Nuclear energy in the sun, which is then transferred by radiation. The nuclear reactions are caused by colliding particles in the sun's core due to the massive gravity.

All, no. Some, definitely. Wind, solar and many other sources of energy are useful only in certain areas. I think that it's ironic that the greatest insolation on Earth is found in Saudi Arabia. However, almost all of the inhabited Earth can make some use of solar power, even during the night. Wind is more subtly regional, at least sometimes. In the USA, almost all of the Plains can make good use of wind power as a supplement. In more montane regions, topography plays a role. The tops of the hills and the valleys are best suited to harvesting wind energy; the sides of the hills, not so much. Let's not forget water power. Stream flow is continuous, except in droughts but is easiest to tap along the Fall Line. Waves can bob floats ("ducks") up and down and the energy harvested. Tides can spin turbines in a few places. There is also geothermal energy, tapping the heat of the earth or the oceans.I am told that near-surface geothermal energy is especially effective for new construction. We can also tap nuclear energy if we can dispose of spent fuel safely and harvest natural gas from landfills and wastewater treatment plants. I once saw a very simple small scale heater that consisted of a hose run through a pile of wood chips that were composting outside a small building. As I recall, the hose was pushing 140°F air into the building during the winter. Alternative sources can't do everything but they can make a sizable dent in our energy needs.

The Sun.
It burns Hydrogen. Actually by means of atomic fusion.
We will be forced eventually to do the same.
