Hybrid automobiles are not the answer to the current fuel crisis in the United States. A common misconception with automobiles is that electric motors can somehow use less power to advance a vehicle along a road. This is not the case, as the laws of physics cannot be bent. An automobile needs a specific amount of power to travel along a road at a given speed, it does not matter what source is providing said power. These so called “green” automobiles, which are considered to be hybrids and electric cars, are actually less green than their internal combustion engine powered counterparts. With that said, they only seem so efficient because the matter in which they are tested does not accurately represent how a typical daily driver would drive. Auto manufacturers are neglecting to provide useful information about a hybrids performance, that is, the fuel economy of a hybrid as its battery is charging. It’s often the case that a battery need be recharged after 40 to 60 miles of driving, and that is where the fuel economy isn’t so peachy. The plug in solutions that manufacturers are pushing for by means of mass adoption, are only creating more pollution. The filthy air rising from powerplants’ smoke stacks is a byproduct of coal being burnt, which in turns provides electricity to charge up the batteries of a hybrid.
Sir Isaac Newton’s third law of motion states that, “If body A exerts a force on body B, then body B will exert an equal and opposite force back on A for the same period of time” (Wikipedia). In relation to driving an automobile, this means that in order for a vehicle to accelerate along a road, it has to overcome wind resistance and friction between the tires and pavement. Most importantly, both forces are related to th...

...the wall” is the far from eco friendly. The marketing and advertising teams at car companies are having a field day with creating this false image of a hybrid being economically viable, and it surely is not. Car companies cannot rewrite the laws of physics, which govern the world we live in. These audacious claims to great fuel economy and being eco friendly are misleading the uninformed public. A car’s fuel efficiency is directly related to its aerodynamic efficiency, not various sources that power it. If fuel efficiency is measured in miles per gallon, then clearly an electric motor, which does not directly use fuel, will produce greater statistics than its gasoline powered counterparts. Electric motors will inevitably replace the gas-powered car of today, but they should only do so when they can create less pollution, which they cannot at this point in time.
...about 300 miles (compared to the 70 miles of the first-generation EV1) . Environmentally, US air quality is worse than it was 20 years ago, and consumers have begun to notice. This will likely contribute to an increased demand for zero- and low-emissions vehicles. Legislation has once again been introduced providing tax incentives, rebates, and even free parking for purchasers of hybrid and electric vehicles. By 2005, over 200,000 hybrid vehicle rebates were cashed in the US, and this number continues to rise .
I bet you didn't know that the first cars made were all mostly electric. But as time passed gas powered cars became more popular through the years. There were few if any electric cars available as timed moved on. Everyone believed that gas powered vehicles were more convenient than the electric powered ones. I believe that gas powered vehicles are better because gas powered cars have more function ability. The range that electric vehicles have is poor compared to gas vehicles. Electric vehicles don't function very well when the weather is cold. You'll need to charge your car pretty much every night. You are only going to be able to go 80 mph. If you go up a big hill your range goes down. electric vehicles (rather ev's) do pollute but they don't pollute the same way that gas cars pollute.
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.
(Gilpin, 2014) According to Tesla, the efficiency of electric cars is three times that of the traditional gas engine as most energy is lost through the heating process.(Gilpin, 2014) There are two types of electric vehicles in production today, BEV’s and PHEV’s. BEV’s or Battery electric vehicles run solely on energy stored in a battery that is recharged at stations. These cars have an operating range of 60+ miles and take about 6-8 hours to recharge at a station.(Gilpin, 2014) Those who need to travel more than 60 miles in a day could face problems with this. Those that may need to travel much farther in a day would be wise to choose the PHEV’s or the plug-in hybrid electric vehicle. These vehicles run on both electricity and gasoline. They can run on electricity alone for up to 40 miles until it makes the switch to gasoline acting like a hybrid. This means that after they switch to their hybrid mode, they will use both electric and gasoline powered until they are charged again.(Gilpin, 2014) While in hybrid mode the PHEV’s can run up to 400+ miles before needing a recharge. (Gilpin, 2014) The relevance of electric cars is spiking. Especially in bigger cities that have air quality issues, the demand for transportation with limited emissions will be a huge
Driving has been around for just over 100 years, but the first thoughts of physics has been around since 400 BC (to be edited ). Driving safety implications have been discussed and improved over the decades as technology begins to leap ahead of its time. According to physician; Newton, there are three laws of motion that is now used in everyday life to try and help prevent deaths due to driving implications. The first law is “An object at rest will remain at rest unless acted upon on by an unbalanced force.” The object, or Car is in motion continues its motion with the same speed and in the same direction unless acted upon by an unbalanced force. The second law is “Acceleration is produced when a force acts on a mass.” While the third Law of Motion is : “ For every action there is an equal and opposite re-action.This means that for every force there is a reaction force that is equal in size, but opposite in direction.”
