A comprehensive study on green technologies used in the vehicle

To ensure the safety of environment a major challenge to the vehicle manufacturer is the emission rate of vehicle. Emission of environment polluting particles especially CO
2
from conventional vehicles is a direct threat to the environment. As global vehicle market are expanding day by day so this high rate of emission is already a nightmare to the environment specialist. That's why some of green technologies are introduced in the vehicle by which energy reuse can be happened in the vehicle. Which can impressively reduce the emission of polluting particles from the vehicle. The impressive add-ons among this technologies are fuel cell which can reduce the rate of environment pollution near zero level. Research are going on full swing on the other green technologies like the addition solar cell in the vehicle. Due to some limitations this awaited technology is yet to reach the remote people. Recovering exhaust heat and vibration energy can be a good source of energy in the vehicle. In this paper technologies invented in various time, used in the vehicle for a greener world like regenerative breaking system, fuel cell, energy harvesting from vibration, recovering exhaust heat and the use of photovoltaic panel in vehicle are briefly discussed. Beside this the business perspective of this technologies and cost of producing power from them are discussed.
