-splitting water to make hydrogen
-flywheels
-pumping water to be released later
-compressing air to be released later
-batteries (gradually lose charge)
-melting something that maintains its heat well, to later be used to generate steam
-making ethanol from plant shit
-hydraulics
-refining oil
-(sort of) making silicon
-can be used to make PV panels
-(sort of) making aluminum
-aluminum can be used to replace several metals; aluminum ore is abundunt
