Many states offer their own incentives on top of federal ones, so it really can vary quite a bit depending on where you live. For example, some states offer rebates at the point of sale, while others provide tax credits or grants. It's worth checking your state's DMV website or energy office for specifics. Some programs have limited funds, so applying as early as possible can help. Additionally, keep in mind that these subsidies can change from year to year based on new budgets or policies, so staying updated through reliable online resources or forums can be really helpful.
