For over 100 years, the automobile industry has relied on gasoline as its main source of fuel. Gasoline is a colorless, highly flammable substance used in internal combustion engines. It is a fossil fuel made from crude oil, a natural gas formed from the remains of ancient plants and animals (Webster‘s Dictionary). Gasoline has positively influenced our way of life by providing convenient, on demand transportation. It has created a global economy that moves people and goods faster and more easily than ever imagined (Povey 12). Although a seemingly perfect substance, it has unprecedented flaws. The tremendous political, environmental, and economic problems resultant from the excessive use of gasoline leads to the conclusion that the automobile industry should not continue to rely on this source of fuel. Environmental Risks When the problems with gasoline use are considered, the catastrophic environmental effects are the primary concern. Automobile use consumes 70 percent of the United States oil supply and is responsible for one-third of the nation’s carbon emissions (Lovins 173). This results in pollution, global warming, and health problems for the people, plants, and animals. The search for alternative fuel is powered by the increasingly evident environmental problems and long-term health of the planet (Povey 17). Fortunately, reducing emissions globally is predicted to have a positive effect and offset previous harms (Backer). As years pass and demand for gasoline increases, it is inevitable that the world’s oil supply will not last forever. This idea is made increasingly clear by evidence of peaking. Peak production is the point in time when about one-half of the world’s oil supply will be gone. Oil production in a given ... ... middle of paper ... ...Africa, simply to ensure a steady supply of oil for America. Finding an alternative fuel would be much safer, and much less expensive. Alternative fuels also do not fund a war against America. By paying for such large amounts of oil, America is funding both sides of the Islamic war; Middle East countries use American money to fight (Hobson). Alternative fuels allow America to keep to themselves and avoid conflict. Gasoline is thought to be a helpful substance to all countries worldwide. However, the negative effects are far greater than the positive. A diversity of clean fuels is vital for the political, environmental, and economic health of America. Although gasoline is a product depended on by the United States of America and many other countries, the negative effects are unbearable, dangerous, and unnecessary due to the opportunity to use alternative fuels.
Gasoline is one of the many conversation starters anywhere you go. People have different opinions on why gasoline prices are fluctuating at such a rapid pace. Some Americans have chosen a way of thinking towards the prices. Whether it be making up rumors or just plainly trash talking towards our government. You make ask yourself the same questions many economist do, why has the price of oil been dropping so fast? Why now? This a complicated question, but it boils down to the simple economics of supply and demand. Supply and demand means a relationship between how much of a particular product is available and how much of it people want, and especially the way that this affects the level of pricing. Now of course there would be a shortage of gasoline during the summer time when everyone is traveling
In 1908, the U.S. Geological Survey (USGS) predicted that the total future supply of U.S. oil would not exceed 23 billion barrels. In 1914, the U.S. Bureau of Mines predicted that only 5.7 billion barrels of oil remained. In 1920, the USGS proclaimed the peak in U.S. oil production was almost reached. In 1939, the Department of Interior declared that there was only 13 years of oil production remaining. In 1977, President Jimmy Carter claimed, “We are now running out of oil.” Despite these predictions, the U.S. has produced over 200 billion barrels of oil since the early 1900’s. (The Futurist, 1997)
In 2004, crude oil producers around the world expected a 1.5% growth in the world’s demand for crude oil. The actual growth rate was more than double the projections at 3.3%. This growth was due to rapidly industrializing of foreign countries such as, China and India. Therefore the lack of crude oil affected the supply of gasoline to consumers at the pump.
The United States has had several scares throughout its history in terms of oil, most turn out to be over exaggerations of a small event. However, these scares highlight a massive issue with the U.S. and that issue is the U.S.’s dependence on foreign oil. Why does it matter that our oil should come from over seas? In a healthy economy this probably wouldn’t be as relevant, but the U.S.’s economy is not exactly healthy at the moment. There are 4 things that I would like to address: what the problem is, how it affects us, what some solutions are, and what solutions I feel are best.
No more filling guilty about filling up your tank and driving through cities and towns spreading the harmful fuels from your gas engine. Biofuels are known for burning much cleaner

Wright, R. T., & Boorse, D. F. (2011). In addition to the rise in prices, another negative aspect of the U.S. dependency on foreign crude oil is the risk of supply disruptions caused by political instability in the Middle East. According to Rebecca Lefton and Daniel J. Weiss in the article “Oil Dependence Is a Dangerous Habit” in 2010, the U.S. imported 4 million barrels of oil a day, or 1.5 billion barrels per year, from “dangerous or unstable” countries. The prices at which these barrels are being purchased are still very high, and often lead to conflict between the U.S. and Middle Eastern countries. Lefton and Weiss also add that the U.S. reliance on oil from countries that are dangerous or unstable could have serious implications for our national security, economy and environment....
The future American commuter will undoubtedly have to transition from the use of fossil fuels to new alternatives due to the diminishing availability of the nation’s oil resources. How will America respond to this upcoming issue? It is difficult to predict which alternative fuel source America will ultimately choose, but with the premier of Nissan’s electric powered Leaf and other companies; such as Tesla Motors and Chevy, with their electric cars ready for market, the electric car may be winning the race to become the new standard for the gasoline alternative. Electric cars resolve long standing environmental issues, but it will need to maneuver around many roadblocks to become a marketable consideration for the general public. The cost of electric cars, currently on the market, makes them an impractical purchase for the average consumer. If cost is not the growing concern in today’s economy which prevents the consumer from considering this option; they may deny the technological advance due to battery storage capabilities and the inadequate infrastructure in place to refuel and provide for them.
