The Effect Of Biofuels On The Environment Essay

We first started this experiment by obtaining twelve 15ml test tubes, in which we placed in a rack and labeled each with what

The first experiment begun by filling a 600-ml beaker, almost to the top, with water. Next, a 10-ml graduated cylinder was filled to the top with water. Once water was added to the beaker and graduated cylinder, a thumb was placed over the top of the graduated cylinder. This would ensure that no water was let out and no bubbles were let into the graduated cylinder. Next, it was turned upside down and fully submerged into the beaker. Then, a U-shaped glass tube was attained. The short end of the glass tube was placed into the beaker with the tip inside of the graduated cylinder. Next, a 50-ml Erlenmeyer flask was received. After, 10-ml of substrate concentration and 10-ml of catalase/buffer solution were placed into the flask. A rubber stopper was then placed on the opening of the flask. After adding these, the flask was held at the neck and spun softly

     "We need more stringent regulations on car emissions... Let's add MTBE to the fuel- that will reduce pollution... If people would just stop driving so much, pollution wouldn't be so bad..." People have long recognized the problems with the gasoline we used now.  We have tried everything from putting regulations on emissions, to putting additives in the gasoline (only to discover later that MTBE got into the groundwater), to campaigns to get people off the road.  However, more and more cars are on the roads as the population increases, and people are not going to stop driving.  Additives are as likely to cause problems as they are to prevent them.  Just changing the

Although burning biodiesel produce carbon dioxide, is does not contribute to global warming. This is because that amount of carbon dioxide that the growing plants take in during photosynthesis is the same as the amount of carbon dioxide that the diesel engine emits when it is burning the biodiesel. So there is no extra carbon dioxide added to the atmosphere. ( this makes happy who are against of using dieselfuels)

The environment is a hotly debated topic in today's society. Some of the subtopics that are going to be discussed are going to be those related to the way technology is changing, what industries are doing to help prevent further pollution, some of the methods used in paper recycling, and some discussion of renewable energy sources. For the most part, this section of the research paper, unlike the other sections, is going to attempt to discuss some of the ways the public has been dealing with, and are finding new ways to deal with environmental problems that we are presently facing.

Abstract – The world can’t be imagined without IC Engines ,as their applications are wider in various fields. And mainly used input for this engines are fossil fuels. But the challenge in this is decreasing rate of resources. The fossil fuels may not be available after some years if they used in the same way .Not only the fossil but also the electric power is the non renewable energy, This paper concentrates to run the engine without fossil fuels or electricity.

Then the first flask was removed and placed on a warmer till the temperature reached 35 degrees Celsius or 95 degrees Fahrenheit. The flask was then put back into the set up with the tubes connecting the solution to the water flask. Again four trials were done in intervals of 10 minutes apart with the data recorded. Then the solution flask was

If the experiment were repeated, some parts of procedure should be modified or improved to shorten the time of experiment and make the experiment more organized. Such as the Part A, Step 5; after heated up the test tube in the boiling water, used cold water to cool down the temperature of the test tube instead of cool it down spontaneously. By modified that it would save more time. Since there were so many groups doing the same step together, the lab equipment was limit such as the centrifuge. Students lined up in front of the centrifuge to wait for the others. Students could spread out to the different part of the experiment, some groups could start with Part A and the other can start with Part C.

The United States is the world’s largest producer of ethanol fuel, producing over 60% of the world’s ethanol in 2011, which correlates to the creation of the Renewable Fuel Standard (RFS) in 2005. The RFS originated with the Energy Policy Act of 2005 and was expanded and extended by the Energy Independence and Security Act of 2007 (EISA). The RFS requires renewable fuel to be blended into transportation fuel more so every year until it is set to reach 36 billion gallons in 2022 (Renewable). The purpose of this has widely been seen as an effort to combat environmental damage such as climate change and oil spills in addition to being a political move to be independent in creating our means of energy production. Currently, ethanol is societally regarded as an environmentally friendly fuel, being that it is produced from plant material through a series of chemical reactions. One of the most controversial issues relating to ethanol is the "net energy" of ethanol production. In sum, more energy is used to grow and process raw material into ethanol than is can be released by the ethanol itself. The agricultural practices that are necessary to produce the biomaterials that are converted to ethanol include planting, fertilization, tilling, watering, and harvesting, while processing the biomaterials involve transportation, fermentation, and distillation (Energy). While these processes require more energy than is able to be harvested from the resulted ethanol, and thus ethanol fuel is

