Yes, a machine can convert mechanical energy into hydraulic energy (i.e., pump water up), and a machine can convert the hydraulic energy into mechanical energy. Some energy will be wasted in both cases, meaning that if you try to do this "back and forth" several times, the total energy available will decrease.
a mechanical energy is a kind of energy
electrical to mechanical
Nikola Tesla was a famous US physicist that created mechanical energy which is used today in hydropower. He invented this machine in 1856.
Stored mechanical energy to mechanical energy
mechanical energy is equal to the kinetic energy + potential energy "gravitational,elastic"
It is mechanical energy.
An engine converts energy into mechanical motion.
the turbines in hydroelectricity projects convert mechanical energy into electrical energy.
