Konserbasyon han enerhiya

An balaud han konserbasyon han enerhiya amo an usa ka balaud empiriko han pisika. Sumala han balaod, an ngatanan nga enerhiya nga ginbulag nga sistem nagpapabilin nga konstant o waray pagbabag-o han pag-agi han panahon. Ginpapasabot hini nga balaod, nga an enerhiya diri nahihimo o naruruba. An puydi la mahitabo ha enerhiya ha sarado nga sistema amo la an pagbalyo an porma sugad han pagbalyo tikang ha kimikal nga enerhiya pakadto ha thermal nga enerhiya.
