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 ☀️

It's not magic but a chemistry ⚗️ that we are yet to understand.

 The number that stops me every time is this one.

The Sun has been burning for 4.6 billion years. It has enough hydrogen left to burn for another 5 billion. And in that entire lifespan it will convert less than 0.1 percent of its total mass into energy.

That is how catastrophically inefficient fusion actually is at stellar scale.

The energy reaching Earth is already filtered down to roughly one billionth of total solar output. We intercept a fraction of that fraction. And it is still thousands of times more than everything human civilization currently consumes.

The conversation was never about whether there is enough energy. There has always been enough energy.

The only question was always whether we would build the infrastructure to catch it before we burned through the stored version.

We spent 200 years choosing the copy over the original.
