GREEN TRANSPORTATION

                                                  Transportation methods that do not rely on the abating fossil fuels can be categorized as sustainable means of transportation or Green Transportation. Green vehicles rely on renewable sources of energy and those which do not have a negative impact on the environment. It is estimated that 20-25% of the world’s energy is utilized by various means of transportation. Around 95% of the road transportation vehicles depend on oil as their fuel and this accounts to 60% of the world’s oil consumption. If the current trend continues, the number of cars which are 750 million currently will double in number in the next 30 years and so will the demand for oil which will eventually lead to higher and dangerous levels of air pollution. Estimates suggest that half of the world’s accessible oil deposits were used up in the 20th century. Only in recent times has there been a change in attitude towards the efficient use of clean fuels and people have become more environmentally conscious towards the use of existing natural resources.

SUSTAINABLE TRANSPORTATION FLOWCHART

 

                                                Greener modes of travel provide good health, reduces GHG emissions and are economical. Public transportation like busses and trains are a great alternative and tends to be cheaper, convenient and quicker in major cities and creates a lesser carbon footprint than individual vehicles. Cycling provides swift transportation and is lot cheaper in cost and maintenance. Walking is great for short distances like Grocery shopping, schools, nearby work places etc. It is free and additionally a good form of exercise to the body. Trips in similar routes on regular basis by multiple occupants can be clubbed by carpooling. It tends to be a great way to save money on fuel.

HYDROGEN CELL POWERED HYBRID CAR

 

                                              Efforts and progress has been made to develop more fuel efficient means of transportation. Much research and development has taken place in experimenting different fuels to run on Green Vehicles. For eg. Hybrid cars that can save on fuel by the combined output of an electric motor and a conventional internal combustion engine. Solar power is a potential source of future energy. Though they are limited to the time of the day, solar power cells harness maximum of sunlight to convert it to useful electrical energy. In addition, study states that these solar power panels can favour in the generation of hydrogen gas on a cheaper cost. Hydrogen will be a major contributor to power the future transportation. Hydrogen is a basic earth element and is in abundance. It is non-toxic and does not create harmful carbon emissions when it is burned. It works on the reaction to oxygen and the energy output that is produced can be directed to drive an electric motor. Other such renewable sources of fuel include Nuclear Energy, Wind Energy, biofuel etc.

                                             Transportation is vital part of our lives. Energy is at the very basis of whole of our current and future modern society. The whole challenge lies in changing our core perception, keeping the future generation in consideration with an aim to incorporate a carbon footprint reducing lifestyle which will save our environment from any further degradation.
