Dirty coal and the inefficiencies associated with generating electricity, then storing it in lead-acid batteries and then turning an e-rickshaw is definitely less efficient and far more polluting than autorickshaws running on CNG.

OK, I'll bite. Cite please. Include full lifecycle costs on CNG, including fracking and shipping.

Even with all those losses, the electric vehicle road trip is still better for the climate than driving a gasoline-powered car. Burning that much coal would release about 310 kilograms of carbon dioxide into the atmosphere, compared with 350 kilograms by the 40 gallons of gasoline. Even though coal tends to emit more pollutants than oil for the amount of energy it generates, the efficiency of the electric vehicle, which recharges its battery with every brake, more than makes up the difference.
But.. the article doesn't say "CNG is better" It just says the worst-case costs in the US, for coal sourced power to charge the batteries.

In India, most of the total power used is generated by coal. And yes, natural gas beats coal-powered electricity.
Only if you disregard how natural gas is made. Fracking, and fugitive gas, and transport costs you don't seem to care about make CNG and LNG highly suspect.
