Internal combustion engine Essay
There is a big debate approximately the prox of the auto industry. The refreshing big topic is electric cars. Ads emphasize how much less pollution these cars put out, but the truth is that many people do not realize the downside of these cars. For instance, did you know that average bombardment terms for electric cars is between $18,000 and $20,000? Also, these cars produce signifi ground playactt more amounts of sulfur dioxide compared to traditional internal blaze engines, and what about the factories that burn billions of tons of coal everyday to produce electricity to give these cars?Yes, these cars do produce little carbon dioxide directly, but the main witnesser of pollution comes indirectly from the power plants that power these cars. Electric cars are not the best environmental solution in the bulky run be practise they still cause pollution while charging and producing them, there is no safe place to dispose of the batteries, and they are extremely expensive (Hog an). The first major issue with electric cars is that the member of manufacturing and charging these cars produces billions of tons of carbon dioxide emissions.The EPAs research shows that for an average size car, electricitys emissions are about three times high than the emissions of floatoline ( in spite of appearance temper Staff). Electric cars do not produce much pollution directly. Instead the pollution is rather created at the source of the energy, power plants. Pollution is caused when manufacturing and producing these cars too. In addition, greathearted amounts of pollution are produced while mining for the metals found in the new-sprung(prenominal) types of batteries. All of the mining machines and vehicles are powered from fossil fuels such as coal, gasoline, and diesel fuels.A great amount of energy is lost in the process of transmitting the electricity from the power source to your car. Also, electric cars fall out significantly higher amounts of sulfur dioxide into the air compared to internal-combustion engines. Sulfur dioxide is the main component that causes acid rain. erosive rain can cause damage to lakes, streams, forests, car paints, copper, stone, and other building materials. Acid rain soaks into the soil and roots of plants, and causes slowed growth, and loss of leaves or needles.In the Great Smoky Mountains, acid rain has actually killed one-hundred or more of the Frazier Fir and loss Spruce trees (U. S. Environmental Protection Agency). Furthermore, in the Northeastern United States. , such as in the Kesterson Reservoir in the San Joaquin Valley, acid rain caused hundreds of fish populations to pilot from lakes (Davis). Acid rain can contaminate our own drinking water without us even knowing it it tastes, and looks like regular water When sulfur dioxide is inhaled, it can cause damage to your heart and lungs, causing disorders such as bronchitis and asthma (National Parks Service).Additionally, barrage fire disposal is a k ey issue. The average life of this new type of batteries is twenty-five to thirty thousand miles before they pass on have to be replaced. If electric cars are going to be a thing of the future, there will become an excess of batteries in landfills and other disposal sites. Presently, landfills are not designed to handle the millions of batteries that would need to be disposed of if millions of people were ride electric cars. If these batteries are not properly disposed of, toxic chemicals could leak into the environment.Also, recycling these lithium-ion batteries doesnt appear to be in the future anywhere soon. The cost of collecting, organizing, and shipping these metals to a recycler far outweighs the value of the scrapped material, so for the time macrocosm, most of these metals will be thrown a commission in landfills and junkyards (Mitchell). Another obstacle with these materials being tossed in landfills is the possibility of corrosive chemicals leaking into streams, rivers , and lakes. The process of refining metals for these batteries also releases pollutants into the environment.Once the refiner gets what metal they need from the ore, they discard the other materials into the nearby ecosystems. When this happens, our drinking water could be contaminated, and it could also damage, or kill the wildlife in that area (Bacher). Lastly, these cars are extremely expensive. Because the batteries only last for about a hundred miles, this means you would have to charge them about three times for every full tank of gas that you would normally buy. Also, with this low charge capacity, it would be virtually impossible to take long trips.You would have to stop frequently to charge the battery, which takes about nine hours to completely charge. This would turn a normal two-hundred mile, four hour drive into at least(prenominal) a thirteen hour trip, assuming that you could find an open charging station Another reason that these cars are so expensive is that you h ave to replace the battery in your car about every twenty-five to thirty thousand miles. This is a very costly expense, especially since each new battery is about eighteen to twenty thousand dollarsThis is $80,000 for batteries alone if you drive 100,000 miles in your car The price of charging an electric car is less than what a full tank of gas would cost you, but you end up paying for it in the long run when you have to replace the battery. Electric cars are expensive from the start. The average sell price of most electric cars is in the thirty to forty thousand dollar range. Most middle class individuals cannot afford to pay this price for this new technology, which is why this will not be the best economical solution in the long run.These cost projections assume that both the car and the battery work correctly for the duration of their lives, but what if the battery breaks, or stops working, forcing you to replace it? The technology is new and underdeveloped, which means that t here might still be some problems or bugs that the designers havent had a chance to fix. Thats $20,000 right there that you would have to pay in addition to the purchase price. Thats shutdown to half of what you originally paid for the car Since these cars are less, there are fewer mechanics that are qualified to work or operate on them, so the price of operation will be very high.Electric cars were released around 2010, which means there hasnt even been enough time for a mechanic to get a four-year degree in operating on electric cars (Hogan). The problem with locomote pollution definitely needs to be intercommunicate and solved, but fully-electric cars are not the best solution. They are made out to be better than they actually are, and they definitely have major disadvantages. First of all, they will have to become a lot cheaper for people to be able to afford them. The general public cannot afford to pay $20,000 for a new battery every 30,000 miles.Designers also need to find a way to lengthen the range of these cars. With only a 100 mile range, it is just not practicable for most people. In addition, these cars still produce pollution, just not directly. All of the pollution is created indirectly, at coal-burning electricity power plants. Another unaddressed issue is that these cars emit large amounts of sulfur dioxide into the atmosphere, which is what combines with water to become acid rain. Lastly, there is no good place to dispose of batteries.If millions of people are going to be impetuous these cars, there will be tons of toxic batteries in landfills and disposal sites, which can cause harm to the wildlife, and the surrounding environment. If you accidentally miscalculate the charge left(a) in your car, you will be stuck. Unlike a gas-powered vehicle, you cannot simply fill up your car with a gas can. With electric cars, there is no way to replenish the energy in your car on the side of the road. The fully-electric car was a good idea, but in the long run, it is not the best answer.The automobile companies need to continue to improve internal combustion engines to decrease their carbon dioxide emissions.
