In order if consumers to make wise environmental choices, good options have to be widely available, (they are not), and we have to know which experts to believe in telling us what the best options are (we don't (or at least we can't agree on who we should listen to)).
Those two things have been deliberately obscured so we would have to do a lot of independent research to figure things out. The typical person is too concerned about meeting day to day needs to spend significant time pondering who is lying and who is not. They just respond to whoever speaks to their immediate concerns.
Our choices have been deliberately limited and false information provided to confuse the situation.
Yes, the truth is slowly coming out and more options are becoming available but most of those options won't be available to the majority even in 2020. Even at $25,000 most can't afford a new car. It won't be until 2025 or later that most of us will really have a choice other than fossil fuels and a few years later that fossil fuels are no longer the default choice.
This is because of the efforts of fossil fuel companies to deliberately limit choices and hide the harms for the last half centry, not because of consumer choices.
