Principles of speech
General Purpose: To argue
Specific Purpose: To argue the point that green cars aren’t any better than non green cars.
Thesis Statement: The government and certain car manufacturing companies shouldn’t be promoting energy conserving vehicles as zero emissions vehicles because 1) the process of manufacturing electric cars pollutes the environment; 2) recharging the car uses a tremendous amount of fossil fuels; 3)The cost to manufacture an electric and hybrid vehicle is tremendous.
I. (Attention Getter) The U.S. Government has wasted billions of dollars to develop electric cars to replace gasoline and diesel vehicles on the premise that they are “cleaner” for the environment. We have also been told that they are far cheaper to operate. However, new information reveals that the “green” cars may not be so “green” after all. II. (Justification) President Obama calls for 1 million electric plug-in cars to be on American roads by 2015 and it hasn’t happened for good reason.
A. While it appears that the goal is within reach in terms of production capacity, initial costs and lack of familiarity with technology could be barriers. (Keller)
B. Consumers remain wary of the cars’ limited range, higher price and the logistics of battery-charging. (Lomborg) III. (Credibility Statement) I work in the auto industry so I am intrigued when the industry and the government make claims for cleaner cars. Especially when they make claims about the zero emissions that electric cars produce. A. Electric and hybrid car technology has gained popularity for instructors to teach in the automotive classes. B. I have a whole section dedicated to subject matter of electric and hybrid technology in automotive class. IV. (Thesis Statement)The government, and others, should not make claims that hybrids and electrics are a cleaner and cheaper alternative to today’s gasoline engines. A. First, the lithium used in the ion batteries is incredibly dangerous and carcinogenic. B. Secondly, EVs do depend on fossil fuels for their electricity from outlets. C. Finally, an electric car has a limited range with a scarce availability of recharging. (Transition) My first argument will show that lithium batteries are dangerous mine and handle. Body
I. (Constructive argument)
A. The EPA has linked the use of extremely powerful solvents in the creation of lithium electrolytes and cathodes. (Braun) 1. Specifically, the cobalt used in the creation of the most energy dense lithium-ion batteries is poisonous and extremely carcinogenic. (Braun) i. Pulmonary, neurological, and respiratory problems have all been connected to cobalt exposure. B. While mining for lithium the nickel and cobalt ore is stripped from its solid state and depleted into the water source. (Braun) 1. Lithium extraction envetibly causes harm to the soil and also causes air contamination. i. The lithium is evaporated over salt flats near where it is mined and eventually it leaches down into the soil. ii. Pretty big impact on the environment while mining
(Transition):This argument will show that although, maybe cleaner out of the tailpipe, evs still need to be plugged in at the outlet and that makes these cars expensive to buy and charge. II. (Second Constructive argument) EVs that depend on coal for their electricity are actually 17 percent to 27 percent worse for the environment than diesel or gas engines, because we depend so much on coal for our electricity. So the cost of the coal will go up, because of demand. (Braun) A. This is especially true for the U.S., because we derive about 45 percent of our energy from coal. (Braun) 1. In states like Pennsylvania, Ohio, and Texas it’s around 100 percent. (Braun) 2. The global warming potential for EVs that rely on natural gas – generally considered to be the cleanest fossil fuel – show an improvement of only 12 percent over gasoline, and break even...
