The Amish have have electricity - they can't be tied to the ground at all. No basements, no foudations on their houses . No electricity because the poles are tied into the ground. Being below ground was to tempt death.
They run generators. That, and culturally they just aren't to into electricity. If they need lighting, then they will use it. Cars go too fast. I used to give the Amish rides into town all the time.
