Solar energy converts energy from the nuclear reactions in the sun into electricity.
There is a nuclear reaction going on in the center of the planet Earth too. We would not be able to live without this process. It would be too cold and too much radiation would reach us from space.
There is a hot iron-nickel ball rotating in the center of the Earth. It creates magnetic field around our planet, which protects us from space radiation. Fortunately, the radiation from the nuclear process at the center of the Earth does not reach us either.
In principle, any energy has its source in a natural nuclear reaction one sort or another.
Dynamically binding, you realize the magic. Statically binding, you see only the hierarchy.
