How much of all current energy on earth arrived as sunlight vs. as kinetic energy during formation? For example, sunlight captured by plants would count in the &quot;arrived as sunlight&quot; category, whilst heat energy in the core of the earth would count in the &quot;kinetic energy during formation&quot; category.
We can try to compare sunlight energy arriving from the Sun and geothermic energy coming from the Earth's interior.
The Earth gets about 340 W/m2 from the Sun(1) while the average geothermic flux is about 0.1 W/m2.(2) Therefore, the current energy of sunlight is way larger than that from kinetic energy during Earth formation.
Additionally, it should be noted that a large part of geothermic energy doesn't come from Earth cooling by getting rid of its formation heat but from radioactive decay, making the comparison with sunlight even more one sided.
