Are Hybrid Cars Becoming Safer or More Harmful to the Environment?

crossbreeding autos check a in truth special technology beca consumption they self-praise two situation sources a regular gasoline engine and an voltaic automobile labour personneled by a huge outpouring foreign inbornized political machines which go through unless regular gasoline engine. These comp whiznts gener tout ensemble(prenominal)y tame in tandem, though the exact mechanism varies dep sacking on the simple machine. When the car is at stop, the engine shuts off. While you push the accelerator, the electric cause turns on to get the car forward. When you need the situation much(prenominal) as for climbing a hill, the gas engine gets a boost from the electric take.The electric aim norm whollyy re ills itself by censoring the heat elan vital generated as you halt (Brown, 2008). mark cars similarly uphold to reduce the nub of smog arc because of less make watering of gasoline engine. This does non mean that intercrossed cars help the surround be cause they motionlessness have the affair of their batteries about being passing nocent to the environment. Nowadays, at that place argon much than than 5 million loanblend cars nearly the pieces only this means that there bequeath be in any case 5 million batteries from these crossbreed cars. What would happen in the near few years if these batteries end up in landfills? agree to environmental researchers, 90% of 1 million metric tons of lead which is produced e very year is use for vehicle batteries ( mark Battery Toxicity, 2006). These batteries still have issues in beat though they argon more environmentally hail-fellow than the standard batteries. Nickel may cause burncer in gentleman body because it is considered as a human carcinogen (Olberding, 2010). Therefore, legion(predicate) an(prenominal) battalion ar concerned about nickel mining as one variant of misuse of inwrought resources. According to the environmental Defense, there be iii main bat tery types such as lead, nickel, and lithium.The worst issue that painful to the environment is lead battery, followed by nickel, and lithium (Banas, 2010). By the way, the rechargeable crossbreeding cars clear force motive plants to produce excessive amounts of electrical dexterity therefore, bureau plant emissions can be just as harmful as exhaust pipe emissions. Running crossbreedingization cars on the street can also contri scarcee the amounts of greenhouse gases as same as racetrack normal vehicles because crossbreed system works effectively only on heavily congested streets ( mark Cars Negative Environmental Impact, 2007). veritable(a) though crisscross cars help the environment, they be still harmful to the environment collect to battery use, use of natural resources, and ineffective use of drive systems. II. Opposing Arguments A. Batteries The batteries in crossbreed cars give a better superior for the raise economy and environment that have been becoming to the next contemporaries of cars technology. They provide the electricity for electric motor hence, the motor uses less gasoline when they argon working in an urban area. Hybrid cars are able to provide more than 35% in force out economy (Facts on Hybrid Cars, 2012).The nickel metal hydride batteries have been victimisation in every crisscrossizingisation car since the first loan-blend car was produced. Both lead battery and nickel hydride batteries are rechargeable batteries, scarcely the environment clash of nickel is much lower than lead pungent which are used in customary vehicles. According to the article Nickel-Metal Hydride (2006), the nickel-Metal Hydride is a solid battery more efficacy can be disposed(p) for the amount of space. Density is an innate concern, as weight is a strong wall to aptitude.Hybrid cars are still sold in let down numbers therefore, the negative cause of crossbreedingisation batteries are non instant. B. instinctive resources Tod ays crossbredization cars are shown up by many benefits increasing discharge economy, and saving the fuel. thus far though it is true that hybrid cars can accomplish lots of gasoline, and we can get our tax back from them, the best thing of these benefits is the very less produced amount of gas emissions. Hybrid cars emit 80% less greenhouse gases than stately cars (Hybrid Cars Emissions Information, 2012).This translates to less airborne pollutants and a cleaner earth. The classic itemor of negative effects of vehicles on the environment is greenhouse gasses. As a result, most of greenhouse gasses are from human activities and cause the temperature in the air and ocean to rise (Hybrid Cars and Pollution, 2012). In fact, the temperatures are increasing. The changes have observed over the last few decades are mainly because of human activities, scarcely we cannot refuse that the important part of these changes is also a mirror of natural changeableness (Hybrid Cars and Pollu tion, 2012).Large metropolitan areas slightly the world are widely covered by this smog piece many millions of cars are concentrated. This smog is made of nitrogen oxides, hydrocarbons, and many evaporating native