You're barking up the wrong tree. (i) systemic change on a global scale is needed, individual actions don't "matter". (ii) corporations and governments are the only entities large enough to make changes. Governments need to force companies and incentivize individuals to make better choices, and help those that would be financially disadvantaged by those choices. (iii) paradoxically, while individual actions don't "matter", they add up of course. Both in energy usuage, and in voting. The latter is more important if we want governments to force and incentivize companies and individuals to make positive changes. So giving the environmental cause a bad name by yelling at individuals for making sensible financial choices is going to cost the green cause voters, which we sorely need.
Stop it.
