Global warming is caused by greenhouse gases such as carbon dioxide (CO2). Greenhouse gases can destroy Ozone air layer that shields dangerous waves from sunlight like ultraviolet wave. The result of that hazardous waves able to down to the ground too much and the earth get higher temperature. There are many organizations are trying to create technologies that can reduce the greenhouse gases such as the Nissan automobile. Nissan Leaf is a model of electric cars that Nissan created for decreasing releasing amount of greenhouse gases. Electric cars use electricity for transportation, so when drivers are driving the cars on the road, they will not release any carbon dioxide. However, the electricity that electric cars use for recharging comes …show more content…
Depends on Where You Plug In”, Paul Stenquist (2012) illustrates that electric cars can release greenhouse gases or can not because it depends on how the electricity that is used to recharge the cars was generated from. According to Stenquist (2012) if the electric cars are recharged by the electricity that is generated from renewable energy like nuclear and solar power, the cars would have zero for carbon footprint. Also the electricity that is generated from natural gas that would produce carbon less than coal. Carbon footprint is the total amount of gas carbon dioxide, one of the greenhouse gases, that the cars release or spend. The author also gives an example to show how charging electric cars at Denver and California are different in amount of carbon footprints. Reports from EPA and U.C.S. are used by Stenquist (2012) to support that the carbon footprints that the cars made are different depend on the sources of electricity that recharge the cars. However, the chief excusive of Nissan at that time declared that it does not matter what is the electricity that recharge the cars generated from, electric cars are still better in the way that can reduce emission than the best of gasoline car model can
Fumes from the car play a huge part in this catastrophe. While the temperature gradually increases, more heat is allowed into our atmosphere, which makes Earth’s temperature rise. To solve this predicament, we can stop using gasoline and diesel powered vehicles. Electric cars can eliminate this huge issue with our planet and its climate.
Firstly, global warming is said to be caused by the high levels of carbon dioxide released into the atmosphere by humans. Smoke produced by factories, vehicular exhaust, and the burning of fossil fuels such as coal in power plants are the primary sources of carbon dioxide. The theory is that carbon dioxide being released into the Earth's atmosphere is steadily building up because it cannot escape into space. The theory as to why the carbon dioxide in the atmosphere actually causes the Earth's average temperature to rise is outlined as follows:
Nissan was the first company to introduce a 100 percent electric car that produces zero emission and they had great hopes for this vehicle (“Nissan Product Information”). According to Michael Strong, the company believed that this car would be the future of transportation and that it would soon be responsible for 10 percent of all new vehicle sales. However, after 3 years on the market, Nissan’s CEO Ghosn admitted that the Nissan Leaf is only accountable for 4...
The substantial increase in the demand for EV’s came just in time as we are slowly but surely running out of oil. Some estimate that by the year 2040, 35 percent of all vehicles will be electric (Sullins, 2017). An article from the U.S. Department of Energy stated that “Electric vehicles hold a lot of potential for helping the U.S. create a more sustainable future. If the U.S. transitioned all the light-duty vehicles to hybrids or plug-in electric vehicles, we could reduce our dependence on foreign oil by 30-60 percent, while lowering the carbon pollution from the transportation sector by as much as 20 percent (energy.gov, 2014). It’s obvious that gas-powered vehicles have harmed our planet with their emissions. Although EV’s cannot reverse that damage that has been done, they can eliminate, or at least slow down, the inevitable demise that our planet is headed towards. Along with the beneficial environmental factors that correspond with electric cars, there are also beneficial financial factors. The average American spends about $2,000 on gas annually. In the future, charging stations will charge roughly $12.00 for a full charge, which is about 300 miles. This means that the average American will save about $1,400 per year on these specific car
Global Warming is a phenomenon in which the temperature on the Earth increases. Over history we see natural stages in our Earth’s climate between warm and cold periods because of increased Carbon Dioxide. These stages are usually cyclic but temperatures are rising faster than ever before (Pipkin). Ancient ice cores dating back 800,000 years show a steady level of greenhouse gasses (Scambos). Proving this point Ted Scambos states: “The dramatic rise in the gasses seen in the past few decades- from 315 parts per billion in 1958 to 388 parts per million for carbon dioxide. . . "(37). Greenhouse gasses are emitted from the burning of fossil fuels (Carbon Dioxide, Methane, and Nitrogen Oxides). These gasses create a barrier that traps the incoming solar radiation (Insolation) and reheats the earth. Carbon Dioxide is the most abundant of the gasses but not nearly as powerful as Methane. For instance, "Methane in the atmosphere warms the Earth over 20 times more per molecule than carbon dioxide does than after a decade or two, it oxidizes into Carbon Dioxide and keep...
