Hybrid Cars
In my basic presentation, I examined the practicality of HEVs (Hybrid Electric Vehicles), otherwise known as hybrids. The presentation gave some background about laws pertaining to emissions but at the same time was designed more to educate the consumer as to what a hybrid actually is. You do not plug it in!
Current Emission Standards are confusing. At this point in time, we are at a major transition as to what will be the future of combustion vehicles. Present day standards do not call for the kind of emission requirements that will account for the current rate of global warming. To fix this problem we must either cut back on the number of vehicles on the road (not likely to happen) or use less fuel. There are many advantages to efficient fuel consumption. These advantages range from saving money to saving the environment. It will also make the United States stronger as a nation in that we can reduce dependency on foreign oil.
The first question we ask ourselves: what is a hybrid? A hybrid is a vehicle that has both a combustion engine as well as an electric motor. With the batteries of today it is not possible to make a practical vehicle that will run solely on electric. These cars need to be recharged after a range of approximately 60 miles. This limitation does not make the car practical by today?s standards. Although, the number of hybrids on the road today is limited, in the future we should see most, if not all, passenger vehicles available with the hybrid option (an option that might very well become a requirement).
The primary goal of the hybrid vehicle is to cut down on global-warming. The only way in which we can effectively reduce green house gas emissions is by burning less fossi...

...eir combustion counterparts. However, this will change once they become popular and, in actuality, the additional cost up front can quickly pay for itself with increased fuel savings. There is also the question of all these batteries. If the nickel metal hydride batteries aren?t disposed of properly, there could be environmental side effects. Who will fix these cars? Currently, a hybrid will have to be brought back to the dealership for maintenance and that could prove to be more expensive than a private mechanic. However, as hybrids become more popular and costs drop, so will the associated maintenance fees. With the benefits weighed against the drawbacks, it is clear that hybrid vehicles are a plausible measure in controlling greenhouse emissions.

Increasing environmental awareness, coupled with a responsible American government and improved technology, have all contributed to the comeback of low-and zero-emissions vehicles in the US. It remains to be seen whether the automakers and oil companies will once again work to halt this progress, or embrace it as the technology of a more responsible future.
The Narrative of the Life of Frederick Douglass is an autobiography written by Frederick Douglass himself. No one knows the hardships and difficult times that Frederick Douglass went through as a slave, better than himself. That is why Frederick Douglass is considered to be, in my opinion, is the most reliable author when it comes to telling the story of his life as a slave.
In 1871 the nation of Germany formed under the 2nd Reich. Soon after this German nation would begin rivaling the superpowers in Europe of the time. By the beginning of the 20th century, Germany under the leadership of its kaiser would challenge the British Empire for the top power in Europe. In 1914 Germany would throw its self into a war which would end in chaos for its people. The following years after brought hardships that would strike the new Weimar Republic, creating a breading ground for extremists groups. These extremist groups came from both ends of the political spectrum, and were able to push their ideas based on the fears of the middle and upper class, and the strife of the down and out working class. The party that would benefit the most from the events occurring from 1871 to 1933 was the NSDAP lead by a charismatic Adolf Hitler.
Driven in large part by global initiatives and the potential for stringent regulations, the past decade or two has seen a marked increase in the importance of improvements with respect to environmental standards, including emissions and increases in fuel economy. In 2002, Cummins Emissions Solutions was launched after the need was identified for an emission solution that would help engines meet future regulations. In 2006, Cummins pioneered a hybrid diesel-electric bus which reduced fuel consumption and greenhouse gasses by more than 30 percent and me...
...igned it would still be three years and thousands of American men and boys, black and white, before emancipation was finally achieved. Douglass had written about the heinous crimes of slavery to expose the defense of these immoral acts by Southern plantation owners, and to strongly urge the people of the Northern states to push for abolition of slavery on American soil. By doing this Frederick Douglass along with his abolitionist comrades accomplished their goal and made America, in the words of Francis Scott Key, "a land of the free". A land with freedom for all races and nationalities.
Pollution is a major problem for all of us. People need to recognize this situation so we can start making a difference to this problem. In order to start making a difference, the federal government should increase gasoline tax by one dollar a gallon. Fifty percent of this dollar will go towards public transportation, since passenger cars and trucks are a major contribution towards air pollution, according to the United States Environmental Protection Agency, E.P.A (10/4, http://www.epa.gov/autoemissions/emsns.html). Due to the expected increase after this is put forth, the remaining fifty percent of the dollar will go towards safety on these transits. When public transportation increases, air pollution will decrease, which will lessen the harmful health risks towards the environment.
The Narrative of Frederick Douglass by Frederick Douglass is written to have people place their feet in the shoes of Frederick Douglass and try to understand the experience he went through as a slave. Douglass writes this piece of literature with strong wording to get his point across. He is not trying to point out the unpleasant parts of history, but to make people face the truth. He wants readers to realize that slavery is brutalizing and dehumanizing, that a slave is able to become a man, and that some slaves, like himself, have intellectual ability. These points are commonly presented through the words of Douglass because of his diction.
