Global climate change is becoming an ever more relevant topic, and the reality of the issue is becoming more apparent. Support is growing to combat the effects, and one of the assumed ways is by driving eco-friendly vehicles such as the Toyota Prius or other hybrid cars. However, after researching some questions arise of just how eco-friendly these products are. One will explore the environmental effects of hybrid and all-electric vehicles. There are also economic impacts and social factors that will be addressed and they directly affect the production and consumption of these vehicles. First off, one must be aware of the different terms used when discussing the topic. Conventional vehicles are simply vehicles with an internal combustion engine, or an ICE, that powers the vehicle using gasoline or diesel. Standard gasoline-electric hybrids use both conventional power and batteries that store energy from regenerative braking or from the motor (Nice and Layton). There are also plug-in hybrids that use an all-electric power before switching over to a conventional power, thus using gasoline (Plug in hybrid). And stop-start or micro hybrids in which the gasoline engine shuts off only while the car idles (Gerbis). The history of hybrids and electric cars dates back to far before the realization of climate change and the environmental movement. The first experimental light-weight electric vehicles appeared in the USA, UK and the Netherlands in the mid-1830s. Later on, Thomas Edison joined forces, as he saw great opportunities for electric cars. He made substantial efforts to develop more efficient batteries. He developed the nickel-iron battery that could store 40% more energy per weight unit than the lead batteries (Høyer). The ... ... middle of paper ... ..." CarsDirect. 6 Mar. 2013. 07 Apr. 2014 .

By the early 1900’s, automobiles had become a common sight on the roads of the United States. Edison tried to create an electric battery that could power an electric car. Due to the abundant availability of gasoline, the electric car did not receive the response that Edison hoped for. However, the car battery was a huge success, and still plays a pivotal role in the automobile industry.

The beginning of hybrid cars goes back to the 20th century. The Paris Exposition of 1900 included the Lohner-Porsche Elektromobil which is the first ever hybrid car. The inventor of the Lohner-Porsche Elektromobil was a 23 year old engineer named Ferdinand Porsche. Porsche is known today for his Volkswagen cars and for the famous sport cars designed by his son. He created a vehicle that could travel 38 miles on electricity alone. Porsche partnered with Jacob Lohner who wanted to develop motorcars that had incorporated coaches. The gas-powered cars at that time were very noisy and difficult to start. Porsche created battery-powered electric motors and put them in the front-wheel hubs to produce a front-wheel drive car. He also added an internal combustion gasoline engine so the batteries in the car could be charged. Sadly, the Lohner-Porsche could only reach up to 35 miles an hour. The idea of hybrid cars decreased during the years of growth in the modern automobile industry. This period brought a national highway system in the United States and gasoline was inexpensive. The concerns with auto emissions brought back the idea of hybrid cars. C. Russell Feldman, one of the founders of Motorola, decided to explore the possibilities of hybrid cars again. He contacted an electrical engineer named Victor Wouk to see if a hybrid car could work in society. Wouk found out that the batteries in the hybrid cars did not have the energy to produce a lot of speed and range. In the 1960’s, Wouk combined the low-emissions benefit of an electric car with the power and range of a gasoline engine to create a hybrid car. To make his hybrid car ideas real, Victor Wouk and his partner Charles Rosen formed the company called the Petro-E...
...t of the electric car for the economic and practical benefits that would reinvigorate the country and make life easier for everyone. Upon revisiting the original question to this essay, the electric car is a worthy solution to our energy crisis and proves to be an economically responsible car. Its long-term cost savings outweighs easily improved flaws. However, in order to better understand the work done by scientists, research must be done specifically on the predecessors to the electric car and determine how those have stood the test of time. This will be done in order to help predict how the electric car will survive in the world. The future may always have a hint of uncertainty, but if scientists, governments, and drivers implement the new car with care, the goal of a smooth transition from fossil fuels to renewable energy sources can finally be achieved.
A hybrid vehicle is a vehicle that is powered by two or more power sources to move the vehicle (Lampton 2009). Among the types of power sources are electricity, petrol, and hydrogen gas. As of 2011, the world’s best selling hybrid, the Toyota Prius, on sale since 1997 has sold over 3 million units worldwide. Sales of other hybrids are also picking up. (Schwartz 2011)
(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
Imagine that you’re driving on an open highway in the middle of summer. All you see in front of you is asphalt for miles and miles. The windows are down and your favorite song comes on the radio. You’re behind the wheel of a Tesla Model S, the newest electric car that can go from zero to sixty miles per hour in 2.4 seconds. This will soon be the future of all motor vehicles. Electric cars are beginning to have colossal impacts on our society because of their energy efficiency, performance benefits, and the fact that they are less harmful to the environment. In the near future, electric cars will dominate the road and eventually the planet’s overall need for oil will decrease immensely.
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.

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...
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.
Environmentally Friendly Electric vehicles are today’s zero-emission vehicles. They have no tailpipes and emit no pollutants. Instead of gasoline from oil refineries, electric vehicles get their “fuel” from electric power stations. Although power plants using fossil fuels do have emissions, power plant emissions generated for electric vehicle use are typically much lower than emissions from the comparable use of gasoline-powered cars. For power plants using renewable energy sources like wind, solar and hydropower, no air pollution is created.
In this case study I will be discussing advantages and disadvantages of electric cars. Electric cars are cars that are powered by electricity. Electric vehicles are an important part of cutting emissions and reducing global warming. The battery of an electric car stores electrical energy. The electric motor is coupled to the wheels through gears; it converts 59-60% of electrical energy into the wheels. The battery runs the motor which allows the car to move. Electric cars are necessary as they will save money, because electricity is cheaper than gas. Also electric vehicles will help reduce global warming and pollution. However, some people say that electric cars still have environmental costs. The electricity used to recharge EV batteries has to come from somewhere in the world, and now, most electricity is generated by burning fossil fuels. Although electric vehicles are classified as green cars, purists will not appreciate the toxicity of the batteries.
