Now days, the prices of conventional fossil fuels have hiked up and their availability is not as before. The major threats faced by the earth such as greenhouse effect, global warming, pollution are influenced by the conventional fossil fuels. At the same time, the basic commodities fundamentally required by the people of the world are mainly met out through various transportation modes.
