There were many contributers to the idea. Isaac Newton, and Galileo contributed a lot. they experimented with motion, and diagnosed kinetic energy
-
James watt also contributed to this idea, as well as Joule. Experiments with physics eventually came to the idea of potential energy.

J. Willard Gibbs was very smart. He attended Yale, and was in the physics department. He kept at it to discover Chemical energy
-
Hahn, and Staussman started out with studying atoms, and later harnessed nuclear fissoon. That led to the atomic bombs, and nuclear energy was invented.
