Are electric vehicles really GREEN?

Image
We are in the stage of transition towards electric vehicles from traditional ICE (Internal Combustion Engine) cars. Each and every automobile brand in the world are now launching EVs and are planning to make their line up fully electric by 2030 or above. New start-up companies other than legendary car makers are also going to pump out electric cars. All these legendary brands and start-ups are saying only one thing, "EVs are green!"  Do they really pollute less than ICE vehicles? Let's see! Overview In this blog, I will try my best to make you understand the calculation done and make a clear statement. All the average data are obtained from Google search.

(28*13=364 days)   This is same in the case of 3months validity (actually 84 days)   So how can we save our money from this business men's strategy? If you subscribe for an year, you will be saving more money. Here how it is, In Jio, 2GB/ day subscription for a month costs 249 rupees. The same 2GB/ day subscription for a year costs 2399 rupees. If you are not aware of this strategy, you will be recharging 13 times a year, i.e 13*249= 3237 rupees. If you are recharging for a year, you will be paying 2399 rupees. So you can save 838 rupees.  Like wise comparing 2GB/day an...
