Matt Frey Ms. deGozzaldi 8th Grade 6/21/17 Hybrids Hurting the Earth? Hybrids are deservingly known for their fuel economy, a 2016 Prius c can get up to 50 MPG (FuelEconomy.gov, US Department of Energy). They are also known for being kind to the environment: Toyota advertises the Prius c, as seen below, as an “everyday eco fun sized for the city” on their website (Toyota, toyota.com/priusc). In Kia’s Super Bowl LI commercial for their new hybrid crossover, the Niro, they use the tagline: “it’s hard to be an eco warrior, but it’s easy to drive like one.” Hybrid owners agree with this; they can be seen driving around with proud smiles on their faces, knowing that they are saving the earth. But they have likely done little research, because …show more content…
There is an explosion just as the piston is at its highest point, and the volume of the chamber is its lowest. This phase is called combustion. The force of this explosion pushes the piston down, and then up again as a second valve opens, pushing the exhaust out and into the air. This final phase is called exhaust. As the piston moves down again, the cycle repeats. Now, in a hybrid car, there is a battery assisting, so that the cylinders have to do less work, and consequently use less fuel. A Prius has only 84 horsepower without its electric battery, and wouldn’t even be able to start! (Regular Car Reviews, Youtube) But this battery isn’t all good, which brings us to the first problem with these hybrid cars. The batteries are made from metals like cobalt, lithium, and nickel. The nickel is mined at a damaging mine in Ontario (Demorro, NCPA 2007) and some of the other metals can come from unstable countries around the world, says Anderson in “5 Reasons Not to Buy a Hybrid.” He also mentions that increasing dependence on, well, undependable countries couldn’t help us. Not to mention, all of these materials are destructive to the environment to mine. Another problem is the emissions of harmful substances besides just exhaust. “Nickel-hydride batteries are responsible for higher sulfur oxide emissions, roughly 22 pounds (10 kilograms) per hybrid compared with 2.2 pounds (about 1 kilogram) for a conventional vehicle” (HowStuffWorks:
Gasoline powered vehicles are better! No, hybrids are better! Have you heard these two points-of-view? This last election, the question of energy was a part of both party’s platforms. They talked about wind and solar versus coal and oil, and gasoline versus hybrid vehicles. So here we are, the election is over, but the battle between a gasoline powered vehicles versus a hybrid continues. You might know someone who owns a hybrid car. My uncle bought one in 2006 and for him it works great, but he usually just travels back and forth to work. However, my uncle’s needs are not the same as my dad who is a contractor. In the end, you need to weigh the pros and cons before deciding on which vehicle is best for you. After much research,
Are hybrid vehicles really that much better than normal gasoline vehicles? There are known pros and cons of having hybrid vehicles. Climate change is a huge issue in society and continues to grow as a worldwide issue. Hybrid cars use both a battery powered engine as well as a gas powered engine, it’s a very complex system for more things to go wrong in. Also, it has a special system for storing brake energy in an on board battery.
One of these factors is water consumption. Water is a precious resource for all of humanity, people need it to survive, and with water shortages all over the world its a resource people should not misuse. Batteries overtime dissipates the water that is in them due to heat and evaporation. So a consumer, after a period of time, will need to fill the batteries with water, just like maintenance of a standard non-electric vehicle. Furthermore experts have stated, “A new study by University of Texas researchers found that switching cars from gasoline to all-electric or plug-in hybrid would cause three times more water usage than what oil refineries would normally consume.” Which means, not only do you have to fill it up to cool the batteries, but
Hybrid cars are built on the advantages of both combustion engine cars and battery-powered electric motor cars, and the hybrid cars will be an alternative to combustion engine cars until next step technologies such as fully electric vehicles or fuel-cell powered vehicles will take over. This article supports the ideas shown in the main source through hybrid vehicle technology.
Ronnie Steele’s case analysis creates strong argument for both biofuels and lithium polymer batteries to be used in order to increase engine performance. For each he presented pro’s and con’s that allowed the reader to develop an informed opinion.
Although hybrid vehicles are very beneficial to our environment, some would argue otherwise. Some people would argue that hybrid cars are not good for the environment, and that for people to begin to buy them to end pollution would be useless. Others would argue that hybrid vehicles are not really all that green, and don’t help the environment as much as they are said to. They would argue that by simply buying a clean diesel vehicle, such as the Volkswagen Jetti TDI, would be a better option. These people would be wrong, however, because even though the clean diesel vehicles are cheaper and less smelly, they still give off a tremendous amount of gas emissions that hybrid vehicles do not. Thus, making hybrid vehicles more green and traditional
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 have always wondered what Hybrid cars were all about. Especially because over the past couple of years gas prices have been at record highs. I knew that there were such things as electric cars but until this last year or so I have only seen the wealthy be able to afford to drive them. And from what I had heard about Hybrid cars was that they were over priced, small, and not so attractive cars. No wonder nobody owns them. Now I am starting to see them more often and they aren't as bad as everyone had said.
Abstract- Today’s environmental situation is continuing to spiral downwards; the ozone layer is receding, habitats being destroyed, and the air is being polluted. Scientists of every nation are researching ways to solve this problem. Due to automobiles sizeable contribution to the environmental crisis, studies are focusing on ways to reduce the harmful emissions caused by the internal combustion engines. Hybrid vehicles offer an alternative to powerful gas engines by providing the car with a secondary propulsion source powered by a strong battery. With this secondary power, car manufactures can reduce the size of the internal combustion engine, which accordingly reduces emissions and raises the vehicles miles
The emissions of a hybrid vehicle are suppose to be low and better for the environment than a normal gas vehicle, but the pollution created by
The Toyota Prius leads the market in hybrid fuel efficiency, according to FuelEconomy.org, because the model gets almost about 50 MPG no matter where you drive or live.[2] Other hybrid cars also get mileage ratings of more than 40 MPG. Hybrid cars can achieve these astonishing efficiency ratings while enjoying the full range of torque, acc acceleration and driving-range
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
The main component of a car would be the power that actually puts the car in motion. To be solely dependent on one power source is not a very good idea as it is not eco-friendly and at the same time not suitable. By 2040, half of all the new cars being sold will be hybrids, according to Exxon Mobile. Hybrid Cars are the cars that uses more than one power sources to run the car. It is usually referred to the Hybrid Electric Vehicles (HEVs) which has both the internal combustion engine and electric motors that generates power. One of the main problem with these hybrid cars is that their batteries are extremely heavy and takes up a large amount of space in the car. The concept of Hybrid cars can be a good thing to the environment, but definitely not for the car manufacturer or the customer. Hybrid cars have a convincing amount of weight due to their batteries, even with the existence of lithium-ion batteries. As a solution, Energy Storing Body Panels are used.
Energy is the lifeblood of modern society, but the major energy supplies are fossil-fuel generation, which leads to air-pollution and environmental issues. Then, there is an increasing need to develop renewable energy to balance the demand and supply. Electric vehicles and hybrid electric vehicles will be the effective method to decrease fossil-fuel usage and rechargeable batteries are one of the main strategies to power these vehicles. [tarascon]
People buy hybrid or electric cars because they either want to save money on gas or they want to be able to help the environment with their vehicles. One of the most popular hybrid vehicles in the United States is the Toyota Prius, which, compared to a normal gas powered car, has great mileage and reduced fuel emissions. The popularity of the Tesla Model S--a fully electrically powered car--has recently skyrocketed due to the increase in gas prices. Hybrid technology powered cars, such as the Toyota Prius, are better for the environment than fully electric powered vehicles, such as Tesla’s Model S, because of the emissions created by the electricity that powers the vehicle.