compounds. Hybrid cars produce a much lower these gases than conventional vehicles. However, the surface of the car can be a great different in emissions between the hybrid and conventional vehicles. According to Banas (2010), the average of compact hybrid cars emits 10% lower smog than their conventional counterparts.This means that the models of hybrid cars such as mid-size cars, mid-size sport-utility vehicles, and full-size SUVs help to reduce smog-producing gas emissions by 15%, 19% and 21%, respectively, more than their conventional counterparts. Hybrid cars are esteemed as being fuel efficient, and good for the environment. C. The efficiency of hybrid cars Nowadays, hybrid cars have been building to be more efficient than conventional cars as we known, small ca rs could be run more efficient than big cars.According to the article An Introduction to capacity (2006), one of the easiest ways to show efficiency is to get your amount of work with regard to how much null was taken in the initial place. The efficiency of conventional cars can be expound as how much the power of the engine is producing and divide by the amount of energy that was produced by gasoline when it was consuming. The energy of one gallon in gasoline is 115,000 British Thermal Units (Btu), and one Btu can increase the temperature of one cubic foot of air 55 degrees F (An Introduction to Efficiency, 2006).Therefore, if a hybrid cars engine had a c percent of efficiency about burning gasoline, then every oneness Btu worth of energy carried inside the gasoline would be used only to move the car onward. However, today, the best victimization of efficient gasoline engines is 30 to 35 percent. This is almost the same kind as the efficiency of a common light bulb, which use s the energy to produce light scarcely gains more heat. If you touch the dense fluorescent bulb by your hand, you can experience why it is so effective it produces abundance of light and less adenoidal heat.Conventional cars are comparatively inefficient at development the all amount of energy which stored in gasoline, and it is because of the engines mistake. Automatic infections can be infamously inefficient component in a cars power train. Conventional cars are inefficient using of gasoline. Both silky and the engines utilize use very little of the energy contained in all gallon of gas when they are burning because they are too heavy. So, hybrid cars can rip out the less using of gasoline than conventional cars as a result, they have designed to help increase the using amount of energy efficiency.Hybrid cars use electric motors to provide about portion of their driving force. Unlike gasoline engines, electric motors can be greater than 90 percent efficient at using electri c energy (An Introduction to Efficiency, 2006). As a result, if an electric motor consumed 100 kW/hrs of energy from the battery, 90 kW/hrs of energy would be turned into beneficial work. Some hybrid cars use manual transmissions, which they are much more efficient than automatic transmissions. As a result, hybrid cars do not have big electric motors and small conventional engines because electric motors are so much more efficient than conventional engines.This means that gasoline engines are the strongest point because they are completely juicyly-developed and presently cost of efficient energy alternation device from a manufacturing businesss standard system. However, big electric motors require huge energy storage like batteries. Big batteries are extremely expensive but that could be lower price if hybrid batteries are widespread to the worlds market, and being used by consumers as common as hybrid cars in today (An Introduction to Efficiency, 2006). The efficiency of hybrid ca rs is much more than conventional car due to the use of batteries and the transmission systems.On the early(a) hand, hybrid cars are not good for all aspects of the environment. III. Why They Are Wrong The chemical material, which uses in whether hybrid car batteries or conventional cars batteries, is toxicity. There are three main battery types that many hybrid car companies are using or considering for using in hybrid cars such as lead-acid, nickel-metal hydride (NiMH), and lithium-ion (Li-ion). However, lead-acid is the worst toxic of the three, and its very bad to the environment (Fuller, 2012 Banas, 2010 Olberding, 2010).Nickel is better than lead, but it still have a big problem because it is potentially carcinogenic and the mining attend to is considered hazardous (Fuller, 2012). We should be concerned about the environmental impacts of nickel mining, and decomposition reaction of the batteries. The types of power plants are the most serious cause of the environmental impa ct of hybrid cars that depend on where they are charged. California, for example, obtains 80% of electric power in its cities from pure sources, such as hydroelectric plants.Charging a plug-in hybrid vehicle in California cannot be good for the environment, since both the cars and the power plants produce harmful emissions (Banas, 2010). However, most states use coal burning power plants to generate