Patzek (2005). Ethanol Production using Corn, Switchgrass and Wood; Biodiesel Production using soybean and Sunflower. Earth and Environmental Sciences, 14 (1).
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.
Ethanol production was developed in hopes of severing our ties with fossil fuels in favor of alternative energy, such as biofuels. Although, VOCs emissions are released during production of ethanol in a factory, the quality of air is greatly improved when burning ethanol versus fossil fuels. Burning ethanol instead of fossil fuels reduces the amount of cancer-causing greenhouse gases that go into the atmosphere. Ethanol production ranks at the bottom of industrial water usage, but is still not out of the woods with the abundance of water usage needed in corn feedstock and ethanol manufacturing and processing facilities. Many acres of land are needed to grow corn crops, however, many corn farmers are successful in growing more corn on less acreage.
“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...
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
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.
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...
On April 20, 2010, the Deepwater Horizon oil drill exploded; thirteen people were killed and many were injured. 206 million gallons of oil was dumped into the Gulf of Mexico. This event attracted many new supporters of alternative energy (Issitt & Warhol). Alternative energy refers to any energy source other than fossil fuels. Fossil fuels are materials including natural gas, coal, and oil; they are cheap to produce, easy to distribute, and provide most of the electricity used in the world’s technology. However, they are nonrenewable, cause many harmful environmental effects, and take millions of years to create. Thus, many modern energy companies are researching new ways to develop alternative fuel sources (Issitt
The world is dependent on fossil fuels as the prime source of power to meet our energy demands. What are fossil fuels? “Fossil fuels come in three major forms-coal, oil, and natural gas. Because fossil fuels are a finite resource and cannot be replenished once they are extracted and burned, they are not considered renewable.” - (United States Environmental Protection Agency) When the supply of fossil fuels is completely exhausted, what will we rely on to meet our energy needs? An alternative option available that should be implemented more in our use is renewable energy, energy that can be replenished, such as solar, wind, and hydropower. - (United States Environmental Protection Agency) Even though the dependency on fossil fuels is tremendous,
Today our renewable fuel of the future is ethanol. Many of us know ethanol as E85 or other higher levels of ethanol blends. Ethanol is a renewable fuel made from various plant materials known as biomass. Ethanol is non-toxic and biodegradable. Ethanol is a clear, colorless liquid primarily made from corn,sugar or cellulosic feedstocks.The potential benefits of cellulosic feedstock is that it results in lower levels of greenhouse gases emissions into the atmosphere. Cellulosic ethanol use could reduce greenhouse gases by as much as 86 percent. In the United States, ethanol is mostly made up of corn grain. Ethanol is not meant for a fuel substitute but a fuel additive. Of gasoline
One of the most obvious benefits are a new source of clean and infinite energy. It is a fact that the Earth only has a finite amount of fossil fuels like natural gas and oil, so the day will come when there will not be any more fuel left to create the energy needed to power an entire nation. A nation that is less dependent on finite resources, such as oil and petroleum, is capable of saving a lot of money by not paying for fossil fuels and still powering the country. There is never a day when there is no water, sun, or wind to power a renewable energy source such as a solar panel, dam, or windmill. Surprisingly, renewable energy construction has also led to an influx in jobs.
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 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.
Secondly, whereas oil is a limited resource that comes from specific materials, biofuels can be manufactured from a wide range of materials including crop waste, manure, and other byproducts. This makes it an efficient step in recycling. Thirdly, it takes a long time for fossil fuels to be produced, but biofuels can be easily renewable as new crops are grown and waste material is collected. Fourthly, biofuels can be produced locally, which decreases the nation's dependence upon foreign energy. By reducing dependence on foreign fuel sources, countries can protect the integrity of their energy resources and make them safe from outside influences.
