Wireless energy transmission is a way to get energy from one place to another without using wires or plugs. Instead of using wires or plugs to send energy from a power source to something like an electric vehicle or a lightbulb, wireless energy transmission sends energy by using a type of energy called radio waves. Radio waves are a type of invisible energy that can move through air, like sound waves. Wireless energy transmitters send out powerful radio waves that transfer the energy from the power source to the device that needs it, like an electric vehicle. When the energy reaches the device, it is converted into the energy that is needed by the device, like electricity. This means we don't need to plug things in to get energy anymore, because we can just use wireless energy transmission.