The current use of energy in the United States, especially California, is foreshadowing catastrophe in our environment. Due to high demand of fossil fuels, the air is filled with more pollution every day. In addition to, it can increase the chances of having global warming. Since fossil fuels are generated from raw materials which are easy and cheap users are becoming extremely dependent on them. The main problem with fossil energy is that the supply of fossil fuels is not continuous. However, alternative energy is continual and harmless to the environment. Biomass does not pollute the atmosphere as much as natural gas. One of the most convenient alternative energies that are currently used for minor purposes is

Fuels have dominated the way the world operates for decades; with a rising demand for fuel becoming constantly more predominant. Their uses are vast, making them versatile and in high demand around the world. But since most common fuels like diesel and petrol are fossil fuels, the availability of such fuels is decreasing rapidly. Hence alternatives to these fuels are being developed and used worldwide. These alternatives include biofuels. Biofuels are defined as “a hydrocarbon that is made BY or FROM a living organism that we humans can use to power something.” (biofuel.org.uk, 2010) Most biofuels are made using forms of biomass, including algae, sugar cane, seeds, oil, fats etc. (biofuel.org.uk, 2010) Biodiesel is a biofuel alternative to

In order to have a great experiment and receive valid results, consistency and being able to maintain an order of methods and having alike testing subjects will produce greater results. It is important to follow procedures step by step, any mistake or any misplaced data will create a flaw on overall experiment. No data should be left out or ignored on the process of completing the experiment, every note and change is essential for the experiment. Leaving information half way or forgotten will confuse other researchers that try to duplicate or understand the experiment. If procedure is followed correctly, the chances for another duplication of the experiment can be made and the results will be successful.

Unlike gasoline or diesel, biofuels release little pollution. It can also be used to produce electricity by heating water using biofuels and using the steam produced to rotate a turbine. Another method is to allow the biofuel to decay and produce methane. Methane is commonly used as fuel for car, heating, cooking, and producing electricity.

Biofuels are combustible fuels created from biomass. Biofuels are just another type of energy. Biofuels are sources of energy, just as such as fossil fuels, wind energy, solar energy and geothermal energy. They are a renewable source of energy. Biofuels are made to ease all our energy needs. Biofuels are also expected to increase the sustainability of Earth’s other resources. Biofuels have

The American philosopher, ecologist and scientist, Aldo Leopold introduced in his book ‘A Sand County Almanac’ in 1949 the idea of ‘thinking like a mountain’. This basic and simple phrase was later analysed and further explored by environmentalist philosopher Arne Naess. He stated that thinking like a mountain consisted mainly in realizing that humans are part of the biosphere, therefore, mankind should be able to recognize several responsibilities towards all other living things, thus individuals must think first in the long-term interests of the environment (Buckingham et al., 2011). Thinking like a mountain is how enterprises, industries, nations, communities and even individuals should approach the realization of projects that could impact the environment. One must ask the fundamental question of knowing exactly what are the necessities of the habitats in a long-term time so that the right decision will be taken. However, probably and quite certainly, environmental aspects were not considered as a priority back in the 20th century when industries increased their profit by using cheap and efficient resources (compared to other sources of energy) such as coal, oil and gas to supply the energetic demand. Unfortunately, the uncontrolled and unsupervised exploitation of fossil fuels drove mankind to a period of time where climate change is one of the environmental threats humanity will face in a close future.
