It is impossible to solve climate change without government intervention. Capitalism is working, slowly, because solar and wind are cheaper. But we will hit wall where the carbon-free alternatives are more expensive. The government will need to ban gas cars at some point, or use carbon tax to make them unaffordable. Same with carbon-free concrete, big industry, natural gas appliances, and transportation. Also, we will need to do significant carbon capture, and that is pure cost. The government will need to pay for it with some kind of tax.
