fossil fuel. There are way too many deadly side effects of using fossil fuels especially at the rate we use them today. Some are terrible for our environment, economy, and society. The effects that fossil fuels are having on the environment are becoming more and more irreversible, soon there will be nothing that we can do to fix our mistakes. The change to renewable sources of energy will prevent further damage and be more beneficial for the environment, as well as the economy. Fossil fuels are…

ferment it, then becomes cellulosic ethanol which can be used to fuel automobiles. In this research paper I will be discussing switchgrass ethanol and why this interesting plant should be used as an alternative fuel source to using nonrenewable fossil fuels. Through the three chosen points I plan to argue the grass’s…

Fossil Fuels? Climate change and increasing levels of greenhouse gases have become an ever growing problem in the world today. There are many effects of climate change that have been documented from the latter part of the twentieth century until now. This significant change is due to the introduction of industrialization in society and how it has changed the equilibrium of the atmosphere by drastically increasing levels of CO2, a gas emitted from burning fossil fuels. We depend on fossil fuels…

source in this world. This is due to its variety kind of usage that will not only contribute to people but also towards any country that uses this source. For now, fossil fuel is widely being used as the primary oil in a lot of sectors such as transportation, production and manufacturing. As for that, we can conclude that fossil fuel is very important towards enhancing the growth of economy but with all of the advantages, there are also disadvantages. Some of the disadvantages are increasing…

What would you rather have clean renewable energy that does cause pollution or would you want energy that is not renewable and causes a lot of pollution and makes harmful environments? I believe that Geothermal energy is better than fossil fuels because it cost less, environmentally friendly, and can be accessed anywhere in the United States, also can produce almost the same amount of energy as most coals mines can. Geothermal Energy plants cost less over time they can pay off their debt because…

This paper discusses electric vehicles and fuel cells vehicles. Most people use fuel cells vehicles. We tend to think that electric vehicles is better than fuel cells vehicles. In particular, we think that electric vehicles can move using electricity without fuel cells and are environment conscious. Both of them have merits and demerits. I discuss the differences between them. Electric vehicles are propelled by one or more electric motors powered by rechargeable battery packs. They have several…

1) The combustion of fossil fuels has a negative impact on the global carbon cycle. This is because when fossil fuels are burned they give off carbon emissions. With the combustion of fossil fuels growing, more and more carbon is being put into the global carbon cycle which is going to cause global warming-a negative effect. Therefore, the combustion of fossil fuels is having a negative impact on the global carbon cycle. 2) Predicting our future oil supply is controversial and involves some…

High temperature proton exchange membrane fuel cells (HT-PEMFCs) are a promising clean technology, especially for automobile applications.1 These devices generate electricity from the chemical reactions that occur in the anode side of the cell, using H2 as a fuel and generating heat and water as by-products.2, 3 However, experimental studies using HT-PEMFCs show that degradation of the cell can occur after certain hours of operation (around 500 hours).4 Some of the factors that contribute to the…

Jet fuel consists of about 30% to 40% of an airline's expenses, giving good reason to do everything they can to try to increase the efficiency of their fleet. There are many factors that go into how much fuel each plane uses. since a plane uses more fuel during takeoff and climb, the climb is a bigger part of a short flight vs. a longer flight where it will be at cruising altitude longer. It takes fuel to carry fuel and a 747 filled to the max with over 6500 gallons of fuel weighing 6.8 lbs…

Polarization curve Fuel cell creates 1.16 V of equilibrium potential between hydrogen and oxygen. However, the actual open circuit voltage is around 1 V due to temperature, pressure, and the concentration of the reactant. The ohmic loss is the resistance loss induced by the unique resistances of the component of fuel cell. And the concentration loss occurs when reaction rates of hydrogen and oxygen are faster than their supply rates. (1) The diffusion flux created according to…