Gasoline fueled cars produce a number of pollutants. The most damaging pollutants that come from gasoline fueled cars are particulate matter. Particulate matter is a sequence of organic materials and inorganic substances. It includes ingredients such as lint and minerals. Nitrogen dioxide, produced when fuel is burned at high temperatures, can cause damage to the lungs and cause chest pains. One might ask, “Why are Americans still driving gasoline cars?” knowing the damage that they are subject to cause. I personally maintain that the government should push people to p...
Over the last two centuries, humanity has become increasingly reliant on fossil fuels. Over that time, the consequences of constantly burning fossil fuels have accumulated into a threat to industrialized cities. The burning of fossil fuels causes acid rain to shower on cities and ecosystems around the world, tormenting their inhabitants. The increasingly deadly pollution caused by the burning of fossil fuels has caused the deaths of many people around the world by causing respiratory problems. Not only has the pollution worsened, but the supply of fossil fuels is not limitless – as humanity’s reliance increases the supply decreases, and that is all the more reason to break humanity’s reliance on fossil fuels. Fossil fuels should be replaced with cleaner alternatives because fossil fuels cause environmental hazards, are non-renewable, and are detrimental to human health.
The rising levels of atmospheric greenhouse gases (GHG) caused by the increased use of fossil fuels for energy services—notably transportation, heating, and the generation of electricity—is known to be one of the foremost drivers of climate change. The United States is responsible for one-fourth of the world’s total greenhouse gas emissions, representing only 5% of the world population and it becomes the world’s single largest emitter of atmospheric greenhouse gasses (EPA, 2011) . Since 1970, the U.S. share of net import of crude oil and consumption had been increased significantly and the majority of the imported liquid-based petroleum fuels were used for U.S. transportation sector (EIA, 2010). Today, the transportation is the second largest source of the end-use energy sector (CO2) emissions next to the electric power sector in the U.S. In 2008, the U.S. transportation sector becomes the significant contributor of CO2 emissions, which accounts for 95 percent of U.S. transportations GHG emissions and one-third of the total U.S. GHG emissions (EPA, 2011). In the same year, the U.S. light-duty transportation sector, including passenger cars and light-duty trucks consumed roughly about 60% of the total liquid-based petroleum fuel supplies (EIA, 2010). Due to the high-carbon intensive fossil fuel energy supply, the GHG emissions from light-duty vehicles accounted for about 40% of the total U.S. transportation’s GHG emissions (EIA, 2010).
The general petrol, more commonly known as gasoline, is the most readily available source of power for one's car today. This is because gasoline is generally cheap and readily available. Gasoline is defined by Poltcor as a "petroleum-derived liquid mixture consisting mostly of aliphatic hydrocarbons and enhanced with aromatic hydrocarbons toluene, benzene or iso-octane to increase octane ratings, primarily used as fuel in internal combustion engines" (Poltcor 3). Most automobiles rely on this type of gasoline today. At gas stations, the general grades available are 87, 89, and 93. Each of the numbers represents the quality of the gasoline, 87 being the lowest, usually named Regular and 93 being the highest, usually named Supreme. Generally, the gas prices in the U.S. are cheaper than overseas. However, the gas price has been rising over past few years because of some issues with the Middle East. Even with this problem in the Middle East increasing the gas price regularly, the U.S. maintains its ranking as one of the cheapest places to get petrol, or gasoline. Although gasoline is cheap, it is demanded of every person to have an automobile and since automobiles rely on gasoline, the gasoline distributors have the advantage that the public is willing to pay high prices for gasoline, if it's the cheapest around.
I wake up to my phone ringing non-stop, and my roommate, Max yelling “Wake up!” Although Max has a mild form of dementia, he usually sets a reminder to wake me up just to make sure I got to New Jersey in time. “Coming!” I yell. As I quickly grab my bags, I rush downstairs and prepare to leave. “Ryan, where are you going again?” Max says. “I’m going to New Jersey for a temporary job as an accountant.” “Why didn’t you tell me?” Max says, clearly getting angry. “I was packing yesterday and confirming that I had the job. I’m sorry.” “How is rent getting paid this month? The landlord still counts it as two people because your stuff is here.” Max asks. “I already have it taken care of. I really have to leave. I’ll see you this summer!” “No, R..” but the door slamming cut him off. As I got into the car, I remembered what Max did last time I cut him off. He had taken some of my stuff and burnt it into ashes. I brushed it off as if it wouldn’t happen again. Hopefully he wouldn’t overreact this time.

Over the last half a century there has been a more apparent impact on the environment due to the consumption of non-renewable resources, known as fossil fuels. The non-renewable resources included under the term fossil fuels are coal, petroleum, oil and natural gas. The use of fossil fuels has exponentially increased since the industrial revolution to the present day with each new wave of innovation. These fossil fuels main uses are to generate electricity, through the burning of coal and natural gas, and the refining of petroleum and oil for the production of fuels for transport. As helpful as these resources are they come with a cost to the environment, with the mining, refining and burning of fossil fuel is one of the largest emitters of greenhouse gases, (EPA). The use and misuse of the fuels has harmed our environment so greatly that it is now approaching a theoretical tipping point, at which the harm that is being caused will become irreversible. Along with many of these resources having already reached their peak, the United States began import oil 1970 due to its own production peaking (e), the reduction of the consumption of fossil fuels is now vital. Engineers play a role in reducing the consumption of fossil fuels through the creation of new technologies and processes, along with the updating and retrofitting of old systems.
