At its most basic level energy is the capacity to cause motion.

Chemical energy can move your car. Thermal energy is the kinetic energy of the molecules in an object. Gravitational energy is when something moves towards another massive object.

There are deeper explanations, but if you aren’t going to learn calculus you should probably ignore them. Somebody without a very strong math background isn’t going to comprehend Noether and symmetries.
