What are the ultimate sources of all of Earth's energy?

Most of Earth's energy comes from the sun. We can harness energy from the sun's radiation directly, but solar radiation also makes possible several other energy sources. Solar radiation drives wind patterns and the hydrologic cycle, and plant growth gives us wood to burn. A great deal of energy also emanates from Earth's core, enabling us to harness geothermal power. A much smaller amount of energy results from the gravitational pull of the moon and sun. An immense amount of energy resides within the bonds among protons and neutrons in atoms, and this energy provides us with nuclear power.
