Hybrid Vehicles and Earth's Changing Climate Essays

Many people buy hybrid cars because they have been told that hybrids are much more eco-friendly than any other vehicles out on the market and they feel proud for supporting the Mother Nature. Surprisingly, it is a fact that a recent report announced that the Toyota Prius has a higher life time energy cost than Hummer H1 SUV (kentlaw.edu). It also states, “There are, however, environmental costs to mining and smelting (in Canada) 1,000 tons a year of zinc for the battery-powered second motor, and the shipping of the zinc 10,000 miles - trailing a cloud of carbon - to Wales for refining and then to China for turning it into the component that goes to a battery factory in Japan” (kentlaw.edu). In other words, the hybrids emit less carbon dioxide and other gases but it releases far more energies and toxic gases into atmosphere at production and disposal stage.

The author first explains what a hybrid is, stating “A hybrid is a cross between two established varieties of plant, animal… or technology.” She introduces the hybrid vehicle, a new form of technology that stands as a possible answer for a vehicle that is both energy preserving and safer for the environment. Before she dives into details of how the vehicle works, she enlightens the reader on what the article is about and the objective of the hybrid vehicle. Students enrolling in an engineering course in a post-secondary institution will be more

The second largest source of greenhouse gas emissions in the United States is related to transportation, the burning of oil to produce energy in a combustion motor. The combustion process inside of engines is what produces the carbon matter that is emitted into the air through the exhaust system on gas-powered vehicles. Gas-powered transportation is accountable for 24 percent of the global carbon emissions; this should not come as much of a surprise given the amount of urban sprawl that is being seen in the United States and across the globe. In the past decade, the Environmental Protection Agency, the United States government, and major car manufacturers have been working in conjunction to find ways to provide a “greener” form of transportation (EPA, 2011). This has included testing the use of hydropower, ethanol, natural gas, biodiesel, and electricity as a means of powering vehicles, which has led to the introduction of hybrid vehicles. Hybrid vehicles run on electricity and gasoline, the byproduct of oil that is generally used in the engine combustion process of vehicles (U.S. Department of

Some people have also adopted the hybrid car trend, although many people think hybrid cars help the environment as well. Hybrid cars still uses some form of a gasoline when it is being used, thus creating carbon dioxide emissions. Whereas, the electric vehicle produces no emissions.

On Edmunds.com.” Edmunds. Hybrid cars have been saving the world little by little, first off hybrid cars have an excellent gas mileage because they are powered by an electric motor and slight gas, which can go much more farther than gas powered vehicles(“What Are Hybrid Cars and How Do They Work?). Also it will not produce smog , which is a good thing for the economy and the environment, the other reason why they are good in gas mileage is because the are light and there aerodynamics (“Hybrid Cars--Pros and Cons.” ). Hybrid cars are changing the economy by using much less has and less oil, they are more likely to save you money on the long

The invention of the automobile was a great milestone in history. Without it many places or things would have never been discovered. Many people would’ve lost their life waiting for medical attention to arrive. It would’ve taken days or weeks to transport goods or medication throughout the United States. Now that we have the technology and research, we must take advantage, and suggest more methods in providing a better life for our future and are wildlife. Hybrid vehicles still have glitches as well as gas operated vehicles but it benefits savings in fuel and our environment will take time for science to make it more users friendly and less hazardous.

“Of the world’s approximately 650,000,000 motor vehicles, fewer than 1,500,000 are not powered by either gasoline or diesel.” (Bradley 24). This minority of the vehicular population equates to a mere two thousandths of a percent of alternately powered vehicles. Nearly all of these alternately powered vehicles are powered by liquefied petroleum or compressed natural gas. The time to change that for the better is here and we must push our way through the red tape created by automakers so we can finally drive practical low emission cars. It is imperative that we begin driving higher efficiency automobiles because the limited supply of fossil fuels is running low, global warming is becoming a major issue

“Automobiles have a large impact on the quality of our environment and public health. Automobile use affects virtually every aspect of environmental quality - including noise levels, air quality, water pollution, and urban sprawl. Ninety percent of the environmental impact of automobiles occurs through the operation of the cars: about 10 percent from the production, raw materials and disposal of

