Before the space age, astronomy text books described Uranus as being a remote ball of relatively inactive frozen gases. Nothing much could be going on there. Of course they were working under the assumption that planetary weather was caused by the interaction of the planet's characteristics and atmosphere, with the heat of the Sun. Well, though the conclusions drawn from that assumption have been proven wrong, the assumption still remains as the explanation for the cause of planetary weather:
Note that the "average distance from the Sun" is another way of saying "the heat received from the Sun."There are several factors that affect the weather on the planets: the tilt of a planet's axis (which causes the seasons), the shape of its orbit around the sun, the presence or absence of a significant atmosphere, its average distance from the Sun, and the length of its day.

So why would a planet at the distance of Neptune or Uranus have any notable activity at all? We already know that they have winds measured at more than a thousand mph, and now x rays. How does a non electric analysis explain this?
How does my dentist create x rays in his office? The answer is its Electric!
