This is an incredibly large number, and it's helpful to put it in perspective:
* The Sun produces enough energy in one second to power the entire Earth for millions of years.
* The Sun is responsible for almost all of the energy we use on Earth, whether it's directly from solar panels or indirectly through fossil fuels formed from ancient plants that used sunlight for photosynthesis.
This incredible power output is generated by nuclear fusion happening in the Sun's core, where hydrogen atoms fuse together to form helium, releasing vast amounts of energy in the process.
