According to a calculation made by a Mumbai based Electrical Engineer, India can save around Rs. 245 crore a year if people stopped honking. That is enough to feed around 55 lakh poor people a month.
So how did the person come to such a conclusion? Well, SK Patel, the Engineer who came to this conclusion by matching the total number of vehicles on the road with the average number of times people honk and the electrical and diesel energy needed to charge the car battery. Simple.
Let us explain - The total number of vehicles that run on Indian roads are 74.7 crore units, including two-wheelers, four-wheelers, trucks, buses, and multi axle vehicles. The average wattage a horn consumes is 75 watts and the average time a horn is pressed for is 1.5 seconds.
This results in consuming 0.00003125 units of electricity every time a person uses the horn. Now, if a person uses the horn six times per hour, and uses the vehicle for an average of 8 hours per day, taking into account all the vehicles in India, we arrive at a calculation like this:
74,70,00,000 (vehicles) x 0.00003125 (units per honk) x 6 (times per hour) x 8 (hours a day) = 11,20,500 units/day.
Now, taking into account that one unit of electricity costs Rs. 6, we arrive at a calculation, 11,20,500 (units per day) x 6 (cost per unit of electricity) = 67,23,000 (cost per day).
Now, calculate cost per day into 356 days, that is, 67,23,000 x 365 = 245,38,95,000 (cost per year).
Patel gathered the total number of vehicles in India through various sources. So the next time you honk, remember the cost involved.
