Ah, our town installed the station and the first 3 hours is free. So, with a full charge in less than 3 hours, that's all I need. After 3 hours it's $20 an hour.LOL - no, I get that but I mean, how is it free to you? Or, why is it free to you? The electricity has to be produced by something and by someone. Who pays for the production of it and the infrastructure to allow you to take it for free?
As to the broader political discussion of the rationale for government supported installations of power stations and tax incentives for purchase to encourage electric vehicles or all the other stuff they do all over the world that can be debated (if that's what you meant), I'm leaving that out. Separate discussion.