electricity therefore, charging a plug-in hybrid vehicle produces power-plant emissions that can be just as harmful as tailpipe emissions, according to an Ohio State University lease (Banas, 2010). Not only hybrid cars but also the power plants are bad for the environment.An important issue is the dish of production as it could be a somber side of hybrid cars. One thing that many people dont usually think about consuming products is how much energy is expended to actually make them and move them around. For example, when people buy food from ample distance, it requires burning lots o f gasoline or diesel fuel to entrance that food. If more people bought local food, it could reduce wasting fuel in progress (Fuller, 2012). This can ensure that, the process takes a lot of natural resources and energy to build a car and that include hybrid cars too. both material that were used or parts of the car have to be make up and forged therefore, it uses a lot of amount of electricity and the natural resources to make it. The issue of hybrid cars has caught the interest of the media and the public in 2007, CNW Marketing Research, Inc. reported that Dust to Dust The Energy Cost of red-hot Vehicles from Concept to Disposal. The article claimed that it is necessary to create the calculation of a dollar value for all energy, build the operation of a vehicle, and there is the strike claim that the Toyota Prius costs more over the course of its lifetime than a Hummer H3 (Fuller, 2012).This made the Prius number one woods lead discomposed, since Toyota marketed hybrid cars an d accentuated fuel efficiency and economic friendly driving. After many media and internet newspapers started mentioning about the paper and disseminating the information, many publications speedily criticized the information from CNW for ambiguous information and lack of evidence. Most of the energy used by a vehicle came from its design and production, several other studies have found that 80 to 90 percent of a vehicles energy is used during operation in other words, when youre driving it (Gleick, 2007).The most important thing is it probably uses 13 % of their lifetime energy to be sustain a car. thus far though hybrid cars save the environment, but to begin with they be arrest a car, they have to pass many processes which are harmful to the environment. How hybrid car motor could be work effectively they depend on the driver behaviors and driving styles and geographic areas. If drivers drive very fast, busy driver that commute to and have to go to work every day on recollec tive distances of highway, this does not help anything about saving the fuel. The Hybrid car motors only work in the startup.However, It is going to be fine even if you want to burn more fuel at times as when you are driving on the highway, the gas can be used to recharge your battery system (All About Hybrid Cars, 2012). This is a big concern about hybrid cars. If the drivers drive very long distances, they will not get the benefit from their hybrid cars. If they drive in the city therefore, this process will be changed. Gasoline assisted hybrids are often started by the electric motor, so the stop or go of your commuting will largely depend on electric as opposed to gas.You can even expect to save about 15% in gas this way. However, you must be mindful that typically the electric motor will only run up to about 15-25mph before the gas engine give ups in (All About Hybrid Cars, 2012). If the drivers falling off the speed of their cars many times or rapidly, the gas will kick inat tentively. However, the function of electric motor will not be work better on the highway and up hills and down hills areas. The electric motor typically assists in startup, but will kick in areas of high speed or when the engine needs run on the very fast speed (All About Hybrid Cars, 2012).Hybrid cars could be worked effectively in the urban area or city commuter. IV. Arguments for hybrid cars A. Batteries toxicity When these hybrid car batteries are dead, where will they end up? When batteries are disposed of improperly these metals can be detrimental to the environment. check and nickel sitting in a landfill can cause befoulment to the groundwater causing acid rain and making it unsafe for drinking and also harmful to plant life (Bova, Goodwin, Marrs, Oliva, 2010). The effects of these toxicity batteries are human carcinogen, causing many diseases and reathing problem in humans. According to a subject area done by Environmental Defense, the more popular lithium-ion batteries found in most hybrids and electric vehicles are not as toxic as their lead and nickel counterparts, but still have negative effects on the environment (Bova, Marrs, Goodwin, Oliva, 2010). The big car companies such as cosmopolitan Motors and Toyota claim that hybrid car batteries can be 100% utile but the processes are too expensive. However, many companies are promoting the recycling of hybrid car batteries by motivating their customers.For example Toyota offers a $200 stipend and even provides a number to call printed on the battery itself. stock-still with these incentives there is no way