The Sun. In the core of the sun, tiny hydrogen atoms are being fused into helium atoms. Einstein tells us with “E=mc^2” that you can turn mass into energy. One helium atom is actually lighter than 4 hydrogen atoms, so a bit of that mass gets turned into energy, which flies through space and hits the water, heating it, and turning it into a big storm.
The sun puts out far more energy than that by orders of magnitude. More energy is emitted by the sun in a day than has been used by all of humanity ever. Grant you only a tiny amount of that hits the earth but still gives a sense of scale.
In this case energy actually is created. Effectively the sun converts matter into energy just as all nuclear reactions do. The sun operates on fustian where nuclear reactors function of fission reactions but the idea is the same that matter is converted into energy. The exact science is a bit complex for the uninitiated but the sun turns hydrogen atoms (the same that make up water molecules) into energy.
