The thing is, your drinking water in Aurora already comes from reservoirs in other parts of the state that have been fracking for years. Basically if you don't like fracking, you can't live in Colorado.
I understand and grudgingly accept the risk to the drinking water. My concern is the airborne pollutants (carbon from the generators, expelled gases, VOCs) that are a certainty and how proximity relates - how close is too close.
I use home assistant to charge automatically when I want, to the level I want. Though to make it work both my charger and car are somewhat supported by hacs repos.
