Background Conventional vehicles burn fossil fuels and emit exhaust fumes to the atmosphere. Not only have gasoline vehicles depleted natural resources, they also have caused severe environmental pollutions, especially in some populous nations such as China and India. [1] CO2 is the main contributor of the greenhouse effect. 97% of greenhouse emission is carbon dioxide. And in turn, road transportation has become the largest sector in producing carbon dioxide. [2] Because of the decreasing natural resources and the increasing environmental pollution, scientists focus more on new technologies that can help reduce those consequences. However, even though scientists hope hybrid cars could substitute traditional cars in order to reduce …show more content…
The most apparent difference is that hybrid cars have an internal combustion engine accompanied by an electric motor. When a car is moving at a low speed, the ICE (internal combustion engine) only provides power to the electric motor and the motor drives the entire vehicle. Thus, an electric motor helps reduce fuel consumption as well as car emission. Moreover, a smarter management of power called the regenerative braking system is introduced to hybrid vehicles. It converts kinetic energy to electrical energy during braking so that heat energy due to friction will not be wasted. The electrical energy can be used to charge the storage battery. [4] In addition, the aerodynamics and weight of the car body are carefully considered so the power supplied to drive the car can be lower than usual. Hybrid cars also have an adaptive strategy at traffic stops and idle periods. The engine shuts down so that exhaust will not accumulate at places such as traffic stops.
Apart from technical aspects, governments also take efforts to popularize hybrid cars for home use. In March 2013, the Chinese government extended the subsidy on electrical and hybrid cars for three more years. [3] And in certain traffic crowded cities such as Beijing and Hangzhou, electrical and hybrid cars have privileges on traffic restriction days. Nevertheless, customers still won 't buy hybrid cars because they do not believe that the technology is mature enough to replace traditional ICE cars with new energy
Electric vehicles and hybrid electric vehicles assist with emissions released into the air by traditional modes of transportation. Car emissions have been attributed to global warming and the deterioration of a healthy atmosphere. With more drivers purchasing electric and hybrid electric vehicles, we have been able to decrease these harmful emissions. By using electricity or a combination of electricity and gas, electric vehicles operate with fewer pollutants.
But with every great invention comes its downsides; the gas powered-automobile is no different. Focusing on environmental consequences, the typical gas-powered car releases pollutants
The emissions that is emitted into the atmosphere by the normal gas and deasil cars has a harmful effect on the air quality. According to Google, almost ninety percent of the air pollution is caused by normal cars. The country China has very bad air pollution due to lack of emission restrictions applied by their government. This causes the Chinese people to wear face masks so that the bad air does not affect their health. The Ford Fusion is literally a fusion between gas and electric car. Hybrid cars will decrease the gas emissions.in addition, there will be no emissions produced when the engine is running electrically. This will allow our generation to contribute toward the saving the planet and make a stop to global
Hybrid vehicles, which are environmentally friendly vehicles, which will replace fossil fueled car in the future but they have a limited range and long fueling time. As fossil fuel resources start to become limited and non-environmentally friendly, car manufacturers are looking to find ways to make hybrid vehicles the future of transportation. Hybrid vehicles are beneficial since they are efficient, reduce pollution, and cut global emission than the current hybrids models. As such, hybrid-electric vehicles can have real public benefits for both the environment and for energy security. Hybrid vehicles can help reduce smog pollution by ninety percent or more in comparison to the cleanest conventional vehicles today. Hybrids also give a rewarding tax insensitive in a way to get more people to buy and drive hybrid vehicles to help keep the environment clean. As for now, hybrids have their strengths and weaknesses that haven 't been perfected yet, but they keep on getting better each year.
