Now a requirement: We need to both immediately stop buying non-electric cars and quickly decrease our driving substantially. Use your cars for necessity only and not pleasure at this point especially if you want to be a large part of decreasing that carbon they are talking about. In fact, carpool whenever possible, whether work, religious activities or even mall shopping. Work on making it a habit to walk, bike, or take public transportation when feasible.
(this post in draft as I have more details to add but cannot locate at the moment…)
