The music group Coldplay plans to use their fans' energy to help provide power for their musical performances and to help the environment.The band has promised to use methods that are sustainable.This includes using energy that does not add carbon gases to the atmosphere.The band hopes to cut the amount of carbon dioxide, or CO2, released by its business activities by 50 percent.The music stars have added special dance floors and energy-storing exercise bicycles to their latest world tour.The goal is to get fans to help power the show as they dance or spin by producing electricity.Bassist Guy Berryman suggested music fans will be more likely to accept changes to the concert experience if it is "a kind of opportunity to do something fun."Each special dance floor, called a kinetic dance floor, can support many people.The floor creates electricity when people move on it.The band even has competitions before its performances to find out which group of fans can create the most power.Each of the bikes can create an average of 200 watts of energy, captured in batteries that run parts of the show.
