Energy conversion is the process of changing energy from one form to another. For example, when you turn on a light bulb, electrical energy is converted into light energy and heat energy. This transformation allows us to use energy in ways that are useful for our daily activities, such as lighting our homes or powering devices. Different types of energy can be converted, including solar energy, kinetic energy, and chemical energy. In a hydroelectric power plant, for instance, the potential energy of water stored in a dam is converted into kinetic energy as it flows, which then turns turbines to generate electrical energy.
