Six months ago, the HOA community that I live in, Highline Crossing Cohousing Community in Littleton, Colo. went online with 19.6 worth of solar on our so-called Common House and on some of our shared garages here. I worked with other residents for 18 months to persuade residents to go solar, not an easy task in a community of 40 residents where 90% of the households have to vote in favor of a measure in order for it to pass. Yes, that is the "cohousing" ethic/approach -- cohousing is a form of living that is deliberately extra community-based and community-focuses.
To the right-wing folks who are INCORRECTLY claiming greening the grid caused the power outages in Texas: YOU ARE WRONG!
I have long been very interested in the question of how much it (does not) matter(s) when one plugs one's electric vehicle in, especially if, like I do, I have the choice of plugging into a home rooftop solar system.
Many years ago, I wrote extensively on this web site/blog about the many intricacies and complexities of what I call "solar offset" charging of an electric vehicle vs. directly filling up with electricity that has been/is being produced directly by a (home rooftop) solar system connected to the same electrical box into which an EV charger and/or the wall-socket into which you're plugging your EV into.
