Hopefully, this is intuitive to use. I have a writeup on the calculator below.

| Pollution Savings |
Over the last 12 years or so, we as a family have made an effort to be green in an effort to reduce our carbon footprint. Our first car was a Maruti Suzuki Wagon R. This was the LPG variant. LPG (Liquid Petroleum Gas) which is a mix of Propane and Butane (mostly Butane) combusts to just Carbon Dioxide and Water. There are hardly any particulate matter or NOx chemicals emitted. Although not perfect, this, we believe was a step in the right direction. Our next car, our recent purchase, is the Tata Nexon EV. This is an electric car. I built this calculator if you, like me, have been wondering how much money you've saved by switching to EV.
This calculator shows savings in two categories. How much money you saved and how much pollution was prevented. Calculating pollution is a bit tricky because even
though an EV itself does not have any emissions of its own, the source of electricity does have emission consequences. This calculator accounts for this as well.
The combustion data for different the different fuels was taken from this location.
A copy of this report has been saved on my server here.
The sources of electricity for different states is taken from
this location. A local copy of this has been saved on my server here.
And yes, in case you are wondering, the fuel prices are prices as of the current date.
