Free Essay About Green Car

A green car also known as an environmental friendly car is a road vehicle that produces less harmful effects to the environment compared to conventional cars. It is referred to as a green car because it consumes less gas and therefore, less pollution on the environment. A green car can run on electricity only or a combination of electricity and hydrogen based fuel meaning reduced carbon emissions. This means carbon emissions on the environment will be at reduced levels and therefore, the amount of pollution and emissions on the environment will be at minimized levels. Moreover, the ozone layer is protected and this helps to protect all living things under the sun including human beings, plants and animals from ultra violet rays from the sun. Road transport is said to be the third largest source of carbon emissions in the air and if green cars are used, these emission will be reduced thus a clean environment. Also, green cars help in global warming as there will be no harmful emissions in the air to cause climate change.
In addition, using a green car provides a possibility of reducing dependency on foreign oil. Meaning, there will be no need of importing oil as the dependence on oil will cease. In addition, the amount of oil discovery passed its peak point 40 years ago and there is a possibility of oil shortage in the coming days. With the use of green cars, there will be no need to prepare for oil shortages or building large oil industries since they run on electricity and other alternative sources apart from fuel. Vehicle pollutants have been linked to pose risks on the human health for example lung cancer, respiratory and cardiopulmonary diseases. If green cars are used, many live can be saved.
There are challenges in green car use expansion. For example, the cost reduction and infrastructure. The infrastructure has to be recharged more often and this means a lot of money will be spent on infrastructure, Furthermore, its performance should be improved as the battery cost is reduced.
Carbon emissions are said to be the main cause of global warming and health risks to human being and this has forced many countries to consider strengthening carbon emissions regulations and this calls for the use of green cars. Forecasts reveals that, electric vehicles are making it on the market with their sales being estimated to 8 to 20 million by 2020 in order to comply with the rules of different governments while fuel cell electric vehicles are expected to be commercialized after 2020 meaning a free carbon emissions environment.
There are many different types of green cars on the market that function entirely or partly on alternative energy sources other than fossil fuels. Good examples are electric vehicles and fuel cell electric vehicle. An electric vehicle is driven by electricity energy and has no internal combustion engine operation. They are more efficient than fuel cell powered cars and have a better fuel economy as they do not use any fuel. Electric cars have no noise pollution and have a high green rating. Next, is the fuel cell electric vehicle that is driven by electricity from a chemical reaction of water and oxygen in a fuel cell. Fuel cell electric vehicles have no engines but use a battery and fuel cell.
Analysis of electric vehicles shows that their massive acceptance increased when the battery technology innovation occurs. Moreover, its initial expansion is by policy assistance. On the other hand, fuel cell electric vehicle’s acceptance is increased by depletion of resources and its initial expansion is when the hydrogen infrastructure is built.
The Hyundai-Kia Motors green car strategy is to improve the fuel economy by manufacturing more green cars in the market. Currently, four of their models are in operation and they are determined to develop more full green car line-up. A good example is their fuel cell car Mohave, which has a top global fuel system efficiency of 62 percent and the longest driving range. Saudi Arabia offers another solution through its Gaza 1, an electric car that was created by student at King Saud University and is to be produced by 2016 bases on a Mercedes G class platform.
Green car development in essential for national energy security, and it helps keep the environment clean from carbon emission. The use of a green car employs the use of clean renewable energy which produces less harmful emissions to the environment and having a high efficiency rate is a sufficient way to maintain a healthy and emission free environment.
