The need for renewable energy resources couldn't be more desired than now. The article "Contribution of Renewable Energy Technologies to Future Energy Requirements "was written in 1984, it explains what potential renewable energy could have on many nations. This article was written by D.H. Buckley-Golder, R.G. Derwent, K.F. Langley, J.F. Walker and A.V. Werd to allow us to understand why renewable energy resources need to be developed and used. The time for research and development of renewable energy is now.
The article "Contribution of Renewable Energy Technologies to future Energy Requirements" made several credible points, helping us understand what renewable energy is. As defined by the report, renewable energy is: Wind on shore and off shore, Solar, Geothermal, Wave and Tidal wave power. The report also states that Bio-Fuels which supply Biomass Systems are an Alternative and Renewable Energy.
Within the Introduction the authors identify and explain the importance of renewable energy. The recent work collected mentioned in the report was form the, "Energy Technology Support Unit" or ETSU. The ETSU uses inductive reasoning to explain what renewable energy sources are; and what contribution they could potentially have in upcoming years. The renewable energy sources described are portrayed accurately by the "Advisory Council on Research and Development for Fuel and Power" or ACORD. ACORD is a sub division of the Department of Energy. In the second paragraph on page 111 of the report, the second sentence demonstrates how renewable sources could be viable by using the United Kingdom as an example. The sentence states, "The technical potential of the renewable resources is about Â½ to 2/3 of the total United Kingdom energy presently supported by Oil, Coal, Gas and Nuclear."(Page 111) This statement is a valid point, but only if enough time, money and personnel are used in the correct logic. This compelling detail means that the impending energy would provide the United Kingdom a little energy freedom. This energy freedom would allow the United Kingdom to not panic if any petroleum crisis were to occur. This potential energy would also save billions of dollars that could be spent in other sectors of the nation.
Within the introduction there are also invalid statements as well as logical fallacies. In the first paragraph the first sentence is a hasty generalization. The statement is hasty because they cannot tell what the future price of fuels will be at that point in time. This statement is an educated guess on what might happen. Another logical fallacy is in the first sentence of paragraph two, also on page 111. The sentence states, "It has been recognized for some years that there could be a significant contribution from renewable energy sources." This statement is oversimplified because in the 1930's there were Wind Chargers which are similar to Wind Turbines and are a form of renewable energy. This fact is very obvious and most if not all people in the United Kingdom know this. The final sentence in the second paragraph on page 112 is a repeated statement from the first paragraph. This statement is not necessarily a logical fallacy but there is no need to restate this fact. Overall the introduction seems to tail off the main focus. The start of the introduction seems to be strong, but as you read on, the middle to end really doesn't support the idea behind the introduction. The introduction doesn't seem to transition well between sentences throughout the paragraph.
The use of Bio-Fuels has many variations as seen on the table on pages 119, 120 and 121. These potential fuels are an alternative form of energy, but still less harmful than oils and gas which are used every day. These tables give: Characteristics, Markets, and Conventional systems replaced. The authors give these headings and explain why they are important. This helps readers understand what renewable energy can do for everyone. These tables are excellent examples of facts. Each table is accurate and uses rational appeal to influence readers and to give possible potential uses. This supports the need and desire for further Bio- Fuel research and development. In table 6 on page 119 titled "Assessment of the future contribution from Bio-Fuels through the combustion of solid wastes." The authors make another strong push for Bio-fuels by explaining that these systems can run wastes as fuel. This means that these Bio -fuels are powered by using animal waste, human waste and also unused vegetation. The authors know that in Iowa there are many problems with excessive animal waste because of all the farms. Residents have complaints and farms can't do anything about it because they need to discard the excessive waste otherwise they could have health problems with the animals. The authors used rational appeal to explain this on the table. The state of development for these systems is now in production and has been since the early 1980's. The markets for these systems are domestic, industrial and commercial. The authors explain how these systems can be used in the different areas of residents. This means that these Bio-fuels systems can operate in suburbs, cities and rural areas. These systems do create a byproduct that can be sold as bedding and also fertilizer for crops and gardens. The authors point out this fact because it helps persuade buyers to invest in this technology so they can save money and also make money.
