Analog radio typically consumes less energy than music played via Bluetooth. This is because analog radio relies on a simple receiver to pick up radio waves, while Bluetooth requires a constant wireless connection and data transmission between the device and the speaker. Bluetooth technology uses more energy to maintain this connection and transmit data, making it less energy-efficient compared to analog radio. Therefore, if energy consumption is a concern, using analog radio may be a more efficient choice. **