to guarantee that owners will in fact recycle the batteries leaving the window open for batteries to end up in the landfills causing further destruction of the environment (Bova, Goodwin, Marrs, Oliva, 2010). However, nowadays the numbers of hybrid cars around the world is still lower than conventional cars. If the number of hybrid cars is increasing over the year, landfills all around the w orld will be full of toxicity batteries, corrosive materials, and carcinogenicB. Overconsumption of natural resources Nowadays, the most essential problems in the world are global warming and rising oil prices therefore, we should concern about the alternative energy, and especially friendly environment, which focus on hybrid car designs. The most accessible of these designs was the hybrid car, with working models already on the road. With their highly fuel efficient design, they deliver much of what they promise, but the hybrid picture is not entirely problem free (Hybrid Cars Negative Environmental Impact, 2007).Many hybrid car companies did a big problem because before they were going to be batteries and electric motors, they are very rare elements and dont exist that much around the world, which go a long way to explaining their expense. Most of these elements currently come from China, and the supply as it exists today is not expected to last more than several years under even the most generous estimates (Hybrid Cars Negative Environmental Impact, 2007). Many efforts are going to consider a new resource for these rare elements, but they will not be produced that much until they are becoming less and cause a shortage.Hybrid cars are complex vehicles and full of new technologies and high end technology therefore, these make hybrid cars to be hard to build which use lots of energy to build hybrid cars. Some hybrids can charge their batteries from mains power, and this could be generated by a dirty technologies such as coal fired power stations or nuclear power (Hybrid Cars Negative Environmental Impact, 2007). This is the fact about hybrid cars on the market, and it means that different types of hybrid cars can use different types of power to produce electricity which affects the environment. C.Inefficiency of hybrid cars Once hybrid cars are build and spreading everywhere on the road, the important thing that will come up on drivers mind is, they are doi ng good for the environment. This is the fact because hybrid cars use less fuel than conventional cars but it depends on how they drive. think up that a hybrid will probably never match the listed fuel efficiency because of the way the efficiency test is done, and because unless you only ever drive on heavily congested streets you wont be utilizing the hybrid system effectively (Hybrid Cars Negative Environmental Impact, 2007).If hybrid cars are running on the high way, there will be only the gasolines engines that are working on the time and neglecting the effective of hybrid system. Even though hybrid cars regard as green environmental cars, hybrid cars with an internal combustion engine will still emit smog. Catalytic converters handle most of the contamination, but theres still that good old greenhouse gas, carbon dioxide. Even hybrids pump this out, they just pump lower amounts of it, and mostly because most hybrids have engines that stop when the vehicle comes to a halt (Hybr id Cars Negative Environmental Impact, 2007).However, driving hybrid cars is not saving the world but you have just been retarding your harmful to the environment. V. Conclusion Hybrid cars are not good for the environment at all. They are still bad to the environment. Even though hybrid car batteries are good for the environment good now but what if they end up in the landfills when they are expire in the future therefore, our landfills will be full of toxicity. Many people think that hybrid cars are green environmental cars but they didnt think about the process of building hybrid cars.Every process of making hybrid cars is bad for the environment due to the use of natural resources. However, when hybrid cars are shown up on the road, hybrid car motors sometimes cannot work effectively because they are working well only on the congested areas. The effective of hybrid car motors are also due to the behavior of drivers because if they always step on the accelerator, they will nega te the efficiency on hybrid system. The price difference of a hybrid power not always benefit the gas deductions. Depending on how you drive, hybrids might not always be a match for your lifestyle.There is always the issue of the toxicity of the battery, even though they are not as harmful as standard car batteries to the environment. It is also beneficial to keep in mind that todays EPA standards are slightly outdated. They will ordinarily be on the lower end of what EPA estimates are, due to differing factors such as driver lifestyle, location, and the type of car it is. I strongly believe that hybrid cars are not that save the environment at all but they have just slowed down the impact on the environmental therefore, do your researches before you buy a hybrid car.
