Originally, all the energy on the Earth, in the universe, really, came from the "Big Bang".
Early giant stars that went supernova created all the various elements, which coalesced into the planets making up the early solar disc.
This material, by Accretion, formed into the planets around a large ball of hydrogen which later became the sun.
This accretion, known as a bombardment, imparted the energy of these impacts into frictional heat energy. A secondary "great catastrophe" which formed the moon imparted more heat to the Earth.
Radioisotopes impart a small amount of heat to the inner planet, but this is naturally decreasing as the elements break down into more stable elements.
The gravitational (tidal) pull of the moon, and to a lesser extent the sun, also imparts some frictional heat to the Earth.
The remaining energy on the Earth has been transmitted by heat radiation from the sun, which, for the last 4 billion years or so, has been shining on the Earth.

The Sun is the primary source of all energy on Earth.
Nearly all energy on the earth comes originally from the sun - including fossil fuels. To the best of our knowledge, fossil fuels come from the conversion of deposits of matter that was once living into the fuel via lots of pressure, heat, and time after it was buried deep in the crust. The plants that contribute to the fossil fuels got their energy from the sun via photosynthesis. The animals got their energy ultimately from the sun by eating plants that got their energy from the sun by photosynthesis or other animals that ate the plants that got their energy from the sun by photosynthesis.
Nearly all of the energy that reaches Earth's surface comes from the sun.
From Earth's rotation. Therefore, if tidal energy is used - or not used, but just wasted in friction - Earth will gradually rotate slower and slower.

All energy in any ecosystem originally comes from the sun. the energy is then passed on to the producers. including plants, trees, and anything else that uses photosynthesis.
All earth's energy comes from the sun.
The Sun, unless it is geothermal energy (heat form the Earth's core) which originates from radioactive decay.
From the sun, gravity, and the heat from the interior of the planet.
It doesn't come all from one source. The energy come from wind, earth's rotation and ocean currents
Ultimately, it all comes from the Sun.

Because almost ALL sources of energy on Earth derived originally from sunlight. (Exceptions are gravity sources [earthquakes] and thermal vents.]
