When we use energy, it doesn't just disappear, it becomes something else. Of course, it doesn't always become something that we can actually use, but it is not simply destroyed.
Ultimately, most all of the energy we have on our planet comes from the Sun. Today we explored how we (mankind) harnesses the energy of the sun through the water cycle to light our lightbulbs. Check out the great documentary below about the building of the Three Gorges Dam in China and research the concept of the Conservation of Energy.
