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).
Over the next few decades, it is projected that the demand for liquid-based petroleum fuels required for light-duty transportation is to be expected to grow rapidly (EIA, 2010). Due to the increase in consumption of gasoline for combustion of internal engines, there could be increase in the G...

The 1996 documentary Who Killed the Electric Car? explores the factors behind the demise of General Motors’ EV1, the popular and elusive electric car of the early 1990’s. The EVI was popular with the public, and it was clean, fast and efficient. This video sets out to solve what is effectively a murder mystery – the plug was pulled on the EV1 in 2002 after only 1,000 of these cars had been produced by GM, most of which were subsequently destroyed by the company in a secret location in the Arizona desert.
“World consumption has been on a steady rise for decades and neared 94 million barrels a day in 2014. Estimates from the U.S. Energy Information Administration sees the number increasing by another million barrels a day by the end of next year” NewsMax. "That’s the equivalent of draining an Olympic-size swimming pool every 15 seconds" Tertzakian. 57% of all the oil that is used in the U.S. is imported and 70% of all the oil used in the U.S. is used for transportation according to American Energy Independence. “The U.S. transportation sector consumes about 220 billion gallons of liquid hydrocarbon fuel per year” Energy Information Center. The energy used by the “transportation sector” is usually for passenger travel and for moving freights. Passenger
The tradeoffs of using gasoline for cars are large emission of carbon dioxide and required large amount of chemical t...
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).

Electric Cars Buying a car is usually going to be the first big purchase a person will make in their life. It is actually considered the second biggest purchase, right behind buying a house. Cars can now do things like park themselves and even drive themselves. Electric cars are also a thing that is getting a lot of attention, and studies show that they will be what dominate our streets and highways in the near future. Many people turn to electric cars because they are very efficient in our pockets.
...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.
Electricity production causes approximately 67 percent of 2014 greenhouse emissions, transportation contributes about 26 percent, industry is responsible for about 21 percent, commercial and residential generates about 12 percent, agriculture produces 9 percent, and land use and forestry yielded 11 percent. (EPA Environmental Protection Agency,
In addition to the fact that solar, wind, and hydro power are local resources, they are also emission free resources. Emissions and pollution are a key concern with traditional power sources. The coal-fired plants that dominate U.S. energy production also produce more emissions than any other energy source. “Em...

The emission of green house gasses due to human activity contributes the most in increasing global warming. Today, fossil fuels are used as a source of energy for transportation, electricity, industrial process and to increase human comfort in this era. Over the last decade humans have created mass amount of industries. These industries have been burning fossil fuels such as coal, which release carbon dioxide and carbon monoxide; carbon dioxide absorbs heat that raises the temperature of the earth. More than 80% of carbon dioxide comes from tr...
Environmentally Friendly Electric vehicles are today’s zero-emission vehicles. They have no tailpipes and emit no pollutants. Instead of gasoline from oil refineries, electric vehicles get their “fuel” from electric power stations. Although power plants using fossil fuels do have emissions, power plant emissions generated for electric vehicle use are typically much lower than emissions from the comparable use of gasoline-powered cars. For power plants using renewable energy sources like wind, solar and hydropower, no air pollution is created.
The seriousness of global warming effects both the environment and the people living in it. The question is how do Americans effect the environment and what can we do to fix it? Americans everyday use automobiles as a form of transportation, and although it may seem harmless, the use of these cars are proving to be detrimental in the end. Author Margaret Kriz (2006) states that, “the vast majority of scientists who study Earth's climate agree that the planet is warming, and they blame the greenhouse gases that accumulate in the a...
There is no doubt that electric cars are the most appealing from of transportation in the world. They provide two of the most important key points of good transportation: reliable and efficient. They are reliable due to their simplicity of their power trains and the advancement of technology they have. They are efficient because they don't use any gasoline and because their motors can pass the zero-emission standard. Even though they may seem like a boring form of transportation, they offer good features that help keep the Earth's air clean and they help reduce pollution.
