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 lives, such as lighting our homes or powering our devices. Another common example of energy conversion is in a car engine. Here, chemical energy stored in fuel is transformed into mechanical energy, which moves the car. Understanding energy conversion helps us improve efficiency and develop new technologies that can harness energy more effectively, benefiting both our lives and the environment.
