Different Types of Energy Storage and FAQs
Energy storage can be defined as the process in which we store the energy that was produced all at once. This process helps in maintaining the balance of the supply and demand of energy. The method of using wind to generate electricity is known as wind energy. The kinetic energy in the wind is converted into mechanical power by wind