For a few decades, pollution has become an emergent hazard to the Earth. To solve that problem, human have been putting a great effort into filtering atmosphere, cleaning wastes from industrial factories, and making things greener. Waste from transportation is one of the most serious effects on environmental problems. It appears that scientists are searching for alternative fuels and evolutions in automotive industry, which must satisfy energy requirements and offer, at least, same performance compared to conventional car. The automotive industry, therefore, has turned to a new project, which is called hybrid transportation. This proposal presents how hybrid cars have developed and how that technology works in order to protect environment and save expenditure on fuel economy. Also, this will consider positive side of hybrid vehicle technology and its integration into society.

The purpose of this paper is to support the amateur research experiment in regards to the efficiency of combustion and combustion hybrid engines. A brief literature review on the effects of automobile use and production will help draw a conclusion as to whether hidden environmental effects outweigh its marketed green value.

First introduced in the 20th century, hybrid cars are expected to become the new generation of transportation in the future. These vehicles run on fossil fuels, gasoline, electricity, or a combination of those ones. Using “green energies” leads to a wide variety of advantages, including reduced dependence on oil, stabilized fuels’ economy, and lowered greenhouse gas (GHG) emissions and wastes discharged to the environment. Engineers, nowadays, have been spending a lot of effort on building and consolidating hybrid technology, so they are able to advance its performance, safety for customers, affability to the ecosystem, and especially the impacts of the hybrid on the auto industry. This paper provides some current studies on hybrid car and its effects on the environment, market.

Automobiles have since evolved and become almost a necessity for people. While they have become of major importance, they also hold many drawbacks to our environment. They are the leading cause of transportation emissions and they generate a majority of America’s global warming emissions. Even though air pollution emissions from motor vehicles have dropped considerably since 1950, Automobiles still produce about 60% of US transportation emissions and generate nearly 30% of America’s global warming emissions (Car Emissions and Global Warming). The average conventional automobile can be seen as fairly gas inefficient. Compared to a hybrid electric vehicle, conventional cars produce about 1.5 times more greenhouse gas emissions and costs more in fuel costs. Within a 100-mile trip, conventional vehicles produce about 87 lb CO2, hybrid electric vehicles produce 57 lb CO2, plug-in hybrid electric vehicles produce 62 lb CO2, and all-electric vehicles produce 54 lb CO2 (see table 1). This shows that hybrid and electric cars produce less greenhouse gas emissions and costs less for fuel, compared to a conventional pure gas powered vehicle.

In this day and age people argue more often about which kind of car is better overall; is it the internal combustion engine, ICE, or hybrid car? Consumers are led to believe through advertisements and online articles that hybrids are a better buy because of their reduced impact on the environment, and ease of use. These reasons are in fact false because hybrid cars are no better for the environment because of their production emissions and other variables.

The ABCs of a hybrid car are pretty easy, but the twist comes with comparing them to all gasoline cars. The main feature of a hybrid car is the engine. Until this era, the cars had just one engine which runs with gasoline; but know these hybrid cars have two engines, one is electric engine and the other is gasoline engine. These two engines of the hybrid car work as a gang, if electric engine needs help the gasoline engine will help the electric engine. The gasoline engine helps by charging the electric engine if it runs out of battery. This is how the hybrid car engine saves money on gas, and this process is environmental healthy. This process produces itsy-bitsy amount of harmful gases which is why this process is environmentally friendly.

One of the man-kinds biggest contributor to pollution is driving cars. Heavily populated cities, to be exact, are the most to blame for their horrendous living conditions. The pollution in Beijing has caused the city to be a hazard for anyone who breathes oxygen. According to an article from Forbes Magazine, “tiny carcinogenic particles known as PM2.5 reportedly at times are above 300 micrograms per cubic meter. The World Health Organization’s recommended maximum exposer is 25 micrograms”. Side effects such as early deaths, heart and lung problems, cancer, diabetes, birth defects plague the millions of people who live there. In a few years the city could find a simple fix just by switching to electric vehicles.
