Yes, the only way that intentionally purchasing renewable energy matters is once it goes over the amount that would be renewable anyways.
Like if NC is already 10% renewable and 90% coal, the energy company can sell 10% of it as renewable-only without changing a single thing. It just means the average consumer goes from 10% renewable to 0% renewable.
Electricity is fungible. The power company cannot possibly serve a customer renewable electrons from the grid. This whole thing is absurd and Apple should be ashamed for making the claim.
