The regrowing branches can be used as a biofuel 23 of 26 Fuel cell an electrochemical device that produces electricity from the chemical reaction between two substances, usually hydrogen or an alcohol, and oxygen 24 of 26 Peak shaving the process of storing surplus energy to satisfy later demand peaks 25 of 26 Half life the time it takes for half the original material to be lost 26 of 26
