Capitalism and enterpreneurship is how we got here in the first place. Elon and renewables are only becoming a thing because of economic incentives from governments - positive incentives in the form of subsidies on e.g. new EVs, solar panels, etc, and negative incentives in the form of carbon taxes.

Take those away and the "green" companies would have NO incentive to push their work. They'd be working with people wanting to do better first and foremost, and then they would - ironically - be competing with petrol and energy companies, who also have "green" all over their marketing.

Renewables and EVs could not compete without government incentives.
