The Sun is by far the biggest source of energy in our solar system Even here on Earth, the Sun accounts for roughly 100% of all the energy we use - fossil fuels are just ancient sunlight stored in plants, while wind, hydro, biomass, and solar power are all driven by the Sun right now Beyond Earth, the vast majority of spacecraft, satellites, and future Mars bases run entirely on solar energy The Sun puts out 3.8 × 10²⁶ watts - more energy in a single second than all of humanity has ever used in its entire history And just to put it in perspective: the Sun makes up 99.8% of the total mass of our entire solar system. Jupiter is only 0.1%. Everything else (Earth, Mars, asteroids, etc.) is basically miscellaneous We’re finally learning how to use the only energy source that actually matters ☀️
