In India only 15 percent of the vehicles(SUV's, cars, Taxis ) runs on diesel. Other vehicles which uses diesel are used for Public transport and shipment of commodities used by common man.
There can never be reduction in using of these fuels unless prices are too high for common man to afford it.
Once price is raised the price of commodities will go high. Then obviously demand will also comedown.
This might take some time but without raising the price this is not going to happen.
Dreaming for an IDEAL world is out of the question … Politicians are not SAINTS.. They are the ones who has power in our country.. And with great Power comes Great Corruption . That's how the system is designed..
And coming to the price hikes ,common people started considering that as a part of their everyday lives. Owing to the fact that the number of Diesel vehicles have increased drastically on the streets , price hikes are inevitable as long as the govt. is not sensible enough to provide subsidized fuel for public and goods transport alone and not for the Luxury cars(the percentage of Diesel usage by them has jumped from 10 to 17% in a year time) and gensets that drink a considerable amount of the fuel subsidized by the money which again comes from the common mans pocket. There are n number of factors that affect the fuel prices and x number of solutions and as Maths says , x is always the UNKNOWN.
It is not about survival of fittest. It is the question of whether subsidy is going to the right hands. What are the mechanisms that are in place for ensuring subsidy goes to the right person. Tell me given an option each of one of us will prefer to circumvent some rule so that we can get the subsidized rates. And it is not only politicians it is we the " Common Man" is also responsible for it. So unless this exists it is a fact that rich will be become rich and poor will become more poor. Reason being the deserving people are not getting the benefits and it is cornered by people who has bargaining power.