Most American cars are not hybrids or fuel-efficient, they are usually big SUV’s or trucks that get eighteen to ten miles per gallon. Most of Hondas, Toyotas, and Hyundai’s get around 20 to 30 miles per gallon, and hybrids get 50 miles per gallon. Peoples demand fuel-efficient cars because oil is i...
Environmental concerns have been raised from time to time because of the dependency on the gasoline-fueled engine as the chief auto powertrain technology. This has resulted in exposing many automobile users to unpredictable prices of fuel. These issues were, however, the reason for the inception of Tesla Motors so as to bring into existence another set of automotive which serves the similar purpose; but uses another form of energy that being electricity to drive them instead of the disadvantageous gasoline-powered engine. This invention was influenced by a number of factors in terms of their planning and performance (Hunger, 2010).
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
Hybrid cars use both gas and electric. The gasoline engine is the primary source of power, while the electric motor is used at low speeds. Emissions levels are reduced because the gasoline engine shuts off at low speeds. An additional benefit of the parallel configuration is that no outside source of electric power is required because the engine itself generates the required electricity. A Hybrid Electric Vehicle known as HEV have several advantages over traditional internal combustion engine (ICE) vehicles: Regenerative braking capability, which helps minimize the energy lost when driving. Engine is sized to average load, not peak load, which reduces the weight of the engine. Fuel efficiency is greatly increased, while emissions are greatly decreased. HEVs can be operated using alternative fuels; therefore they need not be depended on fossil fuels (http://www.ott.doe.gov/hev/what.html#hev). Another great thing about these machines is the mpg; on the average, a hybrid car gets anywhere from 55-70mpg on the hwy. This is what makes the car all worth having. Now all this sounds good, but there are some issues that must be addressed.
Today, people use their own personal vehicles to travel more than ever before. Personal transportation is no longer considered a luxury; it is now considered a necessity. The number of cars in the United States has been growing steadily since the 1970s. The number of miles traveled by cars has risen nearly 150 percent, yet the United States population has only grown roughly 40 percent during that time (hybridcars.com, Driving Trends). Although it may seem like we are advancing into the future, in reality, we are moving backwards from the effects these vehicles have on our bodies and the environment. The pollution produced by these vehicles has brought us to the day where we must find other modes of transportation that cause less harm to the world in which we live. Advances in technology have developed hybrid vehicles to try and slow down the amount of pollution. Driving a hybrid vehicle, instead of a conventional gas powered vehicle, can reduce the amount of pollution that affects our lives and the environment around us.
Electric cars are becoming increasingly more necessary, and have more advantages than disadvantages. Electric cars help to decrease the noise, pollution as they are much quieter. They do not emit any (or much less) carbon emission than petrol cars. Electric vehicles are the greenest mode of transport in the personal transportation industry. For each litre of fuel used in an engine produces more than 2.5kg of CO2. CO2 will be produced by an electric car but still a very little amount. It is also possible to use renewable power or a green energy supplier in the electric car. Thus it would lead to less polluted and safe working environment for all of us. However, safety is a big concern with using vehicles. The fluids in the batteries actually take impact better than a fully made gas car because it is not that flammable. Petrol cars and diesel cars are more flammable than electric cars so they are greater of taking impact in the event of an accident. I think that this is a very good reason because fewer people would get injured or hurt. This would save money because electricity is cheaper than gas and electric cars are easy to operate. Also is very ECO –friendly which mean that it is cheaper to run and have to pay very little road tax. In a pure electric vehicle there’s nothing combustible and have far fewer moving parts than you would find in a petrol or diesel car.
This research showed those hybrid electric vehicles are more worth full for the following reasons:
doubtful that electric cars will ever enjoy the range or performance advantages to which auto
Electric cars were recently introduced to the auto world. They are very fuel efficient while still having all the practicalities of a regular car. They are quiet and have zero emissions. They also are cheaper to maintain and cheaper to own then a gas powered car. Even though car enthusiasts dislike the idea of going fully electric, it is a very conscientious choice. Electric cars might seem like a useless form of transportation, but they offer features that help keep the Earth clean.
Vehicles in this day and time are nothing like what they used to be. Over half of the car manufacturers are now trying to build new cars and trucks to be as fuel efficient as they can be. Although hybrids conserve more gas than standard vehicles do, they use gas, also. Hybrids do not use as much gas as the ol...