The confines of ignorance and both physical and mental abuse kept slaves from self discovery and rebellion. Frederick Douglass provides the journey of life as a brute to a free man. Frederick Douglass’s new identity included having a wife, a job of his own, a house, and the goal to reach out and help the people that were still stuck in slavery. From the rock bottom life of a slave he built himself up and became a successful
...rther then the end of 2010, the introduction of the electric car is not far to come. With proper government regulations and consumer knowledge, adoptability of the electric car is possible. However, one can drastically differ in opinion as to why the required elements to support such a vehicle were not readily planned to facilitate such a change. The inadequacies draw wavering concerns for both consumers and business looking for the return of value and profit. The larger picture needs to be remembered in which oil is not a renewable resource and results in pollution and environmental hazard. Consumers and business must work together to overcome the roadblocks down the road and support each other in the introduction of and future of the electric car. Adjustments will have to be made on both sides to ensure success and minimize the society and economy disruptions.
...essence of his reasoning. Douglass’s example of Aunt Hester’s whipping moves the audience to tears and persuades them to sympathize with the character. He accomplishes his goal when describing his own abuses during the practice in which he enlightens the reader on the subjects of freedom and justice. As a result, Douglass is successful in persuading readers who are ignorant of slavery’s injustice and savage barbarity. Even after this narrative, Douglass continued to refine the ideologies of many people. He became a lecturer in abolitionist meetings such as the Massachusetts Anti-Slavery Society. After the Civil War, Douglass fought for both women and African American rights. His autobiography is a small step for a greater result.
Most American cars are not hybrids or fuel-efficient, they are usually big SUV’s or trucks that get eighteen to ten miles per gallon. Most of Hondas, Toyotas, and Hyundai’s get around 20 to 30 miles per gallon, and hybrids get 50 miles per gallon. Peoples demand fuel-efficient cars because oil is i...
Hybrid cars use both gas and electric. The gasoline engine is the primary source of power, while the electric motor is used at low speeds. Emissions levels are reduced because the gasoline engine shuts off at low speeds. An additional benefit of the parallel configuration is that no outside source of electric power is required because the engine itself generates the required electricity. A Hybrid Electric Vehicle known as HEV have several advantages over traditional internal combustion engine (ICE) vehicles: Regenerative braking capability, which helps minimize the energy lost when driving. Engine is sized to average load, not peak load, which reduces the weight of the engine. Fuel efficiency is greatly increased, while emissions are greatly decreased. HEVs can be operated using alternative fuels; therefore they need not be depended on fossil fuels (http://www.ott.doe.gov/hev/what.html#hev). Another great thing about these machines is the mpg; on the average, a hybrid car gets anywhere from 55-70mpg on the hwy. This is what makes the car all worth having. Now all this sounds good, but there are some issues that must be addressed.
Today, people use their own personal vehicles to travel more than ever before. Personal transportation is no longer considered a luxury; it is now considered a necessity. The number of cars in the United States has been growing steadily since the 1970s. The number of miles traveled by cars has risen nearly 150 percent, yet the United States population has only grown roughly 40 percent during that time (hybridcars.com, Driving Trends). Although it may seem like we are advancing into the future, in reality, we are moving backwards from the effects these vehicles have on our bodies and the environment. The pollution produced by these vehicles has brought us to the day where we must find other modes of transportation that cause less harm to the world in which we live. Advances in technology have developed hybrid vehicles to try and slow down the amount of pollution. Driving a hybrid vehicle, instead of a conventional gas powered vehicle, can reduce the amount of pollution that affects our lives and the environment around us.
In this case study I will be discussing advantages and disadvantages of electric cars. Electric cars are cars that are powered by electricity. Electric vehicles are an important part of cutting emissions and reducing global warming. The battery of an electric car stores electrical energy. The electric motor is coupled to the wheels through gears; it converts 59-60% of electrical energy into the wheels. The battery runs the motor which allows the car to move. Electric cars are necessary as they will save money, because electricity is cheaper than gas. Also electric vehicles will help reduce global warming and pollution. However, some people say that electric cars still have environmental costs. The electricity used to recharge EV batteries has to come from somewhere in the world, and now, most electricity is generated by burning fossil fuels. Although electric vehicles are classified as green cars, purists will not appreciate the toxicity of the batteries.
Electric cars help lower emissions because they have completely clean motors. As time progresses, emission standards rise and will become harder to meet for automakers. Electric motors will always have zero emissions and auto makers won't have to spend extra money to make their engines cleaner and more fuel efficient. Originally, when the internal combustion engine was invented, pollution wasn't a problem. After hundreds of years and the many combustion engines created, all the exhaust has built up. Today, pollution is one of the largest problems in our environment. Every year the average miles driven rises for everyone. When this rises, the pollution rises as well. Toni Marzotto, in "The Evolution of Public Policy: and the Environment," explains how air pollution will continue to keep on increasing:
