Rapidly the world is succumbing to climate change, a problem that is becoming more disastrous day by day. The use of Fossil Fuels throughout the years has created this issue and now the people of the world need to fix this problem. The solution is renewable energy. Therefore, the alternative energy source, Biomass, combined with an Algae Biofuel energy source would best benefit the community in Yuma, Arizona. Biomass and algae biofuel would work well together in Yuma, Arizona because biomass has a fairly good energy efficiency of 22-40%(Electricity Generation Reading),

To convert algae into a biofuel, first oil is extracted. An expeller is used to extract oil from the algae. This extracts about 70-75% of the oil. Next, hexane is utilized like a solvent to extract up to 95% of the oil. Supercritical fluid extraction is then used to extract the oil even more. Finally once the oil is completely extracted, the hydrocarbon chains in the oils are broken by hydrogen. Finally this creates a green, crude oil which can be used as fuel when put under heat(http://sks.sirs.com webapparticleartno=0000283550& type=ART%20(SIRS%20Issues%20Researcher)). The energy transformation and transfer that occurs is solar energy from the sun is transferred to the algae to help it grow. Then when pressure is put upon the algae, it transforms solar energy to chemical energy allowing it to be stored as an oil. Finally, when this oil is utilized it can be transformed into electrical energy. On the other hand, to produce biomass, waste is burned to make a steam that turns a turbine. Then this generates electricity and gives homes and industries heat. This is a kinetic energy to electrical energy transformation because the turbine is a generator which uses motion to power electricity. There are many advantages and disadvantages to producing algae biofuel as well. For example, algae uses large amounts of carbon dioxide, which will decrease the carbon dioxide on a large scale. Thus, …show more content…
This could be seen as a disadvantage because biomass production also requires a good amount of water to produce crops and other materials that are used to make biomass. Therefore, the people of Arizona could potentially suffer from water shortages and droughts due to the loss of water used to power both energy sources. However, this isn’t the case because algae can also be grown in ocean water, that has a much larger supply, which is right next to Arizona. Therefore, this problem can easily be solved because algae thrives in brackish water, ocean water, and freshwater. This means that the people of Yuma, Arizona would only need to put some of their water into biomass production instead of both
Texas is known for its agricultural land, especially in West Texas, and can expand biomass energy and reduce the use of non-renewable resources. For example, “Texas also has several biogas facilities that recycle organic waste into renewable energy” (U.S. Energy Information Administration, Page 4). 8 Not only is this energy source renewable but it is recycling waste into a valuable resource. Texas “also has eight biodiesel plants that can produce about 380 million gallons of biodiesel each year” (U.S. Energy Information Administration, Page 4). 9
Looking at the difference of ethanol fuel and gasoline, the benefits of ethanol fuel by far outweigh gasoline. With ethanol fuel being made from biomass the amount of greenhouse gas emissions is greatly reduced from those of gasoline emissions. This is allowed to happen because when ethanol fuel is burned, it is burned in almost complete combustion making the emissions much more clear and less harmful to the environment. With a reduction of greenhouse gas emissions the benefits to the environment are huge. Our economy would be allowed to spend less money on environmental factors and more for the people.
In Florida, electric utilities use natural gas as their main source of generating power. In 2015, Florida generated 156 Terawatt hours of electricity from natural gas (PSC). This vastly overwhelms other sources such as coal, at 47 TWh, nuclear, at 28 TWh, renewables, at 3 TWh, or oil, at a meager 592 GWh (PSC). This excessive use of natural gas puts the majority of Florida dependent on a resource that probably will not be around in a hundred years. The capacity of Florida’s renewable sources is rather disappointing.
Considering the amount of water and energy that the Colorado River is able to provide to so many areas, we need to also consider the risk of a permanent destruction of this natural resource. We need to find other resources such as solar, and wind energy to substitute the use of fossil fuels. In particularly for the areas were the Colorado River is located, Solar Energy could be a great resource. They are several of semi-arid desert are located throughout the area of Colorado. In 2007 “The Nevada Solar One” was able to build a Solar Plant providing employment for over 800 people, and after the construction was completed.
There, the algae in the water will use these substances to grow rapidly, and there will eventually be a high concentration of algae in the water. When the algae eventually dies, it is broken down by bacteria, which multiply and use up all of the oxygen
Global Warming Proposal Introduction The phenomenon of constant increase in the earth’s temperature is known as global warming. The excessive use of fossil fuels is destroying our environment as well as wildlife. It is a great threat to human life too, as this activity is causing intense pollution and also results in damaging the ozone layer.
