Mechanical Energy consists of two types of energy - the kinetic energy (energy of motion) and the potential energy (stored energy of position). The total mechanical energy is the sum of these two forms of energy. In a previous part of Lesson 1, it was said that work is done upon an object whenever a force acts upon it to cause it to be displaced.

However, as an alternative, pumped-hydro storage (PHS) is an eco-friendly energy storage system which can provide a more sustainable solution [9], [10], [11]. A PHS is comprised of two reservoirs, a pump, and a hydro turbine, storing electrical energy in the form of gravitational potential energy.
