Some of it's political forces and some of it's technological forces. The global supply chain is moving away from combustion and it's not going back. Those are just overall technological trends the global market is demanding. Companies need to continue delivering better products that are cheaper, lighter, more reusable, etc. People aren't buying electric lawnmowers because of some government mandate; they're buying them because they're quiet and less maintenance. It's only now they're able to produce them with enough battery power and at a price people can afford them. And it's not just the US either. Some countries these products are sold in don't even have refineries. The common denominator globally is electricity.
Some of the tax breaks are good and some are bad. I feel like EV's need to prove cost effectiveness, range, and charging infrastructure before we're encouraging everyday Americans to buy them. So I think the $7500 Federal credit should wait. But I think it's good the Federal government is encouraging domestic battery production with the IRA.
