Alternating current could fit this description.
two min types of energy are mechanical in the case of motion and electricity in which case is electricity.
electricity is formed into motion by a motor
If the natural flow of the river is turned into some kind of dam to create kinetic energy, then it can create electricity. In other words, motion can be made into power. So if you harness the natural motion of a river, you generate electricity.
A piezoelectric device can convert motion energy into electricity. These devices generate an electric charge when they are mechanically stressed or vibration is applied to them, typically through a material like quartz or ceramics.
Electricity is related to the movement of charged particles.
Electricity in motion is called electric current. It is the flow of electric charge through a conductor.
Alternate Current is one kind of electricity.
Static electricity
friction
An electric motor
A motor takes electricity and creates rotating motion. A generator takes rotating motion and turns it into electricity.