I know that car makers are producing more electric and hybrids cars than ever. I had the opportunity to experience the popularized hybrid in action. About 5 years ago, my father purchased a Nissan Altima hybrid as gas prices were soaring higher than ever. This car really made an impression on me as it was one of the first cars I drove. I know the differences in functionality that hybrid cars have. Hybrids are equipped with engine shutoffs that activates when speed is reduced or stopped. In my opinion, this feature was frustrating and hard to adapt to. Besides their functionality, I also know
Though hybrid cars are a known technology, not many people know exactly what they are all about. Since many people don’t know exactly what they’re about, they then really have no interest in purchasing one. Hybrid cars are very different from gasoline cars. Gasoline cars run purely off just gasoline which pollutes the air. A hybrid car can run off gasoline and work as an electric car. Using both of these systems, gasoline powered and electric powered, will help decrease the pollution in the
Next the hybrid car functions on both gasoline and electricity. That means simply put the motors works by the gasoline powering the battery, which then powers the rest of the car. Since the gasoline motor doesn’t actually drive the car. The hybrid takes a smaller consumption of fuel at the pumps. In a sensible thought the hybrid car has rechargeable source of power on the go.
On the other hand, hybrid petrol-electric cars such as the Toyota Prius are becoming increasingly popular. Compared with new American cars of the same size, the Prius consumes roughly half as much petrol, and so releases half as much carbon dioxide. Moreover, its emissions of smog-forming pollutants, such as nitrogen oxides and hydrocarbon, are 90% lower. These hybrid cars cut emissions and improve fuel economy by coupling a conventional
Hybrid cars use both internal combustion engines as well as an electric motor. The electric motor requires no charging source, as electric cars do, as the movement during driving allows for kinetic energy to be produced which in turn, charges the electric motor. This process is known as Regenerative Braking.
Hybrid vehicles are continuously gaining popularity in the general public. With the growing societal concerns about green revolution and also achieving significant reduction in fuel consumption, hybrid vehicles are considered satisfactory in performance. They have become so popular that certain tax incentives have been offered by the government on hybrid vehicles. Due to their better performance compared with gas powered vehicles, we present the thesis of our paper as follows:
Hybrid cars are vehicles that have a combustion engine with an electric motor and battery pack. There are many types of hybrid vehicles and they are all different. As we know gas can be expensive at times. It is bad on our environment as it causes pollution. Hybrid vehicles is one way we have improved our economy and environment. It provides less emissions than regular vehicles and gasoline is just a backup, as these vehicles run off electricity as the main source. Earlier models have used lead-acid batteries, which were bad on the environment due to the high amounts of toxic lead. Hybrid vehicles have since then improved and now contain lithium ion batteries. Hybrid cars do have many positive aspects, but they are not completely safe toward the environment.
Hybrid cars have been hailed as an exciting green advancement for the vehicle and transport industry. Using dual electric and petrol engines, models such as the Prius
As indicated above, these three cars are not only great when it comes to mileage, but another advantage they enjoy is that they are also environmentally friendly. For example, the Prius produces 90 percent less harmful emissions than a traditional car (www.ineed2know.org, 2004), which is important to those individuals that are concerned about the environment. Even President Bush seemed to agree that alternative fuel vehicles needed to be further investigated when he endorsed the concept of alternative fuel vehicles and allocated more than a billion dollars toward the transition to hydrogen fuels (www.evrental.com, 2001). On the other hand, these types of cars are not a practical investment if cost and availability are issues. Not only is the price higher, but due to limited interest in hybrids by consumers at this time, there is only a small geographic area where hybrids are being rented. Most locations are situated in California, Arizona, and Washington; therefore, if ABC Rental Cars is looking for a new rental opportunity that could expand quickly, hybrid vehicles may not be the ideal choice.
Hybrid engines and electric and other forms of fuel are being tried the world over on account of multiple problems. It is not only for vehicles but also for the industries that use fossil fuels and chemicals for manufacture. The primary problem is the pollution of the air, water and the entire planet on account of fossil fuel use. Not all fossil fuel forms are harmful. For example CNG, compressed natural gas is less harmful. The use of fossil fuel has deadly repercussions on human, animal and plant health. In other words all life on the planet can be at jeopardy. The shocking truth is revealed as follows: John Vidal of the Guardian reported that millions die in Asia on account of vehicle pollution. According to the report he quoted, issued by a consortium of universities working in conjunction with the UN, most of the deaths in Asia are caused by air pollution and fifty two million people died by particle air pollution in 2010. (Vidal, 2012, p. 4)
While the popularity of hybrids and electric vehicles are on the rise, many people still drive a good- old fashioned gasoline car. Whereas driving a normal car will not be as environmentally friendly as the hybrid of electrics,
