Most people are aware that electriccars are far more energy-efficient than traditional fuel-burning cars.However, what they may not realize is that once they have bought anelectric car, the music they listen to while driving also affects theirenergy consumption.       An experiment conducted by a South Korean car manufacturerin 2022 invited a number of drivers to drive their new electric cars. Thecompany asked the drivers, who were all new to electric vehicles, todrive their cars over an 18-mile distance, inclusive of a traffic jammoving along at a glacial pace, country roads and expressways withdual lanes.      Some of these drivers were instructed to listen to Beethovenwhile driving. Others were required to listen to a range of pop artists,such as Kanye West and Adele. The results revealed that the relaxingnature of Beethoven’s music resulted in those cars using less batterypower than the cars whose drivers listened to pop music. This is becausepop music tends to have a higher tempo and heavier beat.       So, if you own an electric car but still want to make a greaterenvironmental contribution, you can listen to your favorite piece ofclassical music. _____, if you don’t care about power consumption andwant to drive faster, just put on some fast-paced pop tracks!
