I think a more likely way of changing usage patterns is by actually pricing carbon cost into energy production and manufacturing via taxes. The costs of things are only so low because we are borrowing from the future. I don't think a mindset shift will happen under capitalism without the monetary cost of things increasing. And I don't think capitalism will change unless by collapsing, at which point we're too late anyway, and would come with much human suffering. I don't believe that capitalism is fundamentally broken, but I do believe that unchecked capitalism is. Regulation and taxes are required to manage its negative tendencies.
