The Source of Heat from Within Uranus

The picture shows places on Jupiter which are hot. Jupiter is a very warm place, as shown in the picture, sort of like a warm log in the fireplace which gives off heat.

Unlike Jupiter, Uranus is like a cold log in the fireplace and does not give off much heat.