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.
It seems like more and more people are purchasing electric cars everyday, infact, it is very likely that you yourself have or know someone who has an electric vehicle. When asked why these people decided to make the purchase, the response would more than likely be that they wanted a car that was better for the environment. However, various research studies have proven that electric vehicles are not that much better for the environment, in fact they worsen the environment. For example, according to a new study published by the National Bureau of Economic Research, electric vehicles are worse for the environment per mile than comparable gasoline-powered vehicles (Russel, J. 2015). Another factor that harms our environment is the use of coal, of which electric cars produce 3.6 times more soot and smog deaths than gas. That is due to the pollution made in generating the electricity, according to a separate study published in December by the Carnegie Institution for Science (Zolfagharifard, E. 2015).
In conclusion, global warming is an increase of the Earth’s surface temperature and the Earth’s lower atmosphere. Atmospheric greenhouse gases (water vapor, carbon dioxide, and other gases) trap outgoing energy, and retain heat like the glass panels in a greenhouse. Many people believe that humans are causing the problem with emissions from things such as cars and trucks. Others say that the warming is just part of a trend and that the world goes through warm and cold periods. If the planet continues to warm, there could be many harmful side effects.
In talking about global warming, we need to learn what causes the greenhouse effect. Rays from the sun are taken up and absorbed by water vapor that is natural in the atmosphere. The United States emits the largest man made greenhouse gases in the world. As Americans we must realize the responsibility to reduce the emissions. (Gore, Albert) Water Vapor is eighty percent of greenhouse warming. The last twenty percent results from other gases that are in very little amounts. A huge absorber of the sun’s heat rays is carbon dioxide. Us as humans release a lot of carbon dioxide. When fossil fuels are burned, they release big amounts of carbon dioxide. Carbon dioxide is on the increase in our atmosphere due to car emissions. Approximately eighty percent of CO2 increases because of man’s use of fossil fuels. When there is more carbon dioxide in our atmosphere the more sun rays are absorbed. In result to this happening this will cause the earth and the earths atmosphere to warm. When the earth is warming, water temperatures will start to get warmer. Oceans and lakes will get warmer in result f...
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.
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:
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.
Global warming is the rise in the earth’s average atmospheric temperature. When sunlight heats the ground surface, it releases most of the solar energy it has absorbed as infrared radiation. Then what is known as the “greenhouse effect” occurs, this is where the gases in the atmosphere absorb the re-radiated infrared radiation and the escape of these gases being released into space is prevented. As long as the composition of greenhouse gases in the atmosphere does not change, the heat in the atmosphere will remain constant by releasing the contained heat into space. It has been noted that greenhouse gases, such as carbon dioxide, water vapor, and methane, have been increasing steadily since the early 90’s, and around this time the average global
There have been some steps toward conserving gas. Hybrid cars are becoming more and more popular among Americans and as well as other consumers. These cars will use less gas to get more mileage. Honda, is taking .steps toward lowering harmful gasses into the atmosphere by introducing these futuristic cars to the American public The main purpose of these cars is to reduce the dependency on gas for automobiles. As cheap college students, we all know how expensive gas is today, wouldn?t you rather save all the money you spend on gas and use it for other things like beer, clothes or other recreational purposes. The effects of global warming will have a lasting impact on the entire world. All people in all nations will experience unfortunate outcomes if something isn?t done soon.
Global warming is an increase in average global temperatures. This will lead to rising temperatures of the oceans and the earth’s surface. Coal is a main contributor to global warming because so much electricity is produced from coal-burning power plants. According to the book Global Warming by Peggy Parks, “In the United States, more than 50 percent of all electrical plants use coal, which also provides power for about 40 percent of the total electricity generated throughout the world” (43). Global warming is also caused because of deforestation and the burning of fossil fuels. Many people say that global warming is natural; however, people speed up the process. Global Warming needs to be taken serious because as the temperature rises, it causes melting of polar ice caps, a rise in sea levels or unnatural patters of precipitation which can result in floods. This can also have an effect on wildlife such as the food chain. Many species have been dying of starvation and many have to move to different places due to the temperature changes. Possible solutions to Global Warming is for people to switch to LED light bulbs as it gives the same light and uses less electricity, wash clothes in cold water, buy less products, and to spread the
