Get the same hairdresser every time, explain it once. The next time you can say “same thing as last time”. Maybe some small corrections here and there, but I never have to explain my wishes anymore.

Here in NL they have a decent system if you ask me. Infrastructure for power is owned by TenneT, a semi-government organisation. Then power is supplied by private companies, from whom you can choose any one you want (aka the cheapest/greenest one, depending on your wishes). They then supply power to the national grid, so you’re technically using power from all companies, but paying your share to the one you have a contract with.

Do it in enough places and every won’t.
