Biofuels
Biofuels were the first liquid fuel, which include oils, animal fats, and ethanol from crops (Kovarik). They use alternative sources of materials to create fuels, which can be a key feature for our future. Our economy uses some of the dirtiest and most harmful materials to create our fuels and everyday uses, which is slowly hurting our environment. The use of biofuels can save our money spendings, and have more of what we need to survive. People say that biofuels are not healthy for our environment, but in reality they are stronger and more efficient. Although many believe that biofuels are an unnecessary fuel source, biofuels are important for our environment; therefore, biofuels must be used as our alternative source of fuel, and

Biofuels are not only used in foods, but can be used in many other ways such as transportation. According to research, energy that is created by biomass is less expensive than using coal/oil. Biofuels work just as much as fossil fuels but use about ⅓ less than fossil fuels do (Biomass Energy). Biofuels are commonly mistaken as an unhealthy gateway, but it is inexpensive compared to using coal and oil. Biofuels also use a high number of pipes stretching across states and even countries, but with biofuels the need for these pipes won't exist. Many people have not even heard of biofuels, so they just assume it's not necessary or needed to survive. What they don't know is that it will give them a better living environment, and maybe a decrease in the price of gasoline, foods, etc. People need to hear about what biofuels can do to the environment, and hopefully more people will agree that biofuels can be used as a substitute for other harmful fuels. Biofuels can be made simply and will be a faster way for us to create ethanol which is a key factor in the making of gasoline. To create biofuels they use the non-edible parts of plants which is a bigger bulk of the plant so it can create more than what is used now. Equally important, roughly

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.
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.
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...
One day I pulled up to a gas station, and to my surprise I saw a new sticker on the pump. The sticker read,” Fuel may contain 10% Ethanol.” I was a little taken back by the sticker. I didn’t have a full understanding of why ethanol was being used in the fuel for my car. I knew that ethanol was a bi-product of corn and other plants, so I found myself asking the question, is corn for food or fuel? I got back into my car and returned to the freeway with this question on my mind. While driving I started noticing stickers and labels on other vehicles that read: CNG (compressed natural gas), Flex Fuel (allows vehicles to go between 2 different fuels), HEV (Hybrid Electric Vehicle), and Bio-diesel (cleaner burning diesel fuel, made from plants or vegetable oils). As I pondered about the various labeling, I found myself most curious about ethanol and other bio-fuel products.
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...
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; ...
Secondly, the use of biofuels is not a cost effective option as they are more expensive than fossil fuels. According to the County Commissions of the US Department of Agriculture and North Dakota State University, there are around seven biodiesel producers in the US. Biodiesel is the mix of biofuel and diesel in 20:80 ratio, which means that the cost of biodiesel will be around 20$ more ...
Biotechnology is a growth field that consists of the use of biological systems or living organisms in which technology is developed and applied1. Take a look at IBB in figure 1 below it shows an increasing upward trend in the past 5 years showing the fast expansion and growth of the bio sector. One of the significance and importance of biotechnology is that it covers almost every field. The application of biotechnology can be used for industrial, agricultural and medical purposes. The study of microorganisms and particles can be beneficial to mankind. With a clear understanding of internal body composition and molecular behaviour, vaccines and medications can be produced to treat diseases and conditions. Fruits and vegetables can be modified to grow faster, taste better, resist different temperatures, repels insects, etc2. Although biotechnology has the potential to affect modern society and have a positive impact on the environment, the misuse of such technology can lead to devastating consequences and side effects. The creation of bioweapons, food toxicity, errors in products and many ethical issues are also to be considered with the development of such technology. However, the upside and potential breakthrough in this technology could feed the hungry, reduce environmental or human footprint, develop cleaner and more efficient energy sources, etc. On top of this, the emerging applications in the biotech sector is creating plenty of opportunities for businesses that offer biotech related services for other organisations to make use of3. Examples of these applications and subjects include combinatorial chemistry, bioinformatics, biochips, proteomics and high-throughput screening. However on of the most looked at, compelling and c...
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
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.
Green technology is the technology whose main aim is reduce the impact of human activities on the environment. In other words the target of green technology is to consume less natural resources, reduce the emission, produce goods with energy efficiency, take care of health and safety issues and reuse and recycle the goods after their usage.
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.
Biotechnology in food uses genes of plants,microorganisms and animals that have desired production or nutrition related characteristics. The tools that are used in food biotechnology include traditional breeding ,such as cross breeding,and many modern techniques that have to do with using what is known about genes or orders for specific traits to better the quality and quantity of plant species. Food biotechnology modifies the production of fruits and vegetables that ripen on the vine for a better fresher taste. Different type of foods also benefit from food biotechnology .Foods that are developed using biotechnology are studied very carefully and judge by many governing agencies, health expects and scientists all over the world. Biotechnology can assist in the improve ment of the safety of food by reducing the naturally occurring toxins and allergens in different types of food .Food biotechnology is one of many tools farmers and food producers can use to give a food supply that is affordable,safe,convenient and sustainable
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