The problems that Bio-fuels systems have are: economics, availability and market development. These problems can potentially outweigh the benefits of having a biomass system. The authors explain that these systems are very expensive; each system is about $2-3 million. The return on investment is dependent upon how much energy is required to operate homes, farms or business. The return on investment will take a longer period of time if the power consumption is low. Availability of these systems is limited due to the rate at which these systems are bought. Most of the productions of biomass systems are produced overseas because of the popularity they have there. These systems are just starting to come over to America. Most Americans don't know what biomass systems are, or what they do. Market Development of the biomass system is slow because as limited availability for their systems the more expensive they become, which in turn means that less people can buy them. This dissipates the market for them. Investors won't invest if no one is going to buy these systems.
Solar applications like Biomass have sufficient potential. The authors point out that there is no quantity of solar energy. Table 10 on page 123 and table 11 on page 124 give examples of what can be done with solar energy. The authors point out that most solar system sales would be bought by private owners only. This is a valid fact because these systems can produce only so much power. The authors use rational appeal to inform us that there are certain days that solar power will help owners and certain days it will not. They explain that solar power could be used in small applications that will better serve the buyer. Table 11 on page 124, shows a possible application of using a solar energy system to heat hot water in a home. The possibility of using solar energy to heat a hot water system is outstanding in that conventional hot water systems require large amounts of power. This application will allow homeowners to cut down on their energy bill.
Solar energy systems have many disadvantages that the authors didn't mention. Table 10 on page 123 describes systems that could be potentially replaced by using solar energy. The problem lies that in today's top solar panel, the panels are only 5%-15% efficient. The sun provides more photons in one hour than the earth can use in one year. The idea is sound in that we should use sun light to help in some areas of energy usages. Today's panels won't be able to supply a home's energy need. If homeowners had a solar energy system installed, it would cost them nine times more than power supply by the electric company per kilowatt.
Wave and tidal energy is the most unheard of form of renewable energy. In the article the authors point out the possible usages for wave and tidal energy. Table 16 on page 128 explains what could be done with wave and tidal energy. In reality there is no wave and tidal energy being used today because waves can't supply enough force to move a turbine to produce power. Tidal on the other hand is a concept to which no one has an answer. There are only a few currents that could create a large enough force to move a turbine. These currents are in the middle of oceans. Right now the technology is not available to introduce wave and tidal into the market and do further research and development.
Geothermal might have the best potential of all the renewable energy's. Within the article the authors use rational appear to support geothermal technology. They show how geothermal energy is clean and what it replaces. This fast is an excellent point, because geothermal uses only water to turn a turbine. There are no byproducts that affect the land or water or air. The authors explain that right now the technology is feasible and could be put into production now. The author's use inductive reasoning to state that wherever there is a coal plant; it could be transformed into a geothermal plant. The authors give many possibilities in table 9 on page 122 of what geothermal could do.
Wind turbines are the most heard about renewable energy in the world. The author's realistic approach on the topic of wind turbines is evident. There scientific research on the development of wind turbines leads many to believe that this renewable energy is the best option. Table 13 and 14 on page 127 show what usages can be accomplished by using wind energy. Table 13 shows examples and possibilities of onshore wind power while table 14 shows potential offshore estimates. The use of table 13 is a valid fact that readers and investors can see. They use many examples to show reader and investors that wind energy is solid.
Wind power onshore and off shore is a great way to supply energy to homes, industry, and the grid, but the key to remember is that the more wind you have the more energy that the turbine will produce. Inland turbines will have less power produced because less wind makes it into the inland. Off shore turbines have the best potential for producing large amounts of power. The problem with them is that there are out in the water. They have less access and are harder to maintain. Keep in mind that the wind doesn't always blow. Some days are good and other is not. Wind turbines also can cost a lot of money; that depends on the size of energy you require.
Overall the entire article was pretty solid and correct. The author's use of inductive reasoning and rational appeal was throughout. In choosing renewable technologies make sure to research the topic before agreeing to buy anything. Renewable energy production is depended apron where you live or work. The time for research and development of renewable energy is now.
