Air pollution is a major contributor to the deteriorated state of the environment. Vehicle combustion systems that run on fossil fuels emit particulates such as carbon dioxide to the atmosphere thereby polluting it. This has increased the percentage of carbon dioxide in the atmosphere which in turn has raised the earth’s temperature. This fact favors development for global warming because of ozone layer destruction. The ozone layer protects human beings and all living things in the earth from the harmful effect of ultra violet rays emitted by the sun. Environmentalists are calling for the manufacture of eco friendly vehicles as a measure of controlling this phenomenon.

The adverse effect of global warming has resulted to the introduction of eco friendly campaigns and green technology. Today there are various eco friendly cars in the market which use other fuels other than fossil fuels such as hybrid, bio-diesel, ethanol, electricity, natural gas and fuel cells. However, the following question arises which type is most efficient in conserving the environment and financial costs?

The efficiency and financial cost of eco friendly vehicles depends on the location where you are situated. For example if living in the US, it is advisable to purchase an eco friendly vehicle that uses ethanol. In US ethanol is readily available because it is a high potential area for corn, wheat and barley production, plants used to manufacture ethanol.

Natural gas is cheap and clean thereby extending the shelf life of your car engine. However, it is available in minimal amounts because it is derived from natural resources whose existence is under a risk of extinction. This explains why there are very few fueling stations that provide natural gas fuel. Therefore, this type of fuel is mainly used by drivers covering short distances.

Bio-diesel is manufactured from plants therefore comprises of vegetable oil constituents. People living in year-round temperature climates are best suited to use this type of fuel. This is because vegetable oil solidifies in cold temperatures thus affecting the mobility of the vehicle. Most people prefer to purchase vehicles that use biodiesel because of their diversity. Bio-diesel engines are designed to also accommodate use of diesel thus availing a wide selection of eco friendly cars to choose from unlike when using natural gas where you have a limited choice.

Hybrid vehicles are designed to use two types of power sources, a battery charged by electric motors and petrol. The battery is used when the vehicle is travelling at low speeds or when in a traffic jam. Petrol is used when the vehicle is travelling at high speeds. This fact increases the efficiency of the combustion engine as it operates at its optimum speeds. Furthermore, the combination of an internal combustion engine and battery power reduces the overall carbon dioxide emission. This is because electric motors do not release gases thus non escapes into the atmosphere. On the other hand electricity and fuel cell eco friendly cars demand for higher technological advancement therefore, their use becomes unrealistic to most people.
