Hogwarts is not the only wizarding school , Bouboutin for example , is explicitly mentioned , and as we know from the Cursed Child , there ' s also a school in America . I assume that there are schools in every major geographical region . This doesn ' t actually help matters since the dramatis personae of the books are overwhelmingly British in nationality . That is , there are certainly other schools in other regions , but they don ' t all donate all their graduates to the English wizarding society . <| sep |> I actually laughed out loud . Great story <| sep |> Sure , let ' s take a look at all the cost of making said battery every 10 km , and the cost of the trains , etc probably made in a country without regulated emissions standard for their factory , the gathering of raw material , etc it becomes a bit more complicated . I ' m with you that with more maturity , a better view point from the general public in general , as well as global participation , we can get better as fast as the gasoline age . But I think a clear consideration of all aspects and not just the short term gain . For example , I thought about turning my home and making it close to net zero envision , so solar panels going to a battery and feeding the system with excess electricity . It ' s not as costly and effective as I had initially thought , kinda the same exercise I ' m doing now regarding our initial thought on pushing for renewable energy now
